在WooCommerce结帐中选中一个复选框时显示一个必填文本字段 [英] show a required text field when a checkbox is checked in WooCommerce checkout
问题描述
我正在研究带有自定义复选框的woocommerce注册解决方案。
I working on a solution in woocommerce registration with custom checkbox.
该计划是,当有人选择自定义复选框时,将打开一个附加文本字段,并且是必需的。
The plan is when somebody select the custom checkbox an additional textfield opens and have to be required.
起作用的部分:
// add the special customer role
add_action('admin_init', 'uiwc_new_role');
function uiwc_new_role() {
add_role(
'kundenkarte',
"Kundenkarte",
array(
'read' => true,
'delete_posts' => false
)
);
}
add_action( 'woocommerce_after_order_notes', 'custom_checkout_field_with_wholesale_option' );
function custom_checkout_field_with_wholesale_option( $checkout ) {
if( current_user_can( 'wholesale_customer' ) ) return; // exit if it is "wholesale customer"
echo '<div id="wholesale_checkbox_wrap">';
woocommerce_form_field('wholesale_checkbox', array(
'type' => 'checkbox',
'class' => array('input-checkbox'),
'label' => __('Do you have a Customer Card?'),
'placeholder' => __('card'),
'required' => false,
'value' => true
), '');
echo '</div>';
}
// Conditionally change customer user role
add_action( 'woocommerce_checkout_update_order_meta', 'wholesale_option_update_user_meta' );
function wholesale_option_update_user_meta( $order_id ) {
if ( isset($_POST['wholesale_checkbox']) ) {
$user_id = get_post_meta( $order_id, '_customer_user', true ); // Get user ID
if( $user_id > 0 ){
$user = new WP_User($user_id);
$user->remove_role('customer');
$user->add_role('kundenkarte');
}
}
}
我的PHP知识非常低。

使用以下代码,请选中您的复选框可见所需的自定义必填文本字段(带有验证并另存为用户元数据和订单元数据):
With the code below, when your checkbox is checked a custom required text field is visible (with validation and save as user meta data and order meta data):
add_action( 'woocommerce_after_order_notes', 'custom_checkout_field_with_wholesale_option' );
function custom_checkout_field_with_wholesale_option( $checkout ) {
if( current_user_can( 'wholesale_customer' ) ) return; // exit if it is "wholesale customer"
echo '<style> #wholesale_card_field.hidden { display:none; }</style>
<div id="wholesale_checkbox_wrap">';
woocommerce_form_field('wholesale_checkbox', array(
'type' => 'checkbox',
'class' => array('input-checkbox'),
'label' => __('Do you have a Customer Card?'),
'placeholder' => __('card'),
'required' => false,
'value' => true
), '');
woocommerce_form_field('wholesale_card', array(
'type' => 'text',
'class' => array('hidden'),
'placeholder' => __('Customer card Id'),
'required' => true,
), '');
echo '</div>';
?>
<script>
jQuery(function($){
$('#wholesale_checkbox_field input').click(function(){
if( $(this).is(':checked')) {
$('#wholesale_card_field').css('display', 'none').removeClass('hidden').show();
} else if ( ! $(this).is(':checked') && $('#wholesale_card_field').css('display') !== 'none' ) {
$('#wholesale_card_field').hide();
}
});
});
</script>
<?php
}
// Validation
add_action( 'woocommerce_checkout_process', 'wholesale_option_validation' );
function wholesale_option_validation() {
if ( isset($_POST['wholesale_checkbox']) && isset($_POST['wholesale_card']) && empty($_POST['wholesale_card']) ) {
wc_add_notice( __("Please fill in your customer card Id"), "error" );
}
}
// Conditionally change customer user role and add customer card as order and user meta
add_action( 'woocommerce_checkout_update_order_meta', 'wholesale_option_update_meta' );
function wholesale_option_update_meta( $order_id ) {
if ( isset($_POST['wholesale_checkbox']) ) {
$user_id = get_post_meta( $order_id, '_customer_user', true ); // Get user ID
if( $user_id > 0 ){
$user = new WP_User($user_id);
$user->remove_role('customer');
$user->add_role('kundenkarte');
}
// Add customer card Id as order metadata
if ( isset($_POST['wholesale_card']) ) {
update_post_meta( $order_id, 'wholesale_card', sanitize_text_field( $_POST['wholesale_card'] ) );
if( $user_id > 0 )
update_user_meta( $user_id, 'wholesale_card', sanitize_text_field( $_POST['wholesale_card'] ) );
}
}
}
// Display customer card on admin order edit page under billing address
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_wholesale_option_admin_order', 10, 1 );
function display_wholesale_option_admin_order( $order ){
echo '<p><strong>'.__('Card Id').':</strong> ' . $order->get_meta( 'wholesale_card' ) . '</p>';
}
代码进入活动子主题(或活动主题)的functions.php文件中。经过测试,可以正常工作。
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
