[Resolved] Can I use conditional output with a repeatable field group

Hey

Is it possible to use conditional output with repeatable fields.

Basically all I want to do is check if any of the repeatable fields for a specific post have any content in them. If they are I will display a heading. If all blank heading won't display.

The reason the heading needs to work like this is it checks another field for content also not just this repeatable field group.

Thanks.

One way to accomplish this in Toolset alone is with a View of the Repeatable Field Group. Add a post relationship query filter, so that the parent post is set by the current page ( or the current post in the loop if you're displaying the main post in a View ). Then add a Query Filter for the custom field (or fields), and check that the field value is not empty. Set the limit to 1 post, since all you need to know is whether or not one exists. In the wpv-items-found section of the loop, add the heading information you want to display. In the wpv-no-items-found section, delete the text message. This View is now effectively a conditional that tests if any related RFG have content in the custom field(s) in your query filter.

If you need something more flexible, a custom shortcode approach is probably more practical. You can use the toolset_get_related_posts API to get all the RFGs for a specific post, then loop over them and inspect their post meta values. I can help with toolset_get_related_posts if you need more information. Basically an RFG is treated as a child of the main post. The slug of the relationship is identical to the RFG slug.

Hey Christian

Thanks for the detailed reply.

Your first point makes complete sense and is definitely an option albeit a little messy.

Your second point, I will be honest completely lost me. I understand what a custom shortcode is and have used some examples off the Toolset forums in the past but I just have no idea where to start with this.

As a third option I could have a tick box that a user ticks above the repeatable field group to enable the heading basically telling it look I have filled in the below fields so I have ticked this box, then I check if that has been fixed.

From a site speed perspective which do you think is the best option for me to go with?

The third option is definitely the most performant and requires the fewest queries, though it requires manual management on the backend.

For a few examples of the second option, you can check these other forum posts about looping over RFG:

Hi Christian

Hmm OK I might just go with option 3.

Ran into another issue though, can I use an AND and an OR statement in a conditional together?

so if (X) AND (X) OR (X) the show content.

Is this possible?

[Christian Cox]

Yes, simple combinations are possible. You must use parenthesis and order of operations, like in algebra.

[wpv-conditional if="( ( '1' eq '1' AND '2' eq '3' ) OR '3' eq '3' )"]
something here

My issue is resolved now. Thank you!
