Infinite loop in Facebook Application

Replace this line

$fb_user_id = $facebook->require_login();

$fb_user_id = $facebook->require_login($required_permissions = 'publish_stream');

You may change the permissions as per your requirement.

How To Resize iFrame & Remove Scrollbar From Your iFrame Facebook App?

If you are looking for PHP SDK Click Here to download it.

Code I used to remove the scrollbar from facebook application is this:

function framesetsize(w,h){

var obj = new Object;

obj.width=w;

obj.height=h;

FB.Canvas.setSize(obj);

}

</script>

</div>

</body>

Make sure you set the facebook application setting to AutoResize, to do so follow this instructions:

Login to your Facebook account
Go to Developer panel
Go to your application
Click on Edit Setting
Click on Facebook Integration Tab
Select IFrame size to Auto-resize

Hope this help you to get rid of scrollbars :)

FB.Event.subscribe is not working in IE

The code that I am using is this:

$(document).ready(function(){

FB.Event.subscribe('edge.create', function(response) {

window.location= 'likeApp.php';

});

</script>

The above code works fine in all browsers except IE.

After searching I came to know that we must add the fb-root element just after the body tag (Make sure this tag is right after your body tag):

Hope this helps :)

How to remove top panel Ubuntu

I have got this problem when I tried to put one more panel on the top panel and set it to auto hide, it went into infinite loop and thus my top panel also stopped working.

This is the bug of Ubuntu and if you have the same problem then do the following steps:

Go to terminal, I know your ALT+F2 is not working, try using CTRL+ALT+F3
Find the toplevel directory where all the panel information stores
Code: locate toplevels
Go to toplevel directory
Code: cd /home/username/.gconf/apps/panel/toplevels
Go back one step
Code: cd ..
Rename the toplevel directory
Code: mv toplevels toplevels_old
Log Off the panel and login again
Code: sudo service gdm restart
Now all your panel comes, remove/change the extra panel from top or bottom
Restore the toplevel directory (Go to the directory again)
Code: mv toplevels_old toplevels
Problem is Solved :) :)

Hope this wont take much time to resolve the problem. Let me know in case of any confusion :)

Install xdebug for PHP5 in Ubuntu

This method will work for Ubuntu 8.04 and above
sudo apt-get install php5-xdebug

*********************************************************

This is the alternate method to install Xdebug :)

Here is a mini-howto in how to install the xdebug extension with PHP5 in Ubuntu

This will install xdebug 2.0 (or whatever is latest version in PEAR repository when you try this).

It is assumed you have Apache2 + PHP5 working already.

Code: sudo apt-get install php5-dev php-pear

Now install xdebug thru PECL.
Code: sudo pecl install xdebug

After installing above package it will show you the path of "xdebug.so" file, use it in your further steps.

Then edit php.ini:
Code: sudo gedit /etc/php5/apache2/php.ini

Add the following line:
Code: zend_extension="/usr/lib/php5/20090626+lfs/xdebug.so"

Then restart apache for changes to take effect
Code: sudo /etc/init.d/apache2 restart

Sometimes you also need to edit your "xdebug.ini"
sudo gedit /etc/php5/conf.d/xdebug.ini
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_log="/var/log/xdebug.log"
xdebug.remote_host=localhost
xdebug.remote_port=9000
(Thanks to Chetan Jain for this settings)

**********************************************************

Check phpinfo() to make sure the extension is loaded correctly. The following line should have been appended to the copyright lines:

with Xdebug v2.0.0, Copyright (c) 2002, 2003, 2004, 2005, 2006, 2007, by Derick Rethans

For more information about xdebug configuration and usage, please read the official documentation, found here: http://xdebug.org/docs/
