错误:

由于文件 wp-content/themes/store-child/functions.php 的第 336 行出错，您的 PHP 代码更改已回滚.请修复并再次尝试保存.

未捕获的错误:在 wp-content/themes/store-child/functions.php:336 中不在对象上下文中时使用 $this堆栈跟踪:#0 wp-settings.php(528):include()#1 wp-config.php(89): require_once('/kunden/631823_...')#2 wp-load.php(37): require_once('/kunden/631823_...')#3 wp-admin/admin.php(34): require_once('/kunden/631823_...')#4 wp-admin/theme-editor.php(10

谢谢！！

解决方案

如果需要将函数添加到主题的functions.php 而不是在类中，请尝试替换:

add_filter( "woocommerce_rest_prepare_shop_order_object", array( $this, "get_product_order_image"), 10, 3 );

与:

add_filter( "woocommerce_rest_prepare_shop_order_object", "get_product_order_image", 10, 3 );

它应该可以解决您发布的错误.

The code

function get_product_order_image( $response, $object, $request ) {
 
    if( empty( $response->data ) )
        return $response;
    $order_pid= $response->data['line_items'][0]['product_id'];
     $l_w_product_meta = get_post_meta($response->data['line_items'][0]['product_id']);
    $order_imgUrl= wp_get_attachment_url( $l_w_product_meta['_thumbnail_id'][0], 'full' );

    $response->data['line_items'][0]['cover_image'] = $order_imgUrl;
 
    return $response;
} 

add_filter( "woocommerce_rest_prepare_shop_order_object", array( $this, "get_product_order_image"), 10, 3 );

The Error:

Your PHP code changes were rolled back due to an error on line 336 of file wp-content/themes/store-child/functions.php. Please fix and try saving again.

Thanks!!

解决方案

If the function needs to be added to your theme's functions.php and not inside a class, try replacing:

add_filter( "woocommerce_rest_prepare_shop_order_object", array( $this, "get_product_order_image"), 10, 3 );

with:

add_filter( "woocommerce_rest_prepare_shop_order_object", "get_product_order_image", 10, 3 );

It should resolve the error you posted.
