A full-blown AJAX file uploader plugin for CakePHP 2.0.x and 2.1. Using this, you can add multiple file upload behaviour to any or all of your models without having to modify the database or schema.
You can click on the Upload File button, or drag-and-drop files into it. You can upload multiple files at a time without having to click on any button, and it shows you a nice progress notification during uploads. You can also delete files in edit mode.
As of May 2015, this now uses Dropzone.js to allow file uploads.
You can either download the ZIP file: https://github.com/srs81/CakePHP-AjaxMultiUpload/zipball/master
or checkout the code (leave the Password field blank):
git clone https://srs81@github.com/srs81/CakePHP-AjaxMultiUpload.gitUnzip or move the contents of this to "Plugin/AjaxMultiUpload" under the app root.
Open Config/bootstrap.php and add this line:
CakePlugin::load('AjaxMultiUpload', array('bootstrap' => true));This will allow the plugin to load all the files that it needs including it's own bootstrap.
Make sure to create the correct files upload directory if it doesn't exist already:
cd cake-app-root mkdir webroot/files chmod -R 777 webroot/files
The default upload directory is "files" under /webroot - but this can be changed (see FAQ below.)
You don't have to give it a 777 permission - just make sure the web server user can write to this directory.
Add to Controller/AppController.php for use in all controllers, or in just your specific controller where you will use it as below:
public $components = array('Session', 'AjaxMultiUpload.Upload');The component will load the required helper automatically so you don't have to manually load it in your controllers.
Let's say you had a "companies" table with a "id" primary key.
Add this to your View/Companies/view.ctp:
echo $this->Upload->view('Company', $company['Company']['id']);and this to your View/Companies/edit.ctp:
echo $this->Upload->edit('Company', $this->Form->fields['Company.id']);If you don't like the custom views that result from this->Upload->view(), you can use the listing() function to custom-list files, or use the file listing for other purposes (generating thumbnails, for instance).
In your view, you can do this:
$results = $this->Upload->listing ($model, $id);
$directory = $results['directory'];
$baseUrl = $results['baseUrl'];
$files = $results['files'];
foreach ($files as $file) {
$f = basename($file);
$url = $baseUrl . "/$f";
echo "<a href='$url'>" . $f . "</a><br />\n";
}and use the directory, baseUrl, and files data structures to display your files. Look at UploadHelper's view() function to see how the listing() function is used internally.
Add the following to the delete() function of your Company controller where appropriate (either first line, or right after $this->Company->delete() check):
echo $this->Upload->deleteAll('Company', $id);Add a third parameter to the this->Upload->edit() function, which specifies which types you want to restrict the upload to.
echo $this->Upload->edit('Company', $this->Form->fields['Company.id'], "audio/*,image/*,.psd,.pdf");If you don't specify the third parameter, users will be able to upload all file types (so all files types are allowed by default.)
Documentation on the string to use to specify files / types to upload is in this Stackoverflow answer about Dropzone allowed types: http://stackoverflow.com/a/17275873
Thanks to rscherf@github for the following two fixes.
If you are using Auth (either the CakePHP core Auth or some of the compatible or incompatible ones), you need to modify the controller to allow uploads to work.
Add these lines to the UploadsController.php (you may have to modify slightly depending on your Auth setup). Thanks to @notoriousturtle for the fix for CakePHP 2.5 and above.
public function beforeFilter() {
parent::beforeFilter();
// Need to disable Security component
$this->Security->unlockedActions = array('upload');
}public function isAuthorized() {
return true;
}
public function beforeFilter() {
$this->Auth->allow(array('upload','delete'));
}If you are using a subdomain, you will have to set up the plugin correctly to work (depending, again, on how you have your sub-domains set up in your Apache/htaccess settings).
These are the changes to be made to routes.php:
// AJAX Multi Upload plugin
Router::connect('/:subdomain/ajax_multi_upload/:controller', array('plugin' => 'ajax_multi_upload'), $ops);
Router::connect('/:subdomain/ajax_multi_upload/:controller/:action/*', array('plugin' => 'ajax_multi_upload'), $ops);Nope. :) Just drop this plugin in the right Plugin/ directory and add the code to the controller and views. Make sure the "files" directory under webroot is writable, otherwise uploads will fail.
No tables/database changes are needed since the plugin uses a directory structure based on the model name and id to save the appropriate files for the model.
The default upload file size limit is set to a conservative 2 MB to make sure it works on all (including shared) hosting. To change this:
Are you stuck to the "files" directory under webroot? Nope.
Open up Config/bootstrap.php under the Plugin/AjaxMultiUpload directory and change the "AMU.directory" setting.
The directory will live under the app webroot directory - this is as per CakePHP conventions.
By default, the plugin stores files into /webroot/files/$model/$id . It is possible to change the /files/ directory through the configuration setting mentioned above. To change the /$model/$id/ path though (say you want to change it to md5($model . $id)), look for this line in Controller/Component/UploadComponent.php AND View/Helper/UploadHelper.php:
public function last_dir ($model, $id) {Change the function in both these files to do whatever you would like. Note that you have to make the changes in BOTH files for this to work.
It is now possible to have multiple view/edit functions in the same CakePHP view. For example, for a Photo controller, add this to your view.ctp:
echo $this->Upload->view('Photo', "thumbs/" . $photo['Photo']['id']);
echo $this->Upload->view('Photo', "highres/" . $photo['Photo']['id']);and this to your View/Photos/edit.ctp:
echo $this->Upload->edit('Photo', "thumbs/" . $this->Form->fields['Photo.id']);
echo $this->Upload->edit('Photo', "highres/" . $this->Form->fields['Photo.id']);This allows you to upload and two sets of files to your same entity/object in a controller/view.
This uses the Dropzone.js Javascript library for file uploads: http://www.dropzonejs.com/ and file icons from: http://www.splitbrain.org/projects/file_icons . (The plugin previously used an Ajax Upload script from: http://valums.com/ajax-upload/)
