如何存储从 isset($_GET['Something']) 获得的值以在 .php 页面中重复使用
[英]How can I store the value I get from the isset($_GET['Something']) for repeated use within the .php page
问题描述
<?php
include_once("Globals.php");
global $model;
I want to capture the $order_id value from the $_GET['claim_order'] for future re-use.
我想从 $_GET['claim_order'] 中捕获 $order_id 值以供将来重用。
if(isset($_GET['claim_order'])){
$order_id = $_GET['claim_order'];
}
for example the value saved in the $order_id variable is not available for repeat use on the current page.例如，$order_id 变量中保存的值不能在当前页面上重复使用。

<?php
if(isset($_GET["button_claim"])){
for example in the next 3 lines I try to use it but it returns the wrong value of 0 instead the correct value corresponding to the "button_claim".例如，在接下来的 3 行中，我尝试使用它，但它返回错误的值 0，而不是对应于“button_claim”的正确值。
I want to be able to refer to the value even if I refresh the.php page.即使我刷新 .php 页面，我也希望能够引用该值。
All I want to do is use that $order_id value in a SQL query.我要做的就是在 SQL 查询中使用该 $order_id 值。 It basically indicates the ID# of the order in question.它基本上表示相关订单的 ID#。
$care_giver_id = $model->getCurrentUserId();
global $order_id;
$sql = "UPDATE `order` SET `care_giver_id` = '$care_giver_id' WHERE `order_id` = '$order_id'";
if(!mysqli_query($conn, $sql)){
header("Location: fail.php");

If you want to store some short-term data, PHP sessions would be a sufficient solution.如果您想存储一些短期数据，PHP 会话将是一个足够的解决方案。 Keep in mind that this data will only last as long as your session lasts.请记住，这些数据只会持续到您的 session 持续的时间。
session_start();
$_SESSION['order_id'] = $_GET['claim_order'];
For a longer-term storage solution, consider storing the data in a database like MySQL or in a file (make sure to keep this file out of the web directory if it's holding private information).对于长期存储解决方案，请考虑将数据存储在 MySQL 等数据库或文件中（如果该文件包含私人信息，请确保将此文件保存在 web 目录之外）。

You can use the setcookie('name_of_cookie', $value);您可以使用setcookie('name_of_cookie', $value); and get this data using $_COOKIE('name_of_cookie');并使用$_COOKIE('name_of_cookie');获取此数据. . after this you can use the unset($_COOKIE('name_of_cookie'));在此之后，您可以使用unset($_COOKIE('name_of_cookie'));
