Registration Support

Hi Jen,

Sorry for delayed reply.

My Account is a page served by WooCommerce and I’m sure there might be plenty of free plugins which adds fields to this page. You can also ask WooCommerce this question.

You can though add following code in theme’s functions.php.

Step 1: Hook to display a new field in WooCommerce Register Form

add_action( 'woocommerce_register_form', 'ctm_function_wc_register_form' );  
	function ctm_function_wc_register_form(){
	global $woocommerce;
	?>
	   <div class="clear"></div>
	   <p class="form-row form-row-wide">
	   <label for="reg_billing_phone"><?php _e( 'Phone', 'woocommerce' ); ?><span class="required">*</span></label>
	   <input type="text" class="input-text" name="billing_phone" id="reg_billing_phone" value="<?php if ( ! empty( $_POST['billing_phone'] ) ) esc_attr_e( $_POST['billing_phone'] ); ?>" />
	   </p>
	}

Step 2: Add below code if you want that field to be a mandatory field.

add_filter( 'woocommerce_registration_errors', ctm_function_wc_register_form1,10, 3);
  function ctm_function_wc_register_form1($errors, $username, $email){	
							if ( isset( $_POST['billing_phone'] ) && empty( $_POST['billing_phone'] ) ) {
					$errors->add( 'billing_phone_error', __( '<strong>Billing Phone</strong>:  is a required field', 'woocommerce' ) );
				}
				return $errors;
			}

Step 3: Code to save the data in user meta data

add_action( 'woocommerce_created_customer', ctm_function_wc_register_form3,10, 3);
	function ctm_function_wc_register_form3( $customer_id ) {
				if ( isset( $_POST['billing_phone'] ) ) {
					update_user_meta( $customer_id, 'billing_phone', sanitize_text_field( $_POST['billing_phone'] ) );					
				}
			}
