Magento 2 Product Short Description Truncate?

Question

I've migrated Magento 1 to Magento 2, In the Magento 1 site on product listing page I've truncated the length of the short description.

e.g- echo Mage::helper('core/string')->truncate($short_description, '120');

I require the same thing in Magento 2 way, how can I achieve it?

Note:- I don't want to use simple core PHP to restrict length.

Answer 1

You can truncate string in Magento-2 by below code

Inject below parameters to your class __construct

protected $filter;

public function __construct(
        \Magento\Framework\Filter\FilterManager $filter
    ) {
        $this->filter = $filter;
   }

You can truncate string by below code

$this->filter->truncate($short_description, ['length' => 120]));

Answer 2

After spending two hours approx I've done this by using a helper.

Helper Path:-

Magento\Catalog\Helper\Product\ProductList.php(I'll be overriding later so you can also).

Added Following code:-

    // Extends class \Magento\Framework\App\Helper\AbstractHelper

class ProductList extends \Magento\Framework\App\Helper\AbstractHelper
     public function __construct(
            \Magento\Framework\Filter\FilterManager $filter
          ) {
              $this->filter = $filter;
            }
                // My custom method
         public function truncateString($value, $length = 80)
            {
                return $this->filter->truncate($value, ['length' => $length]) ;
            }

// In the template file, just called custom method:-

 $this->helper('Magento\Catalog\Helper\Product\ProductList')->truncateString($short_description,120); 

Note:- I tried to do it using block but due to the time restriction i'm not able will try later. if anyone do the same via block then please share here.
