Plugin API/Action Reference/register form


The 'register_form' action hook is used to customize the built-in WordPress registration form.

Use in conjunction with 'registration_errors' (for validation) and 'register_post' (save extra data) when customizing registration.

WordPress MS Note: For Wordpress MS (Multi-Site), use the 'signup_header' action to redirect users away from the signup.


This example demonstrates how to add a new field to the registration form. Keep in mind that this won't be saved automatically. You will still need to set up validation rules and manually handle saving of the additional form fields.

add_action( 'register_form', 'myplugin_add_registration_fields' );

function myplugin_add_registration_fields() {

    //Get and set any values already sent
    $user_extra = ( isset( $_POST['user_extra'] ) ) ? $_POST['user_extra'] : '';

        <label for="user_extra"><?php _e( 'Extra Field', 'myplugin_textdomain' ) ?><br />
            <input type="text" name="user_extra" id="user_extra" class="input" value="<?php echo esc_attr( stripslashes( $user_extra ) ); ?>" size="25" /></label>


To modify or translate the registration form , page or fieldnames, you can use the following function:

function my_translate() {

   $your_content = ob_get_contents();
   $your_content = preg_replace( '/\<label for="user_login"\>(.*?)\<br/', 'Usernumia: ', $content );
   $your_content = preg_replace( '/\<label for="user_email"\>(.*?)\<br/', 'Email Sior:', $content );

   echo $your_content;
add_action( 'register_form', 'my_translate' );

Choose the codes/blocks for translation accurately, otherwise the above function may change other parts of the registration page.
