comment_form( array $args = array(), int|WP_Post $post_id = null )
Outputs a complete commenting form for use within a template.
Description Description
Most strings and form fields may be controlled through the $args array passed into the function, while you may also choose to use the ‘comment_form_default_fields’ filter to modify the array of default fields if you’d just like to add a new one or remove a single field. All fields are also individually passed through a filter of the ‘comment_form_field_$name’ where $name is the key used in the array of fields.
