请帮帮我。提前致谢。其实我试图从html表单插入到mysql数据库。我的表单包含用户组合框，其中包含数据库中的数据。当我从组合框中选择用户时，将显示分配有文本框和价格文本框以输入数据的相应课程，这是我使用ajax完成的。 现在的情况是我无法将表单中的数据插入到mysql数据库中。我会一步一步地解释一切。
Inside UsersController.php页面 从add_price.ctp视图页面单击用户组合框时，以下功能将显示课程文本框和价格文本框
<?php
public function showprice()
{
$this->loadModel('Exam');
$id = $_POST['userid'];
if($id!=0)
{
$allPrice = $this->Exam->query("select * from exams where username = $id");
foreach($allPrice as $allPrices)
{
$total_price = $allPrices['exams']['exam'];
$price = explode(',',$total_price);
echo "<table class='tblrow' width='350px'>";
for($i=0;$i<count($price);$i++)
{
echo "<tr>";
echo "<td><label for='Course'>Course</label><input type='text' id='course' name='data[Price][course][]' value='$price[$i]'></td>";
echo "<td><label for='Price'>Price</label><input type='text' id='price' name='data[Price][price][]' value=''></td>";
echo "</tr>";
echo "<tr><td> </td></tr>";
}
}
echo "</table>";
}
else
{
echo "No results found";
}
die();
}
The below function is for inserting into Mysql database from the form.
public function price_submit()
{
// print_r($_POST);
if(isset($_POST['data']))
{
$this->loadModel('Price');
$priceData = $_POST['data'];
//$this->set(array('priceData'=>$priceData,'_serialize'=>'priceData'));
$this->Price->create();
$this->Price->save($priceData);
/*
if($this->Price->save($priceData))
{
echo "Data added successfully";
}
*/
if($this->Price->save($priceData))
{
//$this->Session->setFlash('<p style="width:220px;background-color:#34A853;color:white;text-align:center;font-weight:bold">User is Created Successfully</p>');
$this->redirect('index');
}
}
$this->loadModel('User');
//$userData = $this->User->find('all');
$userData = $this->User->query("select * from users where id!= 15 and id!= 8");
$this->set('users',$userData);
}

This code is for when selecting users from the combobox it will call the UsersController showprice function for displaying the courses and price textboxes.
$(document).ready(function(){
$('#user').change(function(){
var nameIdVal = $(this).val();
$.ajax({
type: "POST",
url: '/invl_exams/showprice',
cache: "false",
data: {userid:nameIdVal},
success : function(result){
//alert(result);
$('#divprice').html(result);
}
});
});
});
This code will call price_submit from the UsersController.php to insert into database
$(document).ready(function(){
$('.btn').click(function(event){
event.preventDefault();
$.ajax({

method: "POST",
