JavaScript browser code to invite all your friends to like facebook page

by viggy — Categories: FOSS, FSMK, FSMK, programming, web — Tags: , , , , , 1 Comment

We have recently announced the FSMK Summer Camp for the year 2014 and also have a facebook page for the same. We wanted to spread the word out about the page by inviting all our friends to ‘like’ the page. FB shows you a list of your friendsĀ  and gives an option to click ‘invite’ for each one of them separately. When you do this, the invited friend gets a notification about the invite and hence more chances of his liking the page.

However this is still cumbersome as it means to invite all your friends which may be around 1000+, you have to click invite so many times.

But you have java script to the rescue. All you need to do is open javascript console on your browser and then execute the following code:


//Note that there is a space after uiButton. This class is the class of the invite button.
var inputs =
document.getElementsByClassName('uiButton _1sm');

for( var i=0; i < inputs.length; i++)
{
inputs[i].click();
}


To find out how to run javascript code in Firefox, check the following link.

If sadly you are not using the best and fastest browser, Firefox, then you can of course find similar tutorials for other browsers or realize it is time to switch to Firefox as Firefox29 is just released and its AWESOME!!!

P.S. The code was shared to me by Karthik Nayak from BMSIT GLUG.

Fatal error : Call to undefined function: ldap_connect()

by viggy — Categories: drupal, tech, web — Tags: , , , , Leave a comment

I got this error when I was trying to get my drupal installation authenticate using the local ldap directory. Initially, I had thought that I was getting error because of my ldap settings. Then I enabled error reporting on my site, that is when this error was displayed to me.

This error is caused, I suppose due to the missing package php5-ldap in the system. After I installed this package using apt-get and restarted apache2, LDAP authentication wroked fine.

The White Screen of Death (Completely Blank Page) in drupal

by viggy — Categories: drupal, tech, web — Tags: , , , , Leave a comment

Occasionally a site user or developer will navigate to a page and suddenly the page content disappears, and is completely blank. No content. No errors. Nothing. This often, but not always, happens after updating a module, theme, or Drupal core. This is what is referred to by most members of the Drupal community as the White Screen of Death or WSOD. There are several reasons why this might occur, and therefore several possible solutions to the issue.

For how to solve this problem, look here.

How to enable error reporting in drupal

Enable Error Reporting

Although it may be turned off on commercial hosts and production sites (for good reason, so that users do not see the errors), these errors are one of your best tools for troubleshooting. To enable error reporting, temporarily edit your index.php file (normally located in your root directory) directly after the first opening PHP tag (do not edit the actual file info!) to add the following:

<?php

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

// $Id: index.php,v 1.94 2007/12/26...

You will now be able to see any errors that are occurring directly on the screen. Memory problems may still not be displayed, but it’s the first step in a process of elimination.

If you are using a multi-site setup and only want errors to appear for one site, then check the name of the host first as in:
