</tr></table>
</form>

etc

i just get a blank page, but ht eaddress is right

I can not see any link or formfield with the name "action" in the HTML part.

if (isset($action) && $action == 'folder') {

So, where did you define the variable $action?

arrrr.... i just used a link.. : ie
print '<center>
<a href="admin.php?action=add">Add a Photo</a> :
<a href="admin.php?action=edit">Move or Edit a photo</a> :
<a href="admin.php?action=folder">Create or remove a folder</a>
</center>';

then if teh varible has been filled in, ie the link clicked, then it works.. but it don't

You have read the documantation from my link above?

<a href="admin.php?action=add">Add a Photo</a>

A click on a link is a GET-request. So you can refere this variable as $_GET['action'].

ok, but how do i define it? i feeling realy retarded at the mo...

how do i set it equal to part of an address?

do i need to have $_GET['action'] = $action?

or go:
if ($_GET($action) && $action == 'folder') {
?

ok, but how do i define it?

You must define nothing...:
1) External GET-variables will not automatically import to the global scope. So you have no $action, but you have $_GET['action'].

Ok, you can assign a external variable to a global one with

Code: Select all

$action = $_GET['action'];

and then work with $action in your code.

2) $_GET is a array like every other array too and you can make the same things with it.

Code: Select all

if (isset($action) && $action == 'folder') {

This should be:

Code: Select all

if (isset($_GET['action']) && ($_GET['action'] == 'folder')) {

You see, no need to import the external variable, you can work diretly with it in this simple case.

ok, thanks for your help, i'll have a go now

[edit] god like... it works now.. thanks for all your help, and paitence...
