</pre>


<h2>$this->examples_model->form_fields(<var>[values]</var>, <var>[related]</var>)</h2>
<p>Somewhat similar to the table_info method with difference being that the returned array has information for creating a form.
The related parameter is used to conveniently map other model information with this form to create a many to many multi-select form element.
This method is usally used with the <a href="<?=user_guide_url('libraries/form_builder')?>">Form_builder</a> class.
</p>

<pre class="brush: php">
$form_info = $this->examples_model->form_fields();

echo $table_meta['description']['type']; // textfield 
echo $table_meta['active']['type']; // select or enum 
echo $table_meta['date_added']['type']; // datetime (a special field type in the form_builder class)

<h1>Inline Editing</h1>
<p>Inline editing allows users to quickly modify module information within the context of the website. This is accomplished by using
either the <a href="<?php 
echo user_guide_url('helpers/fuel_helper');
?>
">fuel_edit</a> or the <a href="<?php 
echo user_guide_url('helpers/fuel_helper');
?>
">fuel_var</a> function with the latter
specific to pages that are completely editable (and not just module data).
</p>

<p>For inline editing to work, you must be logged into FUEL and have the proper permissions to edit the page or module information. 
A <span style="background: transparent url(<?php 
echo img_path('ico_pencil.png', FUEL_FOLDER);
?>
) no-repeat; display: inline-block; height: 16px; width: 16px;"></span> pencil icon
will appear over editable areas when the editing for the page is toggled on. Clicking on the icon will overlay a form over your page to edit the values in context.</p>

<h2>Page Inline Editing</h2>
<p>Page inline editing allows you to edit the values of variables used in the page.
A FUEL logo will be displayed in the upper right area of the page that can slide out and provide you 
the ability to toggle inline editing, publish status and caching. Clicking the inline editing pencil will toggle inline editing on.</p>
<img src="<?php 
echo img_path('examples/page_inline_editing.jpg', 'user_guide');
?>
" class="screen" />

<h2>Module Inline Editing</h2>
<p>For those pages that may not be editible, you can still allow for module data to be edited (e.g. news items).
The top right area <strong>will not</strong> have the controls for page publish status, caching or layouts and will look like the following:</p>

echo user_guide_url('helpers/fuel_helper');
?>
">fuel_model and fuel_block</a> helper functions that could be used instead.</p>


<h3>Inline Editing</h3>
<p>The very last thing we will do is add inline editing to our view. To do this we use the <a href="helpers/fuel_helper">fuel_edit</a> function. We'll
place that function right inside the &lt;h2&gt; tag. </p>

<pre class="brush: php">
...
&lt;h2&gt;&lt;?=fuel_edit($article-&gt;id, 'Edit: '.$article-&gt;name, 'articles')?&gt;&lt;?=$article-&gt;title?&gt;&lt;/h2&gt;
...
</pre>

<p>Additionally, you may add items in the context of a page. To do that, you pass <dfn>create</dfn> as the first parameter.</p>
&lt;h2&gt;&lt;?=fuel_edit('create', 'Create', 'articles')?&gt;&lt;?=$article-&gt;title?&gt;&lt;/h2&gt;

<p class="important"><a href="<?php 
echo user_guide_url('general/inline-editing');
?>
">Click here for more on inline editing</a></p>

<p>Add the following module to the <dfn>application/config/MY_fuel_modules.php</dfn> file: </p>
<pre class="brush: php">
$config['modules']['news'] = array(
	'preview_path' => 'news/{slug}'
);
</pre>


<h3 id="view_file">View File</h3>
<p>You could use a controller to do the url segment logic but for this tutorial, we will just use a single view. 
The following view file uses the <a href="<?php 
echo user_guide_url('helpers/fuel_helper');
?>
">fuel_model</a> and 
<a href="<?php 
echo user_guide_url('libraries/my_model/data_record_class_functions');
?>

<pre class="brush: php">
&lt;?php 
$slug = uri_segment(2);
if (!empty($slug))
{
	$news_item = fuel_model('news', array('find' => 'one', 'where' => array('slug' => $slug)));
	if (empty($news_item)) show_404();
}
else
{
	$news = fuel_model('news');
}
?&gt;

</p>


<h2>fuel_edit(<var>id</var>, <var>[label]</var>, <var>[module]</var>, <var>[xOffset]</var>, <var>[yOffset]</var>)</h2>
<p>Sets a variable marker (pencil icon) in a page which can be used for inline editing.
The <dfn>id</dfn> parameter is the unique id that will be used to query the module. You can also pass an id value
and a field like so <dfn>id|field</dfn>. This will display only a certain field instead of the entire module form.
The <dfn>label</dfn> parameter specifies the label to display next to the pencil icon.
The <dfn>xOffset</dfn> and <dfn>yOffset</dfn> are pixel values to offset the pencil icon.
</p>


<h2>fuel_cache_id(<var>[location]</var>)</h2>
<p>Creates the cache ID for the fuel page based on the URI. 
If no <dfn>location</dfn> value is passed, it will default to the current <a href="<?php 
echo user_guide_url('my_url_helper');
?>
">uri_path</a>.
</p>


<h2>fuel_url(<var>[uri]</var>)</h2>
<p>Creates the admin URL for FUEL (e.g. http://localhost/MY_PROJECT/fuel/admin).</p>


<h2>fuel_uri(<var>[uri]</var>)</h2>
<p>Returns the FUEL admin URI path.</p>


<h2>fuel_uri_segment(<var>[seg_index]</var>, <var>[rerouted]</var>)</h2>
<p>Returns the uri segment based on the FUEL admin path.</p>

">allowed by default</a>, however you can use FUEL's
<a href="<?php 
echo user_guide_url('parsing');
?>
">parsing syntax</a>. Page variables can be <a href="<?php

<h2>Importing Existing Views</h2>
<p>If you are using <a href="<?php

?>
">Opt-in Controllers</a>, 
a view file that matches the URI location will trigger a prompt to import that view to edit if the modified date is after the pages last modified date.
This is a convenient way to make edits outside of the admin interface and import them.</p>

<h2>Installation</h2>
<p>One of the bigger changes in FUEL v1.0 was the removal of all the extra bundled advanced modules. The reason was to keep the initial FUEL install
smaller, as well as provide separate GIT repository versioning and issue tracking for each. 
A list of some available modules can currently be found at <a href="https://github.com/daylightstudio" target="_blank">https://github.com/daylightstudio</a>.
Because of this change, it was deemed necessary to make the installation and updating process of advanced modules a little easier going forward. </p>


<h3>Using GIT Submodules</h3>
<p>We like to lean on GIT as much as possible for the updating of advanced modules and so we've added a couple command line tools to make this a little easier. 
The first is to use GIT to add a <a href="http://git-scm.com/book/en/Git-Tools-Submodules" target="_blank">submodule</a> to your installation in your <span class="file">fuel/modules/{module}</span> folder. 

// !!! IMPORTANT ... NOW ASSIGN THIS TO THE MAIN "layouts"
$config['layouts']['main'] = $main_layout;
</pre>

<p class="important"><strong>What is all this other stuff in the "Sections area"?</strong> We added this to the example just to show how complicated you can get with the layouts. The above is using 
several new features including the addition of the class "tabs" which can be applied to a "type" of "fieldset" and creates tabs for your forms automatically. We are also
displaying the new field type of "template", which gives you the power to easilty create complicated repeatable forms that you can reorder and nest inside other forms. 
For more details visit the <a href="#">Form_builder</a> page.</p>




<h2 id="layouts_custom_classes">Custom Layout Classes</h2>
<p>Occasionally, you may need a layout that does some additional variable processing before being applied to the page. To accomplish this, you can create your own 
Layout class by extending the <a href="<?php 
echo user_guide_url('libraries/fuel_layouts#fuel_layout');
?>
">Fuel_layout</a> class and modifying the <dfn>pre_process</dfn> and/or <dfn>post_process</dfn> method hooks. The <dfn>pre_process</dfn> 
method gets passed the array of variables used to generate the page (e.g. formatting of dates). 
The <dfn>post_process</dfn> method gets passed the final rendered output in case you want to do any post rendering of the final output (e.g. appending tracking scripts).
You can tell FUEL where to look for the class by specifying <dfn>file</dfn>, <dfn>class</dfn>, <dfn>filepath</dfn> and <dfn>filename</dfn> parameters as displayed below:
</p>

<pre class="brush:php">
$config['layouts']['main'] = array(
	'class'		=> 'Main_layout',
	'filepath' => 'libraries',
	'filename' => 'Main_layout.php',
	'module'  => 'app',
	'fields'	=> array(
		'Header' => array('type' => 'fieldset', 'label' => 'Header', 'class' => 'tab'),

				This line will add the menu item in the admin.
			</li>
			<li>In the constants folder its a good idea to create the following constants (although not required)
				<ul>
					<li><strong>{MODULE_NAME}_VERSION</strong> - the version number of the module</li>
					<li><strong>{MODULE_NAME}_FOLDER</strong> - the folder name of the module</li>
					<li><strong>{MODULE_NAME}_PATH</strong> - the full directory path to the module folder</li>
				</ul>
			</li>
			<li>In the routes file, add the fuel routes you want to use. For example, this <strong>user_guide</strong> module has the following routes:
				<ul>
					<li>$route[FUEL_FOLDER.'/tools/user_guide'] = 'user_guide';</li>
					<li>$route[FUEL_FOLDER.'/tools/user_guide/:any'] = 'user_guide/$1';</li>
				</ul>
			</li>
		</ul>
	
	</li>
	<li>Create your controller files. 
		<ul>
			<li><strong>Admin Controllers</strong> - Pages that need to be displayed in the admin interface should inherit from the <dfn>fuel/libraries/Fuel_base_controller.php</dfn> and can use the <dfn>_validate_user()</dfn>, protected controller method.</li>
			<li><strong>Dashboard Controller</strong> - If you add a controller with the name of <dfn>Dashboard</dfn>, then it can get pulled in to the FUEL admin (if the module is in the fuel $config['dashboards'] configuration)</li>
		</ul>
	</li>
	<li>Create your assets folder and add any specific styles you want to use for that module's admin interface in a <dfn>css/{module_name}.css</dfn> file including your menu item icons.</li>
	<li>If you have the <a href="<?php 
echo user_guide_url('modules/tester');
?>
">Tester</a> module, you can add your tests to a <dfn>tests</dfn> folder.</li>
	<li>If you have this <dfn>user_guide</dfn> module installed, you can add documentation to the <dfn>views/_docs/</dfn> folder. There needs to be at least an <dfn>index.php</dfn> file before it will appear in the <dfn>user_guide</dfn> module.</li>
</ol>

<h3>Common Controller Methods</h3>
<p>There are two main jQX controller methods that you may want to override in your controller:</p>
<ul>
	<li><strong>items:</strong> the jQX controller method used for the list view of the module</li>
	<li><strong>add_edit:</strong> the jQX controller method used for adding/editing module data (the form view)</li>
</ul>
<p class="important">It's important to call use <dfn>this.super()</dfn> to call the parent method if overwriting.</p>

<h3>jQX Configuration Parameters</h3>
<p>The following jqx config parameters are available for you to use in your jQX controller:</p>
<ul>
	<li><strong>jqx.config.basePath:</strong> The equivalent value to the <a href="http://codeigniter.com/user_guide/helpers/url_helper.html" target="_blank">site_url()</a> CI function </li>
	<li><strong>jqx.config.jsPath:</strong> The path to the fuel modoules javascript folder which is <span class="file">/fuel/modules/fuel/assets/js/</span></li>
	<li><strong>jqx.config.imgPath:</strong> The path to the fuel modoules images folder which is <span class="file">/fuel/modules/fuel/assets/images/</span></li>
	<li><strong>jqx.config.uriPath:</strong> The equivalent to the <a href="<?php 
echo user_guide_url('helpers/my_url_helper');
?>
">uri_path()</a> function</li>
	<li><strong>jqx.config.assetsImgPath:</strong> The path the sites images (e.g. <span class="file">/assets/images/</span>)</li>
	<li><strong>jqx.config.assetsPath:</strong> The path the sites images (e.g. <span class="file">/assets/</span>)</li>
	<li><strong>jqx.config.assetsCssPath:</strong> The path the sites images (e.g. <span class="file">/assets/css/</span>)</li>
	<li><strong>jqx.config.controllerName:</strong> The global name of the controller object which can be used by other scripts after the page is loaded. The default is "fuel"</li>
	<li><strong>jqx.config.jqxPath:</strong> The path to the jQX library which is <span class="file">/fuel/modules/fuel/assets/js/jqx</span></li>
	<li><strong>jqx.config.controllerPath:</strong> The path to the controller</li>
	<li><strong>jqx.config.pluginPath: The path to the jQuery plugins</strong></li>
	<li><strong>jqx.config.fuelPath:</strong> The path to the FUEL CMS which by default is <span class="file">fuel/</span></li>
	<li><strong>jqx.config.modulePath:</strong> The path to the module which is <span class="file">fuel/{module}</span></li>
	<li><strong>jqx.config.cookieDefaultPath:</strong> The server folder path used when assigning cookies</li>

</p>

<ul>
	<li>list_items()</li>
	<li>tree()</li>
	<li>form()</li>
</ul>

<p>Additionally, there are <a href="<?php 
echo user_guide_url('libraries/my_model#hooks');
?>
">several hooks</a> you may want to use that allow you to insert functionality during the saving and deleting process of a modules record.</p>

<h2>The Views</h2>
<p>Simple modules are made up of several views:</p>
<ul>
	<li><a href="<?php 
echo user_guide_url('general/interface#list_view');
?>
"><strong>List view</strong></a> - where you can filter and select from a list and edit, delete or preview.</li>
	<li><a href="<?php 
echo user_guide_url('general/interface#edit_view');
?>
"><strong>Form view</strong></a> - the form view that allows you to edit or input new records for the module</li>
	<li><strong>Tree view (optional)</strong> - provides a tree like hierarchical structure. Requires a tree method on the module's model that follows the hierarchical <dfn>Menu</dfn> structure</li>
	<li><strong>Preview view (optional)</strong> - the URO to the website to preview the module</li>
</ul>

	<li>{pdf_path('my_pdf.pdf')} - Maps to the <a href="<?=user_guide_url('helpers/asset_helper')?>">pdf_path()</a> function. The <dfn>.pdf</dfn> extension is optional.</li>
	<li>{safe_mailto('[email protected]', 'text')} - Maps to the  <a href="http://codeigniter.com/user_guide/helpers/url_helper.html" target="_blank">safe_mailto()</a> function.</li>
	<li>{redirect('my_redirect_page')} - Maps to the <a href="http://codeigniter.com/user_guide/helpers/url_helper.html" target="_blank">redirect()</a> function.</li>
	<li>{show_404} - Maps to the <a href="http://codeigniter.com/user_guide/general/errors.html" target="_blank">show_404()</a> function.</li>
</ul>

<h2>Namespaced Functions</h2>
<p>The following are namespaced functions that can be used in your application and will be translated by the templating system.</p>

<ul>
	<li>{uri_segment(1, true/false)} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">uri_segment(n)</a> function.</li>
	<li>{fuel_var} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">fuel_var()</a> function.</li>
	<li>{fuel_model(model, array(key="val"...)} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">fuel_modules()</a> function.</li>
	<li>{fuel_block(array(key="val"...))} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">fuel_block()</a> function.</li>
	<li>{fuel_nav(array(key="val"...))} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">fuel_nav()</a> function.</li>
	<li>{fuel_edit(id, label, module, xOffset, yOffset)} - Maps to the <a href="<?=user_guide_url('helpers/fuel_helper')?>">fuel_edit()</a> function.</li>
</ul>
<p class="important">Note that several of the functions require an associative array paramter with the <dfn>key="val"</dfn> syntax.</p>

<h2>Blocks</h2>
<p>Tag pairs allow you to loop through arrays of data. The syntax requires an opening <dfn>{my_var}</dfn> and closing <dfn>{/my_var}</dfn> tag. 
For example:</p>

<pre class="brush:php">
$my_data = array();
$my_data[] = array('name' => 'Darth Vader', 'weapon' => 'light saber');
$my_data[] = array('name' => 'Han Solo', 'weapon' => 'blaster');
...
{loop $my_data}
	{$name} - {$weapon}
{loop}

echo user_guide_url('helpers/my_language_helper#func_detect_lang');
?>
">detect_lang()</a> function detects any specified language settings pulling from the URI, query string and then the user's browser settings.</p>

<h2>Form_builder Class</h2>
<p>The <a href="<?php 
echo user_guide_url('libraries/form_builder');
?>
">Form_builder class</a> is used throughout FUEL CMS to create the forms used to manage module data. To allow for the localized labels in the module forms, the <var>lang_prefix</var> property can be used and will look for labels in language files using the format <var>form_label_{literal}{field_name}{/literal}</var>, if not label value is supplied.</p>

<h2>Data_table Class</h2>
<p>Similar to the Form_builder class, the <a href="<?php 
echo user_guide_url('libraries/data_table');
?>
">Data_table class</a> also has a <var>lang_prefix</var> property. This prefix is used for localizing the table column headers. The prefix is set in FUEL to be the same as the Form_builder's which is <var>form_label_</var>.</p>


<h2>The js_localized Module Property</h2>
<p>The <a href="<?php 
echo user_guide_url('modules/simple');
?>
">js_localized</a> property can be added to your modules if you have have javascript that needs to use some localized text. 
	You can provide it an array of language key values and it will be added to the list of language keys that get translated into a JSON object for your javascript files to consume. 
	If you are using a <a href="<?php 
echo user_guide_url('general/javascript#jqx');
?>
">jqx</a> type controller that extends the BaseFuelController.js, 
	there will be a <var>localized property</var> and a lang() method on the controller that provides access to the JSON language object.</p>

<h1>Data Record Class Function Reference</h1>
<p>The Data_record class is the custom record object for the Table Class parent model (MY_Model). 
This provides a greater level of flexibility with your models by allowing you to create not only
methods on your model to retreive records from your datasource, but also the ability to create
derived attributes and lazy load other objects with each record returned.
This class is <strong>optional</strong>. If it it doesn't exist, then the Table Class parent model
will use either a standard generic class or an array depending on the return method specified.
</p>

<p class="important">Most module records in FUEL extend the <a href="<?=user_guide_url('libraries/base_module_model')?>">Base_module_record</a>
class which has some extended functionality for module records.</p>


<h2>$example_record->is_initialized()</h2>
<p>This method returns either <dfn>TRUE</dfn> or <dfn>FALSE</dfn> depending on if the record class has been properly intialized.</p>

<pre class="brush: php">
$record = $this->examples_model->create(); 
$record->is_initialized(); // Returns TRUE
</pre>

<h2>$example_record->set_fields(<var>fields</var>)</h2>
<p>Sets the fields of the oject ignoring those fields prefixed with an underscore.</p>

<pre class="brush: php">
$fields = array('id', 'name', 'email');
$record = $this->examples_model->set_fields($fields); 
</pre>

<h2>$example_record->id()</h2>
<p>Returns the id field name.</p>

<h1>Module Forms</h1>
<p>Modules use the <a href="<?php 
echo user_guide_url('libraries/form_builder');
?>
">Form_builder</a> class to create the form used to create and edit module information. 
You can modify a model's <a href="<?php 
echo user_guide_url('libraries/my_model');
?>
">form_fields()</a> method to customize the form.</p>

<h2>Trigger CSS Classes</h2>
<p>There are some special CSS classes that will trigger extra functionality with certain fields:</p>
<ul>
	<li><strong>add_edit</strong> - the <dfn>add_edit</dfn> CSS class allows you to add and/or edit another module directly in the module's form. This class works on select fields.</li>
	<li><strong>asset_select [pdf, css, js]</strong> - the <dfn>asset_select</dfn> CSS class allows you input asset file names into your form fields. 
	You can specify an optional second class to specify the specific asset folder (.e.g. 'class' => 'add_edit pdf'). The default asset folder is the <dfn>images</dfn> folder. This class works with text input fields.</li>
	<li><strong>multiple</strong> - the <dfn>multiple</dfn> CSS class allows you to add multiple files at a time. Works on file upload fields.</li>
</ul>

<p>Conversely, there are a couple CSS classes that are used to remove certain functionality.</p>
<ul>
	<li><strong>no_editor</strong> - the <dfn>no_editor</dfn> CSS class is used when you don't want to apply a MarkitUp editor to your text field.</li>
	<li><strong>no_combo</strong> - the <dfn>no_combo</dfn> CSS class is used when you don't want the combo box used and instead want a regular multi-select field.</li>
</ul>

<h1>Backup Documentation</h1>
<p>The Backup module can be used to backup the FUEL database as well as the <dfn>assets</dfn> folder.
It comes with a controller to backup the database with options to include the assets folder as well as email it as an attachment. 
The Backup module can be used along with the <a href="<?php 
echo user_guide_url('modules/cronjobs');
?>
">Cronjobs module</a> to do periodic backups.</p>

<h2>Backup Configuration</h2>

	<li><dfn>backup_file_prefix</dfn> - used for the name of the backup file. A value of AUTO will automatically create the name.</li>
	<li><dfn>backup_assets</dfn> - determines whether to backup assets by default.</li>
	<li><dfn>backup_cron_email</dfn> - the email address to send the cron job notification.</li>
	<li><dfn>backup_cron_email_file</dfn> - use the email address to email notifications (seperate from the cron email).</li>
	<li><dfn>db_backup_path</dfn> - used for the admin/manage/backup. Beow default looks for folder called data_backup at the same level as the system and application folder</li>
	<li><dfn>db_backup_prefs</dfn> - use the email address to email notifications (seperate from the cron email). It is an array with the following options
		<ul>
			<li><strong>ignore</strong> - list of tables to omit from the backup.</li>
			<li><strong>add_drop</strong> - whether to add DROP TABLE statements to backup file. Default is TRUE.</li>
			<li><strong>add_insert</strong> - whether to add INSERT data to backup file. Default is TRUE.</li>

<p class="important">Note that several of the functions require an associative array paramter with the <dfn>key="val"</dfn> syntax.</p>

<h3>Blocks</h3>
<p>Tag pairs allow you to loop through arrays of data. The syntax requires an opening <dfn>{my_var}</dfn> and closing <dfn>{/my_var}</dfn> tag. 
For example:</p>

<pre class="brush:php">
$my_data = array();
$my_data[] = array('name' => 'Darth Vader', 'weapon' => 'light saber');
$my_data[] = array('name' => 'Han Solo', 'weapon' => 'blaster');
...
{loop $my_data}

echo user_guide_url('general/inline-editing');
?>
">inline editing</a> to our view. To do this we use the <a href="helpers/fuel_helper">fuel_edit</a> function. We'll
place that function right inside the &lt;h1&gt; tag in the article view and inside the &lt;li&gt; in the list view. </p>

<pre class="brush: php">
...
&lt;h2&gt;&lt;?=fuel_edit($article)?&gt;&lt;?=$article-&gt;title?&gt;&lt;/h2&gt;
...
</pre>

<p>Additionally, you may add items in the context of a page. To do that, you pass <dfn>create</dfn> as the first parameter.</p>
<pre class="brush: php">
&lt;h2&gt;&lt;?=fuel_edit('create', 'Create', 'articles')?&gt;&lt;?=$article-&gt;title?&gt;&lt;/h2&gt;
</pre>
<p>Next, make sure the FUEL bar located in the upper right of the page has the pencil icon toggled on. You should now see pencil icons that when clicked, will allow you to edit or add article data from within the context of the page.</p>

<h1>Data Record Class Function Reference</h1>
<p>The Data_record class is the custom record object for the Table Class parent model (MY_Model). 
This provides a greater level of flexibility with your models by allowing you to create not only
methods on your model to retreive records from your datasource, but also the ability to create
derived attributes and lazy load other objects with each record returned.
This class is <strong>optional</strong>. If it it doesn't exist, then the Table Class parent model
will use either a standard generic class or an array depending on the return method specified.
</p>

<p class="important">Most module records in FUEL extend the <a href="<?php 
echo user_guide_url('libraries/base_module_record');
?>
">Base_module_record</a>
class which has some extended functionality for module records.</p>


<h2>$example_record->is_initialized()</h2>
<p>This method returns either <dfn>TRUE</dfn> or <dfn>FALSE</dfn> depending on if the record class has been properly intialized.</p>

<pre class="brush: php">
$record = $this->examples_model->create(); 
$record->is_initialized(); // Returns TRUE
</pre>
