WordPress 5.4 – How to prevent to enter only certain values in custom field
WordPress version – 5.4.2
I am creating one WordPress plugin and in this plugin, I need one metadata for the post. I added meta box
accesstype visibility successfully. It is a select box and it has only fixed 3 values. it is working fine in block editor as shown below.
However, when I enable custom fields by going in options. it is allowing me to add any value in the text box and it will save it as shown below.
How can I hide
accesstype visibility from it or add a select box instead of a text box?
