[FIXED] Redirect user after registration via separate registration page to a specific page in WooCommerce

Issue

I need to redirect users when they click the register button to the my-account billing page. I had this working perfectly using via the code from Redirect after registration to WooCommerce "my account" edit address page answer code.

However that was when the register and login pages were on the same page, now however I've had to make a different registration page using the code:

add_shortcode( 'wc_reg_form_bbloomer', 'bbloomer_separate_registration_form' );
    
function bbloomer_separate_registration_form() {
   if ( is_admin() ) return;
   if ( is_user_logged_in() ) return;
   ob_start();
 
   // NOTE: THE FOLLOWING <FORM></FORM> IS COPIED FROM woocommerce\templates\myaccount\form-login.php
   // IF WOOCOMMERCE RELEASES AN UPDATE TO THAT TEMPLATE, YOU MUST CHANGE THIS ACCORDINGLY
 
   do_action( 'woocommerce_before_customer_login_form' );
 
   ?>
      <form method="post" class="woocommerce-form woocommerce-form-register register" <?php do_action( 'woocommerce_register_form_tag' ); ?> >
 
         <?php do_action( 'woocommerce_register_form_start' ); ?>
 
         <?php if ( 'no' === get_option( 'woocommerce_registration_generate_username' ) ) : ?>
 
            <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
               <label for="reg_username"><?php esc_html_e( 'Username', 'woocommerce' ); ?> <span class="required">*</span></label>
               <input type="text" class="woocommerce-Input woocommerce-Input--text input-text" name="username" id="reg_username" autocomplete="username" value="<?php echo ( ! empty( $_POST['username'] ) ) ? esc_attr( wp_unslash( $_POST['username'] ) ) : ''; ?>" /><?php // @codingStandardsIgnoreLine ?>
            </p>
 
         <?php endif; ?>
 
         <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
            <label for="reg_email"><?php esc_html_e( 'Email address', 'woocommerce' ); ?> <span class="required">*</span></label>
            <input type="email" class="woocommerce-Input woocommerce-Input--text input-text" name="email" id="reg_email" autocomplete="email" value="<?php echo ( ! empty( $_POST['email'] ) ) ? esc_attr( wp_unslash( $_POST['email'] ) ) : ''; ?>" /><?php // @codingStandardsIgnoreLine ?>
         </p>
 
         <?php if ( 'no' === get_option( 'woocommerce_registration_generate_password' ) ) : ?>
 
            <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
               <label for="reg_password"><?php esc_html_e( 'Password', 'woocommerce' ); ?> <span class="required">*</span></label>
               <input type="password" class="woocommerce-Input woocommerce-Input--text input-text" name="password" id="reg_password" autocomplete="new-password" />
            </p>
 
         <?php else : ?>
 
            <p><?php esc_html_e( 'A password will be sent to your email address.', 'woocommerce' ); ?></p>
 
         <?php endif; ?>
 
         <?php do_action( 'woocommerce_register_form' ); ?>
 
         <p class="woocommerce-FormRow form-row">
            <?php wp_nonce_field( 'woocommerce-register', 'woocommerce-register-nonce' ); ?>
            <button type="submit" class="woocommerce-Button woocommerce-button button woocommerce-form-register__submit" name="register" value="<?php esc_attr_e( 'Next', 'woocommerce' ); ?>"><?php esc_html_e( 'Next', 'woocommerce' ); ?></button>
         </p>
 
         <?php do_action( 'woocommerce_register_form_end' ); ?>
 
      </form>
 
   <?php
     
   return ob_get_clean();
}

Source: WooCommerce: Separate Login and Registration Pages

This now redirects me to a 404 of

register-now/edit-address/billing/

And I need it to redirect me to

my-account/edit-address/billing/

Solution

You should replace the code from the woocommerce_registration_redirect filter hook with:

function filter_woocommerce_registration_redirect( $redirect ) {
    return get_permalink( get_option( 'woocommerce_myaccount_page_id') ) . 'edit-address/billing';
}
add_filter( 'woocommerce_registration_redirect', 'filter_woocommerce_registration_redirect', 10, 1 );
