facebook like button (current page)

I'm looking for a php or other language script that can get the current page link (address bar)which could be inserted into the facebook LIKE code :

<iframe src="http://www.facebook.com/plugins/like.php?href=[B][COLOR="Red"]http://example.com[/COLOR][/B]%2Fpage%2Fto%2Flike&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true"></iframe> 

Code (markup):

Because its an iframe, I'm lost on how to do this ?

EDIT:

I found it:

<iframe src="http://www.facebook.com/widgets/like.php?href=<?= "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; ?>" scrolling="no" frameborder="0" style="border:none; width: 450px; height: 80px;"></iframe>

PHP:

Well the above does get the full url, however facebook will only store the domain_name and the ?first=variable

 

urlencode() the request uri.

 

I understand what your saying, but the js code on facebook rewrites the url so it doesn't matter what way you send it in, ie: view the iframe source code here on dp's facebook like button

My solution was to write a .htaccess redirect

 

if your url has an & in it, it will be processed as another variable instead of part of the URL iirc, that's why I said urlencode

 

The snippet to get the URL is

<?php
$url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $url;
?>

PHP:

 

i doesn't work with me

 

<iframe src="http://www.facebook.com/widgets/like.php?href=<?=urlencode("http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']); ?>" scrolling="no" frameborder="0" style="border:none; width: 450px; height: 80px;"></iframe>

PHP:

 

this is the exactly what you are looking about. i have tested this and it worked well. Thanks @K1llswitch

 

No problamo.

 

Hi K1llswitch,
I need a standard size button not the ( width: 450px; height: 80px; ). It will be a standard size with like count 1, 2, 3, 4.... Kindly suggest..
Thanks

 

like button uses the id of the facebook page. For G+ you can +1'd any page, on facebook you can like only the facebook page

 

This is not working for me, I can see that the page extended so the code is red, but no button appear.
