Wait, you're using PHP on a JavaScript file (that's what your OP says)? Not gonna work. You're going to have to pass it to a JavaScript function as a parameter like so:

<?php
session_start();

// HTML and stuff

<script type="text/javascript" src="custom.js"></script>
<script type="text/javascript">
passSession("<? echo $_SESSION['session_user_id']; ?>");
</script>

It's hard to say without knowing more about your particular error, but I did notice what seems like a typo in the code you posted:

strActionPage = CurrentPath + "upload_file.php?ation=store&session_user_id=<?php echo $_SESSION['session_user_id']; ?>   "; //the ActionPage's file path

You have ation-store -- did you mean to write action=store?

is a typo because I am translating into English. but is not this. Tks for your reply. – user2112020 Apr 22 '13 at 02:03
in that case, can you edit your OP to give more information about the error and any additional relevant code? – Jonah Apr 22 '13 at 02:41

This is how I might do.

   <script type="text/javascript">

    var user_id=<?php echo $_SESSION['session_user_id']; ?>;

    strActionPage = CurrentPath + "upload_file.php?action=store&session_user_id="+user_id;  

    </script>

There is also a possible mistake. You are using "ation" . Should that be 'action'?
