php - mysqli_query expects at least 2 parameters

Question

This mysqli_query command results in the error below

mysqli_query("INSERT INTO `counter`.`hits` (`page_hits`) VALUES (1)"); 

Warning: mysqli_query() expects at least 2 parameters, 1 given in

What does this error message mean, and how can it be fixed?

Answer 1

You need to specify the connection that you made to your database somewhere earlier in your page. You should put that variable in the query. Suppose you made a variable called $con. Then your code should be like this.

mysqli_query($con,"INSERT INTO `counter`.`hits` (`page_hits`) VALUES (1)");
