International Phone Number Format

Once the plugin is activated, navigate to WooCommerce > Settings > International Phone Number Format tab in your WordPress admin dashboard.

Yes, you can add new fields using the intl_phone_number_format_fields filter.

Certainly. if you wish to add a Shipping Phone number field named shipping_phone to the checkout fields, it will be automatically formatted using the international phone number mask. If the field is set as required, it will undergo validation both in the frontend and backend as a valid number. Here's how you can achieve that: <?php add_filter('woocommerce_shipping_fields', function ($fields) { $fields['shipping_phone']['type'] = 'tel'; $fields['shipping_phone']['label'] = __('Shipping Phone Number', 'woocommerce'); $fields['shipping_phone']['class'] = array('form-row-wide'); $fields['shipping_phone']['required'] = false; return $fields; }, 10, 1);

Of course, let's say you want to add a "Mobile Phone Number" field to user account details in WooCommerce: Add the custom field using the intl_phone_number_format_fields filter. Here's an example code snippet: <?php add_filter('intl_phone_number_format_fields', function ($fields){ $fields[] = array( 'id' => 'mobile', 'enable' => true, 'desc' => 'Mobile phone number on the profile page', 'label' => 'Mobile', 'frontend_validation' => true, // JS frontend validation 'backend_validation' => true, // Backend validation 'countries' => 'all', // Countries related to fields (all, billing, or shipping) 'type' => 'custom', // Field type (custom, billing, or shipping) ); return $fields; }); Display the added field in the frontend "My Account" details section. Use the following code: <?php add_action('woocommerce_edit_account_form_start', function () { $user = wp_get_current_user(); ?> <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide"> <label for="mobile"><?php _e('Mobile phone', 'woocommerce'); ?> <span class="required">*</span></label> <input type="text" class="woocommerce-Input woocommerce-Input--phone input-text" name="mobile" id="mobile" value="<?php echo esc_attr($user->mobile); ?>" /> </p> <?php }); Implement validation for the field. Use the woocommerce_save_account_details_errors action hook along with the intl validation service: <?php add_action('woocommerce_save_account_details_errors', function (WP_Error $errors) { $fields = (new IPNFP_Fields_Service)->get_fields(); $validated = (new IPNFP_Validate_Service)->validate($fields); if (!empty($validated)) { foreach ($validated as $field => $error) { $errors->add($field, $error); } } }, 10, 1); Save the user's input for the field: <?php add_action('woocommerce_save_account_details', function (int $user_id) { if (isset($_POST['mobile'])) { $mobile = sanitize_text_field($_POST['mobile']); update_user_meta($user_id, 'mobile', $mobile); } }, 10, 1); In case the JS file is not included, you can include it using: <?php add_filter('intl_phone_number_format_validate_enqueue_js', function ($valid){ if (is_account_page()) { $valid = true; } return $valid; }); By following these steps, the field should be included and formatted with the International Phone Number Format mask.

You have the flexibility to add custom validation using regular expressions for specific countries. If you need to enforce a specific format for phone numbers in a particular country, you can achieve this by the intl_phone_number_format_custom_country_prefixes_validation filter. Here's an example scenario: Let's assume you want to apply custom validation rules for Libyan phone numbers, allowing only a specific format. In this case, you can utilize the following filter to associate the country calling code with the regular expression pattern: <?php // The structure should follow this format: // 'calling code' => 'regular expression pattern' add_filter('intl_phone_number_format_custom_country_prefixes_validation', function ($patterns) { $patterns['+218'] = '^\+2189[1-6][0-9]{7}$'; return $patterns; });

The plugin provides several filters that allow you to modify the fields, including built-in fields such as billing_phone, _billing_phone, shipping_phone, and _shipping_phone, as well as custom fields that you added using intl_phone_number_format_fields filter. This filter allows you to enable or disable the field. intl_phone_number_format_modify_{FIELD}_enable This filter allows you to enable or disable JS frontend validation for the specified field. intl_phone_number_format_modify_{FIELD}_frontend_validation This filter to enable or disable backend validation for the specified field. intl_phone_number_format_modify_{FIELD}_backend_validation This filter to adjust the countries that will be shown as calling codes for the field. Accepted values are: all, billing, and shipping. intl_phone_number_format_modify_{FIELD}_countries This filter to define the field type. For example, if the field is related to billing, set it as billing. If it's for shipping, set it as shipping. Otherwise, set it as custom. intl_phone_number_format_modify_{FIELD}_type
