[Author]

I have built a user form where I would like the autogenerated username to be the user's first and last name.

I also want to make sure that the First and Last name fields are required.

Thank you

Hi Arrien,

Thank you for getting in touch.

To change the username you're going to have to Hook into the form and update the user fields .

Try using the function below.

add_action('cred_save_data', 'my_save_data_action',10,2);
function my_save_data_action($post_id, $form_data)
{
    // if a specific form
    if ($form_data['id']==12)
    {
          $firstname = $_GET['first_name'];
          $lastname = $_GET['last_name'];
          $user_name = $firstname+$lastname;
            wp_update_user(array( 'ID' => $post_id, 'username' => $user_name ));
        }
    }
}

Replace 12 with ID of your user form.

Secondly you can use the hook below to do a custom validation on the form for the first and last name.

Please let me know if this helps.

Hi Shane,

It doesn't seem to be working.

I've setup the function as a plug-in:

<?php
/*
Plugin Name: Save username
Description: Save username using First Name and Last Name
*/

//Save username using First Name and Last Name

add_action('cred_save_data', 'save_username',10,2);
function save_username($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==28)
{
$firstname = $_GET['first_name'];
$lastname = $_GET['last_name'];
$user_name = $firstname+$lastname;
wp_update_user(array( 'ID' => $post_id, 'username' => $user_name ));
}
}

What happens if I don't have the First name and last name required, what would the username save as?

Thank you,
Arrien

Hi Arrien,

Given that you will essentially make the first and last name required then it won't be possible to create a user without them entering their first and last name since the form validation won't work.

I've made an update to the code.

add_action('cred_save_data', 'save_username',10,2);
function save_username($post_id, $form_data)
{
// if a specific form
if ($form_data['id']==28)
{
$firstname = $_GET['first_name'];
$lastname = $_GET['last_name'];
$user_name = $firstname+$lastname;
wp_update_user(array( 'ID' => $post_id, 'user_login' => $user_name ));
}
}

Also please remember to create the custom validation for the first and last name.

If this still doesn't work please let me know and send me a link to the page where the registration form is.

Thanks,
Shane

Hi Shane,

The code is still not working and I think it might be because I'm editing the form in "Expert mode" because I have specific conditional statements to add that don't work in GUI mode.

Is there a way to make the username autogenerate with the form editing in "Expert mode"?

Also, I am not sure how to create the custom validation.

Thanks,
Arrien

Hi Arrien,

This shouldn't matter in a case like this.

Would you mind allowing me to have admin access to the site so that I can have a look ?

I've enabled the private fields for your next response.

Thanks,

Hi Arrien,

I've made some more adjustments to the code. Can you update the code to

add_action('cred_save_data', 'save_username',10,2);

function save_username($post_id, $form_data)


{

// if a specific form

if ($form_data['id']==28)

{

$firstname = $_POST['first_name'];

$lastname = $_POST['last_name'];

$user_name = $firstname.''.$lastname;
global $wpdb;
$wpdb->update($wpdb->users, array('user_login' =>$user_name ), array('ID' => $post_id));
}

}

Also can you remove the test users that I made here.

Great! That works really well!

Now, I am really not sure how to make the First and Last name fields required.

Thanks,
Arrien

Hi Arrien,

Here is the code below to make both fields required.

add_filter('cred_form_validate','my_validation',10,2);
function my_validation($error_fields, $form_data)
{
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    //uncomment this if you want to print the field values
    //print_r($fields);
    //validate if specific form
    if ($form_data['id']==28)
    {
        //check the first name value 
        if (empty($fields['first_name']['value']))
        {
            //set error message for first name
            $errors['my_field']='Please enter your first name';
        }
        //check the last name value 
        if (empty($fields['last_name']['value']))
        {
            //set error message for last name
            $errors['_featured_image'] = 'Please enter your last name';
        }
    }
    //return result
    return array($fields,$errors);
}

Please try this function and let me know if it helps.
Thanks,

Hi Shane,

That also worked quite well.

Is there a way to add a clear form fields button so that a person filling out the form can reset it if they've made a mistake?

Thanks,
Arrien

[Shane]

Hi Arrien,

Unfortunately no that won't be possible to do without some amount of custom code as we don't have a hook that can provide this functionality.

Thanks,
Shane

My issue is resolved now. Thank you!
