View Full Version : Add link ID into an Array

11-20-2007, 08:26 PM

I have a page containing 5 links, each link has a different ID number at the end. (Shown in Bold)

http://localhost/Memory.php?action=add&id=1 (http://localhost/Memory.php?action=add&id=1)
http://localhost/Memory.php?action=add&id=2 (http://localhost/Memory.php?action=add&id=2)
http://localhost/Memory.php?action=add&id=3 (http://localhost/Memory.php?action=add&id=3)
http://localhost/Memory.php?action=add&id=4 (http://localhost/Memory.php?action=add&id=4)
http://localhost/Memory.php?action=add&id=5 (http://localhost/Memory.php?action=add&id=5)

Each time a link is clicked, how do I add the id at the end of each link, to an array? But, if array already contains that particular ID, how do I display a message notifying the user e.g. "Already Added!"

Once in the array, how do I output the items in the array to the screen, along with a remove button.

Upon clicking the remove button, how do I delete the appropriate id from the array. The remove link will be in the form of the following:

http://localhost/Memory.php?action=delete&id=1 (http://localhost/Memory.php?action=delete&id=1)
http://localhost/Memory.php?action=delete&id=2 (http://localhost/Memory.php?action=delete&id=2)
http://localhost/Memory.php?action=delete&id=3 (http://localhost/Memory.php?action=delete&id=3)
http://localhost/Memory.php?action=delete&id=4 (http://localhost/Memory.php?action=delete&id=4)
http://localhost/Memory.php?action=delete&id=5 (http://localhost/Memory.php?action=delete&id=5)

Look in the PHP manual for information on Arrays (http://www.php.net/manual/en/ref.array.php). There are plenty of ideas there.

Just a tip, it's not good to name pages with capitals.

There's nothing wrong with it.

It's a recommendation to keep the names all lowercaps because it's easier to not get it wrong.

There's nothing wrong with it but it's not something you should do...?

Sounds like there's one thing wrong with it, if you shouldn't do it. ;)
