Plugin class ...\DirectoryDataProcessorPlugin doesn't exist

Question

I'm trying to create a plugin for DirectoryDataProcessor.php but I can't seem to get the di.xml to work. The LayoutProcessor in di.xml works.

I get the following error:

Plugin class BB\Checkout\Plugin\Block\DirectoryDataProcessorPlugin doesn't exist.

etc/di.xml

<?xml version="1.0"?>
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
    <plugin name="bb_checkout" type="BB\Checkout\Plugin\Block\LayoutProcessor" sortOrder="1"/>
 </type>

<type name="Magento\Checkout\Block\Checkout\DirectoryDataProcessor">
    <plugin name='bb_checkout_req' 
 type='BB\Checkout\Plugin\Block\DirectoryDataProcessorPlugin' 
 sortOrder='99'/>
</type>

/BB/Checkout/Plugin/Block/DirectoryDataProcessorPlugin.php

<?php

 namespace BB\Checkout\Plugin\Block\Checkout;

 class DirectoryDataProcessorPlugin
 {
/**
 * @param \Magento\Checkout\Block\Checkout\DirectoryDataProcessor $subject
 * @param array $jsLayout
 * @return array
 */
public function afterProcess(
    \Magento\Checkout\Block\Checkout\DirectoryDataProcessor $subject,
    array  $jsLayout
) {

    return $jsLayout;
}
}

I tried changing the name and folder structure many times and have no clue on how to fix this. I just started working with Magento 2.

I also tried putting DirectoryDataProcessorPlugin in plugin/block instead of plugin/block/checkout.

Answer 1

You are misplacing your file

In di.xml you have defined

type='BB\Checkout\Plugin\Block\DirectoryDataProcessorPlugin'

where as you have shown the directory path of your file as

/BB/Checkout/Plugin/Block/Checkout/DirectoryDataProcessorPlugin.php

Move your file out of Checkout directory and check.

Answer 2

Replace your etc/di.xml code with following code.

<?xml version="1.0"?>
 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
   <type name="Magento\Checkout\Block\Checkout\LayoutProcessor">
    <plugin name="bb_checkout" type="BB\Checkout\Plugin\Block\LayoutProcessor" sortOrder="1"/>
 </type>

<type name="Magento\Checkout\Block\Checkout\DirectoryDataProcessor">
    <plugin name='bb_checkout_req' 
 type='BB\Checkout\Plugin\Block\Checkout\DirectoryDataProcessorPlugin' 
 sortOrder='99'/>
</type>

You missed Checkout on above XML it should be like BB\Checkout\Plugin\Block\Checkout\DirectoryDataProcessorPlugin.

After replacing with above code if it's still not working that I'll suggest you to check the file permission.

Hope it'll help you.
