问题描述

我正在尝试将特定类别产品的自定义字段添加到单个产品页面.我在使用条件逻辑时遇到了问题. 这是到目前为止我得到的:

I'm trying to add a custom field to the single product page for products in a specific category. I'm having problems with the conditional logic tho. This is what I've got so far:

function cfwc_create_custom_field() {

global $product;
$terms = get_the_terms( $product->get_id(), 'product_cat' );

if (in_array("tau-ende", $terms)) {
    $args = array(
    'id' => 'custom_text_field_title',
    'label' => __( 'Custom Text Field Title', 'cfwc' ),
    'class' => 'cfwc-custom-field',
    'desc_tip' => true,
    'description' => __( 'Enter the title of your custom text field.', 'ctwc' ),);
    woocommerce_wp_text_input( $args );
    }}

该功能有效,但if语句无效.有人知道我在做什么错吗?

The function works but not the if-statement. Does anyone have an idea what I'm doing wrong?

推荐答案

尝试使用以下遍历术语对象的foreach循环尝试以下操作:

Try the following instead, using a foreach loop iterating through term objects:

function cfwc_create_custom_field() {
    global $product;

    $terms = get_the_terms( $product->get_id(), 'product_cat' );

    // Loop through term objects
    foreach( $terms as $term ) {
        if ( "tau-ende" === $term->slug ) {
            woocommerce_wp_text_input( array(
                'id' => 'custom_text_field_title',
                'label' => __( 'Custom Text Field Title', 'cfwc' ),
                'class' => 'cfwc-custom-field',
                'desc_tip' => true,
                'description' => __( 'Enter the title of your custom text field.', 'ctwc' ),
            ) );
            break; // The term match, we stop the loop.
        }
    }
}

当一个术语匹配时,我们将停止循环,只有一个自定义字段……它现在应该可以工作了.

When a term match, we stop the loop to have just one custom field… It should work now.
