Question

Am storing a string separated using |, which lists the groups allowed, now my issue is if I delete a group than I am not able to remove the ID from that particular field, for example

allowed_group_id
+---------------+
1332|4545|5646|7986

So for example am deleting the group say no 5646, so how do I alter the scripts and remove that particular group from the allowed_group_id in script table?

Answer 1

I recommend taking the entry, exploding it by “|”, removing the appropriate entry, imploding it back and updating.

$allowedGroupId = '1332|4545|5646|7986';
$parts = explode('|', $allowedGroupId);
if(($key = array_search($deleteGroup, $allowedGroupId)) !== false) {
    unset($allowedGroupId[$key]);
}

$update = " ... "; //update with the new imploded values

Hope it helps
