如何在管理中获取当前帖子id？我想使用基于帖子ID的自定义上传目录，但我似乎无法检索它？
add_filter( \'wp_handle_upload_prefilter\', \'do_pre_upload\' );
function do_pre_upload( $file ) {
add_filter( \'upload_dir\', \'do_custom_upload_dir\' );
return $file;
}
function do_custom_upload_dir( $param ) {
global $post;
$id = 344; // HOW DO IT GET THE CURRENT POST ID
//$id = $post->ID; // DOESNT WORK DOESNT GET A VALUE?????
$parent = get_post( $id )->post_parent;
if( "client_gallery" == get_post_type( $id ) || "client_gallery" == get_post_type( $parent ) ) {
$mydir = \'/client_galleryy/\'.$post->ID.\'\';
$param[\'path\'] = $param[\'basedir\'] . $mydir;
$param[\'url\'] = $param[\'baseurl\'] . $mydir;
}
return $param;
}
UPDATE
这是我的插件的完整代码，它创建了我的自定义帖子类型，使用meta-box插件创建了一个meta-box，现在是为我的自定义帖子类型/帖子id设置上传目录的代码。我必须将上传目录的代码放在错误的位置，因为它不能确定im在我的自定义帖子类型中，它应该为帖子创建新的上传目录？

根据您的评论，听起来您只是想为您的帖子类型创建一个名为client_gallery 事实上这很直接。以下仅使用upload_dir 挂钩以实现此目的：
/**
* Modify Upload Directory Based on Post Type
*
* @param Array $dir
*
* @return Array $dir
*/
function wpse_247197( $dir ) {
$request_arr = array( \'upload-attachment\', \'editpost\', \'editedtag\' );
$request = array_change_key_case( $_REQUEST, CASE_LOWER ); // WordPress uses post_id and post_ID
$type = null;
// Are we where we want to be?
if( ! ( isset( $_REQUEST[\'action\'] ) && in_array( $_REQUEST[\'action\'], $request_arr ) ) ) {
return $dir;
}
if( isset( $request[\'post_id\'] ) ) { // Get Post ID
$id = $request[\'post_id\'];
if( isset( $request[\'post_type\'] ) ) { // Get the post type if it was passed
$type = $request[\'post_type\'];
} else { // If not passed, get post type by ID
$type = get_post_type( $id );
}
} else { // If we can\'t get a post ID return default directory
return $dir;
}
if( isset( $type, $id ) && ! empty( $type ) && ! empty( $id ) ) {
// Here we can test our type and change the directory name etc. if we really wanted to
if( \'product\' != $type ) {
return $dir;
}
$uploads = apply_filters( "{$type}_upload_directory", "{$type}/{$id}" ); // Set our uploads URL for this type
$dir[\'url\'] = path_join( $dir[\'baseurl\'], $uploads ); // Apply the URL to the directory array
$dir[\'path\'] = path_join( $dir[\'basedir\'], $uploads ); // Apply the Path to the directory array
error_log( print_r( $dir, 1 ) );
}
return $dir;
}
add_filter( \'upload_dir\', \'wpse_247197\' );
我已经对上述代码进行了大量的注释，因此如果您对其有任何疑问，可以在注释中提出。其想法是，每当用户上传到帖子类型本身时，就会直接上传到文件夹。分配预上载的附件介质时情况并非如此，一旦文件已上载且URL已设置，则移动这些文件将非常麻烦。
