php - Magento Admin::删除特定角色/用户的菜单项

Question

我想从特定用户角色的管理菜单中删除一个菜单项。我见过其他人通过创建虚拟覆盖来做到这一点，但这些不是基于角色。我想在不使用其中一个 .xml 文件的情况下执行此操作。例如，有没有办法做到这一点； __construct() 还是 prepareLayout？

编辑:我必须补充一点，我想禁用的部分是 CMS 中的管理层次结构项。我知道我可以只为用户角色禁用层次结构，但我需要它来保存 CMS 页面。

我用自己的 block 扩展了 Mage_Adminhtml_Block_Page_Menu。我复制了函数“_buildMenuArray()”就在我返回菜单数组之前，我检查用户中的当前登录者是否不是管理员。如果是这样;我从菜单中删除了 Hierarchy 项，并将 Page 项的值设置为 last，以便正确显示阴影。

class Xxxxx_Xxxx_Block_Adminhtml_Page_Menu extends Mage_Adminhtml_Block_Page_Menu
{
    protected function _buildMenuArray(Varien_Simplexml_Element $parent=null, $path='', $level=0)
    {
        if (is_null($parent)) {
            $parent = Mage::getSingleton('admin/config')->getAdminhtmlConfig()->getNode('menu');
        }

        $parentArr = array();
        $sortOrder = 0;
        foreach ($parent->children() as $childName => $child) {
            if (1 == $child->disabled) {
                continue;
            }

            $aclResource = 'admin/' . ($child->resource ? (string)$child->resource : $path . $childName);
            if (!$this->_checkAcl($aclResource)) {
                continue;
            }

            if ($child->depends && !$this->_checkDepends($child->depends)) {
                continue;
            }

            $menuArr = array();

            $menuArr['label'] = $this->_getHelperValue($child);

            $menuArr['sort_order'] = $child->sort_order ? (int)$child->sort_order : $sortOrder;

            if ($child->action) {
                $menuArr['url'] = $this->_url->getUrl((string)$child->action, array('_cache_secret_key' => true));
            } else {
                $menuArr['url'] = '#';
                $menuArr['click'] = 'return false';
            }

            $menuArr['active'] = ($this->getActive()==$path.$childName)
                || (strpos($this->getActive(), $path.$childName.'/')===0);

            $menuArr['level'] = $level;

            if ($child->children) {
                $menuArr['children'] = $this->_buildMenuArray($child->children, $path.$childName.'/', $level+1);
            }
            $parentArr[$childName] = $menuArr;

            $sortOrder++;
        }

        uasort($parentArr, array($this, '_sortMenu'));

        while (list($key, $value) = each($parentArr)) {
            $last = $key;
        }
        if (isset($last)) {
            $parentArr[$last]['last'] = true;
        }

        $data = $this->_isAdmin($parentArr);

        return $data;
    }

    protected function _isAdmin($data){
        $userRole = Mage::getSingleton('admin/session')->getUser()->getRole();
        $roleName = $userRole->getRoleName();
        $roleId = $userRole->getRoleId();
        if ($roleName == 'Administrators' || $roleId == 1) {
            return $data;
        } else {
            if (isset($data['hierarchy'])){
                unset($data['hierarchy']);
                $data['page']['last'] = 1;  
            }
            if (isset($data['enterprise_page']['children']['hierarchy'])){
                unset($data['enterprise_page']['children']['hierarchy']);
                $data['enterprise_page']['children']['last'] = 1;
            }
            return $data;
        }
    }
}
