I’m developing a website under Zend Framework 1.12 where users can upload pictures to illustrate their profile.
I’m trying to implement a function that will check, every time a miniature is displayed, if it exists and save it in different sizes if not (the objective is to accelerate browsing by reducing HTTP request size):
- The registered user upload his full size original picture (e.g. 2400 x 2400px 1MB)
- The picture is saved in a folder named USER_SIZE on the server
- Other users navigate on the website:
- home page or any other page
- page with the list of users where I want to display 50x50 miniature for each user
- detailed user profile where I want to display a 100x100 miniature picture
To do this I was hoping to use a customized router that would transform picture URL and automatically will scale / crop and save the miniatures if it doesn’t already exists.
Public page (the view) :
<html>
<body>
...
<img src="<?php echo $this->url(array("method" => "scale", "params" => "50x50", "filename" => $userFileName), "image")">
...
</body>
</html>
Custom route :
<?php
require_once 'Zend/Controller/Router/Route/Abstract.php';
Class Application_Controllers_Route_Image extends Zend_Controller_Router_Route_Abstract
{
public static function getInstance(Zend_Config $config)
{
return new self($config->route);
}
// NOT WORKING
public function match($path)
{
// Check if the URL is a miniature picture URL
if (preg_match("#miniatures/([^/]+)/([^/]*)/(.+)#"){
// resize picture and save miniature
...
}
}
// WORKING
public function assemble($data = array)
{
// Return a new path name for the miniature that should have been
// resized and saved in a different folder for which the name is constructed
// with params used in the view
return sprint("miniatures/%s/%s/%s", $data["method"], $data["params"], $data["filename"]
}
}
Of course all this code is very simplified. I have been able to make the custom route work to generate the miniature URL and receive something like miniatures/scale/50x50/userpicture.jpg as a result of the match function. However, I’m totally unable to capture the call to the router in the match function. This is very poorly documented in Zend documentation and I didn’t find any ideas with Google or StackExchange.
Do you know when and how the match function is called in the workflow? Does anybody has done something similar that could help?
