How to Add WooCommerce Registration Form Fields

To begin, make sure that the WooCommerce registration forms are enabled on the account login page. For this, go to WooCommerce > Settings > Accounts and check Enable customer registration on the “My account” page.

After enabling this option, you can see the WooCommerce registration form at the frontend.

As should be obvious it is a pretty modest WooCommerce form, however, we can add more fields to this structure by utilizing the following actions. Presently, to include extra fields like first name, last name and phone number, and so on, include the following lines of code toward the end of your functions.php, which is located in your theme folder.

function wooc_extra_register_fields() {?>
       <p class="form-row form-row-wide">
       <label for="reg_billing_phone"><?php _e( 'Phone', 'woocommerce' ); ?></label>
       <input type="text" class="input-text" name="billing_phone" id="reg_billing_phone" value="<?php esc_attr_e( $_POST['billing_phone'] ); ?>" />
       </p>
       <p class="form-row form-row-first">
       <label for="reg_billing_first_name"><?php _e( 'First name', 'woocommerce' ); ?><span class="required">*</span></label>
       <input type="text" class="input-text" name="billing_first_name" id="reg_billing_first_name" value="<?php if ( ! empty( $_POST['billing_first_name'] ) ) esc_attr_e( $_POST['billing_first_name'] ); ?>" />
       </p>
       <p class="form-row form-row-last">
       <label for="reg_billing_last_name"><?php _e( 'Last name', 'woocommerce' ); ?><span class="required">*</span></label>
       <input type="text" class="input-text" name="billing_last_name" id="reg_billing_last_name" value="<?php if ( ! empty( $_POST['billing_last_name'] ) ) esc_attr_e( $_POST['billing_last_name'] ); ?>" />
       </p>
       <div class="clear"></div>
       <?php
 }
 add_action( 'woocommerce_register_form_start', 'wooc_extra_register_fields' );

Now if you refresh the page, you’ll see the fields being added to WooCommerce registration form.

To relate these registration form fields with the billing address, you have to include the prefix “billing_” before the field name. The following is a list of all the valid WooCommerce form fields that can be added to the registration form and can be associated with a billing address.

• billing_first_name
• billing_last_name
• billing_company
• billing_address_1
• billing_address_2
• billing_city
• billing_postcode
• billing_country
• billing_state
• billing_email
• billing_phone

Now we also need to validate these newly added form fields. To validate these structure fields, include the accompanying lines of code toward the end of your functions.php file which located in the theme folder.

/**

* register fields Validating.

*/

function wooc_validate_extra_register_fields( $username, $email, $validation_errors ) {

      if ( isset( $_POST['billing_first_name'] ) && empty( $_POST['billing_first_name'] ) ) {

             $validation_errors->add( 'billing_first_name_error', __( '<strong>Error</strong>: First name is required!', 'woocommerce' ) );

      }

      if ( isset( $_POST['billing_last_name'] ) && empty( $_POST['billing_last_name'] ) ) {

             $validation_errors->add( 'billing_last_name_error', __( '<strong>Error</strong>: Last name is required!.', 'woocommerce' ) );

      }
         return $validation_errors;
}

add_action( 'woocommerce_register_post', 'wooc_validate_extra_register_fields', 10, 3 );

On the off chance that you like into the code of this function, you’ll make sense that it is simply checking $_POST array for form values and including an error message if a value is not present or invalid data.

Along these lines, you can likewise include various validation rules and you also add validation rules to different fields as well. You can see one of our custom validation rules being applied:

At long last, we need to save these values to the database.

To insert values in database add the following function in your theme’s functions.php file:

 
/**
* Below code save extra fields.
*/
function wooc_save_extra_register_fields( $customer_id ) {
    if ( isset( $_POST['billing_phone'] ) ) {
                 // Phone input filed which is used in WooCommerce
                 update_user_meta( $customer_id, 'billing_phone', sanitize_text_field( $_POST['billing_phone'] ) );
          }
      if ( isset( $_POST['billing_first_name'] ) ) {
             //First name field which is by default
             update_user_meta( $customer_id, 'first_name', sanitize_text_field( $_POST['billing_first_name'] ) );
             // First name field which is used in WooCommerce
             update_user_meta( $customer_id, 'billing_first_name', sanitize_text_field( $_POST['billing_first_name'] ) );
      }
      if ( isset( $_POST['billing_last_name'] ) ) {
             // Last name field which is by default
             update_user_meta( $customer_id, 'last_name', sanitize_text_field( $_POST['billing_last_name'] ) );
             // Last name field which is used in WooCommerce
             update_user_meta( $customer_id, 'billing_last_name', sanitize_text_field( $_POST['billing_last_name'] ) );
      }

}
add_action( 'woocommerce_created_customer', 'wooc_save_extra_register_fields' );

And we are done here! Now the recently added fields have been added, validated, and inserted for future use.

On the billing address page in your account, you need to click on edit to go there. You can see the values from the registration form already being populated.

WooCommerce Edit My Account Page – An Alternative Method

If you wish to use an alternative method for registering WoOCommerce form fields, you can use WooCommerce hooks to edit WooCommerce my account page.

The following code snippet illustrates the process:

function woocommerce_edit_my_account_page() {
    return apply_filters( 'woocommerce_forms_field', array(
        'woocommerce_my_account_page' => array(
            'type'        => 'text',
            'label'       => __( 'Socail Media Profile Link', ' cloudways' ),
            'placeholder' => __( 'Profile Link', 'cloudways' ),
            'required'    => false,
        ),
    ) );
}

function edit_my_account_page_woocommerce() {
    $fields = woocommerce_edit_my_account_page();

    foreach ( $fields as $key => $field_args ) {
        woocommerce_form_field( $key, $field_args );
    }
}
add_action( 'woocommerce_register_form', 'edit_my_account_page_woocommerce', 15 );

Here’s how the outcome of the snippet would look like:

The above snippet starts with the woocommerce_edit_my_account_page() that is used in the later part of the snippet. This function returns a multidimensional array that contains the information about the fields (type, label, placeholder, required or not) that you are adding to the form.

To ensure that the values of the fields can be updated further on, the array is further processes through the woocommerce_form_field() function.

in the next half of the snippet, I have used the edit_my_account_page_woocommerce() function. As you can see the $fields variable contains the array generated by the woocommerce_edit_my_account_page() function. This is looped through using the foreach() loop.

Adding Your Required WooCommerce Form Field

As you can see this above mentioned snippet is very flexible and you can add any field type that you wish by providing the appropriate field structure value in the $fields array.

Here are a few examples:

Textarea

'woocommerce_my_account_page' => array(
         'type'        => 'textarea',
         'label'       => __( 'Socail Media Profile Link', 'cloudways' ),
         'placeholder' => __( 'Profile Link', 'cloudways' ),
         'required'    => false,
     ),

checkbox

'woocommerce_my_account_page_checkbox'   => array(
           'type'  => 'checkbox',
           'label' => __( 'Checkbox', 'cloudways' ),
       ),

Option list

'woocommerce_my_account_page_select'     => array(
           'type'    => 'select',
           'label'   => __( 'Select Field', 'cloudways' ),
           'options' => array(
               '' => __( 'Select an options.', 'cloudways' ),
               1  => __( 'WooCommerce forms', 'cloudways' ),
               2  => __( 'WooCommerce  my account page', 'cloudways' ),
               3  => __( 'WooCommerce edit my account page', 'cloudways' ),
               4  => __( 'How to edit WooCommerce my account page', 'cloudways' ),
               5  => __( 'Edit my account page WooCommerce', 'cloudways' ),
           ),

Here’s how these options would look like in the form:

You can save these values in the function wooc_save_extra_register_fields(), mentioned above.
