index.php 包含登录表单
<?php
include('conexion.php');

validation.php 验证用户并重定向到角色对应的页面。
<?php
include('conexion.php');
$user = addslashes($_POST['user']);
$passw = addslashes($_POST['passw']);
#
$query_user = mysqli_query($conexion,"SELECT * FROM login WHERE user = '".$user."'");
$query_role = mysqli_query($conexion,"SELECT role FROM login WHERE user = '".$user."' ");
if(mysqli_num_rows($query_user) < 1){
echo "<script> alert('Error en datos...');</script>";
echo "<script>document.location.href = 'index.php'; </script>";
}else{
$query_passw = mysqli_query($conexion,"SELECT * FROM login WHERE user = '".$user."' AND password = '".$passw."' ");
if (mysqli_num_rows($query_passw) < 1) {
echo "<script> alert('Date Error...');</script>";
echo "<script>document.location.href = 'index.php'; </script>";
}else{
echo "<script> alert('SucIngreso Exitoso...');</script>";
$role = mysqli_fetch_assoc($query_role);
if(strcmp($role,"admin") == 0){
header('Location: admin.php');
}
elseif(strcmp($role,"user") == 0){
header('Location: user.php');
}
}
}
?>
进行查询以了解与启动会话的用户对应的角色并验证角色以将其重定向到相应的页面，但两个用户都被重定向到管理员角色的页面。
【问题讨论】：
-
把
strcmp($role,"admin")改成strcmp($role["role"],"admin")，因为mysqli_fetch_assoc返回一个关联数组 -
你需要参考一些教程。这里使用了许多不好的做法。您的
fetch用法也意味着您还没有看到它是如何返回的。 php.net/manual/en/mysqli-result.fetch-assoc.php 也不需要相同的查询 3 次，$consultar_user似乎永远不会设置。
