Re: Vendors php classes for cake 2.1

Hi,

thx for your instructions.

I just tried it (cake 2.2) and found that the App::import in the constructor of the wapper class does not get executed for some reason.
Actually the constructor doesn't seem to get executed at all?

As soon as I move all code from the constructor into the domfromfile function, the wrapper works.
However, I would prefer using the constructor. Do you have an idea what might be wrong?

Cheers!
Jens

For starters

App::import() is the right way to include vendor files

App::uses() should mainly be used with cake and app stuff

The main difference:

import() usually works like include/require and will load this file right away

uses() will only store the information where to find that file and the lazy loading will fetch this file only if needed

I always try to avoid App::import() and vendor loading directly inside the application.

Wrapping those third party classes in a Lib layer has several advantages.

a) you can easily work with App::uses() internally in the app

b) you can override some methods/settings if they don't make sense

c) changes in how those foreign classes are used/called on updates doesn't have to effect your app

d) makes use of the lazyloading from above

e) it is much easier to test

example: simle_html_dom

in /Lib/Utility/HtmlDomLib.php:

class HtmlDomLib {

public function __construct() {

$res = App::import('Vendor', 'SimpleHtmlDom', array('file'=>'simple_html_dom/simple_html_dom.php'));

if ($res === false) {

trigger_error('simplehtmldom lib not found');

}

}

/**

* @param url or path to file content

* @return object Dom

* 2010-11-06 ms

*/

public static function domFromFile($url) {

return file_get_html($url);

}

}

anywhere in your application:

App::uses('HtmlDomLib', 'Utility');

$DomObject = HtmlDomLib::domFromFile($url);

happy coding

What is for you the best way to implement any external php class to be avaible trough controllers or models?
We truly need to package any php class in a plugin?? And how? (cake 2.1)
