Deleting multiple rows from a mysql db with php and checkboxes

Asked by Simon336697 in PHP Scripting Language

Hi guys.

Guys im going through this code below and having some issues actually deleting records by clicking on the checkboxes.
The code works in terms of displaying the records from the mysql database, and I can delete records by mysql query browser, but not through using the code below.

Basically this code is meant for you to click on multiple or a single checkbox, click on the delete button, and that record is deleted from the database.

I think the problem lies somewhere in:

if($delete){
      for($i=0;$i<$count;$i++){
            $del_id = $checkbox[$i];
            $sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
            $result = mysql_query($sql);
      }

// if successful redirect to delete_multiple.php
      if($result){
            echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">";
      }
}
mysql_close();
?>

Any help greatly appreciated.
