sessions + refreshing

AmadoR

Hello.

I have a problem and I was wondering if some kind soul could help me.

I'm making a site that only registered users can access, and I use sessions to control it.

Logged in users can upload diferent kinds of files from certain page that is opened by a parent window in a pop-up window. The parent window shows some data that is retrived from a MySQL database and has a session_start() at the top to validate some control variables.

The pop-up window uploads the file correctly and after that some records in the database are updated, data that is also shown in the parent window.

In order to refresh the data just updated, I call a javascript function to do a submit in the parent window and to close the pop-up window.

Here's the problem: The parent window's data is not refreshed by the submit unless I take away the session_start() statement from the code or unless I delete the cache and temporary files and reload the page manually.

I added a submit button in the parent window and after the pop-up window is closed, I press the button and in some cases the page is refreshed in others it is not. I don't believe the button is the right solution.

I'm getting frustrated. Can anybody, PLEASE, help me? I need to refresh the page with the session_start() statement included on the top of my code.

After three days, I finally understood what was wrong. I was the session.chache_limiter which was supposed to be nocache on the php.ini.

I dunno anything about that session.chache_limiter, but did you try this:

You open a pop-up page from your parent page. This parent page is your main page that controls users and if someone doesn't have a session, then he/she can not view your page. So, when you open your pop-up window, you have a form in it, that ppl can upload stuff, right? So, why don't you write the name of your parent page as the action of your form and then write a simple window.close() function in the onsubmit part of the form? So, the new data is sent to your parent page, and the current pop up page is closed by that little JS function.

I don't think that you are writing into the database from a different page than your parent page, because by submitting the form in the pop-up page, that new page will be opened. And I also think that relying on JS functions for a PHP program isn't that good! You know, if JS is disabled somehow, then your script doesn't work! It's JS dependent.
