Loading variables, after they've been parsed?

[intothefray2007]

Hello everyone!

 

Let's start off by saying that I don't have years of experience with PHP programming, though I do understand the language.

 

I have an index.php page that includes the following:

 

---------------------------------------------------------------------

<?php include_once('includes/header.php'); ?>

<?php include_once('includes/menu.php'); ?>

<?php include_once('includes/side.php'); ?>

 

<?php

if (isset($_GET['pg']) && $_GET['pg'] != "") {

$pg = $_GET['pg'];

if (file_exists('pages/'.$pg.'.php')) {

@include ('pages/'.$pg.'.php');

} elseif (!file_exists('pages/'.$pg.'.php')) {

echo 'The page you are requesting does not exist';

}

} else {

@include ('pages/home.php');

}

?>

 

<?php include_once('includes/footer.php'); ?>

---------------------------------------------------------------------

 

After my includes load, the middle part checks which ?id's been sent through the URL so that it loads the appropriate file in my /pages directory (such as about.php). In each of these subpages, I set the "$pagetitle" variable that is called (echo) in header.php.

 

Problem is... I'm calling $pagetitle (in header.php) BEFORE the subpage is called, so the variable gets missed... How do I go about changing the page title AFTER it is originally parsed?

 

Also, I was trying to implement a breadcrumb script in menu.php but I'm not getting anywhere because of this same problem (the breadcrumb script loads before the subpage does).

 

Anyone have a clue on how I can get around this?

 

Thank you!

You can't do much on this as long as you use this system, which is quite ok. What I would do is change the header.php code to display the right title. Let's go for an example:

 

header.php

<?php
$urls = array('home'=>'This is the home page', 'about'=>'Wanna know about me?');
if(isset($_GET['page'])){
     if(array_key_exists($_GET['page'], $urls)){
          echo '<title>' . $urls[$page] . '</title>';
     } else{
          echo '<title>Page does not exist</title>';
     }
} else{
     echo '<title>' . $urls['home'] . '</title>';
}
?>

 

Basically you print the title independent from the included file, but with the proper validation so they match. Hope this gives you the right idea.
