如何在2个php文件之间传递变量
I have two php files to make authentication to active directory users, i want to get the attribute url
from it and pass this variable $data
from authenticate.php
to login.php
if the function returned true to be in the location of header("Location: *URL*");
,how can this be done?
authenticate.php:
<?php
// Initialize session
session_start();
function authenticate($user, $password) {
if(empty($user) || empty($password)) return false;
// Active Directory server
$ldap_host = "CRAMSDCR01V.cloud4rain.local";
// connect to active directory
$ldap = ldap_connect($ldap_host);
$ldap_dn="OU=by-style,DC=cloud4rain,DC=local";
// verify user and password
if($bind = @ldap_bind($ldap, $user, $password))
{
$result = ldap_search($ldap,$ldap_dn, "(cn=*)") or die ("Error in search query: ".ldap_error($ldap));
$data = ldap_get_entries($ldap, $result);
echo $data["url"];
return true;
}
else
{
// invalid name or password
return false;
}
}
?>
login.php:
<?php
include("authenticate.php");
// check to see if user is logging out
if(isset($_GET['out'])) {
// destroy session
session_unset();
$_SESSION = array();
unset($_SESSION['user'],$_SESSION['access']);
session_destroy();
}
// check to see if login form has been submitted
if(isset($_POST['btn-login'])){
// run information through authenticator
if(authenticate($_POST['userLogin'],$_POST['userPassword']))
{
// authentication passed
header("Location: authenticate.php?$data");
die();
} else {
// authentication failed
$error = "Login failed: Incorrect user name, password, or rights<br /-->";
}
}
// output logout success
if(isset($_GET['out'])) echo "Logout successful";
?>
我有两个php文件对活动目录用户进行身份验证,我想获取属性 authenticate.php: p>
login.php: p>
url 来自它并将此变量
$ data code>从
authenticate.php code>传递给
login.php code>,如果函数返回true则位于该位置
header(“Location:* URL *”); code>,如何做到这一点? p>
&lt;?php
//初始化会话
session_start();
函数验证($ user,$ password){
if(empty($ user)|| empty($ password) ))返回false;
// Active Directory服务器
$ ldap_host =“CRAMSDCR01V.cloud4rain.local”;
//连接到活动目录
$ ldap = ldap_connect($ ldap_host);
$ ldap_dn =“OU = by-style,DC = cloud4rain,DC = local”;
//验证用户和密码
if($ bind = @ldap_bind($ ldap,$ user,$ password) )
{
$ result = ldap_search($ ldap,$ ldap_dn,“(cn = *)”)或die(“搜索查询中的错误:”。oldap_error($ ldap));
$ data = ldap_get_entries($ ldap,$ result);
echo $ data [“url”];
返回true;
}
其他
{
//名称或密码无效
返回false;
}
}
?&gt;
code> pre>
&lt;?php
include(“authenticate.php”);
//检查用户是否正在退出
if(isset) ($ _GET ['out'])){
// destroy session
session_unset();
$ _SESSION = array();
unset($ _ SESSION ['user'],$ _ SESSION ['access']) ;
session_destroy();
}
//检查登录表单是否已提交
if(isset($ _ POST ['btn-login'])){
//通过身份验证器运行信息\ nif(authenticate($ _ POST ['userLogin'],$ _ POST ['userPassword']))
{
//身份验证传递
标题(“位置:authenticate.php?$ data”);
die( );
} else {
//身份验证失败
$ error =“登录失败:用户名,密码或权限不正确&lt; br / - &gt;”;
}
}
/ n / output logout success
if(isset($ _ GET ['out']))echo“Logout successful”;
?&gt;
code> pre>
div>
login.php
<?php
include("authenticate.php");
That essentially acts like pasting the contents of authenticate.php inside login.php so although it's technically 2 files, it acts as if it's just the one - however $data
is defined within the authenticate()
function and so is only scoped within that function.
In authenticate.php - return the data from the function
// verify user and password
if($bind = @ldap_bind($ldap, $user, $password))
{
$result = ldap_search($ldap,$ldap_dn, "(cn=*)") or die ("Error in search query: ".ldap_error($ldap));
$data = ldap_get_entries($ldap, $result);
// echo $data["url"]; // I assume this is just for debugging...
// return $data from the function which should be "truthy"
return $data;
}
else
{
// invalid name or password
return false;
}
In login.php - evaluate the return from the authenticate()
function - since PHP is loosely typed any (non-empty) string returned by the function can be evaluated as being "truthy" - the only other returns you have from the function are false
so...
// run information through authenticator
if($authData = authenticate($_POST['userLogin'],$_POST['userPassword']))
{
// authentication passed
// renamed the variable $authData just for clarity
header("Location: authenticate.php?$authData");
die();
}
else {
// authentication failed
$error = "Login failed: Incorrect user name, password, or rights<br />";
}
Not sure why you have $_SESSION = array();
in login.php but if you want to pass $data from one php to another then just set it in session as
$_SESSION['data'] = $data;
ang to get it in the other file use
$data = $_SESSION['data'];
