exit(); is your problem. This halts all further php-execution.
The way I do this is: the controller assembles the path to the image. the view contains the readfile() and some header adjustments. (no blank lines or forgotten spaces outside the php-tag) a blank layout, also with no extra whitespace that could break the image. Other good tips on the subject: I like to make the URL contain the filename, or A filename anyway just to get an extention which helps some browsers. http://app.site/controller/action/id/filename.jpg Files should have a size: header("Content-Length: " . filesize($filePath)); Some headers for making the file download: header("Content-Description: File Transfer"); header("Content-Type: application/octet-stream"); header("Accept-Ranges: bytes"); header("Content-Disposition: attachment; filename=" . $filename . ";"); header("Content-Transfer-Encoding: binary"); You may also want to set some cache-headers. If your images or other files are large you may want to save some server-RAM by using the function readfile_chunked(). It can be found in the comments for readfile on php.net but here it is if you want: function readfile_chunked($filename,$retbytes=true) { $chunksize = 1*(1024*1024); // how many bytes per chunk $buffer = ''; $cnt =0; // $handle = fopen($filename, 'rb'); $handle = fopen($filename, 'rb'); if ($handle === false) { return false; } set_time_limit(0); while (!feof($handle)) { $buffer = fread($handle, $chunksize); echo $buffer; ob_flush(); flush(); if ($retbytes) { $cnt += strlen($buffer); } } $status = fclose($handle); if ($retbytes && $status) { return $cnt; // return num. bytes delivered like readfile() does. } return $status; } On Dec 17, 10:04 am, krr <[EMAIL PROTECTED]> wrote: > A part of my application has display of images, and the images are not > under webroot, but protected, so that only looged in users can view > the images. > > In my old plain php application, php script was checking for login and > doing a readfile($image_file_path); and I was using it as below > > <a href="/scripts/getimage?name=abcd.jpg"> > > I am trying to migrate the app to cakephp, and I don't know how to > emulate the samething in cakephp.
