我有一个wordpress多站点，我希望通过主站点（mysite.com）上传的所有图片都可以访问sub1.mysite.com 和sub2.mysite.com. 所有图像应位于一个没有子目录的文件夹中（例如：wp-content/uploads/image.jpg).我尝试了下面的函数，但我的子域图像上载到wp-content/uploads/sites/#blog_id/
function wpse_16722_upload_dir( $args ) {
$newdir = \'/\';
$args[\'path\'] = str_replace( $args[\'subdir\'], \'\', $args[\'path\'] ); //remove default subdir
$args[\'url\'] = str_replace( $args[\'subdir\'], \'\', $args[\'url\'] );
$args[\'subdir\'] = $newdir;
$args[\'path\'] .= $newdir;
$args[\'url\'] .= $newdir;
return $args;
}
add_filter( \'upload_dir\', \'wpse_16722_upload_dir\' );

这将强制将所有站点上载到wp-content/uploads 目录子目录（如year/month) 仍将存在（如果启用该设置）。
/**

function wpse_147750_upload_dir( $dirs ) {
$dirs[\'baseurl\'] = network_site_url( \'/wp-content/uploads\' );
$dirs[\'basedir\'] = ABSPATH . \'wp-content/uploads\';
$dirs[\'path\'] = $dirs[\'basedir\'] . $dirs[\'subdir\'];
$dirs[\'url\'] = $dirs[\'baseurl\'] . $dirs[\'subdir\'];
return $dirs;
}
add_filter( \'upload_dir\', \'wpse_147750_upload_dir\' );
