frm_field_type

Use this code to hide fields from all user types except editors. The field will still be visible in the admin area.

add_filter('frm_field_type', 'change_my_field_type', 10, 2);
function change_my_field_type($type, $field){
  if(in_array($field->id, array(125,126,127))){ //change 125, 126, and 127 to the ids of fields to hide
   if(!is_admin() and !current_user_can('editor'))//if current user is not an editor
$type = 'hidden'; //hide the fields
  }
  return $type;
}

Use this code to hide certain fields when users are editing forms. The fields will still be visible in the admin area when editing entries.

add_filter('frm_field_type', 'change_my_field_type', 10, 2);
function change_my_field_type($type, $field){
 if(in_array($field->id, array(125, 126))){ //change 125 and 126 to the ids of the fields to hide
      global $frm_vars;
      if((!is_admin() || defined('DOING_AJAX')) && isset($frm_vars['editing_entry']) && $frm_vars['editing_entry']) { 
        //if not in admin area and editing an entry
        $type = 'hidden'; //hide this field
      }
  }
  return $type;
}

Use this code to hide certain fields when users are creating an entry (show field(s) only when editing). The fields will still be visible in the admin area when creating entries.

add_filter('frm_field_type', 'change_my_field_type', 10, 2);
function change_my_field_type($type, $field){
 if(in_array($field->id, array(125, 126))){ //change 125 and 126 to the ids of the fields to hide
      global $frm_vars;
      if((!is_admin() || defined('DOING_AJAX')) && (!isset($frm_vars['editing_entry']) || !$frm_vars['editing_entry'])) {
        //if not in admin area and not editing an entry
        $type = 'hidden'; //hide this field
      }
  }
  return $type;
}

add_filter('frm_field_type', 'change_my_field_type', 10, 3);
function change_my_field_type($type, $field, $value){
  if($field->id == 25){ //change 25 to the id of the field to conditionally hide
    global $my_required_id, $user_ID; 
    if($my_required_id == $user_ID) //if current user is not an editor
      $type = 'hidden'; //hide this field
  }else if($field->id == 21){ //change 21 to the id of the field to depend on
     global $my_required_id; 
     $my_required_id = $value; //save the required value to reference when we hit the other field
  }
  return $type;
