PHP $_REQUEST['URL'] and $_REQUEST['title'] not working

Firstly, I'm suspecting that "URL" and "title" are fields on the submitting form?

Secondly, $_REQUEST is defined as "An associative array consisting of the contents of $_GET, $_POST, and $_COOKIE."

Maybe try using $_POST or $_GET depending on the method of the form. For example, if your form is posted, try $_POST["URL"] and $_POST["title"].

Alternatively, you can always use server variables to find out the URL requested, it's referring URL, and info about the requesting browser, e.g.:

$HTTP SERVER_VARS['HTTPREFERER'];
$HTTP SERVER_VARS['HTTP_USERAGENT'];
$HTTP SERVER_VARS['REMOTEADDR'];
$HTTP SERVER_VARS['SCRIPTURI']

It appears that using $_SERVER is more modern and more functional than $HTTP SERVERVARS. I've switched one of my pages and the functionality is the same.

More info on all of this here: http://us2.php.net/manual/en/reserved.variables.php

Message was edited by jaydisc to include $_SERVER info

Firstly, at least in your post, you're misspelling HTTP_REFERER (you spelled it HTTP_REFERRER)

Secondly, remember the HTTP_REFERER is only populated if you clicked a link to get to that page. It will not be populated if you just point your browser to a page echoing it.

I thought I would be able to retrieve the same information by using something like

<?php
$referrer = $_SERVER['HTTP_REFERRER'];
echo "referrer is: $referrer \n";
?>

but alas, no referrer gets output... other elements of $_SERVER array can get output, such as HTTP_USER_AGENT, but not the HTTP_REFERRER.

So to see which elements were populated by default, I saved the following script as show_elements.php

<?php
print_r($_SERVER);
?>

and when I point my browser to this file, it yields:


Array ( [DOCUMENT_ROOT] => /Library/WebServer/Documents/my.example.com [HTTP_ACCEPT] => text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8 ,image/png,*/*;q=0.5 [HTTP_ACCEPT_CHARSET] => ISO-8859-1,utf-8;q=0.7,*;q=0.7 [HTTP_ACCEPT_ENCODING] => gzip,deflate [HTTP_ACCEPT_LANGUAGE] => en-us,en;q=0.5 [HTTP_CONNECTION] => keep-alive [HTTP_HOST] => my.example.com [HTTP_KEEP_ALIVE] => 300 [HTTP_USER_AGENT] => Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11 [PATH] => /bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/System/Library/CoreServices [REMOTE_ADDR] => ##.##.##.###(my.remote.ip) [REMOTE_PORT] => 54136 [SCRIPT_FILENAME] => /Library/WebServer/Documents/my.example.com/show_elements.php [SCRIPT_URI] => http://my.example.com/show_elements.php [SCRIPT_URL] => /show_elements.php [SERVER_ADDR] => 192.168.2.224 [SERVER_ADMIN] => admin@example.com [SERVER_NAME] => my.example.com [SERVER_PORT] => 80 [SERVER_SIGNATURE] =>

The php manual says that the entries of the $_SERVER array are set by the web server, so, the question, in my mind, is how to get Apache to populate the HTTP_REFERRER element of the $_SERVER array?

I would find this useful for tracking effectiveness of link exchanges, paid advertising, and much more, and would love it if this topic gets resolved...

sorry... variable names don't work when they are mispelled...

the $ SERVER['HTTPREFERER'] works great. I made an arbitrary file called origin.html that just contained a link to a php script duely named referer.php, which was just

<?php
$referer=$ SERVER['HTTPREFERER'];
echo "referring page was: $referer\n";
?>

and when I pointed browser to the origin page and clicked on link to the referer.php script, the result was

referring page was: http://my.example.com/orgin.html

So it works.


Thanks jaydisk.
