Question

I have a link that i want to execute a query to the database after it’s clicked and then reload the page. From what i read, it could be done using javascript, but i can’t figure it out.

EDIT

Forgot to mention that i want to send 4 variables to the script and i can’t use GET because i have htaccess set to modify my URL.

In this case you need to use these concepts:

1. A JavaScript function to submit the from values
2. PHP code

You need to user these code:

 <a href = "javascript:submit()">Submit</a>
 <form action = "$_SERVER['PHP_SELF']" method = "post">
 <input type = "hidden" value = "some value"/>
 <input type = "hidden" value = "some value"/>
 <input type = "hidden" value = "some value"/>
 <input type = "hidden" value = "some value"/>
 </form>
<?php
//Connect to the database
$conn = mysqli_connect('host','user','password','db_name');
if($conn){
     $query = "SOME QUERY";
     $result = mysqli_query($conn, $query);
}
?>

In your JavaScript function write a code to submit the from clicking the submit link.
