SimpleXML addChild won't accept $_SERVER['REQUEST_URI']

[aidangig]

Hey,

 

I want to use $_SERVER['REQUEST_URI'] in my addChild since I have a lot of get variables I also need to add to the 'url' node. when I use :

$entry->addChild('url', 'http://boston.lit.life' . $_SERVER['REQUEST_URI']);

It just duplicates this code as the 'url' :

$entry->addChild('title', chop($_GET['city'] .' - '. $_GET['title']) .' for '. $_GET['price'] .' from @'. $dir_auth1); 

as the 'URL' node or the added child.

Inside of the .xml file it adds this : 

<link><title>South Boston - The good stuff for $15 from @aidan</title><url/></link><link><title>South Boston - The good stuff for $15 from @aidan</title><url/></link>

I want to use $_SERVER['REQUEST_URI'] for 'url' to add the entire URL INCLUDING $_GET variables inside of the xml file it is writing to. Not just duplicate the title instead.

<?php
$headers = 'links.xml';
$xml = simplexml_load_file('/home/thecookie12/public_html/links.xml');


$entry = $xml->addChild('link');
$entry->addChild('title', chop($_GET['city'] .' - '. $_GET['title']) .' for '. $_GET['price'] .' from @'. $dir_auth1);
$entry->addChild('url', 'http://boston.lit.life' . $_SERVER['REQUEST_URI']);






$xml->asXML('/home/thecookie12/public_html/links.xml')




?>

If anyone  has an idea of why this is not working or there is a work around please let me know.

What does not working mean?  Have you echo'ed out the resulting string you create with this logic?

 

Is using $_GET your best option for this exercise?

Thank you for the quick response!

I said not working because it doesn't add the entire URL with get parameters.

URL without get parameters inside of the child 'url' will not function properly with what I am trying to do.

Yes, currently $_GET is my best method. 

I believe more so that it is the $_SERVER['REQUEST_URI'] is the main issue.

I tried using the strval() function

It does a very basic function to convert to string. 

I tried using that as well. 

Nothing is really working as of now.

addChild has an annoying quirk where you have to encode ampersands. Just ampersands. It issues a warning, and if you're not seeing it then you don't have your environment properly set up for development.

 

As an alternative you can not specify the value in the method call and instead assign it manually.

$entry->addChild('title')->value = chop($_GET['city'] .' - '. $_GET['title']) .' for '. $_GET['price'] .' from @'. $dir_auth1);

Thank you requinix!

This was perfect as it set on the right foot. 

I wrote my own code by this definitely helped me
