Variable Scope problem

bostonmacosx

  IAF_display_js(); 
$uploader = new FlashUploader('uploader', '***************s/inaflash/uploader','**********tions/inaflash/upload-debug.php');
$uploader->pass_var('whicharea','$_SESSION[temp_name]');
$uploader->display();

I have the above code and when the pass_var method is run the second parameter is always blank. I'm not sure why I have session_start() called at the top of the page and other things on the page which require SEssions.

Thanks

If you use the value of that $_SESSION variable
then yo need session_start()

I do not know if you should pass the value or, as you have, the name of that session variable.

If it is the value that should be passed
then I should try this:

<?php
session_start();

IAF_display_js();
$uploader = new FlashUploader('uploader', '***************s/inaflash/uploader','**********tions/inaflash/upload-debug.php');

$uploader->pass_var('whicharea', $_SESSION['temp_name']);
$uploader->display(); 
?>

as I mentioned in the original post I do have session_start() at the top of the page.

Good.
Then you can try these lines of my code

<?php

IAF_display_js();
$uploader = new FlashUploader('uploader', '***************s/inaflash/uploader','**********tions/inaflash/upload-debug.php');

$uploader->pass_var('whicharea', $_SESSION['temp_name']);
$uploader->display();
?>

One problem I see is here:

$uploader->pass_var('whicharea','$_SESSION[temp_name]');

For the value of the second parameter of pass_var(), you've passed a string that contains a dollar sign, an underscore, the word 'SESSION', and "temp_name" surrounded by square brackets.

In halojoy's code, however, the value of the variable $_SESSION['temp_name'] is being passed. The difference is that you surroudned the variable with single quotes, and variable parsing is only done in double-quoted strings (but since you're only using the value of a variable, it's pointless to add any quotes at all).
