So how do you combine your favorite blogging app with your favorite framework so that user can signin from your cakephp app and maintain his/her session in wordpress, assuming user can only sign up and log in from your cakephp site.
The idea is to create a wordpress user when a user signs up on your cakephp site.
1. We need wordpress password hash function to do this properly. You need to create a new component that would contain wp password hashing functions. The file that contains everything you need is at wp-include/class-phpass.php. Just turn this class into a cakephp component, so you can include it in your user controller.
2. In your user controller, include your recently created wp hash function component. And after the user is saved into your cakephp user table. You want to add it to your wp user table as well. And it would look something like this.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110
if($this->User->save($this->data))
{
//create blog user for this user
$wp_hash = new $this->Wphash;
$wp_hash->PasswordHash(8,1);
$blog_user['ID'] = $this->User->id;
$blog_user['user_login'] = $this->sanitize_user($email);
$blog_user['user_pass'] = $wp_hash->HashPassword($this->data['User']['password']);
$blog_user['user_email'] = trim($email);
$blog_user['user_url'] = 'http://';
$blog_user['user_nicename'] = $this->data['User']['firstname'].' '.substr($this->data['User']['lastname'],0,1);
$blog_user['display_name'] = $this->data['User']['firstname'].' '.substr($this->data['User']['lastname'],0,1);
$blog_user['user_registered'] = date(configure::read('dateformat'));
$blogdata['Blog_user'] = $blog_user;
$this->Blog_user->save($blogdata);
//create user meta
$bid = $this->Blog_user->id;
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'first_name';
$user_meta['meta_value'] = $this->data['User']['firstname'];
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'last_name';
$user_meta['meta_value'] = $this->data['User']['lastname'];
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'nickname';
$user_meta['meta_value'] = $email;
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'rich_editing';
$user_meta['meta_value'] = 'true';
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'comment_shortcuts';
$user_meta['meta_value'] = 'false';
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'admin_color';
$user_meta['meta_value'] = 'fresh';
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
$user_meta['user_id'] = $bid;
$user_meta['meta_key'] = 'blog_capabilities';
$user_meta['meta_value'] = 'a:1:{s:10:"subscriber";b:1;}';
$blogdata['BlogUserMeta']= $user_meta;
$this->BlogUserMeta->save($blogdata);
3. In your wordpress index.php file
1 2 3 4 5
//change the session name of your wordpress site to match that of your cakephp site.
//so session data can be shared.
session_name("mysite");
4. in your theme header.php(might not be the best place if you change your theme a lot)
1 2 3 4 5 6 7 8 9 10 11 12 13
//you read the user id
$user = $_SESSION['Auth']['User'];
if(!empty($user))
{
//you change the current user manually
wp_set_current_user($user['id']);
}
And there you have it.

A definite great read….
Getting the error message Call to a member function save() on a non-object at the following line
$this->Blog_user->save($blogdata);
Any Idea?
that error message means Blog_user is not a model. you probably forgot to put BlogUsers in $uses array
Amazing article, lots of intersting things to digest. Very informative
Just a note for anyone else following this method. I had to set my session_name (and session_save_path) in my php.ini. It was ignored when I set it anywhere in WordPress.
Hi I have implemented the above method and also made the component and also saved the data in the WP table.Also declared the session_name(proslideware.com/test) but I am not able to get the session in my theme(proslideware) header.
It is giving error:
Notice: Undefined index: Auth in C:\wamp\www\psw\blog\wp-content\themes\proslideware\header.php on line 16
(When this was implemented on localhost:localhost/pws/blog)
Please tell me Is there anything wrong I am doing here?
defining the session_name location or what?
Wordpress is not at all getting my $_SESSION['Auth']['User'] data.
Please help!!!!!!!!!!
this is pretty old. might not apply anymore.
