Problem:
The issue here is that the user wanted to know if Toolset is able to setup the schema.org

Solution:

Unfortunately this is not something that can be done with our Toolset plugins.

However it can be achieved with the Yoast plugin and I would recommend taking a look at the link below.

Problem:

The issue here is that the user wanted to check if a repeating field has any empty values.

Solution:

This can be done by using the code below.

[wpv-for-each field="wpcf-my-field"]
 
[wpv-conditional if="'[types field='my-field'][/types]' ne '' "]
 
Content goes here if field is NOT empty
 
[/wpv-conditional]
 
[/wpv-for-each]

What the above code will do is to loop through each index of the field then with the conditional checking if that index is empty. Finally replace "wpcf-my-field" with the slug of your image field keeping the wpcf- prefix EXCEPT when it is being called in the types shortcode.
