how to fill the value of a custom meta-box meta-data

I don’t know what you mean by “meta-data in a meta-box” and how that is different from setting a custom post field.

I apologize for not being able to explain myself properly. when using form to post plugin, in my form i have created in one of my input fields i can use ‘meta_’ for the name of this input field,which will dictate the key name for a custom field in the post and allow the user filling out the form to control the ‘value’ of the custom field. The issue with this, is if an admin goes into the post he/she is able to edit and change the key and value of this custom field.

To prevent admin from changing/editing the key of my post_meta, I have created post_meta in a meta box of my own, where the key is not exposed or able to be accessed/edited by an admin.

I have tried calling it by it’s name in the input ‘name’ but that does not work, and if i use ‘meta_’ then it’s name it creates a custom field which still exposes the key of this post meta to be touched.

Have you created a solution or know of how to resolve this issue?

Thank you for your patience.

I had to look up what a meta box is.

Let’s say that instead of a “meta_XXX” field, you have a “metabox_XXX” field. When the plugin sees the metabox_XXX field, what is is supposed to do? What function should it call?
