我已经在functions.php上有了此代码

该代码将在每个产品变体上添加一个新字段,以具有日期时间输入字段,因此,当当前日期超过输入日期时,变体将自动过期.

// Add Variation Settings
add_action( 'woocommerce_product_after_variable_attributes', 'variation_settings_fields', 10, 3 );

// Save Variation Settings
add_action( 'woocommerce_save_product_variation', 'save_variation_settings_fields', 10, 2 );

//Create New fields for Variations
function variation_settings_fields( $loop, $variation_data, $variation ) {
    // Text Field
    woocommerce_wp_text_input( 
        array( 
            'id'          => '_text_field_date_expire[' . $variation->ID . ']',
            'class'       => '_text_field_date_expire',
            'type'        => 'datetime-local',  
            'label'       => __( 'Date of Expiration', 'woocommerce' ), 
            'placeholder' => '',
            'desc_tip'    => 'true',
            'description' => __( 'Expiration of Each Product Variation', 'woocommerce' ),
            'value'       => get_post_meta( $variation->ID, '_text_field_date_expire', true )
        )
    );
}


//Save New Fields for Variation
function save_variation_settings_fields( $post_id ) {
    // Text Field
    $text_field = $_POST['_text_field_date_expire'][ $post_id ];
    if( ! empty( $text_field ) ) {
        update_post_meta( $post_id, '_text_field_date_expire', esc_attr( $text_field ) );
    }
}

这是在Wocommerce的每个变体上添加一个新字段.

我想做的是获取每个“ _text_field_date_expire”元,以便为每个产品删除过期的版本.

我如何在functions.php上获取每个woocommerce变体ID,以便可以添加一条规则,即当它已经超过当前日期时,它将过期？

var_dump(get_post_meta( $variation_id , '_text_field_date_expire', true ));

这段代码是我将用来获取datetime字段的代码,但是不确定如何获取每个$variation_id字段吗？

谢谢！

解决方法:

试试这个：

$args = array(
    'post_type'     => 'product_variation',
    'post_status'   => array( 'private', 'publish' ),
    'numberposts'   => -1,
    'orderby'       => 'menu_order',
    'order'         => 'asc',
    'post_parent'   => get_the_ID() // get parent post-ID
);
$variations = get_posts( $args );

foreach ( $variations as $variation ) {

    // get variation ID
    $variation_ID = $variation->ID;

    // get variations meta
    $product_variation = new WC_Product_Variation( $variation_ID );

    // get variation featured image
    $variation_image = $product_variation->get_image();

    // get variation price
    $variation_price = $product_variation->get_price_html();

    get_post_meta( $variation_ID , '_text_field_date_expire', true );

}
