根据用户角色隐藏 WooCommerce 上的自定义结帐字段
Hide Custom Checkout Fields on WooCommerce Based on User Role
我已经创建了一个 CSR 用户角色和几个自定义结账字段以显示在 WooCommerce 的结账页面上，我想对除具有 CSR 角色的用户之外的任何其他用户隐藏这些结账字段。
我已经创建了字段和角色，但是我的字段有些问题，因为它们仍然对所有用户显示。我按照教程 here 隐藏了字段。如果代码格式不正确，我们深表歉意。当我从 Atom 中提取格式时，编辑器不接受我的大部分格式。
添加自定义字段
add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );
function my_custom_checkout_field( $checkout ) {
echo '<div class="my_custom_checkout_field"><h2>' . __('CSR Information')

添加 CSR 角色

隐藏除 CSR 之外的所有人的 CSR 价值观

我已经扩展了我在教程中发布的关于如何 customize the WooCommerce Checkout 的代码。
首先您需要注册新的结帐字段。这是我添加 current_user_can() 以测试当前用户是否具有查看这些额外字段的适当能力的地方。您或许可以使用 current_user_can( 'csr' ) 或什至更好地向 csr 角色添加类似 manage_csr 的功能。我正在使用 manage_options 功能，因为它更容易测试。
// Add new checkout fields
function kia_filter_checkout_fields( $fields ){
if( current_user_can( 'manage_options' ) ) {
$fields['extra_fields'] = array(
'date_of_purchase' => array(
'type' => 'text',
'label' => __( 'Date of Purchase', 'your-plugin' ),
'placeholder' => _x ('MM/DD/YYYY', 'placeholder', 'your-plugin' ),

'options' => array('option-1' => __( 'Option 1', 'your-plugin' ), 'option_2' => __( 'Option 2', 'your-plugin' ), 'option_3' => __( 'Option 3', 'your-plugin' ) )

),
'product_condition' => array(

}
return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'kia_filter_checkout_fields' );
您会注意到我对您的 "Fan Stopped" 等复选框做了一些不同的事情。你不必这样做，但我很好奇和拖延。 WooCommerce 不支持多选复选框集，但它支持定义您自己的自定义字段类型。因此，我们创建了一个新的表单字段类型：
function kia_multicheck_form_field( $field, $key, $args, $value ){
$field_html = '<fieldset>';
if( isset( $args['label'] ) ){
$field_html .= '<legend>' . $args['label'] . '</legend>';
}
if ( ! empty( $args['options'] ) ) {
foreach ( $args['options'] as $option_key => $option_text ) {
$field_html .= '<input type="checkbox" class="input-multicheck ' . esc_attr( implode( ' ', $args['input_class'] ) ) . '" value="' . esc_attr( $option_key ) . '" name="' . esc_attr( $key ) . '[]" id="' . esc_attr( $args['id'] ) . '_' . esc_attr( $option_key ) . '"' . checked( $value, $option_key, false ) . ' />';
$field_html .= '<label for="' . esc_attr( $args['id'] ) . '_' . esc_attr( $option_key ) . '" class="multicheck ' . implode( ' ', $args['label_class'] ) . '">' . $option_text . '</label>';
}
}
if ( $args['description'] ) {
$field_html .= '<span class="description">' . esc_html( $args['description'] ) . '</span>';
}
$field_html .= '</fieldset>';
$container_class = esc_attr( implode( ' ', $args['class'] ) );
$container_id = esc_attr( $args['id'] ) . '_field';
$after = ! empty( $args['clear'] ) ? '<div class="clear"></div>' : '';
$field_container = '<p class="form-row %1$s" id="%2$s" data-sort="' . esc_attr( $sort ) . '">%3$s</p>';
$field = sprintf( $field_container, $container_class, $container_id, $field_html ) . $after;
return $field;
}
add_filter( 'woocommerce_form_field_multicheck', 'kia_multicheck_form_field', 10, 4 );
接下来我们在结帐页面上显示新字段....但前提是它们存在，因为回到第一个代码块，它们不会如果用户没有正确的权限，则为结帐字段数组。
// display the extra field on the checkout form
function kia_extra_checkout_fields(){
$checkout = WC()->checkout();
if( isset( $checkout->checkout_fields['extra_fields'] ) ) { ?>
<div class="extra-fields">
<h3><?php _e( 'CSR Information' ); ?></h3>
<?php
// because of this foreach, everything added to the array in the previous function will display automagically
foreach ( $checkout->checkout_fields['extra_fields'] as $key => $field ) :
woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
endforeach; ?>
</div>
<?php }
}
add_action( 'woocommerce_checkout_after_customer_details' ,'kia_extra_checkout_fields' );
现在您可能需要添加一些 CSS 以使其看起来更好，并且您需要一种方法来保存多重检查数据。您可以查看我关于如何保存其余部分的教程，也许可以自己弄清楚多重检查。
