Search Media files

found it:

-media XYZ

is there a documentation for extending the search?

All of the search modifiers are implemented as self-contained filter callbacks. There isn’t any documentation, but you can see how the media search is implemented here.

Yes thank you. Found that yesterday in the source and wrote my own modifier in minutes. Now it pulls filelinks from our internal WebDav-School-Server… and runs the exposed URL through an authentication Proxy … great stuff!

Cheers°

Awesome! That sounds pretty cool. Glad to hear you were able to get it worked out.

Cheers,

In your Plugin:
It’s only so cool because you provided this plugin. Just had to register a recursive filesearch and paginate it. Now the teachers can link files from our webdav to certain users groups in the webpage (behind a login-gate).

Additional PHP file in webroot (works as proxy):
Then I return a URL through your plugin that runs through a PHP that determines if the requested path (actually not in any webroot) is valid and the logged in user has enough rights to download. Then I simply forward the file via PHP (open file… write to browser).

Here is the code …
I am still changing things around and I stripped the particulars of our server. Please watch out for the parts with the capital letters. Hope this helps somebody! usage: -download {query}

function bils_download_search( $results, $args ) {

	// downloadsearch doesn't need paging, so if page arg is greater than one, abort.
	// We also don't want to get files for queries less than two characters.
	if ( intval( $args['page'] ) > 1 || strlen( $args['s'] ) < 2 ) {
		wp_die( 0 );
	}

	$fileinfos = new RecursiveIteratorIterator(
	    new FilesOnlyFilter(
	        new VisibleOnlyFilter(
	            new RecursiveDirectoryIterator(
	                $PATH_TO_YOUR_FILEDIRECTORY,
	                FilesystemIterator::SKIP_DOTS
	                    | FilesystemIterator::UNIX_PATHS
	            )
	        )
	    ),
	    RecursiveIteratorIterator::LEAVES_ONLY,
	    RecursiveIteratorIterator::CATCH_GET_CHILD
	);

	foreach ($fileinfos as $pathname => $fileinfo) {
		$fpn = $fileinfos->getSubPathname();
		if (stripos($fpn , $args['s'])!==false) {
			$results[] = array(
					'title'     => '/'.$fpn,
					'permalink' => 'https://PATH-TO-YOUR-SERVER-OR.PROXY?f='.$fpn,
					'info'      => 'download',
			);
		}
	}

	return $results;
