Ajax JSON PHP Stringify 没有发布但返回成功

Ajax JSON PHP Stringify not posting but returning successfully

我有一个 ajax 脚本,它从输入中收集值,然后使用 MYSQLI.

插入到 mysql 数据库中

当我单击按钮时,唯一 ID 成功返回,但 post 值中的 none 被插入到数据库中。此外,当单独测试 post 值时,它们也不会显示为到达 posted php 脚本。

在 运行 之后,唯一的 ID 在数据库中,但没有存储其他信息。

Q. How come the variables not reaching the PHP, thus preventing me from a successful insertion to the database?

Ajax

$('#postData').click(function() {
        smallVan_getForm_values();

    $.ajax({
     type: "POST",
     dataType: "json",
     url: "//xxxxx",
     data: JSON.stringify({
            book_email:book_email,
            book_clientTitle : book_clientTitle,
            book_firstname : book_firstname,
            book_lastname :book_lastname,
            book_dateofbirth : book_dateofbirth,
            book_primarycontactnumber : book_primarycontactnumber,
            book_secondarycontactnumber : book_secondarycontactnumber,
            departing_first_lineaddress : departing_first_lineaddress,
            departing_second_lineaddress : departing_second_lineaddress,
            departing_postcode : departing_postcode,
            destination_first_lineaddress : destination_first_lineaddress,
            destination_second_lineaddress : destination_second_lineaddress,
            destination_postcode : destination_postcode,

    }),
     contentType: "application/json; charset=utf-8",

        success: function (result) {
        //  alert(result);

            if (result.status == "success"){
                    uniqueID = result.uniqueID;
                    alert(uniqueID);

            }

       }
    });

});

});
//AJAX END

PHP

if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && !empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest')
{ //if request made from localserver then proceed here
    insertData();
}


function insertData() {

$uniqueID = substr(str_shuffle(str_repeat("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWYXZ", 10)), 0, 10);


    $conn=mysqli_connect("xxxx","xxx","xxxxx^","xxxxx");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    // Perform queries
    mysqli_query($conn,"INSERT INTO bookings_table ( booking_uniqueID , book_email , book_clientTitle , book_firstname , book_lastname , book_dateofbirth , book_primarycontactnumber , book_secondarycontactnumber , departing_first_lineaddress , departing_second_lineaddress , departing_postcode , destination_first_lineaddress , destination_second_lineaddress , destination_postcode , amount , book_consignmentdate , book_timeofbooking , book_additionalnotes )
   VALUES ( '$uniqueID' , '$_POST[book_email]' , '$_POST[book_clientTitle]' , '$_POST[book_firstname]' , '$_POST[book_lastname]' , '$_POST[book_dateofbirth]' , '$_POST[book_primarycontactnumber]' , '$_POST[book_secondarycontactnumber]' , '$_POST[departing_first_lineaddress]' , '$_POST[departing_second_lineaddress]' , '$_POST[departing_postcode]' , '$_POST[destination_first_lineaddress]' , '$_POST[destination_second_lineaddress]' , '$_POST[destination_postcode]' , '$_POST[amount]' , '$_POST[book_consignmentdate]' , '$_POST[book_timeofbooking]' , '$_POST[book_additionalnotes]' )");

    mysqli_close($conn);
    echo json_encode(array('status' => 'success', 'uniqueID' => $uniqueID));

}

只需删除您的 JSON.stringify()。
