PHP includes & iFRAME

[rIGO]

hey guys,

im trying to find an alternative solution to iFRAME as most browers do not like iFRAME.

now i was trying to use PHP and tried the following...

<?php
      if ($show == "") {
        include ("main.php");
      } else {
         include ("$show.php");
      }
?>

now in theory if i do call index.php?show=news i should be calling news.php in the index page right?? for some reason it calling the news page seperately and not in the index page.

any ideas?

Try

<?php
if ($_GET['show'] == "" ) {
include 'main.php';
} else {
include $show.'.php';
}
?>

<?php
$show = addslashes( strip_tags( $_GET['show'] ) );

if (empty($show))
{
    include('main.php');
}
else
{
    include($show . '.php');
}
?>

ok now it works.... but i have another problem... in news i want restricted access so i have created a session. obviously when i call index.php?show=news this error comes up

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

any ideas...how i can arrange it?

You have to put session_start() before any info is sent to the browser. IE

<?php
session_start();
$show = addslashes( strip_tags( $_GET['show'] ) );

if (empty($show))
{
include('main.php');
}
else
{
include($show . '.php');
}
?>

}

ok...but that starts a session even when im in main.php. is it wise to add a session and i do not use it? i only need the session when $show=news.

It doesn't matter when you start the session. Also, unless you use output buffering you don't have choice because, as The New Guy says, you cannot start a session after any characters have been sent to the client's browser.

ok...i got news.php working with that... but now i get the following error for main.php (main.php does not need session_start):

session_start() [function.session-start]: Cannot send session cookie - headers already sent

[rIGO]

sorry news.php doesnt work with this method... the error comes again.

session_start() must be specified somewhere else...i guess...before the actual headers. right?

In a nutshell, session_start() should be specified before any headers are sent to the client's browser. Stick it at the top of the page.
