我發現在你的代碼的一些錯誤停靠jQuery來驗證你的代碼

<script type="text/javascript"> 
    $(document).ready(function() { 
    $("#validation-form").validate({ 

     errorPlacement: function(error, element) { 
      $("p.field_validation_error").removeClass("hidden"); 
      error.appendTo('.field_validation_error'); // You forget . here 
     }, 
     rules: { 
     // this is how you need to define rules 
      "old_password": 
      { 
       required: true, 
       minlength: 2 
      } 
     }, 
     messages: { 
      // and message 
      old_password: 
      { 
       required: "Please enter your firstname", 
       minlength: "Your username must consist of at least 2 characters" 
      } 
     } 

    }); 
    }); 
</script>
