how to change value of submit button of comment form?

Question

I wanted to change the default value of submit button in comment form from "Save" to "Post". I wanted to do that using a module , not javascript. So I wrote the following code in my module.

 function mymodule_form_comment_form_alter(&$form, &$form_state, $form_id){

     $form['actions']['submit'] = array(

      '#value' => t('Post Comments'),   
     );
     }

But instead of changing the value of submit button, this module is making the submit button hidden. If I add return $form , then the submit button displays but with the same default text "Save". Any suggestions please. Thank you.

You're replacing the entire element at the moment (which is why it doesn't show). You can change a specific property in the array like so:

$form['actions']['submit']['#value'] = t('Post Comments');

That way you're just setting the #value property, and not removing the other properties that already exist for the element.
