Question

我有一个Wordpress网站，正在使用重力形式和ACF字段。我在重力表格中有一个用于图像URL的ACF URL字段product_photo_copy。提交重力表时，将创建一个帖子，我想获取图像URL并将其设置为该帖子的精选图像。我正在使用以下代码：

function FeaturedImagefromUrl(){ 
          if( !empty( get_field('product_photo_copy')) ){
        $link = get_field('product_photo_copy'); 

//set as featured image
// Add Featured Image to Post
$image_url        = $link; // Define the image URL here
$image_name       = 'featured-image.png';
$upload_dir       = wp_upload_dir(); // Set upload folder
$image_data       = file_get_contents($image_url); // Get image data
$unique_file_name = wp_unique_filename( $upload_dir['path'], $image_name ); // Generate unique name
$filename         = basename( $unique_file_name ); // Create image file name

// Check folder permission and define file location
if( wp_mkdir_p( $upload_dir['path'] ) ) {
    $file = $upload_dir['path'] . '/' . $filename;
} else {
    $file = $upload_dir['basedir'] . '/' . $filename;
}

// Create the image  file on the server
file_put_contents( $file, $image_data );

// Check image file type
$wp_filetype = wp_check_filetype( $filename, null );

// Set attachment data
$attachment = array(
    'post_mime_type' => $wp_filetype['type'],
    'post_title'     => sanitize_file_name( $filename ),
    'post_content'   => '',
    'post_status'    => 'inherit'
);

// Create the attachment
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );

// Include image.php
require_once(ABSPATH . 'wp-admin/includes/image.php');

// Define attachment metadata
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );

// Assign metadata to attachment
wp_update_attachment_metadata( $attach_id, $attach_data );

// And finally assign featured image to post
set_post_thumbnail( $post_id, $attach_id );
 }

}

上面创建了特色图片。现在，我需要在创建帖子时将其连接到帖子。我不确定执行此操作的最佳方法。我尝试使用Gravity表单挂钩，但是如果我提交了2ND FORM，它只会创建特色图片。表示图片为空白，然后如果我添加新帖子，则为第一篇帖子设置特色图片-第二篇帖子为空白-直到创建第三篇帖子，等等。

add_action( 'gform_after_submission', 'set_post_content', 10, 2 );

function set_post_content( $entry, $form ) {

    //getting post
    $post = get_post( $entry['post_id'] );
    FeaturedImagefromUrl();  
    //updating post
    wp_update_post( $post );
}`

这应该和此处https://docs.gravityforms.com/gform_after_submission/一样工作。因此，引力和WordPress部分正在起作用，但是我的代码有些不正确。为什么钩子不能马上走？是否与我的代码不同步？
