Saving fields to user registration form

  • I have tried and tried to find the documentation as to whether this is possible but can’t seem to find a proper answer, so…

    I have a user registration form on my front end and have combined it with some ACF forms:

    <form name="registerform" id="registerform" action="<?php echo site_url('wp-login.php?action=register', 'login_post') ?>" method="post">
    						<label for="user_login">Username</label>
    						<input type="text" name="user_login" id="user_login" class="input" value="">
    						<label for="user_email">E-mail</label>
    						<input type="text" name="user_email" id="user_email" class="input" value="">
    						<?php $options = array(
    						    'post_id' => 'user_'.$current_user->ID,
    						    'field_groups' => array(136),
    						    'form' => false, 
    						    //'return' => add_query_arg( 'updated', 'true', get_permalink() ), 
    						    'html_before_fields' => '',
    						    'html_after_fields' => '',
    						    //'submit_value' => 'Update' 
    						acf_form( $options );
    						<p style="display:none">
    						<label for="confirm_email">Please leave this field empty</label>
    						<input type="text" name="confirm_email" id="confirm_email" class="input" value="">
    						<p id="reg_passmail">A password will be e-mailed to you.</p>
    						<input type="hidden" name="redirect_to" value="login/?action=register&success=1" />
    						<p class="submit"><input type="submit" name="wp-submit" id="wp-submit" class="button button-primary button-large" value="Register" /></p>

    It saves and a new user is created but none of the other values are added, i’ve seen some things about hooking in to the registration but I can’t see how i’d do that here?

    Any help that could point me in the right direction would be massively appreciated!

    Thanks in advance

  • having the same issue, did you ever find a solution?

  • Hi @dhod and @bowersinit

    when using acf_form within another field like this there’s no automagic saving happening so you’ll have to do that yourself (as you figured out).

    I think what you need is to hook into the user_register action:

    and save the ACF input values to their respective fields. Something like:

    function save_additional_user_meta( $user_id ) {
        if ( isset( $_POST['NAME PARAMETER OF THE ACF INPUT FIELD'] ) )
            update_user_meta($user_id, 'first_name', $_POST['NAME PARAMETER OF THE ACF INPUT FIELD']);
    add_action( 'user_register', 'save_additional_user_meta', 10, 1 );
  • Thanks Jonathan, but i dont seem to be able to make this work, this it the markup of one of the fields im trying to save:

    <input type="number" id="acf-field-price_from" class="number" min="1" max="10000000000000000" step="1" name="fields[field_55e57136adc2e]" value="" placeholder="">

    and this is the hook im adding to my themes functions file:

    function save_additional_user_meta( $user_id ) {
        if ( isset( $_POST['field_55e57136adc2e'] ) )
            update_user_meta($user_id, 'number_of_bedrooms', $_POST['field_55e57136adc2e']);
    add_action( 'user_register', 'save_additional_user_meta', 10, 1 );

    ive tried using the id (acf-field-price_from), name (fields[field_55e57136adc2e]) and field key (field_55e57136adc2e) for the post id, and nothing is getting saved to the db

    i tested the hook by removing the if isset, like this

    function save_additional_user_meta( $user_id ) {
    	update_user_meta($user_id, 'number_of_bedrooms', 'test');
    add_action( 'user_register', 'save_additional_user_meta', 10, 1 );

    and it saves the “number_of_bedrooms” as test, so i know the hook is working, just the syntax might be wrong on the field save function?

    any help is much apreciated

  • Hi @bowersinit

    When an input has a name value like fields[field_55e57136adc2e] the $_POST value will actually be an array called fields with a fieldkey of field_55e57136adc2e which in term contains the value.

    So try this out:

    function save_additional_user_meta( $user_id ) {
        if ( isset( $_POST['fields']['field_55e57136adc2e'] ) )
            update_user_meta($user_id, 'number_of_bedrooms', $_POST['fields']['field_55e57136adc2e']);
    add_action( 'user_register', 'save_additional_user_meta', 10, 1 );
  • Thanks Jonathan, that works when i hook it into the register form, but if i add it into a modal popup login form (using AJAX) the fields are empty, im guessing it has something to do with the ajax saving things in a different way? or am i way off the point here?

  • Are your modal login form also for registering then? Is it part of a plugin?

  • yes, the modal popups handle login and registration, here is the script that handles all that stuff:

    function ajax_auth_init(){	
    	wp_register_style( 'ajax-auth-style', get_template_directory_uri() . '/css/ajax-auth-style.css' );
    	wp_register_script('validate-script', get_template_directory_uri() . '/js/jquery.validate.js', array('jquery') ); 
        wp_register_script('ajax-auth-script', get_template_directory_uri() . '/js/ajax-auth-script.js', array('jquery') ); 
        wp_localize_script( 'ajax-auth-script', 'ajax_auth_object', array( 
            'ajaxurl' => admin_url( 'admin-ajax.php' ),
            'redirecturl' => home_url(),
            'loadingmessage' => __('Sending user info, please wait...')
        // Enable the user with no privileges to run ajax_login() in AJAX
        add_action( 'wp_ajax_nopriv_ajaxlogin', 'ajax_login' );
    	// Enable the user with no privileges to run ajax_register() in AJAX
    	add_action( 'wp_ajax_nopriv_ajaxregister', 'ajax_register' );
    // Execute the action only if the user isn't logged in
    if (!is_user_logged_in()) {
        add_action('init', 'ajax_auth_init');
    function ajax_login(){
        // First check the nonce, if it fails the function will break
        check_ajax_referer( 'ajax-login-nonce', 'security' );
        // Nonce is checked, get the POST data and sign user on
      	// Call auth_user_login
    	auth_user_login($_POST['username'], $_POST['password'], 'Login'); 
    function ajax_register(){
        // First check the nonce, if it fails the function will break
        check_ajax_referer( 'ajax-register-nonce', 'security' );
        // Nonce is checked, get the POST data and sign user on
        $info = array();
      	$info['user_nicename'] = $info['nickname'] = $info['display_name'] = $info['first_name'] = $info['user_login'] = sanitize_user($_POST['username']) ;
        $info['user_pass'] = sanitize_text_field($_POST['password']);
    	$info['user_email'] = sanitize_email( $_POST['email']);
    	// Register the user
        $user_register = wp_insert_user( $info );
     	if ( is_wp_error($user_register) ){	
    		$error  = $user_register->get_error_codes()	;
    		if(in_array('empty_user_login', $error))
    			echo json_encode(array('loggedin'=>false, 'message'=>__($user_register->get_error_message('empty_user_login'))));
    			echo json_encode(array('loggedin'=>false, 'message'=>__('This username is already registered.')));
            echo json_encode(array('loggedin'=>false, 'message'=>__('This email address is already registered.')));
        } else {
    	  auth_user_login($info['nickname'], $info['user_pass'], 'Registration');       
    function auth_user_login($user_login, $password, $login)
    	$info = array();
        $info['user_login'] = $user_login;
        $info['user_password'] = $password;
        $info['remember'] = true;
    	$user_signon = wp_signon( $info, false );
        if ( is_wp_error($user_signon) ){
    		echo json_encode(array('loggedin'=>false, 'message'=>__('Wrong username or password.')));
        } else {
            echo json_encode(array('loggedin'=>true, 'message'=>__($login.' successful, redirecting...')));

    ive tried putting code after the Register the user like this:`
    $user_register = wp_insert_user( $info );
    update_user_meta($info_id, ‘number_of_bedrooms’, $_POST[‘fields’][‘field_55e56dfdabccb’]);`

    but this doesnt even save an empty value to “number_of_bedrooms” in the usermeta table.

    as i understand it, wp_insert_user returns the user id as $info once it successfully registers the user, i guess im missing something somewhere?

  • The hook user_register should run just the same as when you’re registering a user not through AJAX..

    However the function wp_insert_user will return the new user id if successful so you should be able to do this right after:

    update_user_meta($user_register, 'number_of_bedrooms', $_POST['fields']['field_55e56dfdabccb']);
