I am trying to pass variables between pages using a session. The codes works when I deploy it to my server but during local development it does not. Some background information, the session broke when I moved my development over to a mac where I am using MAMP (although I was using MAMP on my windows computer as well). I've made sure my save_path is defined in the php.ini and the folder is writable. The session keeps the data for the first page, but then when I advance onto the second page the session loses all the data.

Here is my code: First page (this works):

session_start();

// retrieve Application Name and API Key
$_SESSION['appName'] = $_POST['appName'];
$_SESSION['apiKey'] = $_POST['apiKey'];
$appName = $_SESSION['appName'];
$apiKey = $_SESSION['apiKey'];

// create app and connection
$app = establishConnection($appName, $apiKey);

Second page (this is where the data is lost):

session_start();

// set default timezone
date_default_timezone_set('America/New_York');

// include openrate sdk
require_once('src/isdk.php');
include 'src/openratesdk.php';

ini_set ('display_errors', 1);
error_reporting (E_ALL & ~E_NOTICE | E_STRICT);

// retrieve Application Name and API Key
$appName = $_SESSION['appName'];
$apiKey = $_SESSION['apiKey'];

// create app and connection
$app = establishConnection($appName, $apiKey);

I know the code is right since it's always worked until I moved my code over to a Mac so I am sure it has something to do with the php.ini file but I cannot figure out what it is. Any help would be appreciated.

Also here is my phpinfo():

[Newest Edit]: When I look at my session I have noticed it creates a whole new session for the second page load instead of accessing the one already created.

  • `error_reporting(E_ALL);` and add it to the top. – AbraCadaver Aug 06 '14 at 15:26
  • Try these previous answers: http://stackoverflow.com/questions/155920/php-session-data-not-being-saved – audittxl Aug 06 '14 at 15:27
  • I specified the path to: ini_set('session.save_path','/Users/sven/Syrup/session_data'); I still continue to have the same problem. Just to show you that it is working on the first one if I print_r($_SESSION) on both pages I can see that the variables are set in the first one but not the second one so the path couldn't be the issue. – sven13 Aug 06 '14 at 16:51

Are you sure /Applications/MAMP/tmp/php exist in your system.

session.save_path   /Applications/MAMP/tmp/php  /Applications/MAMP/tmp/php

Change the path which exists in your system like for windows 

session.save_path   "c:/tmp"

c:/tmp is just and example like me having folder tmp named inside the C drive.

the same like windows you need to check in Mac a proper directory which exist.

  • the problem is definitely save path. Macs are a lot like linux and folder permission is important. if you set it to /tmp make sure it's got public read/write permissions – Zombiesplat Aug 07 '14 at 21:12
  • oh.. and make sure to restart apache after you make the change to your ini – Zombiesplat Aug 07 '14 at 21:12

Am sure Session is not enabled and MAMP is different from WAMP and XAMPP. check for the permissions again. Right not in the first page also session is not working.

I found a soluation. I had to specific the session id before calling session_start(). I do not fully understand why this was necessary to work because by default the session already started should just be continued so if someone could explain why this was necessary, that'd be great.

session_id('OPENRATE');
session_start();
