The issue

The comment form, as i planned to design it, will use Bootstrap's input groups and probably input addons. Translating in bare coins, the needed markup for each input is like this:

<section class="form-group">
    <input type="text" class="form-control" id="name" placeholder="Your name" />

Wordpress function comment_form(), as far as i know, doesn't allow this kind of markup. I can give id or classes to the form, to the submit button, but i was not able to find anything that lets me add wrapping elements and classes to inputs.

The question

Since i don't want to write my own function, cause i'm concerned about plugins not being able to function properly, is there a way to do this using as much native functions as possible? Thank you.


To avoid any misunderstanding, if not clear, i'm not asking a question about Bootstrap itself, but just how should i generate a precise markup with Wordpress.

  • @WebElaine And that won't cause issues? After all it is writing a custom function instead of using wp's one May 26, 2017 at 14:53
  • Most sites are customized at least a little, whether it's custom functions or filters. Shouldn't cause issues unless you let the site sit there for 5 years without updating your code to later standards. :)

Yeah this should be possible using the comment_form_default_fields filter, like so:

apply_filters( 'comment_form_default_fields', $fields );

$fields = array( 'name' => '<section class="form-group">
    <input type="text" class="form-control" id="name" placeholder="Your name" />

Just remember to add any other fields that you want to add into that array too.
