问题
I would kindly ask all of you if you could help me. I'm working in zend framework and I need to adjust my code so, when a user drops the file in the browser(before the actual upload), the file name and extension is checked in a sense if it already exists. Depending on the existence of the ifle, an icon right by the trash icon will appear (green tick if fresh upload, no other file with the same name. Red cross if there is a file).
But to address a matter that is more important to me, and that is for me to set up the code in a manner so when uploading depending on the file name and file extension, the file is being uploaded in a specific folder. So e.g. an X.png, gets into a "png" folder - subfolder "X", and Y.pdf gets into a "pdf" folder - subfolder "Y"
Here is my code do far...
This is the application.js and the jquery.fileupload-ui.js. (javascript) http://pastebin.com/eqpK1KmX
This is the index.phtml and the layout of the index.phtml (view) http://pastebin.com/mh5jnLju
InterfaceController.php (controller):
<?php

realpath(APPLICATION_PATH . '/models'),
realpath(APPLICATION_PATH . '/../library'),
get_include_path(),
)));
}
public function indexAction()
{
}
public function mediaAction()
{
$this->_helper->layout()->setLayout('media');
}
public function checkFile(){
//isn't doing anything at all, just my start of thinking in a way of
//sloving this
}
function uploadjqAction()
{
$this->_helper->layout()->setLayout('media');
Zend_Loader::loadClass('Upload',
array(
APPLICATION_PATH.'/modules/design/models/vendors'

If anyone is willing to help, I would be very very grateful, I know it a lot of work, I'm a noob and I need all the help I can get.
Thank you in advance! and please don't get mad at me.
回答1:
A few general comments.
Typically, the include_path setting is done at Bootstrap, not in the controller.
I would clearly separate in my mind what happens on the server side and what happens on the client side.
First, think of it first as a standard form submission. The form has a file element, the user browses his file system to select his file. He clicks submit. It either succeeds or fails. All the dragging and dropping and changing icons is pure client-side candy to be added after you have the core functionality in place.
So, I would create a form that has a standard file element. To that element, I would attach a custom validator that performs your specific directory/filename checks. In the event of a valid submission, you employ a model/service that moves the file to the right place, writes your db records, etc.
Then I would layer on some AJAX handling. Client-side script intercepts the form's submit event and you use an AjaxContext action helper on the server side to send back JSON responses. These responses are handled by client-side code that renders your ok/fail icons.
Finally, I would layer on the client-side drag/drop functionality to trigger the submit event.
The benefits:
- It clearly delineate server-side and client-side issues.
- It breaks the overall job into a targeted collection of well-defined tasks.
- Progressive enhancement/graceful degradation.
- Seems more consistent with the ZF way of handling form submissions in controllers (create form with validators, check isValid(), process successful submission).
I recognize that this is only broad brush-strokes, but I hope it helps to clarify some thinking.
