Question

我正在学习Magento模块开发。我正在尝试为Magento Admin面板开发自定义模块。我想显示网格。我的代码如下

位置：app / etc / modules

Digitab_Brandlogo.xml

<?xml version="1.0" encoding="utf-8"?>
<config>
    <modules>
        <Digitab_Brandlogo>
            <active>true</active>
            <codePool>local</codePool>
        </Digitab_Brandlogo>
    </modules>
</config>

位置：app / code / local / Digitab / Brandlogo / Block / Adminhtml

Brandlogo.php

<?php
    class Digitab_Brandlogo_Block_Adminhtml_Brandlogo extends Mage_Adminhtml_Block_Widget_Grid_Container
    {
        public function __construct()
        {
                $this->_controller = 'adminhtml_brandlogo';
                $this->_blockGroup = 'brandlogo';
                $this->_headerText = Mage::helper('digitab_brandlogo')->__('Brand Logo Manager');
            $this->_addButtonLabel = Mage::helper('digitab_brandlogo')->__('Add Brand');
                parent::__construct();
        } 

       protected function _prepareLayout()
       {
          $this->setChild('grid',$this->getLayout()->createBlock( $this->_blockGroup.'/' . $this->_controller . '_grid',    $this->_controller . '.grid')->setSaveParametersInSession(true) );
          return parent::_prepareLayout();
       }
    }

        return parent::_prepareCollection();
    }

    public function getRowUrl($row)
    {
        return $this->getUrl('digitab_brandlogo_admin/brandlogo/edit',array('id' => $row->getId()));
    } 


    protected function _prepareColumns()
    {
        $this->addColumn('brand_id', array(
            'header' => $this->_getHelper()->__('brand_id'),
            'type' => 'number',
            'index' => 'brand_id',
        ));


         $this->addColumn('brand_name',
            array(
                'header'=> $this->__('brand_name'),
                'index' => 'brand_name'

我在 exception.log 中发现的错误如下所示

exception 'Mage_Core_Exception' with message 'Invalid block type: Digitab_Brandlogo_Block_Brandlogo' in /home3/theaid/public_html/demo/app/Mage.php:595

当我点击Digitab的Brandlogo菜单时，我得到一个空白的白页。

有人可以帮我显示网格吗？

谢谢

Answer 1

1.在app / code / local / Digitab / Brandlogo / Block / Adminhtml / Brandlogo.php

中使用方式错误

像这样使用

$this->_headerText = Mage::helper('digitab_brandlogo')->__('Brand Logo Manager');

而不是

$this->_headerText = Mage::helper('brandlogo')->__('Brand Logo Manager');

您没有任何资源设置文件

在Magento的管理模块中显示网格
