我正在用wp\\u insert\\u post（）追溯性地创建一篇文章，并在上面附加一幅特色图片。我需要将图像放入与帖子发布日期相对应的文件夹中。

我在wp\\u handle\\u upload函数中使用了时间参数，它应该根据参数值将文件移动到目录中（请参见代码中的-$upload\\u date-static value for now）。但是现在，图像移动到当前的年/月文件夹，忽略$upload\\u date（例如：应该去2007/11, 转到2012/12).

    $output_dir = $uploads[\'path\'];
    new_filepath = $output_dir.\'/\'.$file;


// INSERT POST AND GET POST ID  
    $my_post_id = wp_insert_post($my_post);


// Copy image from my folder to WP Uploads
    rename($filename,$new_filepath);


// required for wp_handle_upload() to upload the file
    $upload_overrides = array( \'test_form\' => FALSE );

    $upload_date = \'2007/11\'; // Using this date for testing purposes

    $movefile = wp_handle_upload( $new_filepath, $upload_overrides, $upload_date ); 

    $wp_filetype = wp_check_filetype(basename($new_filepath), null );
    $attachment = array(
         \'post_mime_type\' => $wp_filetype[\'type\'],
         \'post_title\' => $post_title,
         \'post_content\' => $post_content,
         \'post_status\' => \'inherit\'
    );
    $attach_id = wp_insert_attachment( $attachment, $new_filepath, $my_post_id );
    $attach_data = wp_generate_attachment_metadata( $attach_id, $new_filepath );
    wp_update_attachment_metadata( $attach_id, $attach_data );


// ADD FEATURED IMAGE TO THE POST
    add_post_meta($my_post_id, \'_thumbnail_id\', $attach_id);
