无效的块类型：[名称空间] \ [模块] \块\时间轴

11

我一直在尝试向页脚添加一个块，但到目前为止，它一直在返回 Invalid block type: [Namespace]\[Module]\Block\Timeline

我到目前为止所拥有的资源也可以在这里找到：https : //github.com/sandermangel/magento2-twitterfeed

我的 layout/default.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="footer">
            <block class="[Namespace]\[Module]\Block\Timeline" name="twitterfeed-timeline" template="footer/timeline.phtml"></block>
        </referenceBlock>
    </body>
</page>

和我的积木课 vendor/[namespace]/[module]/Block/Timeline.php

namespace [Namespace]\[Module]\Block;

use Magento\Framework\View\Element\Template;

class Timeline extends Template
{

    /**
     * Timeline constructor.
     * @param Template\Context $context
     * @param array $data
     */
    public function __construct(
        Template\Context $context,
        array $data = []
    ) {
        parent::__construct($context, $data);
    }

    /**

     */
    public function getTweets()
    {
        // ---
    }
}

日志中是否有错误？

@KAndy我已经用异常日志更新了。这是错误+回溯

这意味着您的类无法加载。您是否在作曲家中注册了模块？您可以添加composer.json吗？
— 康迪2015年
@KAndy对不起您的回复。添加了composer.json。你是对的。它未能在获取一个实例Magento\Framework\View\Layout\Generator\Block::getBlockInstance，但我无法确定为什么

我use在类定义之前在块类中定义了一个。在这种\情况下，我忘记了导致错误的领导。但是由于发现并抑制了该错误，Magento\Framework\View\Layout\Generator\Block::getBlockInstance因此引发了完全不相关的错误。

简而言之：导致超出class定义的PHP错误将始终导致Invalid block type:错误

我现在也遇到了类似的问题：我忘记为某些类声明一些“使用”语句。报告的“无效块类型”与实际问题无关。我花了很长时间才弄清楚。

对我来说，当我将文件名更改为与类名和XML调用相同的名称时，它已修复。像这样：

应用程序/代码/ Rafaelcg / Smartlook /视图/前端/布局/default.xml

<referenceContainer name="after.body.start">
            <block class="Rafaelcg\Smartlook\Block\Code" name="smartlook" as="smartlook" template="smartlook.phtml"/>
 </referenceContainer>

应用程序/代码/ Rafaelcg / Smartlook /块/Code.php

<?php   

namespace Rafaelcg\Smartlook\Block;

use \Magento\Framework\View\Element\Template;

class Code extends Template

如果使用Composer包含模块，则可能是该错误的另一个可能原因：

您的可能有错误的PSR-4定义composer.json。通常，它应如下所示：

"autoload": {
    "psr-4": {
        "Namespace\\Module\\": ""
    }
}

但是，如果您的模块名称不是 Module，则您的自动加载将中断，并且不会找到任何类。在这种情况下，您需要修复模块名称并composer require namespace/module再次运行以更新中的定义composer.lock并重新生成自动加载文件。
