Problem

I need to override the email validation service so that we can use a custom validation .

Solution

There are a few step to follow for this solution. Find the service that provides the validation service

1. Find the service and the file 
   • There are a couple of ways to find the service
     1. GOTO https://api.drupal.org/api/drupal/services and just serach for it
     2. Use Drupal console 

        drupal debug:container | grep email

Problem:

I need to redirect a form to a specific URL on submit

Solution

1. Add a custom submit on hook_form_alter();

   • Use either of the lines below

PROBLEM: 

I needed to add a NOT IN condition with a nested query for the WHERE condition. The usual method wont work

 

$view->query->where[1]['conditions'][] = array(
            ['field'] => 'groups_group_membership.type'
            ['value'] => array
                (
                    [0] => 'SELECT_QUERY_HERE'
                  
                )

            ['operator'] => IN
        );

SOLUTION :

The way that works
