Hide the price if it is empty or zero OpenCart

A simple modification that will allow you to hide the price of the product if it is empty or equal to 0.

If you leave the "price" field empty, then "0" will be displayed on the site by default - the module solves this problem - it forces you not to display a zero price. That is, if the product is free or the price of the product is not defined or by agreement, you can simply hide it.

If the price is zero or not specified, it is hidden: in the product card, in the category, in the manufacturers, in the search, in promotions, in standard modules.
