Using something like:

I want to echo out $stuff.

What's the proper syntax?

Thanks!

Hi, young Jedi, you're gravely mistaken on a thing or two ....

Gosh, I botched that quote really badly, didn't I :rolleyes:

"onclick" is a Javascript event handler under the applet, area, body, button, checkbox, document fileupload, (and several other) objects.

So, you'll need a Javascript solution...you might get that here at PHPBuilder, but you'd be possibly better off at javascriptworld.com, or devshed, etc. etc......

Indeed, PHP is server side, and can't do things like that without a page submit.

I'm using Layers -- and have what I consider a scoping problem.

If the PHP on Layer1 sets a variable "($fred="AAAAAAAA"😉, it's apprenantly not available in Layer2 - if I set $fred outside the layer -- apparently it's available???????

How do I set a variable in Layer1 and then access it in Layer2?

This is very frustrating!

Please post some code---just to clarify if nothing else. It sounds like you are using a PHP if to control whether you display layer1 or layer2--and within that if, you set $fred=something--and yet you want it to display in layer 2 as well. You may be able to just pull the $fred set out of the if (if it is going to be the same regardless of which layer is displayed.--Or it could very well be that I am really confused about what you really want to do...🙂

Here's the test code I'm working with. The hide/show/snap layers is frpm PVII.

$arr_tablenames[] = '';

for ($i=0; $i < $num_tables; $i++) {
