我正在制作一个库存管理系统，如果您登录，您将被重定向到客户信息。

这是我在登录页面中的代码:

<?php
if(isset($_SESSION['KEY']))
{
header("location:datagrid_customer_info.php");
}
else
{

if(isset($_POST['btnLogin'])){
    require_once("_config.php");

    $txtEmail = $_POST['txtEmail'];
    $txtPassword = $_POST['txtPassword'];


    $STH = $DBH->prepare("SELECT * FROM view_login_info WHERE cEmail    =:txtEmail AND cPassword =:txtPassword");
    $STH->bindparam(":txtEmail",$txtEmail);
    $STH->bindparam(":txtPassword",$txtPassword);
    $STH->execute();
    $ROW = $STH->fetch(PDO::FETCH_ASSOC);
    $CTR = $STH->rowCount();
        if($CTR==1){
            session_start();
            $_SESSION['idLogin'] = $ROW['idLogin'];
            $_SESSION['KEY'] = 1;

            $STH = $DBH->prepare("UPDATE adm_login_info SET cLock=0,  cLastLogin = DATE_FORMAT(NOW(),'%Y-%m-%d %H:%i:%s') WHERE idLogin=:idLogin");
            $STH->bindparam(":idLogin",$ROW['idLogin']);
            $STH->execute();

            echo "<script type='text/javascript'>";
            echo "alert('Welcome to Inventory Management System');";
            echo "window.location.href='datagrid_customer_info.php';";
            echo "</script>";
        }else{
            echo "<script type='text/javascript'>";
            echo "alert('Login Error!');";
            echo "window.location.href='login.php';";
            echo "</script>";
        }   
}
?>

我真的不知道这里出了什么问题。我已经检查了我的cookie。

最佳答案

该问题似乎是由无限重定向循环引起的。我建议它在这里:

for($i=0;$i<count($checkbox);$i++){
     $del_id = $checkbox[$i];
     $STH = $DBH->prepare("DELETE FROM inv_customer_info WHERE idCustomer=:del_id");
     $STH->bindparam(":del_id",$del_id);
     $STH->execute();
     echo "<script type='text/javascript'>";
     echo "alert('Successfully Deleted');";
     echo "window.location.href='datagrid_customer_info.php';";
     echo "</script>";
 }

您正在循环重定向。

此外，在 php 中使用 header 可能会很复杂，我建议您使用刷新元标记。您可以像这样在 PHP 中使用它:

<?php
$location = 'destination/file.php?variable=value';
echo '<META http-equiv="refresh" content="0;URL='.$location.'">';
?>
