Adding 'Schema.org' Mark-up

Good to hear from you again, and thanks for this question. I want to make sure I understand what you’re asking for. As I understand it, you want to replace the default [+link+] value with something like the example you give at the end of your post; is that right?

Assuming that’s the idea, you need to replace three values that are different for each gallery and/or item:

1. “/gallery-link-page/” – is this a link to the page in which the [mla_gallery] appears?
2. “images/thumbnail-1.jpg” – this looks like the thumbnail image for the attachment; right?
3. “Name of Gallery” – is this the title of the page in which the [mla_gallery] appears?

If the link and name are for a page/post that’s different from the “current” page/post, i.e., the one that contains the [mla_gallery] shortcode, then you need some way to specify which page/post you want to link to. How would that work?

In the current MLA version you can get access to some information about the attachment’s “parent” page/post, but there’s no access to information about the post/page on which the shortcode appears. That’s an interesting idea for a future enhancement.

In the interim, you can probably solve the problem by adding some code to the filters provided by [mla_gallery]. Let me know if that would work for you.

If I can get a bit more information I can be more helpful. Let me know the answers to the above questions and I’ll work on it. Thanks!

Yes, but I’m not concerned about the last one. I just copied my “Scema Template” as a reference.

“/gallery-link-page/” – is this a link to the page in which the [mla_gallery] appears?
“images/thumbnail-1.jpg” – this looks like the thumbnail image for the attachment; right?
“Name of Gallery” – is this the title of the page in which the [mla_gallery] appears?

This will be the “standard” gallery page. As an example: https://sandbox.imagesinthebackcountry.com/portfolio/portfolio-landscape/yosemite-portfolio/. I still have admin access if need be.

If the link and name are for a page/post that’s different from the “current” page/post, i.e., the one that contains the [mla_gallery] shortcode, then you need some way to specify which page/post you want to link to. How would that work?

It isn’t a pressing thing. I’m in the process of re-designing my photography site. The new theme/template adds ‘Schema.org’, at least some of it, so I thought I’d try and add it. Also trying to figure out ‘rewrites’ too, but that’s for another day/post. ??

I had a look at your site and the example page you gave above. Essentially, all you want to do is add the itemprop="contenturl" and itemprop="thumbnailurl" attributes to your link and image tags.

There are two ways to do that. First you could add mla_link_attributes='itemprop="contentURL"' and mla_image_attributes='itemprop="thumbnailUrl"' to your [mla_gallery] shortcodes. That’s great for changing the links on a case-by-case basis but it’s painful to modify all the shortcodes on your site.

Since you are already using a custom Markup Template for your site, the second way is probably better for you. You can change the “Item:” markup section, replacing the [+link+] portion with something like the following:

<a itemprop="contentURL" class="img-hyperlink" href="[+link_url+]"><img itemprop="thumbnailUrl" width="[+thumbnail_width+]" height="[+thumbnail_height+]" class="attachment-thumbnail" alt="[+title+]" src="[+thumbnail_url+]"></a>

Putting that in context, your “Item:” section would look like:

<figure itemprop="image" itemscope itemtype="https://schema.org/ImageObject" class="gallery-item col-[+columns+]">
	<div class="gallery-icon"><a itemprop="contentURL" class="img-hyperlink" href="[+link_url+]"><img itemprop="thumbnailUrl" width="[+thumbnail_width+]" height="[+thumbnail_height+]" class="attachment-thumbnail" alt="[+title+]" src="[+thumbnail_url+]"></a></div>
	<figcaption itemprop="caption" class="gallery-caption">[+caption+]</figcaption>
</figure>

I think that will give you the template you need to add schema attributes to your [mla_gallery] shortcodes. I am marking this topic resolved, but let me know if you have any problems or further questions. Thanks for your interest and for the question.
