Question

我有一个ajax脚本，它从输入中获取值，然后使用MYSQLI插入到mysql数据库。

当我单击按钮时，将成功返回唯一ID，但没有任何post值插入到数据库中。此外，当单独测试post值时，它们也不会显示为已发布的php脚本。

运行此命令后，唯一ID位于数据库中，但不存储其他信息。

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,

只需删除您的JSON.stringify（）。

data: {
            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,
            amount : amount,
            book_consignmentdate : book_consignmentdate,
            book_timeofbooking : book_timeofbooking,
            book_additionalnotes : book_additionalnotes
    },
