Не работает валидация формы на jquery

$(document).ready(function() { 
  $function() { 
    var field = new Array('name', 'phone'); 
 
    $('form').submit(function() { 
      var error = 0; 
      $('form').find('input').each(function() { 
        for (var i = 0; i < field.length; i++) { 
          if ($(this).attr('name') == field[i]) { 
            if (!$(this).val()) { 
              $(this).css('border', 'red 1px solid'); 
              error = 1; 
            } else { 
              $(this).css('border', 'none'); 
            } 
          } 
        } 
      }) 
      if (error = 0) { 
        return true; 
      } else { 
        if (error = 1) var err_text = 'Not all fields are filled!'; 
        $('.messenger').html(err_text); 
        $('.messenger').fadeIn('slow'); 
        return false; 
      } 
    }) 
  } 
});
