jQueryでタグから値を取得できません

私のフォームにタグの値を取得しようとしましたが、できません。これはjquery http://aehlke.github.io/tag-it/です。jQueryでタグから値を取得できません

のindex.php

<form> 
    <p> Normally this input field will be hidden &mdash; we leave it visible here so you can see how it is manipulated by the widget: 
     <input name="tags" id="mySingleField" value="Apple, Orange" disabled="true"> 
    </p> 
    <ul id="singleFieldTags"></ul> 
    <input type="submit" value="Submit"> 
</form> 
<?php echo $_POST["tags"]; ?>

は再びinputフォーム要素&チェックからそのdisabled="true"を削除します。

&チェックの代わりに以下のピースコードを使用してください。

<form action="" method="post"> 
    <p> Normally this input field will be hidden &mdash; we leave it visible here so you can see how it is manipulated by the widget: 
     <input name="tags" id="mySingleField" value="Apple, Orange"> 
    </p> 
    <ul id="singleFieldTags"></ul> 
    <input type="submit" value="Submit"> 
</form> 
<?php echo $_POST["tags"]; ?>

OK、ここに私の完全なコードです。これをチェックして。

<?php 
error_reporting(E_ALL); 
ini_set('display_errors', '1'); 
?>
