Only allow Admins to post comments

If your theme is calling the comment form like this in comments.php:

<?php comment_form(); ?>

You can change it to this so only admins can comment:

<?php
if(is_user_logged_in() && current_user_can('administrator')) {
  comment_form();
}
?>

or for all roles but subscribers:

<?php
if(is_user_logged_in() && !current_user_can('subscriber')) {
  comment_form();
}
?>

That is amazing. Thank you. That worked beautifully. You are my hero of the week.

You’re welcome. Glad you got it resolved.

Is there a way to only allow original poster and admin to comment back and forth?

By “original poster” you mean the author of the post?

yes

To give you more information – I am starting a Question/Answer site where I charge for answers – its a consultation site. I dont want others to be able to answer the questions. Only me.

That certainly can be done. I don’t have time right now but I will look into it tomorrow. Or maybe someone else might want to chime in.

great – I would appreciate any help – thank you very much!

Try it with this:

<?php
$current_user_id =  get_current_user_id();
$author_id = get_the_author_meta( 'ID' );
if(is_user_logged_in()) {
  if(current_user_can('administrator') || ($current_user_id == $author_id)) {
    comment_form();
  }
}
?>

Im sorry – Im so new to this – does that code go in the comment.php file? and do I have to erase anything and replace with this?

in your comments.php file replace this:

comment_form();

with this:

$current_user_id =  get_current_user_id();
$author_id = get_the_author_meta( 'ID' );
if(is_user_logged_in()) {
  if(current_user_can('administrator') || ($current_user_id == $author_id)) {
    comment_form();
  }
}

Can you look at my code above and tell me where to replace? I dont see the exact place you have instructed me to do that.

Thank you- Im sorry for the beginner questions.

And could you also tell me how to remove the “this is the best answer” box ?
