[SOLVED] Retrieve the outputted page

[wob_b]

Im try to make a page which does something when its opened with some posted variables, and then saves the page outted as a session, so that if its opened without anything posted it shows the same page it did last time. How can i do this?

[Alex]

I'm not exactly sure what you mean.. Do you mean something like this?

 

<?php
session_start();
if(isset($_POST['var']))
$_SESSION['var'] = $_POST['var'];

if(isset($_SESSION['var']))
echo $_SESSION['var'];

[wob_b]

no. I want to run a line at the end of the php file, which will get the html source code to the page ive just outputted, and then save that as a session.

[Alex]

Oh, I see. Well you can do something like this:

 

<?php
session_start();
ob_start();

echo <<<END
All your page's output here
END;

$_SESSION['var'] = ob_get_contents();
?>

 

$_SESSION['var'] will then include everything that was output on the page.

alex never seen ob_start() after the session_start is that new?

 

 

sorry i get it works with the ob_start();

 

then

 

ob_get_contents to get what in between the two functions.

ob_start() isn't related to session_start(), ob_start() is just to turn output buffering on so that you can catch all the output of the page and set it to a session variable later on through ob_get_contents().

 

Check them out, ob_start(), ob_get_contents()

but , if ob_start() dose not go before the session_start() user's still get there errors.

 

that because they got HTML or wight spaces before session_start() i guess?

It doesn't matter either way because ob_start() doesn't output anything (So you won't get a headers already sent error if you call ob_start() first).

 

So..

 

session_start();
ob_start();

or

ob_start();
session_start();

 

There will be no difference.
