This filter can be used to change the type of link returned by Dropbox.


The following would apply to all forms:

add_filter( 'gform_dropbox_link_type', 'your_function_name', 10, 3 );

To target a specific form append the form id to the hook name. (format: gform_dropbox_link_type_FORMID)

add_filter( 'gform_dropbox_link_type_10', 'your_function_name', 10, 3 );

To target a specific field append both the form id and the field id to the hook name. (format: gform_dropbox_link_type_FORMID_FIELDID)

add_filter( 'gform_dropbox_link_type_10_3', 'your_function_name', 10, 3 );
