Script not working?

[intothefray2007]

Someone gave me a hand with a way to load breadcrumbs after the header has loaded, but I'm having trouble getting this to work. Can anyone take a look?

 

I'm using the following structure:

 

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

index.php

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

<?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 requested does not exist';

}

} else {

    @include ('pages/home.php');

}

?>

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

 

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

menu.php

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

<?php

$breadcrumb = array('home'=>'Home', 'about'=>'About Us');

if(isset($_GET['pg'])){

    if(array_key_exists($_GET['pg'], $breadcrumb)){

          echo $breadcrumb[$pg];

    } else{

          echo 'This breadcrumb does not exist';

    }

} else{

    echo $breadcrumb['home'];

}

?>

 

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

A sample URL would be http://www.mywebsite.com/?pg=about

 

The original script in the index.php file checks the variable $pg and includes the appropriate PHP file from the /pages directory.

The breadcrumb script in menu.php also checks the $pg variable and sets the breadcrumb accordingly.

 

Sounds good.... but for some reason it is not printing out anything at all ($breadcrumb), UNLESS I load the URL without a ?pg= value, in which case I get the default value ('home').

 

Anyone have any ideas? Thanks!

Okay firstly, just as a heads up you don't need...

 

<?php include_once('includes/header.php'); ?>
<?php include_once('includes/menu.php'); ?>
<?php include_once('includes/side.php'); ?>
<?php
if (isset($.......

 

you can just use...

 

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

if (isset($...........

 

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

 

Try adding some static text to the echo to see if it it's something to do with setting up the array.. like...

 

if(array_key_exists($_GET['pg'], $breadcrumb)){
     echo 'Breadcrumbs: ' . $breadcrumb[$pg];
} else{
     echo 'This breadcrumb does not exist';
}

Good suggestion, it did output the text so there is obviously something wrong with the array's output... but why?

Turned on error reporting and got the following:

 

Notice: Undefined variable: pg in /home/blackbir/public_html/test/v3/includes/menu.php on line 47

Notice: Undefined index: in /home/blackbir/public_html/test/v3/includes/menu.php on line 47

 

Not quite sure how to deal with that...?
