命名参数PDO UPDATE

I have JS code, which is called by the form:

//////////////// 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;
    });
});

Php code which is called by js:

    ///////////////////////////////////////////////
    ######## Get  Input to Submit ############## //
    ///////////////////////////////////////////////
    $fanBio=$_POST['bio'];
    $fanDob=$_POST['dob'];
    $zipval=$_POST['zip'];
    $occupval=$_POST['occup'];
    $facebookurl=$_POST['fbkurl'];
    $twitterurl=$_POST['twiturl'];
    $phoneNum=$_POST['phoNum'];
    $fanID=1;


try{
    //$sessionvar = session_id();
    ### DB Connection already established above.
    $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );  
    $sth = $dbh->prepare("
    UPDATE Fan 
    SET fanBio=:fanBio,fanDob=:fanDob,fanDetLocID=:zipval,occupID=:occupval,fanFbk=:facebookurl,fanTwit=:twitterurl,fanPho=:phoneNum
    WHERE fanID=:fanID
    ");
    $sth->bindParam(':fanBio', $fanBio);
    $sth->bindParam(':fanDob', $fanDob);
    $sth->bindParam(':zipval', $fanZip);
    $sth->bindParam(':occupval', $fanOccup);
    $sth->bindParam(':facebookurl', $fanFbk);
    $sth->bindParam(':twitterurl', $fanTwit);
    $sth->bindParam(':phoneNum', $fanPhone);
    $sth->bindParam(':fanID', $fanID);
    $sth->execute(array(':fanBio' => $fanBio,':fanDob' => $fanDob,':zipval' => $zipval,':occupval' => $occupval,':facebookurl' => $facebookurl,':twitterurl' => $twitterurl,':phoneNum' => $phoneNum,':fanID' => $fanID));

    $sth->debugDumpParams(); ## debugging query
} 

catch(PDOException $e){
echo "ERROR HAS HAPPENED CATCH{}";
file_put_contents('../../../../PDODBConnectionErrors.txt','ERROR: [submitvalues_about_tab.php] about '.$e->getMessage(), FILE_APPEND);  
}

** RAW HTML Code**

<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>

I originally tried using:

1. Positioned Placeholders: with no success (getting same error as stated below)
2. Checked to make sure the query worked by putting in values hardcoded like UPDATE Fan and it worked fine.
3. made sure nothing was in file that is located in the catch{} block (not shown)
4. Checked to make sure my localhost allowed PDO, which it does.

Output by SQL: [165] UPDATE Fan SET fanBio=:fanBio,fanDob=:fanDob,fanDetLocID=:zipval,occupID=:occupval,fanFbk=:facebookurl,fanTwit=:twitterurl,fanPho=:phoneNum WHERE fanID=:fanID

    Params:  8
    Key: Name: [7] :fanBio
    paramno=-1
    name=[7] ":fanBio"
    is_param=1
    param_type=2
    Key: Name: [7] :fanDob
    paramno=-1
    name=[7] ":fanDob"
    is_param=1
    param_type=2
    Key: Name: [7] :zipval
    paramno=-1
    name=[7] ":zipval"
    is_param=1
    param_type=2

*the problem is, it still doesnt update the row, but it gives me a response back by calling the $sth->debugDumpParams(); * it gives me the above output ^^ . Is something wrong with this response? Keep in mind the file in try{} is blank, with no errors written to it.
