I’m developing a website using WordPress as my Framework. The templates are highly customized and really doesn’t use much of WordPress’s features. I just use it for registering users and publish a few articles here and there.
One of the templates is a product template. In this template I retrieve product information based on product ID sent in the URL.
What I want to do, is to take info from this product and add it to my <meta> tags.
According to WordPress documentation, headers are loaded before templates.
So, how can I add meta tag information based on data loaded in my template?
Do I have to query the database “a second time” in the header in order to retrieve the data wanted?
I know WordPress has some functionality for this, since article titles can be retrieved in the header file. But I’m not sure how I can take advantage of this.
Even though header is loaded before template, few global variable are available even before header is loaded and
$postis one of them which hold post data + metadata.So you can access post meta in header as well.
