Show images for the sub-categories in the opencart versions 2.3, 3, and 4

This Opencart tip is to show images for the sub-categories in the Opencart version 2.3, but you can make changes as per the following instructions.

Opencart 2.3

Find the following code at catalog\controller\product\category.php

$data['categories'][] = array(
	'name' => $result['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
	'href' => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url)
);

Replace the code with the below code:

$data['categories'][] = array(
	'name' => $result['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
	'image' => $this->model_tool_image->resize($result['image'], 100,100),
	'href' => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url)
);

Changed is 'image' => $this->model_tool_image->resize($result['image'], 100,100), if you have to increase the size then change 100 to other values.

Find the following code at catalog\view\theme\default\template\product\category.tpl

Replace with the below code

Extra code added is below and there are two places to add the code:

You are set for the default theme, but if you are using a custom theme then you have to manage as per your theme.

Opencart 3 and Opencart 4

Find the following code at catalog\controller\product\category.php

$data['categories'][] = array(
	'name' => $result['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
	'href' => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url)
);

Replace the code with the below code:

$data['categories'][] = array(
	'name' => $result['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
	'image' => $this->model_tool_image->resize($result['image'], 100,100),
	'href' => $this->url->link('product/category', 'path=' . $this->request->get['path'] . '_' . $result['category_id'] . $url)
);

Changed is 'image' => $this->model_tool_image->resize($result['image'], 100,100), if you have to increase the size then change 100 to other values.

Find the following code at catalog\view\theme\template\product\category.twig

{% if categories|length <= 5 %}
          

            

              

                {% for category in categories %}
                  

                  {{ category.name }}
                  
                {% endfor %}
              
            
          
        {% else %}
          

            {% for category in categories|batch((categories|length / 4)|round(1, 'ceil')) %}
              

                

                  {% for child in category %}
                    
{{ child.name }}
                  {% endfor %}
                
              
            {% endfor %}
          
          

        {% endif %}

Replace with the following:

{% if categories|length <= 5 %}
          

            

              

                {% for category in categories %}
                  

                  {% if category.image %}
                    

                      
                    
                  {% endif %}
                  {{ category.name }}
                  
                  
                {% endfor %}
              
            
          
{% else %}
          

            {% for category in categories|batch((categories|length / 4)|round(1, 'ceil')) %}
              

                

                  {% for child in category %}
                    

                    {% if child.image %}
                      

                        
                      
                    {% endif %}
                    {{ child.name }}
                    
                    
                  {% endfor %}
                
              
            {% endfor %}
          
          

{% endif %}

The following are codes added in the above

{% if category.image %}
          

                      
          
{% endif %}

And

{% if child.image %}
       

               
        
{% endif %}

With the above changes now you can see images for the sub-categories, for example:

By changing like above code, you can show images for the sub-categories on the category page of Opencart
