I haven't done this for 7 tables but I have on occasion deleted from multiple tables successfully. try this and see if it works - also assume this is for 7 tables when I am showing just 3 ( yes, I am lazy to type the extra lines

):

PHP Code:


<?php

// the id/data you want to delete
$del_this_id    =  56;
$col            =  '`Id`';

$sql  =  "DELETE
           `t1`, `t2`, `t3`
         FROM
           `t1`, `t2`, `t3`
         WHERE
             `t1`.$col=`t2`.$col
         AND
             `t2`.$col=`t3`.$col
         AND
             `t3`.$col=$del_this_id";
mysql_query( $sql, $conn );
?>

Please note that this is untested! So your feedback will help others in a similar situation.
