Use plugin after getImage() in Magento 2

Question

I want to add text after image on product list page. For that I created plugin for getImage() function of vendor/magento/module-catalog/Block/Product/AbstractProduct.php

Plugin Code:

<?php
namespace Vendor\Module\Model;
class Product extends \Magento\Catalog\Block\Product\AbstractProduct
{
 public function afterGetImage(\Magento\Catalog\Model\Product $subject, $result)
 {
 $result .= 'Testing From Plugin';
 return $result;
 }
}

But I'm getting this error:

Uncaught TypeError: Argument 2 passed to Magento\Catalog\Block\Product\AbstractProduct::__construct() must be of the type array, object given

What I am doing wrong?

• Suresh Chikani: Remove extend class and check it.
• Rahul: if I remove extended class it's shows this error Argument 1 passed to Module\Model\Product::afterGetImage() must be an instance of Magento\Catalog\Model\Product, instance of Magento\Catalog\Block\Product\ListProduct\Interceptor given,

Answer 1

It create an Issue because return type of getImage is \Magento\Catalog\Block\Product\Image and you are trying to convert into string. I think by just appending the text you can not achieve your goal.

I am not sure what is your exact goal but I can assume that you need to add additional attribute to product Image attribute so you can use it in your phtml file. For that you can print the $result->getData() in your log file you can see that number of product Image attribute. So you can add your custom attribute by appending this data.

In log file I am getting,

array (
 'image_url' => 'My Product image URL,
 'width' => '240',
 'height' => '300',
 'label' => 'test',
 'ratio' => 1.25,
 'custom_attributes' => '',
 'resized_image_width' => 135,
 'resized_image_height' => 135,
 )

You can use with aroundPlugin and check,

 public function aroundGetImage(
 \Magento\Catalog\Block\Product\AbstractProduct $subject,
 \Closure $proceed,
 \Magento\Catalog\Model\Product $product,
 $imageId,
 $attributes = []
 ) {
 $result = $proceed($product, $imageId, $attributes);
 $newStr = 'Testing From Plugin';
 return $result. $newStr;
 }
