Ajax响应没有在视图文件(Yii）中显示任何内容

我的视图中有一个文件（_gen.php），它将所选数据发送到控制器文件进行验证：

   $('#validate').on('click',function(){
        var data = []; // data container
        // collect all the checked checkboxes and their associated attributes
        $("table#subsection_table input[type='checkbox']:checked").each(function(){
            data.push({
                section : $(this).data('sectionid'),
                subsection : $(this).val(),
                year : $(this).data('year')

           })
       });
        // JSON it so that it can be passed via Ajax call to a php page
        var data = JSON.stringify(data);

        $.ajax({
            url : "<?php echo Yii::app()->createAbsoluteUrl("scheduler/ScheduleValidation"); ?>",
            type: "POST",
            data : "myData=" + data,
            success : function(data)
            {
                $("#ajax-results").html(data);
                $("#ajax-results").dialog({ width: 500, height: 500})
            },
            error: function()
            {
                alert("there was an error")
            }
        })
        console.log(JSON.stringify(data));
        $('#dialog').html(data).dialog({ width: 500, heigh: 500});
    });

现在#ajax结果是我的按钮后面的一个div标记的id（页面上最后显示的内容）。

至于控制器函数，我知道它处理数据很好，sql调用也很正确（我确定了）。然而，当我调用renderPartial时，它会正确地调用我的_ajax.php文件，但它只会在一个警告框中显示它，而不会显示在#ajax结果标记中。控制器功能：

  public function actionScheduleValidation()
{
    print_r("in ajax");
    $post_data = $_POST['myData'];
    $decodedData = json_decode($post_data, true);
    //$course = [[[]]];
    $course=[];
    $counter = 0;
    //Save the years associated to sections chosen
    foreach ($decodedData as $key) {
        $tutOrLab = null;
        $lec = null;
        $currentYear = null;
        foreach ($key as $id => $number) {
            if ($id == 'year') {
                $currentYear = $number;
            } elseif ($id == 'subsection') {
                $tutOrLab = Yii::app()->db->createCommand()
                    ->select('courseID,kind,days,start_time,end_time,semester')
                    ->from($id)
                    ->where('id=' . $number)
                    ->queryRow();
            } else

        print_r(gettype($lecture->getStartTime()));
        // WILL ACTUALLY DISPLAY SOMETHING

关于如何将它附加到我的原始（_gen.php）html代码中，有什么想法吗？
