Add a mobile phone field on My account > edit account in Woocommerce

Question

my question: How to add mobile phone field in Woocommerce my-account/edit-account/ page (Related template: form-edit-account.php file)

Like in the following answer thread:
Saving the value of a custom field phone number in WooCommerce My account > Account details

But this answer code is incomplete as there is some missing hooked functions. Any help is appreciated to get something complete, meaning the field display.

Answer 1

You have 3 options to display a custom mobile phone field on My account > Edit account page:

1) As the first field using woocommerce_edit_account_form_start action hook (see below).

2) After existing fields using woocommerce_edit_account_form action hook:

// Display the mobile phone field
// add_action( 'woocommerce_edit_account_form_start', 'add_billing_mobile_phone_to_edit_account_form' ); // At start
add_action( 'woocommerce_edit_account_form', 'add_billing_mobile_phone_to_edit_account_form' ); // After existing fields
function add_billing_mobile_phone_to_edit_account_form() {
    $user = wp_get_current_user();
    ?>
     <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
        <label for="billing_mobile_phone"><?php _e( 'Mobile phone', 'woocommerce' ); ?> <span class="required">*</span></label>
        <input type="text" class="woocommerce-Input woocommerce-Input--phone input-text" name="billing_mobile_phone" id="billing_mobile_phone" value="<?php echo esc_attr( $user->billing_mobile_phone ); ?>" />
    </p>
    <?php
}

// Check and validate the mobile phone
add_action( 'woocommerce_save_account_details_errors','billing_mobile_phone_field_validation', 20, 1 );
function billing_mobile_phone_field_validation( $args ){
    if ( isset($_POST['billing_mobile_phone']) && empty($_POST['billing_mobile_phone']) )
        $args->add( 'error', __( 'Please fill in your Mobile phone', 'woocommerce' ),'');
}

// Save the mobile phone value to user data
add_action( 'woocommerce_save_account_details', 'my_account_saving_billing_mobile_phone', 20, 1 );
function my_account_saving_billing_mobile_phone( $user_id ) {
    if( isset($_POST['billing_mobile_phone']) && ! empty($_POST['billing_mobile_phone']) )
        update_user_meta( $user_id, 'billing_mobile_phone', sanitize_text_field($_POST['billing_mobile_phone']) );
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

3) In a specific location , overriding myaccount/form-edit-account.php template file via the theme as explained on this documentation . and on this answer thread …

In this case you will need to add the following html code in the template ( like in this answer thread ) :

 <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
    <label for="billing_mobile_phone"><?php _e( 'Mobile phone', 'woocommerce' ); ?> <span class="required">*</span></label>
    <input type="text" class="woocommerce-Input woocommerce-Input--phone input-text" name="billing_mobile_phone" id="billing_mobile_phone" value="<?php echo esc_attr( $user->billing_mobile_phone ); ?>" />
</p>

In this last case, you will need to add in your theme's function.php file the 2 last hooked functions from section 2 (validation and saving).
