 * The themes used would need to use the `comment_form()` function for the related
   filters to work, have you verified this is the case?
 * The filters are setup for adding fields above the comment textarea only, but 
   you can actually use the ‘comment_form_field_comment’ filter to add a separate
   field after the textarea, just do something like this:
 *     ```
       function add_example_field($textarea){
          return $textarea.'Label: <input id="example" name="example" type="text">';
       }
       add_filter( 'comment_form_field_comment', 'add_example_field' );
       ```
   
 * Then hook the ‘pre_comment_on_post’ action to capture the field value and do 
   something with it.

 * I have used that function as plugin for standalone wp and it wont worked. there
   were no any changes on comment fields.
    I have tried function below:
 *     ```
       function add_field () {
       echo '<input name="extra_field" title="somthing_extra />"';
       }
       add_action("comment_form","add_field");
       ```
   
 * By use of function above (add_field) I am able to show extra field after submit
   button, but actually I need extra field to be displayed before the submit button.

 * My theme`s comments.php rewrites what is generate by plugin. I am not sure how
   to overwrite it :S What I need is plugin which will overwrite comment fields 
   for all themes in my wp network.

 * The code I suggested works for any theme using the `comment_form()` function,
   I did test it before posting. If it does not work, you either have an error in
   how you implemented the code snippet or your theme does not use the comment form
   function.
 * In the latter case, how you add the field would depend on the code the theme 
   is using. There may not be any hook you can use for a plugin solution, you may
   need to alter the theme template directly so that it does call `comment_form()`,
   or directly hack the theme’s form generation code.
 * To avoid losing such changes to themes, you need to create a child theme for 
   each theme that was so customized.
