Yes you can do this, but you will write simple plugin based on our Skeleton plugin.

here a plugin and documentation of our Triggers https://www.easy-profile.com/docs/44-triggers.html

You can do something like this:
- Download, install, and enable our Skeleton plugin
- Go on file /plugins/jsn/skeleton/skeleton.php
- delete examples functions triggerFieldAvatarUpdate and triggerProfileUpdate
- write a function like this

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

    // Recognize last customer id

    $query="SELECT customer_id FROM #__jsn_users ORDER BY customer_id DESC LIMIT 1"

    $db=JFactory::getDbo();

    $db->setQuery($query);

    $last_customer_id=$db->loadResult();

    // Increment customer id value

    $new_customer_id=$last_customer_id+1;

    // Fill the data variable to store it in DB

    $data['customer_id']=$new_customer_id;

}

NOTE: this code is not tested and not supported and require minimum PHP knowledge

Hi a question, in these case, the variable is declared in the easy user component or in the DB joomla in users table manually?

If you say about "customer_id" column, you can add this as field from Easy Profile component. When you create a field EP create table column with same name of alias field

Hi per example i put the code in skeleton (the field in the component is Numero de Casillero (Alias: num_casillero))

triggerProfileUpdate($user,&$data,$changed,$isNew){
// Recognize last customer id
$query="SELECT num_casillero FROM #__jsn_users ORDER BY num_casillero DESC LIMIT 1"
$db=JFactory::getDbo();
$db->setQuery($query);
$last_casillero=$db->loadResult();
// Increment customer id value
$new_casillero=$last_casillero+1;
// Fill the data variable to store it in DB
$data['num_casillero']=$new_casillero;
}

I attached an image of the configuration of the field on easy profile, i tested creating a new customer but the data show, the field is a number, i don't know if need to be a string or something like that

I created a new user (the second new) but i see that doesnt show anything, and in the DB i see the value in null in jnusers

Works great thanks, I have my last question, i want to have a tracking systems or tab, with 4 parameters, i can add a row or the customers, you can do that? I know that is not included on the module, is an extra work, can you?

Sorry but we do not work as freelance...but please explain me with more details, maybe it's simple and we can help you to find correct way.

Ok per example we want to have a group field
My Packages (tab) when customer press the tab show the packages that has
Values: Description, Courrier, Tracking Number, State, Invoice

And show the list that has, the old and new, maybe if has a lot use pagination per example, the thing is that we want to add packages, and permit to the customer add packages (pre alert), is posible ? Thanks

Hi I don't receive any answer since august 13, any advise? Regards

Hi,
sorry for late reply,
half of our staff is in holiday

So, your request is too complex for our support, but we are available to create integrations with other components. so if you can find a component that will handle these "Packages", we can carry out the integration.
