Adding more textfields to register form with hooks?

Hello again, i’m trying to solve my issue but i don’t think it’s currently possible, but wanted to verify.

First what i did was write a couple of functions in functions.php to add the standard first-name & last-name fields in my register form. This worked but as you might know, they get added at the back of the form below everything else. By using add_action( ‘register_form’, ‘custom_register_form’ );
I’m looking for something to add to infront or below your dropdown selector for pools.

Now i tried looking for do_action or apply_filters in the php files and cannot seem to find anything that would help me other then a function you called registration_form_extra_fields which is exactly where i would want to add below or above.

Is there a hook that i missed where i would be able to make a custom plugin for your plugin that would allow me to address that area?

Thanks in advance!

Here’s a little update, i found a hook where i can apply both textfields in a seperate plugin, the layout works, but i cannot get error codes to appear.
I tried adapting from your code, but it’s still very advanced for me and everything gets me to a critical error.

Any help would be appreciated.

For the error codes you need to hook into the filter ‘registration_errors’. I added it in your code.
```
<?php
/**
 * Plugin Name: Football Pool Register First & Last name
 * Description: Add 2 obligated fields where people need to add their name.
 * Version: 1.0
 * Author: Juanito Clyncke
 * Author URI: mailto:[email protected]
 * License: MIT
 */

// Save this plugin in the wp-content/plugins folder and activate it //

add_filter( 'plugins_loaded', array( 'FootballPoolRegisterNames', 'init_extension' ) );

class FootballPoolRegisterNames {
	public static function init_extension() {
		add_action( 'register_form', [__CLASS__, 'registration_form_extra_names'], null, 2 );
		add_filter( 'registration_errors', [__CLASS__, 'registration_check_fields'], null, 3 );
	}
	
	//1. Add fields. Just the basic layout added before the dropdown.
	public static function registration_form_extra_names() {
		$first_name = ( ! empty( $_POST['first_name'] ) ) ? sanitize_text_field( $_POST['first_name'] ) : '';?>
        <p>
            <label for="first_name">Voornaam</label>
            <input type="text" name="first_name" id="first_name" class="input" value="<?php echo esc_attr(  $first_name  ); ?>" size="25" autocomplete="voornaam" required="required">
        </p>
        <?php
    	$last_name = ( ! empty( $_POST['last_name'] ) ) ? sanitize_text_field( $_POST['last_name'] ) : '';?>
        <p>
            <label for="last_name">Achternaam</label>
            <input type="text" name="last_name" id="last_name" class="input" value="<?php echo esc_attr(  $last_name  ); ?>" size="25" autocomplete="achternaam" required="required">
        </p>
        <?php
	}

	//2. Check fields
	private static function check_field( &$errors, $field, $message ) {
		if ( Football_Pool_Utils::post_string( $field ) === '' ) {
			$errors->add( "{$field}_error", "<strong>Fout:</strong> vul je {$message} in." );
		}
	}

	public static function registration_check_fields( $errors ) {
		// Check the added fields
		self::check_field( $errors, 'first_name', 'voornaam' );
		self::check_field( $errors, 'last_name', 'achternaam' );

		return $errors;
	}

}
```
Next step would be to add a hook to the action that saves the user data (‘user_register‘), and then do a call to wp_update_user. E.g. something like this:
```
wp_update_user( [
    'ID' => $user_id, // this is the ID of the user you want to update.
    'first_name' => $first_name,
    'last_name' => $last_name,
] );
```
Hope this helps.

p.s. I removed the translations because there is no use for it when you don’t set a domain.

Hey AntoineH!
Thanks for the tips in the right direction, your code worked indeed, but i searched a few hours and could not get it to savethe first and last name(it did save everything else). After about 4/5 hours looking and testing i gave up and watched a movie, until suddenly it came to me, I have access to ChatGPT!

So i thought might as well give it a try, and what do you know it spit out a perfect working function based on the code we already made.
It uses “update_user_meta” though instead of the provided “wp_update_user” which i think makes sense since both are stored as meta data in the database in a separate table. Either way it works like a charm now! You can see the wonderful interaction below lol.

I thought i’d share it with you since it might be usefull for other people someday who decide they also want to add first/last names as required fields. I added your name/email back in the plugin since this was mostly you and ChatGPT and it’s your wonderfull plugin, you deserve all the credit.

Link to php code.

Oh wow, that is absolutely awesome. I’ve used ChatGPT in several occasions for rewriting texts, but not yet for development. This is quite amazing and very handy indeed.
