hi cbvmercado,
I figured out as to how to add extra field as follows, hope this helps:
function my_fields($fields) {
$fields['new'] = '<p class="comment-form-antispam"</p>' .
'<label for="new">' . __( custom field ) . '</label>' .
'<span style="color:red; font-weight:bold"> *</span> ' .
'<br /><input id="new" name="new" type="text" maxlength="2" value="' .
esc_attr( $commenter['comment_new'] ) . '" size="10"' . $aria_req . ' />' .
'</p><!-- #form-section-new .form-section -->';
return $fields;
}
add_filter('comment_form_default_fields','my_fields');
I don’t know this: I want to make this custom field REQUIRED and use it for anti-spam simple math question like “what is 2+2?”, and be able to check the correct answer.
If you or someone else can help that be really great.
