Easy Profile - Joomla Extension

Hi,
this is not possible with a simple way, I think that the best way to do this without hack the code of Easy Profile is to use another field to order:

1) Create a text field type with alias "birthdate_order" (no available in profile, edit profile, registration pages, basically it is a system field useful only for the order)
2) Create a plugin that store in this field only the month and the day
- Download (at the end of docs page at http://docs.easy-profile.com/index.php/article/triggers ), install and enable (Extensions->Plugins) skeleton plugin
- Open the edit the file at /plugins/jsn/skeleton/skeleton.php
- Replace entire code with this

<?php



defined('_JEXEC') or die;



class PlgJsnSkeleton extends JPlugin

{

	public function triggerProfileUpdate($user, &$data, $changed, $isNew)

	{

		if( !empty( $data[ 'birthday' ] ) ){

                    $data[ 'birthdate_order' ] = substr( $data[ 'birthday' ] , 5 ); /* date field have a format like 1983-03-28, so we need to remove the first 5 characters to have something like 03-28 */

                }

	}

}

3) set "birthdate_order" as first order field

This code will fill the field "birthdate_order" with only month and day when you register or update some user, so for existing users you need to fill "birthdate_order" with a simple SQL like:

UPDATE #__jsn_users SET birthdate_order = SUBSTRING(birthday, 6)

NOTES:
- in the PHP substr function the first character position is 0, so with substr( $data[ 'birthday' ] , 5 ) we remove the first 5 chars (YYYY-), the new string start from 5th char
- in the MYSQL SUBSTRING function the first character position is 1, so with SUBSTRING(birthday, 6) we remove the first 5 chars (YYYY-), the new string start from 6th char
- This code is not tested, I wrote this quickly therefore I recommend you to do some tests

Hi, and thanks for the code, very much appreciated
I can see how that will work.
I have a question related to this.
We already use the Skeleton.php code for our Social Network.
I have attached a zip file with the code we use.
Is there anything I should be aware of when integrating your code with the existing code in Skeleton?

Kind regards
David

No, you can append the code below or above your existing code in function triggerProfileUpdate, for example:

defined('_JEXEC') or die;



class PlgJsnSkeleton extends JPlugin

{

    public function triggerProfileUpdate($user,&$data,$changed,$isNew){ 

        if( !empty( $data[ 'birthday' ] ) ){

            $data[ 'birthdate_order' ] = substr( $data[ 'birthday' ] , 5 ); /* date field have a format like 1983-03-28, so we need to remove the first 5 characters to have something like 03-28 */

        }

        /* HERE YOUR EXISTING CODE */

    }

}

That's great... Thank you so much for quick response, very much appreciated.
I will go away and test it and come back to you.
Kind regards
David
