Add Review Microdata to product

[rodriciru]

Currently, there's no schema markup for review.
Google complains about it, so this PR fixed that.

[Hlavtox]

I think we removed it some time ago. The review data should be put in the header, is not the case?

[rodriciru]

In that case I'm ok, but for me there's no review in any part of the page...

[rodriciru]

Sorry.
There's an AggregateRating (not in my theme), but not the reviews (in classic and hummingbird)

[rodriciru]

I made a PR long time ago to expose reviews to use in header. This involves the modification of the template, but it is still open...
Maybe its outdated now...
#140

Hi @rodriciru

I think it is not needed anymore, as we should have reviews info in JSON-LD :)

[rodriciru]

Great. But as for the moment, there's no such info (not even in the JSON_LD) this fix that for all templates that use this module.
Or we can look at other PR that adds this info to be used in the JSON-LD #140

@Hlavtox @kpodemski @rodriciru How can we move forward? Looks like discussion is stuck on a disagreement

[Hlavtox]

I will summarize.

• In https://github.com/PrestaShop/classic-theme/blob/develop/templates/_partials/microdata/product-jsonld.tpl, there is a rating microdata provided in a limited form.
• I agree that adding more structured data is always good.
• We removed all inline microdata in previous versions of Prestashop, it's not good to clutter the code with them. They should be in the header.
• So, can we use displayHeader for this purpose @rodriciru?

I'm not a PrestaShop dev, so my understanding of PrestaShop is limited. Anyway, I do my best

Anyway, if has such info in microdata is a problem, we can close this PR and look to this PR #140 which populates comments, and reviews, so every template can make use of it in the way the want

This pull request is no longer relevant and hasn't received any updates in a long time. Furthermore, schema.org requires a different approach (schema data in the header, not inline). Therefore, I'm closing this pull request.
