Question

我有定制模块珠宝。管理表单中使用的选项卡在类别编辑中。下面的代码用于在管理表单中添加选项卡。它会给出致命的错误

Fatal error: Call to a member function toHtml() on a non-object in D:\wamp\www\avita\app\code\local\Mage\Adminhtml\Block\Catalog\Category\Tabs.php on line 158

以下是我的文件

1.) local/Mage/Adminhtml/Block/Catalog/Category/Tabs.php

$this->addTab('upload_prices', array(
'label'     => Mage::helper('catalog')->__('Upload prices'),
'content'   => $this->getLayout()->createBlock('jewellery/adminhtml_catalog_category_product_tab')->toHtml(),
));

        $fieldset = $form->addFieldset('category_import_prices', array('legend'=>Mage::helper('catalog')->__('Import prices')));
        $fieldset->addField('prices', 'file', array(
            'label' => Mage::helper('catalog')->__('Prices file (CSV only)'),
            'name'=> 'prices',
        ));

        return parent::_prepareForm();
    }
}

现在做什么我试过但不能添加标签??

Answer 1

问题仍然存在

$this->getLayout()->createBlock('jewellery/adminhtml_catalog_category_product_tab')->toHtml();

toHtml()以非对象方式调用，createBlock('jewellery/adminhtml_catalog_category_product_tab')无法正常工作。 createBlock()用于创建新块并将其添加到布局中。该功能有3个参数。

type 2. name 3. attributes

您已将类型指定为jewellery/adminhtml_catalog_category_product_tab。 SO magento将查找app/code/local/Subora/Jewellery/Block/Adminhtml/Catalog/Category/Product/Tab.ph‌p，并且应正确声明该文件。

接下来，您需要指定块名称。有必要。 Magento需要所有块都有唯一的名称。这里没有姓名。

下一个参数是属性。这是选择性的。您可以使用此参数设置模板。所以你可以试试这段代码。

$this->getLayout()->createBlock(
    'jewellery/adminhtml_catalog_category_product_tab',
    'jewellery.tab',
     array('template' => 'your/template.phtml') //if any
)->toHtml();

修改

首先，您需要确保您的模块是否处于活动状态。你可以通过管理员这样做。 System > Configuration > Advanced。检查你的模块在那里是否有效。

接下来是，您的布局文件位置错误。 jewellery.xml是管理员布局文件。它应位于app\design\adminhtml\default\default\layout\jewellery.xml而不是app\design\frontend\base\default\layout\jewellery.xml

致命错误：在非对象上调用成员函数toHtml（）
