			//$obj->title = $item->title;

			//echo @json_encode($obj);

			$result_product = $items;/*your mysql query here*/ 
			$array_product = array();

			    $array_product [$i]["title"]= $row_product->title;
			    $array_product [$i]["catid"]= $row_product->catid;			    
			    $array_product [$i]["link"]= JRoute::_(FlexicontentHelperRoute::getItemRoute($row_product->slug, $row_product->categoryslug, 0, $row_product));
			    FlexicontentFields::getFieldDisplay($row_product, "field15");
			    $array_product [$i]["img"]= $row_product->fields['field15']->{"display_medium_src"};
			    $i++;
			}

			//you can encode the array to json if you want to send it to an ajax call
			$json_product =  json_encode($array_product);
			echo($json_product);
			exit;
		}

Hello

Did you try enabling Joomla 's View caching

I mean conservative / progressive caching ?

it should work the same way that it work for
format=html

-- caching is done at the
display()
of the frontend controller and it does not exclude format=json from caching
so it should work

-- Flexicontent is Free but involves a big effort on our part.
Like the our support? (for a bug-free FC, despite having a long list of functions) Like the features? Like the ongoing development and future commitment to FLEXIcontent?
-- Add your voice to the FLEXIcontent JED listing with a 5-star...
