Wo werden die von WordPress hochgeladenen Dateien gespeichert?

wordpress上传的文件在哪?

WordPress默认的上传文件的目录是/wp-content/uploads,而且文件是以年月的形式组织的,虽然我们可以去掉按照年月组织的选项,或者更改存储路径,但这个设置会应用到全局,不能按照特定条件选择特定目录存储文件。

WordPress上传默认设置

有时候将不同类型的文件分门别类存储,似乎比年月目录更有意义。例如幻灯片应该存储在slides目录下,下载文件应该存储在downloads文件夹下。就说幻灯片slideshow,我比较喜欢用自定义文章类型(Custom Post Type)实现,有些幻灯片脚本比较个性,不支持绝对路径,必须用相对路径,然后用base参数设置相对于哪个文件夹,这样幻灯片必须存储在某个特定的文件夹中,年月形式显然不满足要求。所以,我们需要条件化的设置上传目录。

为Custom Post Type设置上传目录

假设我要将所有在幻灯片类型的文章中上传的文件存储到/wp-content/uploads/slides文件夹中,将下面的代码放到主题的functions.php中即可

function custom_upload_directory( $uploads ) {
    $id = $_REQUEST['post_id'];
        $parent = get_post( $id )->post_parent;
 
    if( "post-type" == get_post_type( $id ) || "post-type" == get_post_type( $parent ) ) {
        $subdir = 'slides';
        $uploads['subdir'] = $subdir;
        $uploads['path'] = $uploads['basedir'].DIRECTORY_SEPARATOR.$subdir;
        $uploads['url'] = $uploads['baseurl'].'/'.$subdir;
    }
    return $uploads;
}
add_filter( 'upload_dir', 'custom_upload_directory' );

将post-type替换成自己的自定义文章类型名称,将你要创建的子目录赋值给$subdir。

将文件保存到插件目录

下面的代码要用在插件中,文件会保存到插件目录下的uploads文件夹下。

/**
 * Change Upload Directory for Custom Post-Type
 *
 * This will change the upload directory for a custom post-type. Attachments will
 * now be uploaded to an "uploads" directory within the folder of your plugin. Make
 * sure you swap out "post-type" in the if-statement with the appropriate value...
 */
function custom_upload_directory( $args ) {
  
    $id = $_REQUEST['post_id'];
    $parent = get_post( $id )->post_parent;
  
    // Check the post-type of the current post
    if( "post-type" == get_post_type( $id ) || "post-type" == get_post_type( $parent ) ) {
        $args['path'] = plugin_dir_path(__FILE__) . "uploads";
        $args['url']  = plugin_dir_url(__FILE__) . "uploads";
        $args['basedir'] = plugin_dir_path(__FILE__) . "uploads";
        $args['baseurl'] = plugin_dir_url(__FILE__) . "uploads";
    }
    return $args;
}
add_filter( 'upload_dir', 'custom_upload_directory' );

如果要以年月形式保存,修改一下代码即可

$args['path'] = plugin_dir_path(__FILE__) . "uploads" . $args['subdir'];
$args['url']  = plugin_dir_url(__FILE__) . "uploads" . $args['subdir'];

这段代码来自 http://wordpress.stackexchange.com/questions/35657/how-to-add-more-upload-directories/

为后台管理页面设定upload_dir

用wp_editor在后台管理页面(比如用add_menu_page创建的页面)创建一个媒体上传功能,希望所有从该页面上传的文件都保存到wp-content/uploads/myfolder目录下。

由 于ajax上传是直接调用wp-admin/async_upload.php文件,只能通过post_id获取post信息,而后台管理页面并非 post,所以判断什么时候应该更改upload_dir有些麻烦。此时,可以用采用判断页面referer的方法,用wp_get_referer() 函数获取引荐url,如果正好与我们的option page url想等,就更该目录。

function custom_upload_directory( $uploads ) {
 
   if( wp_get_referer() == 'http://domain.com/wp-admin/admin.php?page=myoptionpage'){
        $subdir = 'myfolder';
        $uploads['subdir'] = $subdir;
        $uploads['path'] = $uploads['basedir'].DIRECTORY_SEPARATOR.$subdir;
        $uploads['url'] = $uploads['baseurl'].'/'.$subdir;
   }
   return $uploads;
}
add_filter( 'upload_dir', 'custom_upload_directory' );

参考信息

filter:upload_dir是在wp_upload_dir()函数中调用的

$upload_dir = wp_upload_dir();
$upload_dir now contains something like the following (if successful)
Array (
    [path] => C:\path\to\wordpress\wp-content\uploads\2010\05
    [url] => http://example.com/wp-content/uploads/2010/05
    [subdir] => /2010/05
    [basedir] => C:\path\to\wordpress\wp-content\uploads
    [baseurl] => http://example.com/wp-content/uploads
    [error] =>
)
