Answer 1

Pedram, Your website URL should be

index.php?route=product/product&path=20_27&product_id=41

Here the path=20 → category_id

But your URL have not path variable because you was directly go throgh on search page or home page product listing. If you want to get category title then you want to develop code through product_id.

Here is code to Getting Category Title

product.php → controller file

$Categories = $this->model_catalog_category->getCategoryName($this->request->get['product_id']);

category.php → Model file

public function getCategoryName($product_id) {
       $query = $this->db->query("SELECT DISTINCT(cd.name),p2c.product_id,cd.category_id FROM " . DB_PREFIX . "product_to_category p2c, " . DB_PREFIX . "category_description cd WHERE p2c.product_id = '".$product_id."' AND cd.category_id = p2c.category_id AND cd.category_id != 1");    
       return $query->rows;
}

If your product select under more then one category then it will give array of result otherwise it will give one result.

Pedram, If you do not want to select product into multiple category then change following code.

product.php(Controller)

$data['category_title'] = $this->model_catalog_category->getCategoryName($this->request->get['product_id']);

category.php(Model)

public function getCategoryName($product_id) { 
$query = $this-db-query("SELECT DISTINCT(cd.name),p2c.product_id,cd.category_id FROM " . DB_PREFIX . "product_to_category p2c, " . DB_PREFIX . "category_description cd WHERE p2c.product_id = '".$product_id."' AND cd.category_id = p2c.category_id AND cd.category_id != 1");     

return $query-row;}  

product.tpl (View)

<?php echo $category_title;?>

I know late to answer but i might help others . Tested in Opencart 2.3.0.2

To Show category in Product page.

You have to edit some of the opencart files. Go to Controllors > product > product.php

Find the following line

$product_info = $this->model_catalog_product->getProduct($product_id);

As we need the category for the product list we need the product_id for each products in the list

$this->load->model('catalog/category');
$categories = $this->model_catalog_category->getCategoryName($this->request->get['product_id']); if ($categories)
                                    {
                                                           $categories_info= $this->model_catalog_category->getCategory($categories[0]['category_id']);
                                                            $data['category_title']  = $categories_info['name']; 
                                                            $data['category_text'] = "Category : ";
                                                            //print_r($categories_info['name']);
                                                           // $this->data['category_title'] = $categories_info['name'];
                                    }

Now Go to Model > Catalog > Category and you need to create a new function getCategoryName that we used in controller

  public function getCategoryName($product_id) {
                                  $query = $this->db->query("SELECT DISTINCT(cd.name),p2c.product_id,cd.category_id FROM " . DB_PREFIX . "product_to_category p2c, " . DB_PREFIX . "category_description cd WHERE p2c.product_id = '".$product_id."' AND cd.category_id = p2c.category_id AND cd.category_id != 1");    
                                                    return $query->rows;
                    }

Now go to View > theme > themename > template > product > product.tpl and add following line where you want to show category

<?php echo $category_text; ?><?php echo $category_title; ?>

Answer 4

I do something like this. If you do not want to select product into multiple categories then change the following code.

(catalog/controller/product/product.php) - path to controller file (system/storage/modification/catalog/controller/product/product.php) - path to opencart controller file

Past this code on two file our controller. I past before this line: $product_info = $this->model_catalog_product->getProduct($product_id);

Because we will already have our product id in variable:

$category_information = $this->model_catalog_category->getCategoryName($product_id);

if ($category_information) {
    $data['category_name'] = $category_information['name'];
}

(catalog/model/catalog/category.php) - path to model file

Past this code before last close sign "}". You create new function in our class of model:

public function getCategoryName($product_id) { 
$query = $this->db->query("SELECT DISTINCT(cd.name),p2c.product_id,cd.category_id FROM " . DB_PREFIX . "product_to_category p2c, " . DB_PREFIX . "category_description cd WHERE p2c.product_id = '".$product_id."' AND cd.category_id = p2c.category_id AND cd.category_id != 1");     
return $query->row;
}  

(catalog/view/theme/nameyoutheme/template/product/product.tpl) And paste this code wherever you need on product tpl. I past after <ul class="breadcrumb">...</ul> :

<?php if(isset($category_name)){ ?>
    <div class="heading-title">
        <h1><?=$category_name;?></h1>
    </div>
<?php } ?>

And that's all folks.
