Dynamic <title> according to page URL

[subho]

Hi All
I am new to php and trying to learn it.

I am developing a website using <?php include(''); ?> function. Entire website is divided into 5 templates such as "meta.php","header.php","navigation.php","righ t-menu.php", "footer.php". Till now <title>, <meta keywords>, <meta description> are static and place manually. I want these information to be dynamic from a .xml file stored inside server.

I am already able to fetch <meta keywords> and <meta descriptions> using php "simplexml_load_file". I want <title> to appear according to page URL/page name.I have few sets of <title> for each individual page inside .xml file. As an instance,for http://www.examplesite.com/vocal-science.php I have "Vocal Science" string.

Is it possible to fetch individual keywords from .xml file according to page URL? This is the solution I am looking for desperately. Any example or any tutorial is appreciable.

Thanks in advance

The simplexml_load_file documentation should include everything you need - there are numerous examples in the comments.

If you are not familiar with the PHP $_SESSION superglobal you will likely find that $_SERVER['REQUEST_URI'] is variable you have been looking for to map your XML data to individual URI's on your site (though, in the example below, my implementation uses the $_GET['page'] variable with a mod_rewrite directive instead).

Your solution will ultimately look something like this:

XML File:

<?xml version="1.0" encoding="utf-8" ?>
<pages>
	<page>
		<uri>/</uri>
		<title>Homepage</title>
		<content>This is the homepage.</content>
	</page>
	<page>
		<uri>/vocal-science.php</uri>
		<title>Vocal Science</title>
		<content>This is the page about vocal science.</content>
	</page>
</pages>

index.php Code:

PHP Code:

<?php

define( 'PATH_INCLUDES', '/path/to/your/includes/' );
define( 'PATH_SITEFILE', '/path/to/your/xml/file/' );

$page = array();

if ( file_exists( PATH_SITEFILE ) ) {
    $xml = simplexml_load_file( PATH_SITEFILE );
    $count_pages = count( $xml->page );
    if ( $count_pages ) {
        for( $i = 0; $i < $count_pages; $i++ ) {
            $page = $xml->page[$i];
            if ( $page['uri'] == $_GET['page'] ) {
                $page_display['title'] = $page['title'];
                $page_display['content'] = $page['content'];
            }
        }
    } else {
        $page_display['title'] = 'Error - No page information available';
        $page_display['content'] = 'Site file found at ' . PATH_SITEFILE . ' contained no pages';
    }
} else {
    $page_display['title'] = 'Error - Unable to load site file';
    $page_display['content'] = 'Site file not found at ' . PATH_SITEFILE;
}

// Include template file(s) which echo $page_display variables
require_once( PATH_INCLUDES . 'template.inc.php' );

?>

mod_rewrite Directives:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) /index.php?file=/$1 [L,QSA]

... that will probably work.

I would ask the same before telling the guy how to do it. It is rather easy to accomplish, but let's see his need for it first.

subho has 85 posts and he has been a member here since 2005... I'd give him the benefit of the doubt on this one.

Anyone interested in copying a site's content has many, many options (almost all of which are more convenient than coding up a PHP script to read an XML file) - and anyone who has been a user on this site for four years should know better than to serve up duplicate content

[wige]

While I agree it is probable that he is not copying another site, I am just suspicious by nature I suppose. However, if the content that will be used as the title and keywords is being stored locally, there might be more efficient ways of doing this - such as reading the information from a database, unless he is pulling a file from another website, where his options become more limited.

import xml to mysql, then select * from tablename where url like '%specific urlpart%' then echo culled data where applicable.
