Magento自定义管理模块为空 [英] Magento custom admin module is blank

问题描述

我已经创建了一个自定义管理模块，但是我无法在其中添加内容，它始终为空白 我正在尝试使用简单的代码进行测试，但似乎无济于事

I've create a custom admin module but i can't put a content in it, it always is blank i'm trying with a simple code for test, but nothing seem to work

public function indexAction()
{
    $this->loadLayout();

    $this->_addContent($this->getLayout()->createBlock('adminhtml/template')->setTemplate('uhmaadmin/contactos.list.phtml')->toHtml());
    $this->renderLayout();
}

.phtml中的

an in the .phtml

echo 'hello world';

但不输出任何内容，如果phtml中出现错误，系统崩溃，则意味着它正在获取文件，但是，我想念的是 请帮助

but doesn't print nothing, if a make an error in the phtml, the system crash, it means that its getting the file, but, what i'm i missing please, help

推荐答案

管理控制器上的$this->_addContent方法希望传递给块对象.

The $this->_addContent method on an admin controller expects to be passed a block object.

protected function _addContent(Mage_Core_Block_Abstract $block)
{
    $this->getLayout()->getBlock('content')->append($block);
    return $this;
}

您正在传递

$this->getLayout()->createBlock('adminhtml/template')->setTemplate('uhmaadmin/contactos.list.phtml')->toHtml()

这是一个字符串.您渲染得太早了.如果检查日志，应该会看到警告/错误/提示，表明_addContent的参数是意外类型.

which is a string. You're rendering it too soon. If you check your logs you should see a warning/error/something telling you that the argument to _addContent is an unexpected type.

尝试不使用toHtml方法调用

Try it without the toHtml method call

$this->_addContent($this->getLayout()->createBlock('adminhtml/template')->setTemplate('uhmaadmin/contactos.list.phtml'));
