Transferring variables between pages

[pistonhead]

Hi

I was wondering- how can I transfer fixed variables (which are declared in the code, no input from user) between pages, without using the URL (preferably using buttons)?

 

Any help would be greatly appreciated.

 

Thanks

$_POST

$_POST

 

That means I'd have to include a form, but the variables have nothing to do with the user. I require no input from them.

i assume there will be some clicking somewhere on the page, as you said you'd like to pass variables based on a user clicking a button.

 

<form name="passing vars" method="post">

<input type="hidden" value="variable" />

<input type="hidden" value="variable2" />

<input type="button" value="Continue on without filling out any of the HIDDEN fields cause im pr0" />

</form>

 

You are correct. It requires a form. but not one that the user can fill out.

use session variables.  just makes sure you have session_start(); at the top of each page else the session variables won't work

 

Page1:

<?php

session_start();

$_SESSION['AnswerToLife'] = 42;

?>

 

Page2:

<?php

session_start();

echo $_SESSION['AnswerToLife']; //it would output '42'

?>

Is there any way I could transfer the variables using clickable pictures?

i.e:

<a href="diagram.php"><img align="left"border="0"
        src="globe/200px-Europe_(orthographic_projection).svg.png" 
        width="150" alt="Europe" height="150" alt="Europe"/></a>

only way I can think of doing it from clickable pictures is to do it through a url variable, such as <a href="diagram.php?picture=Europe"><img></a>

Aah, I'm using a specific API key for the linked page. Guess I could send the variables via the URL, and have a conditional statement within the linked page, which selects a certain API key based on the variables passed through.

 

Thanks a lot for your help.
