I’ve seen in various tutorials where people white the custom field Name in this fashion: intro-image. I thought I would make more sense to use (user friendly names instead of something that looks like a variable).
Is using hyphen (or underscore) a good practice?
You can use spaces and uppercase chars(periods, commas, and more) without worry. Only time you’ll see any problems is with
register_globalson(strict array key names when enabled), but who has it enabled these days?Any of these should be fine as custom field names.
Use whichever you prefer.. 🙂
I have always use “custom_field_name” and never had any problems with that but i guess that with a more user friendly approach “Custom Field Name” you could run into wired problems.
