DELETE FROM not working deletes wrong row

Posted on 16th Feb 2014 by admin

Hello

I have the following code which i found but it doesnt work properly.. it comes up with a list of the items in the database
e.g.
item 1 - delete
item 2 - delete
item 3 - delete

but when i click delete it deletes a different row and cannot for the life of me figure out why. e.g. if i click delete on item 2 it deletes item 3.


Code: <?php


//If cmd is not hit
if(!isset($cmd))
{
//display all the tbl_testimonies
$result = @mysql_query('SELECT * FROM tbl_testimonies');

if (!$result) {
exit('<p>Error!<br />'.
'Error: ' . mysql_error() . '</p>');
}

while ($r = mysql_fetch_array($result)) {

extract($r);
//grab the tenants_house_name and the tenant_house_id of the enws
$tenants_house_name=$r["tenants_house_name"];//take out the tenants_house_name
$tenant_house_id=$r["tenant_house_id"];//take out the tenant_house_id

echo "<a href='delete.php?cmd=delete&tenant_house_id=$tenant_house_id'>$tenants_house_name - Delete</a>
";

// echo "$tenants_house_name " . "<a href='delete.php?cmd=delete&tenant_house_id=$tenant_house_id'>Delete</a>" ;

}
}
?>

<?php
if($_GET["cmd"]=="delete")

{ $sql = "DELETE FROM tbl_testimonies WHERE tenant_house_id=$tenant_house_id";

$result = mysql_query($sql);
echo "Row deleted!";
}
?>
