I got the all node type list in a variable using get_node_type_info() and now am passing this variable to field_info_instances as:
array_keys(field_info_instances("node", $op_keys));
ps: $op_keys is the variable to get node types. But this is giving me list of node_type "keys" and I want field "keys".
Either tell:
(1)how to pass list of all node types as a $bundle_name in field_info_instances() ?
or
(2) when selecting any of the node_type (as an option of select list) from select list, it's corresponding field's name will get rendered. I mean to say for example: node_type = "Article" and its field names = "body", "title", "image". when "article" got clicked from select list, "body", "title", "image" should get rendered.
