在WooCommerce中,我试图隐藏一个自定义添加的字段,只要"免费送货"被选中(自动选择,基于订单金额)。
我在想我找到了一个包含以下代码的解决方案,但是当我在新的(隐身)浏览器窗口中加载页面时,该字段存在,如果刷新它,则该字段再次隐藏
// Hide address field, when Free Shipping mode is selected
add_filter('woocommerce_checkout_fields', 'xa_remove_billing_checkout_fields');
function xa_remove_billing_checkout_fields($fields) {
$shipping_method ='free_shipping:5'; // Set the desired shipping method to hide the checkout field(s).
global $woocommerce;
$chosen_methods = WC()->session->get( 'chosen_shipping_methods' );
$chosen_shipping = $chosen_methods[0];
if ($chosen_shipping == $shipping_method) {
unset($fields['billing']['billing_field_432']); // Add/change filed name to be hide
}
return $fields;
}
感谢任何帮助。

由于这是一个直播活动,您需要使用javascript / jQuery才能使其正常工作。您的“billing_field_432”必须不是必需的,因为当隐藏字段并尝试提交订单时,将为此自定义结帐字段生成错误通知消息。
根据'free_shipping:5'运送方式显示/隐藏该字段的代码:
// Conditional Show hide checkout fields based on chosen shipping methods
add_action( 'wp_footer', 'conditionally_hidding_billing_custom_field' );
function conditionally_hidding_billing_custom_field(){
// Only on checkout page
if( ! is_checkout() ) return;
// HERE your shipping methods rate ID "Free shipping"
$free_shipping = 'free_shipping:5';
?>
<script>
jQuery(function($){
// Choosen shipping method selectors slug
var sm = 'input[name^="shipping_method"]',
smc = sm + ':checked',
cbf = '#billing_field_432_field',
ihc = 'input[name="hidden_check"]';
// Function that shows or hide imput select fields
function showHide( selector = '', action = 'show' ){
if( action == 'show' )
$(selector).show( 200, function(){
$(this).addClass("validate-required");
$(ihc).val('1'); // Set hidden field for checkout process
});
else
$(selector).hide( 200, function(){
$(this).removeClass("validate-required");
$(ihc).val(''); // Set hidden field for checkout process
});
$(selector).removeClass("woocommerce-validated");
$(selector).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
}
// Initialising: Hide if choosen shipping method is "Free Shipping" method
if( $(smc).val() == '<?php echo $free_shipping; ?>' )
showHide( cbf, 'hide' );
else
$(ihc).val('1'); // Set hidden field for checkout process
// Live event (When shipping method is changed): Show or Hide based on "Free Shipping" method
$( 'form.checkout' ).on( 'change', sm, function() {
if( $(smc).val() == '<?php echo $free_shipping; ?>' )
showHide( cbf, 'hide' );
else
showHide( cbf );
});
});
</script>
<?php
}
添加自定义结帐隐藏输入字段以在'billing_field_432'
未隐藏时启用“必需”字段选项检查过程的代码:
// Add a hidden input field for "required" option check process
add_filter('woocommerce_checkout_fields', 'add_custom_hidden_input_field' );
function add_custom_hidden_input_field( $fields ) {
echo '<input type="hidden" id="hidden_check" name="hidden_check" value="">';
return $fields;
}
// Check custom checkout field "billing_field_432" when not hidden
add_action('woocommerce_checkout_process', 'check_custom_field_checkout_process');
function check_custom_field_checkout_process() {
// Check if set, if its not set add an error.
if ( isset( $_POST['hidden_check'] ) && $_POST['hidden_check'] && empty( $_POST['billing_field_432'] ) )
wc_add_notice( __( 'Please enter something in "billing field 432".' ), 'error' ); // SET your custom error notice
}
此代码位于您的活动子主题(或主题)的function.php文件中。经过测试和工作。
它基于:Conditionally hide a Checkout field in WooCommerce based on chosen shipping
当您使用最低订购金额为“50”和hiding other shipping methods when "free shipping" is available的免费送货方式时。你应该改用它:
// Unset checkout field based on cart amount for free shipping
add_filter('woocommerce_checkout_fields', 'remove_checkout_billing_field_432', 999 );
function remove_checkout_billing_field_432( $fields ) {
if ( WC()->cart->cart_contents_total >= 50 ) {
unset($fields['billing']['billing_field_432']); // Unset field
}
return $fields;
}
