User registration by email with autopassword and autologin

Hello,
I guess this is not possible to do with chronoforms, but asking doesn't hurt🙂

I need a simple form with only email input field, this should create a new user
using as username the first part of the email (before @), generate automatically a random password, and autologin the user after submission.

An email should then be sent to the user with his account details.

I know that there a couple of extensions already able to do this, but I was looking for a more flexible solution using chronoforms.

Thank you,
Nic

I guess the only thing that is not possible with the registration action:
using as name and username the first part of the email (before @)

Hi oloccina,

You can do that if you need to. Add a Custom Code action before the Joomla! Registration and use PHP to remove the email domain and add the result to a new form variable. Something like this:

<?php
$user_name = explode('@', $form->data['email']);
$form->data['user_name'] = $user_name[0];
?>

Thanks!
but what do I insert int he "username" field in the "joomla registration" action?

I just inserted the php code you suggested ina custom code before the action,
and filled in only the "email" field in the action,

th is my form code right now

<div class="form-group gcore-form-row" id="form-row-email"><label for="email" class="control-label gcore-label-left">E-mail</label>
<div class="gcore-input gcore-display-table" id="fin-email"><input name="email" id="email" value="" placeholder="la tua email" class="validate['required','email'] form-control A" title="" style="" data-inputmask="" data-load-state="" data-tooltip="" type="text" /></div></div><div class="form-group gcore-form-row" id="form-row-button2"><div class="gcore-input gcore-display-table" id="fin-button2"><input name="button2" id="button2" type="submit" value="Accedi al corso!" class="btn btn-default form-control A" style="" data-load-state="" /></div></div>

this is my setup attached

Ok,
got it working,

it register correctl a new user but it still uses
the full email address for both name and username,
it doesn't only use th epart before @

I attach this form for your reference

what I didi to get it working was just fill in the name and username password
using the "email" value

sorry, I am not very tech savvy :-(

Hi oloccina,

In the Registration action you need to put user_name in the Username and Name boxes.

Bob

great, that didi the trick!

another issue that cime to my mind is that many people register using info@...
as their email address, thus the generated usernames would be all the same,
could you tell me where can I find another code snippet that can check if the username
is already existing and in case add numbers after it, like info1, info2, info3 ?

Thank you!

Hi oloccina,

Hmmm . . . there are a couple of ways to do this, I think I'd try something like this:

<?php
$user_name = explode('@', $form->data['email']);
$user_name = $user_name[0];
$db = \JFactory::getDBO();
$query = "
    SELECT `username`
        FROM `#__users`
        WHERE `username` LIKE '{$user_name}%' ;
";
$db->setQuery($query);
$usernames = $db->loadColumn();
$temp = $user_name;
if ( count($usernames) > 0 ) {
  while ( in_array( $temp, $usernames ) ) {
    $temp = $user_name.'_'.rand(1111, 9999);
  }
}
$form->data['user_name'] = $temp;
?>

!! not tested and may need debugging !!

Thanks Bob,
I'll get more help on stackoverflow
for debugging the code,
but I really appreciated you taking the time to post it.

I am now managing all of my many forms with Chronoforms
and I am always impressed at how flexible it is :-)

Tested!
this is the error I receive when filling the form with
an email like info@mydomain.com

YOU HAVE AN ERROR IN YOUR SQL SYNTAX; CHECK THE MANUAL THAT CORRESPONDS TO YOUR MYSQL SERVER VERSION FOR THE RIGHT SYNTAX TO USE NEAR ''INFO%''' AT LINE 3 SQL=SELECT `USERNAME` FROM `#__USERS` WHERE `USERNAME` LIKE 'INFO%'' ;

Hi oloccina,

It did need debugging - there was an extra quote ' after the % - there should be one, not two.

Bob

working like a breeze now, thank you!

coffee bought! :-)
