have you declared the "Model_" namespace in your bootstrap

have you declared the "Model_" namespace in your bootstrap

No.

How can i do this?

gristoi · February 4, 2011

in your bootstrap try adding this:

protected function _initAutoload ()
     {
       $resourceLoader = new Zend_Loader_Autoloader_Resource();
       $resourceLoader->addResourceType('model', 'models/', 'Model_');
     }

     }

Explain this line please.

$resourceLoader->addResourceType('model', 'models/', 'Model_');

Apologies, I missed a part of code out .

Let me run you through an example of one of my autoloaders. Basically the

Zend_Loader_Autoloader_Resource()

allows you to add and manage namespaces with the with the zend autoloader. Please see the correct example below:

        $resourceLoader = new Zend_Loader_Autoloader_Resource(array('basePath' => APPLICATION_PATH, 'namespace' => ''));
        $resourceLoader->addResourceType('form', 'forms/','Form_');
        $resourceLoader->addResourceType('plugins', 'library/plugins/','Plugins_');
        $resourceLoader->addResourceType('model','models/', 'Model_');

Firstly you need to set the base path for the loader, in this case it is set to the application path, the addresourceType then takes in the arguments

 $typeOfresource,$filePath,$namespace

.

So for the model you are instructing the loader to look for classes within the models/ folder with the namespace prefix of Model_.

I hope this helps.

I'm getting this error,

Fatal error: Call to a member function addRole() on a non-object in C:\Program Files\Zend\Apache2\htdocs\site\application\models\MenuAcl.php on line 9

<?php
class Model_MenuAcl extends Zend_Acl{
public $_acl=null;
public function __construct(){		

	$onerole=new Zend_Acl_Role('user1');
	$tworole=new Zend_Acl_Role('user2');

	$this->_acl->addRole($onerole);
	$this->_acl->addRole($tworole);     

	$res1=new Zend_Acl_Resource('add');
	$res2=new Zend_Acl_Resource('edit');
	$res3=new Zend_Acl_Resource('delete');

	$this->_acl->addResource($res1);
	$this->_acl->addResource($res2);
	$this->_acl->addResource($res3);

	$this->_acl->allow($onerole,array($res1,$res2));
	$this->_acl->deny($onerole,$res3);		

}
}

gristoi · February 4, 2011

Your are extending your class off Zend_Acl so instead of

this->_acl->addRole($onerole);

try

this->addRole($onerole);

you might want to google php class inheritence

colap · February 4, 2011

Yes, now it works.

<?php
class Model_MenuAcl extends Zend_Acl{
public $_acl=null;
public function __construct(){		

	$onerole=new Zend_Acl_Role('user1');
	$tworole=new Zend_Acl_Role('user2');

	$this->addRole($onerole);
	$this->addRole($tworole);     

	$res1=new Zend_Acl_Resource('add');
	$res2=new Zend_Acl_Resource('edit');
	$res3=new Zend_Acl_Resource('delete');

	$this->addResource($res1);
	$this->addResource($res2);
	$this->addResource($res3);

	$this->allow($onerole,array($res1,$res2));
	$this->deny($onerole,$res3);		

}
}

Would you please explain this line

$resourceLoader = new Zend_Loader_Autoloader_Resource(array('basePath' => APPLICATION_PATH, 'namespace' => ''));

And if i want to put that MenuAcl.php file somewhere else then what would i have to configure/change?

gristoi · February 4, 2011

this line tells the autoloader where the starting directory is situated , in this case the

APPLICATION_PATH

. so for this it starts at the application folder:

application/

models/

MenuAcl.php

for this example the autoloader would keep parsing through the model folders sub directories looking for any classes beginning with the Model_ namespace. So if you were to move this model into another folder i.e:

application/

models/

Auth/

MenuAcl.php

then you would have to amend the classes namespace to match :

class Model_Auth_MenuAcl extends Zend_Acl
{

}

have a look at the zend documentation :

http://framework.zend.com/manual/en/zend.loader.autoloader.html

What to do if i put the MenuAcl.php file in layouts/script folder or in public folder?

gristoi · February 4, 2011

You should never really put anything besides the index page and javascript, css etc into the public folder. you are in effect making the script accesible to the public domain. One of the main fundamentals of using a framework like Zend is that you application code is kept securely out of the public reach and all required code is passed to the view(index) through the controller.

For the type of classes you are referring to (Authentication , access controll etc) you should think about moving the class into your default library folder. The library folder path is already included in the default zend framework structure. So below is an example of creating a plugins folder to house it.

application/

docs/

library/

Plugins/

Auth/

MenuAcl.php

so all you would need to add in your bootstrap would be:

        $resourceLoader = new Zend_Loader_Autoloader_Resource(array('basePath' => APPLICATION_PATH, 'namespace' => ''));
        $resourceLoader->addResourceType('plugins', 'library/plugins/','Plugins_');

and chage your class name to

class Plugins_Auth_Acl extends  Zend_Acl
{
// code here
}
