When creating a field via PHP I must provide 3 properties:
- key: ACF unique identifier
- name: actual property name as contained in post data
- label: string displayed on the UI
Firstly, the statement about key requiring to start with "field_" seems incorrect as none of my fields key start with "field_" yet they all seem to be working properly, which brings me to 1st question:
Q1: Is the leading "field_" for keys a convention or is it really a working requirement, and if so, what won't work if I don't stick to it?
Secondly, all my fields are setup with repeaters whereby each specific field (eg a name, a URL, an image gallery) is associated with several generic fields to facilitate content management (eg a
is_enabled field so I can quickly enable/disable fields without deleting/recreating data, a
note field whereby I can provide explanations as to why I disabled something), which brings me to this 2nd question:
Q2: Can I have the same generic fields (eg
is_enabled) with identical key/name definition within different field groups & repeaters or should I make their key and/or name unique for each occurrence?
