Php 命名参数PDO更新

我有JS代码，它由以下表单调用：

//////////////// About Tab
$(document).ready(function(){
    $("form#FanDetail").submit(function() {
    // store the values from the form input box, then send via ajax below
    var bio = $('#bio').val();
    var dob = $('#dob').val();
    var zip = $('#actualZip').val();
    var occup = $('#actualOccup').val();
    var fbkurl = $('#fbkurl').val();
    var twiturl = $('#twiturl').val();
    var phoNum = $('#phoNum').val();
    $.post(
            "../src/php/registration/about/submitvalues_about_tab.php",
            $("form#FanDetail").serialize(),
            function(){
                $('form#FanDetail').hide(function(){
                    $('div.success').fadeIn();
            });
          });
       return false;
    });
});

被js调用的Php代码：

**原始HTML代码**

<form method="post" id="FanDetail">
<textarea id="bio" name="fan_bio" cols="27" rows="3"></textarea><br />
<input id="dob" name="fan_dob" value="(e.g. 01/05/1965)" onFocus="clearText(this)" /><br />
<div class="ui-widget">
    <input id="zip" name="term" value="What is your Zipcode?" onFocus="clearText(this)" /><br />
    <input id="actualZip" type="hidden" name="actualzipval" value="" />
</div><!--ui-widget :: zip -->
    <div class="ui-widget">
    <input id="occup" type="text"  name="term2" value="e.g. Computer Programmer, etc" onFocus="clearText(this)" /><br />
    <input id="actualOccup" type="hidden" name="actualOccupval" value="" />
</div><!--ui-widget :: occup -->
<input id="fbkurl" type="text"  name="fan_fbk" value="e.g. SportsFan12" onFocus="clearText(this)" /><br />
<input id="twiturl" type="text"  name="fan_twit" value="e.g. AboutSports2012" onFocus="clearText(this)" /><br />
<input id="phoNum" type="text"  name="fan_pho" value="cell or home phone" onFocus="clearText(this)" /><br />
<input style="background-image:url('img/save.png');" type="submit" name="saveAbout" value="" id="submit" />
</form>
<div class="success" style="display:none;">Got it!</div>

*问题是，它仍然没有更新行，但它通过调用$sth->debugDumpParams；*它给了我上面的输出^^。这个回答有问题吗？请记住，try{}中的文件为空，没有写入错误。

简化此问题可能会帮助您获得更高质量的答案。添加了pastebin。如果你能帮忙，我会非常感激。你确定没有抛出异常吗？尝试错误日志$e->getMessage。如何输入硬编码的值？获取查询，在mysql中使用值运行它，如果需要的话。Catch block:catchPDOException$e中没有任何内容。
