small update to schema.org snippets.php

alxgan · August 26, 2024, 12:01:45 PM

Hello,
Here is a small update to snippets.php
I wanted to add the schema org in the <head> of the webpage, as I read it in the guideline; so I did some modification to snippets.php to make it more "organized".
Please see attached file. You have to change extension from txt to php or copy-paste the code below.
Better to add it to your template folder: templates\template_name\html\com_virtuemart\sublayouts so it won't be overwritten on update.
The reviews are incomplete but when I will have some review data array example, I will update it.

Code Select

Hi
just to let you know that

Code Select

$priceUntil = '2030-12-31'; //Valid for a lond timeIs not valid for prices products, as google accept one year at max.
By my side I use

Code Select

$datevalid = gmDate("Y-m-t");To just keep the price valid by the end of each months.

News:

small update to schema.org snippets.php
