Restricting the file types upload in salesforce chatter

Restricting the file types upload in salesforce chatter


To restrict the file types one option is to write a trigger on "Feeditem".


Developing the Trigger:

Open developer console ,go to "File"---> "New" --->"Apex Trigger".

From the pop-up give the name of the trigger and choose the sObject as "FeedItem" from the dropdown and hit "Submit"

Start Coding !!

//TRIGGER TO RESTRICT FILE TYPES ON CHATTER


trigger restrictFileType on FeedItem (after insert)

{
                  for(FeedItem fi : Trigger.new)

                   {

                                 if(fi.ContentType == 'text')
                                           fi.addError('You are not allowed to upload this kind of file');
                   }

}





You can further enhance the code by adding multiple file types in custom settings and refer it in the trigger instead of hardcoding in the trigger.

Happy Coding !!!!!!

Solving the Logout back button problem through javascript.

In this blog we will see how to solve the logout back button problem, this is a simple solution to handle but its not robust but still works well less number of pages. Here is the JS for <pre> function preventBack(){          window.history.forward();                   }                   setTimeout("preventBack()", 0);          window.onunload=function(){null}; </pre> Here is the Demo Another way of overcoming this would be adding recaptcha to the login form , even though the form gets resubmitted it will fail at captcha as it would be different for every page load.
