I have searched everywhere for a way to fix this issue but had no luck...
I have this movie database project that I built using the Gridly template. I use the Custom Content Types plugin. I use the regular posts as "movie cards", to which I have added relations to other custom posts (actors, directors...). The movie "cards" can be edited using Custom fields (one for actors, one for directors...). I did all this using Ed Andrea's well know tutorial on the subject.
I have installed WP Custom Fields Search to edit several search forms. One is for movie titles, that targets the post title > it works fine.
I have done the same thing to search for actors : I have selected "custom field" as Data Field and set "actors" in the dropdown menu as the one custom field that needs to be browsed. However, the Custom Content Types plugin works with item ids (for instance Bruce Willis is ['10'], Matt Damon is ['13']...) and won't return any data if I search for an actor's name. This seems to be an old issue, but the latest fixes don't change anything for me : if I want to see the Bruce Willis movies, I have to search for... number 11. It is not very convenient to say the least.
If anyone has any ideas, to fix this in WP custom fields search, or for a custom search form...
