[英]can't get $_GET variable in php session_start() script
我有一個名為fbconfig.php的文件
如果我將變量附加到URL http://localhost/fbconfig.php?amount = 700 ,則無法在腳本中檢索該變量。
<?php
session_start();
$amount = $_GET['amount'];
echo $amount; // NOTHING HAPPENS
// added in v4.0.0
require_once 'autoload.php';
//require 'functions.php';
require 'dbconfig.php';
use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;
use Facebook\Entities\AccessToken;
use Facebook\HttpClients\FacebookCurlHttpClient;
use Facebook\HttpClients\FacebookHttpable;
// Other Variables
// init app with app id and secret
FacebookSession::setDefaultApplication( '123123123','12312312' );
// login helper with redirect_uri
$helper = new FacebookRedirectLoginHelper('http://localhost/fbconfig.php' );
try {
$session = $helper->getSessionFromRedirect();
} catch( FacebookRequestException $ex ) {
// When Facebook returns an error
} catch( Exception $ex ) {
// When validation fails or other local issues
}
// see if we have a session
if ( isset( $session ) ) {
// graph api request for user data
$request = new FacebookRequest( $session, 'GET', '/me' );
$response = $request->execute();
// get response
$graphObject = $response->getGraphObject();
$fbid = $graphObject->getProperty('id'); // To Get Facebook ID
$fbfullname = $graphObject->getProperty('name'); // To Get Facebook full name
$fbfirstname = $graphObject->getProperty('first_name'); // To Get Facebook full name
$fbsecondname = $graphObject->getProperty('last_name'); // To Get Facebook full name
$femail = $graphObject->getProperty('email'); // To Get Facebook email ID
/* ---- Session Variables -----*/
$_SESSION['FBID'] = $fbid;
$_SESSION['FULLNAME'] = $fbfullname;
$_SESSION['EMAIL'] = $femail;
$_SESSION['FBFIRSTNAME'] = $fbfirstname;
$_SESSION['FBSECONDNAME'] = $fbsecondname;
//checkuser($fbid,$fbfullname,$femail,$amount,$days);
/* ---- header location after session ----*/
//header("Location: apply.php?amount=".$a."&days=".$b."");
} else {
$loginUrl = $helper->getLoginUrl();
//header("Location: ".$loginUrl);
}
echo $amount; // NOTHING HAPPENS
?>
那么有什么主意為什么我不能得到這個變量? 我嘗試了很多不同的方法
謝謝
