php – The execution operator

me — Thu, 03 Dec 2009 13:24:21 +0000

**** note the back ticks not single quote ******

executes the contents of the ticks as if you are at the terminal but as apache or whoever your web server is. this code basically
echo `whoami`; // well who is this script running as


echo `pwd`;	// think whereami

echo `mkdir test`;	// make a directory

echo `mkdir test/anothertest`;	// make a directory in the directory created

echo nl2br(`ls`);	// list what is in this directory
`touch log.txt`;	// make a text file named log.txt
$date = date("F j, Y, g:i a");

`echo $date > log.txt`;		// writes the $date to log.txt

`echo foo >> log.txt`;		// writes foo to log.txt

echo nl2br(`cat log.txt`);	// echoes what is in log.txt
echo nl2br(`tail /opt/local/apache2/logs/error_log`);	// echoes what is in the error_log

Wolf CMS – Clean uploaded file names

me — Fri, 25 Sep 2009 20:09:02 +0000

To replace spaces with underscores and then remove everything that isn’t alpha-numeric open up

wolf/plugins/file_manager.FileManagerController.php

and replace the existing upload function (approx line 259) with this.
public function upload() { $data = $_POST['upload']; $path = str_replace('..', '', $data['path']); $overwrite = isset($data['overwrite']) ? true: false;


        if (isset($_FILES)) {
			//	$file = upload_file($_FILES['upload_file']['name'], FILES_DIR.'/'.$path.'/', $_FILES['upload_file']['tmp_name'], $overwrite);

			$clean_file_name = preg_replace('/ /', '_', $_FILES['upload_file']['name'] );

			$clean_file_name = preg_replace('/[^A-Za-z0-9_.]/', '', $clean_file_name );
            $file = upload_file( $clean_file_name, FILES_DIR.'/'.$path.'/', $_FILES['upload_file']['tmp_name'], $overwrite);

if ($file === false) Flash::set('error', __('File has not been uploaded!')); } redirect(get_url('plugin/file_manager/browse/'.$path)); }
