将PHP页面重定向到另一个PHP页面

Question

我有一个register.php，login.php和main.php。如何在注册后提交登录页面然后登录页面提交至主页面后重定向用户。

Answer 1

header("Location: /login.php");

Answer 2

header("Location: /login.php"); 
exit; 

见exit。不要有史以来忘记这样做。如果您之后有敏感数据，任何不遵守位置标题的人都可以看到（such as some bots）。

要忘记阻止你，你可以建立一个包装类型的函数

function redirect($url) { 
    header('Location: ' . $url); 
    exit; 
} 

Answer 3

`Header("Location:login.php");` 

或： echo "<meta http-equiv=refresh content='0; url=login.php'>";

或：

echo "<script language='javascript'>"; 
echo "location='login.php';"; 
echo "</script>"; 

Answer 4

你可以这样做：

func.php

<?php 
function EmptyStr($value){ 
    $str = strval($value); 
    $str = str_replace("&nbsp;", "", $str); 
    return (trim($str) == ""); 
} 

function redirect($url) { 
header('Location: ' . $url); 
exit; 
} 
?> 

register.php

<?php 
include("func.php"); 
$username = $_POST["username]; 
$password = $_POST["password"]; 
$email = $_POST["email"]; 
if(!EmptyStr($username) && !EmptyStr($password) && !EmptyStr($email)){ 
    sql = WRITE YOUR SQL SYNTAX HERE TO INSERT THE INPUT TO DB 
    redirect("/login.php"); 
}else{ 
    $_SESSION["ErrMsg"] = "Error! All fields are required."; 
} 

echo $_SESSION["ErrMsg"]; 
$_SESSION["ErrMsg"] = ""; 
?> 
Put your html regsitration form here 

的login.php

<?php 
include("func.php"); 
$username = $_POST["username]; 
$password = $_POST["password"]; 

if(!EmptyStr($username) && !EmptyStr($password)){ 
    sql = WRITE YOUR SQL SYNTAX HERE TO QUERY THE USERNAME AND PASSWORD TO DB 
    if ($rs && !$rs->EOF) { //user found and pass match 
     $_SESSION["username"] = $username; 
     redirect("/main.php"); 
    }else{ 
     $_SESSION["ErrMsg"] = "Invalid username or passsword!"; 
    } 
}else{ 
    $_SESSION["ErrMsg"] = "Error! All fields are required."; 
} 

echo $_SESSION["ErrMsg"]; 
$_SESSION["ErrMsg"] = ""; 
?> 

Put your html login form here 

main.php

<?php 
include("func.php"); 
if(EmptyStr($_SESSION["username"])){ //check if user has session (logged in) 
    $_SESSION["ErrMsg"] = "You need to logged in first to view this page!"; 
    redirect("/login.php"); 
} 
?>
