媒体上传（前端）中的“上传到”媒体为空

Question

请帮助我。

这是代码...。效果很好，但是在媒体库上->它们显示“上传到”为“未附加”

  add_action( 'wp_ajax_OWN_PROP_attachment_upload', 'OWN_PROP_attachment_upload' );  // only for logged in user
    add_action( 'wp_ajax_nopriv_OWN_PROP_attachment_upload', 'OWN_PROP_attachment_upload' );
    if( !function_exists( 'OWN_PROP_attachment_upload' ) ) {
        function OWN_PROP_attachment_upload( ) {

        // Check security Nonce
        $verify_nonce = $_REQUEST['verify_nonce'];
        if ( ! wp_verify_nonce( $verify_nonce, 'verify_gallery_nonce' ) ) {
            echo json_encode( array( 'success' => false , 'reason' => 'Invalid nonce!' ) );
            die;
        }

        $submitted_file = $_FILES['PROP_attachment_file'];
        $uploaded_image = wp_handle_upload( $submitted_file, array( 'test_form' => false ) );

        if ( isset( $uploaded_image['file'] ) ) {
            $file_name          =   basename( $submitted_file['name'] );
            $file_type          =   wp_check_filetype( $uploaded_image['file'] );

            // Prepare an array of post data for the attachment.
            $attachment_details = array(
                'guid'           => $uploaded_image['url'],
                'post_mime_type' => $file_type['type'],
                'post_title'     => preg_replace( '/\.[^.]+$/', '', basename( $file_name ) ),
                'post_content'   => '',
                'post_status'    => 'inherit'
            );

            $attach_id      =   wp_insert_attachment( $attachment_details, $uploaded_image['file'] );
            $attach_data    =   wp_generate_attachment_metadata( $attach_id, $uploaded_image['file'] );
            wp_update_attachment_metadata( $attach_id, $attach_data );

            $thumbnail_url = wp_get_attachment_image_src( $attach_id, 'OWN-image350_350' );
            //$fullimage_url  = wp_get_attachment_image_src( $attach_id, 'full' );
            $attachment_title = get_the_title($attach_id);
            $fullimage_url = wp_get_attachment_url( $attach_id );

            $ajax_response = array(
                'success'   => true,
                'url' => $thumbnail_url[0],
                'attachment_id'    => $attach_id,
                'full_image'    => $fullimage_url,
                'attach_title'    => $attachment_title,
            );

            echo json_encode( $ajax_response );
            die;

        } else {
            $ajax_response = array( 'success' => false, 'reason' => 'File upload failed!' );
            echo json_encode( $ajax_response );
            die;
        }



      }
    }

我不明白...从前端上传图像后，一切正常。

在媒体库上，他们显示谁上载但“上载到”的用户名是“未附加”。
