Question

I want to execute a query during onload. How do I this?
This is my code.
This is the query I want to execute.

<?php
    mysql_query("UPDATE `requests` SET `stat_id`= 3 WHERE `proj_id`='".$_GET['projid']."' and DATE(`req_date`)='".$_GET['date']."'");   
?>

and I have a javascript

<script type="text/javascript">
$(document).ready(function(){
    $('input#approve').click(function(){
        var date = $(this).parent().attr('id');
        var projid = $(this).parent().attr('class');

        window.location.href="index.php?page=requests&date="+date+"&projid="+projid+"";
    });
});
</script>

when the button approve is clicked the page is refreshed, but the query is not executing.

You can use the following code in index.php for updating table

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE Persons SET stat_id=3 WHERE proj_id='".$_POST['projid']."' and DATE(`req_date`)=DATE('".$_POST['date']."')");

mysql_close($con);
?>

Then use ajax to call this page

$.ajax({
  type: "POST",
  url: "Index.php",
  data: { projid: projid , date: date }
}).done(function( msg ) {
  alert( "Data Saved: " + msg );
});
