RE: [PHP] Selecting what's for deletion
Thanks John and Marek for your fast responses. I made the decision to
opt for the "hidden" tag option. Now, I'll show you the part of my code
that hangs when trying to make what I intend it to do.
$query1 = "DELETE * FROM maracat WHERE catid = $catid";
$result1 = mysql_query($query1) or die (mysql_errno());
$query2 = "DELETE * FROM marasubcat WHERE catid = $catid";
$result2 = mysql_query($query2) or die (mysql_errno());
$query3 = "DELETE * FROM maraprod WHERE catid = $catid";
$result3 = mysql_query($query3) or die (mysql_errno());
echo "Accion taken";
echo "Back";
I know that it's very tedious to write 1 query for each action taking
place, but I think this is easier for me to change in the future. Now,
the page gets stuck when reaching this level and doesn't process what I
ordered... Any thoughts? Thanks in advance,

You could use a bunch of forms, if you want to use a button. Since
you're using a while() loop, it wouldn't be a big deal...
While(fetching_from_db)
{
Other data
}
Then the delete button on each row is for it's own form with a hidden
cat_id element that you can use to tell which row to delete.
Even better would be to use checkboxes, so you can delete multiple rows
at one. Name them
And when it's submitted all of the checked boxes will be in
$_POST['delete'], so you can do this:
$delete_ids = implode(",",$_POST['delete']);
$query = "DELETE FROM table WHERE ID IN ($delete_ids)";
Add in your own validation, of course...

Re: [PHP] Selecting what's for deletion
Make the "Delete" button a link with href="delcategory.php?catid=$catid", maybe with additional information so you can redirect the browser back to where it has been (page #, parent category ...)
