Force reload page when using back button?

Discussion in 'PHP' started by lateuk, Nov 16, 2007.

    Hello,
    I have reciently swapped web hosting companies and therefor i am now using PHP5. One of my pages needs to be reloaded if the back button is used to return to it, i used to use the code:

    header("Cache-Control: no-store, no-cache, must-revalidate");
    header("Cache-Control: post-check=0, pre-check=0", false);

    but this does not seem to work any more.

    Can anyone help?

    Could you please create a phpinfo file and then PM me the URL, you might have missing apache modules that are needed, you old host must have had them but your new host doesn't.

    man i hate it when sites take away the functionality of the back button.

    It's awful design when you need to take away browser functions. Its also a sign that the site is awful, to have to implement code to try and keep a user on it.

    No problem, i completely agree with you, there is nothing worse than going to a page from google and then not being able to use the back button to get back to your Google results.

    You could probs get around it using this cheeky code..?

    
    <?php
    
    session_start();
    if($_SESSION['views'] < 1)
    	{
    		$_SESSION['views'] = 1;
    		?><META HTTP-EQUIV=Refresh CONTENT="0"><?php
    	}
    
    session_destroy();
    
    ?>
    
    PHP:

    That way, each time the page is viewed, it is refreshed. A bit of a nasty work around.

    You could just put the session_destroy() in other pages.

    I dunno - i will try and look for something better.. lol

    AS you always destroy the session, it's the same as writing in the HTML: <META HTTP-EQUIV=Refresh CONTENT="0">

    Simply putting

    session_start();
    PHP:
    on top of my script does the trick for me (PHP Version 5.2.0).

    after back button try to press f5 or refresh, back button still executes
    sesion_start();
    ive tried history +1 on js, just a cheat, that forces the cookies to reload the recent page..
