Hi Luoy,
I corrected my error. I just placed my shortcode outside of the parent view and so it didn't work. Now it is okay. Now I just have another issue: I am building this form (with CRED) to insert guided tours on a website. Each guided tour is a CPT and is a child of 'Attractions' CPT and 'Guides' CPT. Thanks to your help now I can filter the attractions by a guide geographic region and populate the select field for "_wpcf_belongs_parchi_id" which will set the proper relationship between the guided tour and the attraction. I have another field "_wpcf_belongs_guide_id" which is used to set the relationship between the guided tour and the registered guide: it is rendered as a very long select listing all the registered guides on the website. I can also set the default value of the select to the currently logged guide, which is already something, but I would rather use an hidden field with just the currently logged guide or maybe a single line text field (non editable) with the logged guide. Any idea on how I can achieve this?
Thanks a lot….
