Hi there

I need to check if a specific custom field exists in general for the actual installation.
So if this field exists, I need to get TRUE even if the value is empty.

Thanks for a hint, couldn't find anything online for meta box.

Best regards
François

Hello,

You can try to use the function get_post_meta() to get a custom field of a post if it exists. Following the documentation
