javascript - SQL 查询 - 替换字段名称中的句点

因此，我有一个使用 Ajax/Jquery 将数组 POST 到此 PHP 文件的表单，该文件应该将数组写入 MySQL 数据库。在过去的两周里，我查看了几个示例并改进了代码结构，但我觉得我可能遗漏了一些明显的东西。要么是这样，要么是做一些效率很低的事情。作为其他文件的背景，表单本身有一些带有句点的输入名称，这就是其中有 preg_replace 的原因。 Variables.php 文件包含所有正确的 SQL 登录数据，因为数据的后端查看正在运行。所有不起作用的是数据的实际写入。

但是，如果此代码段看起来应该可以工作，那么我需要再次检查我的 Javascript 文件。

这是 PHP 代码:

include 'variables.php';

if (isset($_POST)){
    mysqli_connect($mysql_hostname,$mysql_username,$mysql_password);
    mysqli_select_db($con,$mysql_table);
    $sql = sprintf('INSERT INTO '.$mysql_table.' (%s) VALUES ("%s")',
    implode(',',array_keys(preg_replace("/[^,.]/",$_fields))),
    implode('","',array_values(preg_replace("/[^,.]/",$_fields)))
    );
    mysqli_query($con,$sql);
    mysqli_close($con);
};

以下是捕获表单数据的 Javascript 代码:

var orderSubTotal ='46.15';
var orderTotal  ='46.15';
var numOfItems ='2';
var items =new Array('item1','item2');
var ids =new Array('id1','id2');
var codes =new Array('code1','code2');
var qtys =new Array('1','1');
var price =new Array('44.95','1.2');
var orderTax ='0';
var orderShipping ='0';
var appliedPromoIdList ='';
var coupon ='';
var storeId ='storeid';
var activeShipPromotionCount ='';
var itemImages  =new Array('image1','image2');

$(document).ready(function() {

$("#driver").click(function(event) {
    event.PreventDefault();

    var date=new Date();
    var formData = $("#testform :input[id!='card-type'][id!='paymentSelection_0']"+
    "[id!='ccSelectedRadio'][id!='card-number'][id!='card-exp-month'][id!='card-exp-year'][id!='card-cvv'][id!='billing-first-name']"+
    "[id!='billing-last-name'][id!='billing-company'][id!='billing-address1'][id!='billing-address2'][id!='billing-city']"+
    "[id!='billing-state'][id!='billing-zip'][id!='billing-phone'][id!='billing-country'][id!='useShippingRadio'][id!='useBillingRadio']"+
    "[id!='ppSelectedRadio'][name!='miscDS.shopperEmailAddress_ymixval'][name!='miscDS.shopperEmailAddress_ymixlabel']"+
    "[name!='miscDS.shopperEmailAddress_secname'][name!='paymentSelectionDS.paymentSelection_ROW0_paymentPPSelected']").serializeArray();

    formData.push({name: 'Subtotal', value: orderSubTotal});
    formData.push({name: 'Total', value: orderTotal});
    formData.push({name: 'Cart Size', value: numOfItems});
    formData.push({name: 'Cart Contains', value: items});
    formData.push({name: 'Item ID\'s', value: ids});
    formData.push({name: 'Codes', value: codes});
    formData.push({name: 'Quantities', value: qtys});
    formData.push({name: 'Prices', value: price});
    formData.push({name: 'Taxable', value: orderTax});
    formData.push({name: 'Shipping', value: orderShipping});
    formData.push({name: 'Applied Promotion ID\'s', value: appliedPromoIdList});
    formData.push({name: 'Coupons', value: coupon});
    formData.push({name: 'Store ID', value: storeId});
    formData.push({name: 'Shipping Promotion\'s', value: activeShipPromotionCount});
    formData.push({name: 'Item Images', value: itemImages});
    formData.push({name: 'Date and Time', value: date});

    $.post("jquery/process.php", formData);
});
});

最后，这是表单本身(我已经删除了表单中被 ajax 帖子排除或根本没有被拉出的部分):

最佳答案

看着上面的代码，我不得不承认我在 PHP 文件之后停了下来。简单的回答是 preg_replace 需要 3 个参数而不是 2 个才能工作。第一个参数是您要查找的模式，第二个参数是替换，最后一个参数是文本。

如果您希望改进整体代码，这里有一些建议:

首先，检查 $_POST 不是最好的选择，您应该检查

$_SERVER["REQUEST_METHOD"]=="POST"

然后请验证您的输入，我必须承认我从未使用过 $_fields 变量，但如果它预先填充了 $_POST 数组内的元素，您应该考虑到其中可以包含任何内容，而不仅仅是您期望的内容你的表单(其他人可以使用curl来破解该代码并在数据库中添加任何内容)。

您还应该在输入中结合使用 stripslashes 和 addslashes 来提供最低级别的安全性。冒号不是你唯一的问题，那里还可能有其他东西，一些你不想要的东西。

最后你可以使用 str_replace("要替换的字符串","替换","需要替换字符串的某些文本")

希望这有帮助
