I create a type group in which I insert an image field with img slug that you can create multiple instances.
Now my problem is that I want to display for example only one field value of img slug field.
Using
types_render_field('img', array())
it show all flied i insert for img slug field.
I also tried with
types_render_field('img[0], array());
but it doesn’t work.
Same problem, finally find this solution if someone need :
Instad of using types_render_field I access to custom fields value using get_post_custom function.
