Forms: 3rd-Party File Attachments

ہرہک دے سوال

How do I perform the appropriate transforms in custom hooks

Using F3i_Files_Base::Transform($value, $how) where $how is:
* path
* url
* base64
* raw

Gravity Forms input ids cause conflicts

Use the ‘label’ option to instead reference file uploads via the field label. You can also set the Advanced > Admin Field Label to use a shorter/non-display label than what users see on the form.

ex) If your upload field input_5 has a very long label “Choose one or more files blah blah blah” you would reference details like Choose one or more files blah blah blah_attach unless you set an admin label like “FileUpload”, in which case you’d map to FileUpload_attach. You can also use this to attach to different upload fields across forms — normally they might not be able to share the input_id, but if you give them the same admin field label then you only need to map the service once to that admin label.

This only works for GF or CF7, what about Ninja Forms or some other form plugin?

Message the author about adding it, or:
1. extend F3i_Files_Base and declare a method get_files that returns an array of (input_field => filepath)
2. hook to F3i_Files_Base_register and declare a new instance of your class

(A note about Ninja Forms — file uploads are a paid addon, and the author doesn’t have a copy, so adding it wasn’t on the roadmap)

It doesn’t work right…
