会话变量未保存在iPhone上

Question

UPDATE:

I was using .htaccess to redirect users to a specific folder (/var/www/html/test) that had all these files when they accessed my website. The .htaccess looked like this

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule (?!^test(/.*|)$)^(.*)$ /test/$1 [NC,L]
</IfModule>

When I moved all the files to /var/www/html and commented the .htaccess lines.. The sessions on iphone started working... I have no idea why.. Is there a way to fix that with .htaccess?

---- End Of Update -----

I have an ajax function that calls a user login function and if the user/password are correct, it logs in the user. It works on the desktop, laptop, samsung s3 phones but NOT on the IPHONE! The $this->session->set_userdata('current_email', $email); seem not to set the session on the IPHONE therefore redirecting user back to login page. I am guessing maybe that's because iphone safari cookies are disabled automatically or something like that. What's the best way to go around this so it works on the phone?

ajax:

$.ajax({
                url: site_url+"/user/login/"+email,
                type: "post",
                data: 'password='+password+'&email='+email,
                success: function(response){    
                    if(response == "success"){
                      window.location.href = site_url+"/user/invites";
                    }else{
                      alert("Password is not valid");
                    }   
                },  
                error: function(){
                }   
            }); 

/user/login php codeigniter function

public function login($email)
        {

                $password = $this->input->post('password');

                        $this->load->helper('string');
                        $this->load->model('user_model');
                        $this->load->library('session');

                        $user_status = $this->user_model->check_status($email, $password);

                        if (is_array($user_status) && $user_status['is_active']) {

                                $this->session->set_userdata('current_email', $email);

                                echo "success"; die();
                        }

                } die();

Answer 1

I can suggest an alternative: use the database as session handler.

You just need to enable it in the application/config/config.php file:

$config['sess_use_database'] = TRUE;

You need a table to store the saved sessions, the manual suggests using this schema:

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
    session_id varchar(40) DEFAULT '0' NOT NULL,
    ip_address varchar(45) DEFAULT '0' NOT NULL,
    user_agent varchar(120) NOT NULL,
    last_activity int(10) unsigned DEFAULT 0 NOT NULL,
    user_data text NOT NULL,
    PRIMARY KEY (session_id),
    KEY `last_activity_idx` (`last_activity`)
);

Other than this, you don't need to do anything, all the needed queries are handled by CI automatically, no change to be done in your actual code.

UPDATE:

A search on google led me to this CI forum thread (and this SO answer ). The cause might be safari caching the AJAX request, so you need to add a timestamp to the url and the issue should be resolved. Example:

var timestamp = new Date().getTime();    
$.ajax({
     url: site_url+"/user/login/"+email+"?"+timestamp, // Or use '/' instead of '?'

Answer 2

Is the ajax call sent to an external domain ?

If so, this might have something to do with security issues. See: http://drupal.org/node/918194

I have only dealt with this problem in IE, I don't know if this could happen on iOS.

So try adding the following on the ajax receiving side script:

<?php
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"'); 
?>

Note: make sure this header is put on all necessary pages and it occurs at the very beginning of your script.
