Problem with PHP and Frames

[Anon]

Hi, I've got a problem with frames and php:
I want to create a frameset in php that passes through external variables.

In the menu page (in frame A) 3 variables are defined which are passed through to another page (in frame 😎. Instead of opening a standard php-page I want to open another frameset (main-index.php) in frame B. The important thing is that the 3 variables have to be passed through to the pages that main-index.php contains, because they determine the content of these pages. I have tried some things myself, but sadly enough I got no results. I can give you this bits of code:

the menupage submits the following to frame B:

main-index.php?category=A&type=B&name=C

main-index.php contains the following code:

$frame1 = "<FRAME src=\"title.php?category=".$category."&type=".$type."&name=".$name."\" name=\"title\">";

$frame2 = "<FRAME src=\"main.php?category=".$category."&type=".$type."&name=".$name."\" name=\"main\">";

echo '<FRAMESET>';
echo $$frame1;
echo $$frame2;
echo '</FRAMESET>';

I hope someone can help me. Thanks in advance for your replies, Michiel

Why double "$"? frame1 and frame2 are not variable variables - they're plain strings.

whats a variable variable?

I'm currently doing the same thing in a survey I'm putting together, and got it to work by simply embedding the php variable references within the HTML (sometimes easier for small pages such as framesets).

I would be interested, however to know if there was an alternative way of passing php variables into frames (i.e. not via the URL)?

cheers

Variable variable is the one beginning with two "$". For example:

$x = "a";

Then, $$x is exactly the same as $a. Just try echoing $frame1 and $frame2 (only one "$" with each variable).

As for alternative way, this one is usually the best. Alternative might be cookies, but they are unreliable and (in your case at least) unneeded.
