Preg_Match source code on current page - Stuck!

[damanic]

Hi there,

I have made this code to detect what section a page is being displayed in and include an apropriate file.

The problem is that if I set the variable $page_check to a file on our server to test it, every thing works as it should.

But then when I place the script in a template file where the $page_check variable is set to $phpself - when loading a page with the script on I get firefox giving me a download box to download the current page file.

So I figure I cant request a page to fopen a url which is the same url the script is on?

So my question is how do I set up this script so it looks at its own source code, does a preg_match to find out what section its in?

<?php
 // the adress of the file to read
$domain = 'http://www.domain.com';
$thispage = $PHP_SELF;
$page_check = "$domain$thispage";

$fp = fopen($page_check, 'r') or die('Unable to open file '.$page_check.' for reading');
 $cont = '';

 while(!feof($fp))
 {
     $buf = trim(fgets($fp, 4096));
     $cont .= $buf;
 }

preg_match('/<a name="sectiontop" id="sectiontop"><A class="breadcrumbs" HREF="(.*?)">/i', $cont, $match);


if ( $match[1] == "books_multimedia.htm")
{
include("/home/public_html/booksnav.php");
}

if ( $match[1] == "products.htm")
{
include("/home/public_html/productsnav.php");
}

if ( $match[1] == "music.htm")
{
include("/home/public_html/musicnav.php");
}

else
{
include("/home/public_html/shopnav.php");
}


?>

Well.. sorry.., but.. this looks a bit sily what you are trying to do..

you try to retrieve the contents of a file, while you are building the file!? That is like tasting what your finished cake tastes like before the cake is in the oven. Impossible.

Why don't you do a match on the $_SERVER['php_self'] ?

Anyway.. it is not clear what you are trying to get out of this, please rephrase your problem (What are you trying to achieve) and I'll have a look again.

I appreciate that it might look silly but its a work around to a problem I have.

Basically it works like this. We have a program that generates a bunch of files from a template.

The template file passes thru cgi so it uses a javascript request to include a php file as php cannot be put into the templates because it will mess up the program that creates the pages.

So the javascript pulls in a php file but the php file wants to know what page it is being pulled into so it can decide which navigation set to display.

So what I need is the php file to look at the source code of the page it is being pulled into and find what section it lies in by looking at the breadcrumbs in the pages html code.

Once it knows the section it can display the right navigation.

Does that help?
