Hello

is there any possible way to override adminhtml block i mean if someone want to edit existing admin block then where should he write the new code? Say the store switcher code what if i want to make it a table with hyperlinks instead of drop down !!!!

adminhtml works like any other module, so to rewrite an adminhtml block, you can write your config.xml like this :

i have tried the same but it did not work for me the file i was trying to override was

Can you tell me the syntax that can be used for mycompany/adminhtml/etc/config.xml
& The Module Entry XML in etc/module Folder

try

thanks for reply but i guess you are going wrong ; the class i have to override is below

and the new Class Should be

& The Middle Code Reflects the Class you want to override the core class.

isn’t that true? So i think the new Code Should be Like

i have hoped you find yourself

Sorry still in same situation anyone can help ? :-(

i gave you the solution ...

your file Main.php have to be located in app/code/local/NsName/ModuleName/Block/Adminhtml/Permissions/User/Edit/Tab/Main.php

I tried but still not working

I am not able to override Mage_Adminhtml_Block_Permissions_User_Edit_Tab_Main class

Main.php:

class MyMods_Adminhtml_Block_Permissions_User_Edit_Tab_Main extends Mage_Adminhtml_Block_Permissions_User_Edit_Tab_Main {

public function prepareForm() {

// my code
return Mage_Adminhtml_Block_Widget_Form::_prepareForm();
}
}

I tried but still not working

I am not able to override Mage_Adminhtml_Block_Permissions_User_Edit_Tab_Main class

Main.php:

public function prepareForm() {

return Mage_Adminhtml_Block_Widget_Form::_prepareForm();
}
}

Problem seems to be with your folder structure…

Modules should be in folder app/code/local, then a folder with the module company name, then a folder with the module name & then the code folders (such as Block, etc, Model...), as user R. said

From your class name it seems you are missing the module company name folder

Hope it helps
Best regards

i’m trying the same with the api rolesedit.php to override the __construct method in that.

It not working for me.

My config file :
<?xml version="1.0"?>
<config>
<modules>
<Cmp_Test>
<version>0.1.0</version>
</Cmp_Test>
</modules>
<global>
<blocks>
<adminhtml>
<rewrite>
<api_tab_rolesedit>Cmp_Test_Block_Admihtml_Api_Tab_Main</api_tab_rolesedit>
</rewrite>
</adminhtml>
</blocks>
</global>
</config>

and my main.php:

class Cmp_Test_Block_Admihtml_Api_Tab_Main extends Mage_Adminhtml_Block_Api_Tab_Rolesedit {

public function __construct() {
parent::__construct();

$rid = Mage::app()->getRequest()->getParam(’rid’, false);

$resources = Mage::getModel(’api/roles’)->getResourcesList();

$rules_set = Mage::getResourceModel(’api/rules_collection’)->getByRoles($rid)->load();

$selrids = array();

foreach ($rules_set->getItems() as $item) {
if (array_key_exists(strtolower($item->getResource_id()), $resources) && $item->getApiPermission() == ‘allow’) {
$resources[$item->getResource_id()][’checked’] = true;
array_push($selrids, $item->getResource_id());
}
}

$this->setSelectedResources($selrids);

$this->setTemplate(’api/rolesedit.phtml’);
//->assign(’resources’, $resources);
//->assign(’checkedResources’, join(’,’, $selrids));
}
}

and module file :

<?xml version="1.0"?>
<config>
<modules>
<Cmp_Test>
<codePool>local</codePool>
<active>true</active>
</Cmp_Test>
</modules>
</config>
