Thanks for the tip, useful. Interesting to know that ‘comment’ is not one of the options for “post_type” when calling “add_meta_box”, 4th argument.

Also, you forgot to mention that you need to hook the add_meta_boxes before you can call the “add_meta_box” function you created as in:

add_action( ‘add_meta_boxes’, ‘add_meta_boxes’ );

function add_meta_boxes()
{
// Add to the admin_init function
add_meta_box(‘shiba_comment_xtra_box’, __(‘Extra Arguments’), ‘my_metabox’, ‘comment’, ‘normal’);
}

Can you give me a hint how can I remove the ‘namediv’ metabox from this editcomment screen?

Thanks for this great tutorial. I want to give comment author to edit his own comment. So need to disable the name, email and url field from the Author metabox also disable to edit the comment date and time to edit. But not with css want to do it with filter or hook.

Comment author can just update the content.

I tried to remove the metabox with remove_meta_box( ‘namediv’ , ‘comment’ , ‘normal’ );

but did not work.

Can tell me how can I do it?

Hello Ren,

The arguments passed in depends on which WordPress hook we use. In the example above, I used the ‘comment_save_pre’ hook, which passes back the comment content argument. This is set in WP native code. Here is more on WordPress hooks.

Why does the ‘save_mycomment_data’ function takes in $comment_content as a parameter? Can it take $comment or $comment_id as a parameter?

For most tutorials on adding meta boxes on pages or posts, the save data function always takes in $post_id as a parameter. Why is it different on saving comment data? Thanks in advance for your answer!

Update – I checked it out and all you need to do is expand the screen check condition to include the post screen. For example-

if (in_array($screen->id, array('edit-comments','post')) ) {

I do my comment edits on the comment admin screens so this is not something I have looked at.

Thanks for posting on extend metabox in commend edit screen.

It really works. but how to extend it in comment metabox when you at post edit screen?

Thank you.
