Add Custom registration fields in WooCommerce and phone field validation issue

由 强颜欢笑 提交于 2019-11-29 12:45:50

Note: Your special registration form located in the footer is something different than WooCommerce checkout fields.

In your code the hook for your validating function text_domain_woo_validate_reg_form_fields() is just missing. There is also some small errors (corrected)…

The best place to check the submitted data is your validation function and you should also need to add another one for checkout too (instead of using a custom pattern for checkout phone field, that is used to format data).

So all your related code should be:

## --- FOR CHECKOUT --- ##

// Checkout billing phone validation (Checking length)
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
    if ( $_POST['billing_phone'] && strlen($_POST['billing_phone']) < 10 )
        wc_add_notice( __('Please type a correct phone number…', 'woocommerce'), 'error' );
}

## --- FOR CUSTOM REGISTRATION FORM --- ##

// Add custom fields to registration form.
add_action('woocommerce_register_form_start', 'text_domain_woo_reg_form_fields');
function text_domain_woo_reg_form_fields() {
    ?>
    <div class="formumuz" style="display:flex;">
        <p class="form-row form-row-first">
            <label style="display:none!important;" for="billing_first_name"><?php _e('First name', 'woocommerce'); ?><span class="required">*</span></label>
            <input style="width: 130px; display: inline-block; margin-right:1px;" type="text" class="woocommerce-Input woocommerce-Input--text input-text placeholder" placeholder="İsim / Name *" type="text" class="input-text" name="billing_first_name" id="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 style="display:none!important;" for="billing_last_name"><?php _e('Last name', 'woocommerce'); ?><span class="required">*</span></label>
            <input style="width: 130px; display: inline-block; margin-left:1px;" type="text" class="woocommerce-Input woocommerce-Input--text input-text placeholder" placeholder="Soyisim / Surname *" type="text" class="input-text" name="billing_last_name" id="billing_last_name" value="<?php if (!empty($_POST['billing_last_name'])) esc_attr_e($_POST['billing_last_name']); ?>" />
        </p>
    </div>
    <p style="margin-bottom: 0px; margin-top: 10px;" class="form-row form-row-wide">
        <label style="display:none!important;" for="reg_billing_phone"><?php _e( 'Phone', 'woocommerce' ); ?></label>

        <!--  "You can’t have 2 times the value attribute and you can use "tel" type … (to be removed)" -->
        <input style="width:254px!important;" type="tel" class="woocommerce-Input woocommerce-Input--text input-text placeholder" placeholder="Cep Telefonu / Mobile *" name="billing_phone" id="reg_billing_phone" value="<?php esc_attr_e( $_POST['billing_phone'] ); ?>" /> *
    </p><br>
    <div class="clear"></div>
    <?php
}

// Checking & validation of custom fields in registration form.
add_action('woocommerce_register_post', 'text_domain_woo_validate_reg_form_fields', 10, 3);
function text_domain_woo_validate_reg_form_fields( $username, $email, $validation_errors ) {
    if (isset($_POST['billing_first_name']) && empty($_POST['billing_first_name'])) {
        $validation_errors->add('billing_first_name_error', __('İsim alanı zorunludur! / Name field is required!', 'woocommerce'));
    }
    if (isset($_POST['billing_last_name']) && empty($_POST['billing_last_name'])) {
        $validation_errors->add('billing_last_name_error', __('Soyisim alanı zorunludur! / Surname field is required!', 'woocommerce'));
    }
    if (isset($_POST['billing_phone']) && empty($_POST['billing_phone'])) {
        $validation_errors->add('billing_phone_error', __('Telefon alanı zorunludur! / Phone field is required!', 'woocommerce'));
    }

    // ==> CHECKING PHONE LENGTH (10 character minimal) <==
    if (isset($_POST['billing_phone']) && strlen($_POST['billing_phone']) < 10 ) {
        $validation_errors->add('billing_phone_error', __('Please type a correct phone number…', 'woocommerce'));
    }
    return $validation_errors;
}

// Add custom fields to registration form.
add_action( 'woocommerce_created_customer', 'custom_save_extra_register_fields' ); // <==== Missing
function custom_save_extra_register_fields($customer_id) {
    //First name field
    if (isset($_POST['billing_first_name'])) {
        update_user_meta($customer_id, 'first_name', sanitize_text_field($_POST['billing_first_name']));
        update_user_meta($customer_id, 'billing_first_name', sanitize_text_field($_POST['billing_first_name']));
    }
    //Last name field
    if (isset($_POST['billing_last_name'])) {
        update_user_meta($customer_id, 'last_name', sanitize_text_field($_POST['billing_last_name']));
        update_user_meta($customer_id, 'billing_last_name', sanitize_text_field($_POST['billing_last_name']));
    }
     //Phone field
    if (isset($_POST['billing_phone'])) {
        update_user_meta($customer_id, 'phone', sanitize_text_field($_POST['billing_phone']));
        update_user_meta($customer_id, 'billing_phone', sanitize_text_field($_POST['billing_phone']));
    }
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Tested and works

Each time the phone number minimal length will be checked and display this alert (if needed):
