how to login/ logout ?!


Recommended Posts

Dear all,

A beginner here. When I went to this link:http://processwire.com/api/user-access/ to find out how to make login/ logout pages, nothing showed up. Any tutorial regarding this topic for guidance? I'd like to have two different groups of users and each goes to certain different pages after login. When they are logged out, both can see some general pages. Probably there is a very basic answer but I am not an advanced web programmer. Help me out, please  :undecided:  Thanks

Hi circlet, welcome to ProcessWire!

How is your current setup for the users? I Assume you created two different roles to distinguish them and assigned one of them to your users.

You can log-in a user with the API: http://processwire.com/api/variables/session/

Short example:

/* After the form with username/password was sent... */

// Log in the user
$username = $sanitizer->pageName($input->post->username); //Sanitize username
$u = $session->login($username, $input->post->password);

// Check if a user was returned or null
if (!is_null($u)) {
  // Redirect based on role
  if ($u->hasRole('role-A')) {
} else {
  // Wrong username or password

You're welcome!

Yes exactly. It's the same as getting the values from  php's $_POST array, but it's a nice "Pw-way" of doing it :)

Plus you get the advantage that if a variable is not set, $input returns null whereas accessing a variable that does not exist in the $_POST array returns a Notice "undefined index".

Thank you, Wanze!

I think I got it in a way. I was afraid no one would reply such a noob question. But you guys are so responsive, you rock :lol: Sometimes, even a tiny little thing would not make a sense and you have to ask someone else who knows. Such a welcoming community. I'll explore PW more and will make this website. Thanks again.

Yes, PW Community and especially Ryan helping with tipps and code examples :)

Ryans login example, a modified version from renobird. Another version from Ryan with login, reset password and profile.

Haven't used the examples yet, but maybe in the near future.

But why nobody write a login module to have a shared base for all? Should be great for new users to get started ;)

      I’m new to Processwire. I’ve installed the current release version at my very-long-time (25 years) host, pair Networks. MySQL db is created. Installation process completed with no errors.
      I’m now trying to log in. Rather than taking the default `/admin` suggestion, I chose `/xyzzy`. When I go to `example.com/xyzzy`, PW displays a login screen, as expected. I enter the username (`xyzzy`) and password that I assigned (and copied and stored in 1Password) in the installation process (five words separated by hyphens). So far, so good.
      I would expect then to be taken to the admin pages. Or (if I got something wrong) to be given an error message. Instead, I’m taken to the URL `example.com/xyzzy/page/?login=1`, which as far as I can tell is exactly the same as the initial login page. No error is given.
      I grew so frustrated by this, that I deleted the entire installation and the MySQL database, re-downloaded PW, installed it again using a different username and password for the admin account.
      And I’m seeing exactly the same behavior. Time for me to ask you experts: WTF?
      Many thanks for any insights you may have....

      I'm still new at processwire, i want to ask, i was create a website with sign in system, but i want to add a access roles/permission for each user at my website. For now, i just can create a login user without any permission and the user data became as a pages in my processwire.
      Here i attach my code for login
      <?php $note = $note2 = $hidden =""; if($input->get->id == "logout") { $session->remove('login_id'); } if($input->post->submit) { $email = $sanitizer->email($input->post->email); $pass = $sanitizer->text($input->post->pass); $result = $pages->find("email=$email, text_1=$pass"); if(!$email || !$pass) { $note = "Data belum lengkap"; } else { if($result->count > 0) { $session->login_id = "$result"; $hidden = "style = 'diplay:none'"; $url=$pages->get("/files/")->httpUrl; header("Location:$url"); die(); } else { $note = "Akun tidak ditemukan"; } } } ?> And this code for login form
      <div class="frow-container"> <div class="frow centered mt-50"> <div class="col-md-1-3"> <div class="box p-40 shadow-light"> <h2 class="mb-20 text-center" <?=$hidden?>>Database Partitur<br>GII HIT</h2> <form method="post" <?=$hidden?>> <label>Username <input type="text" name="email"></label> <label>Password <input type="password" name="pass"></label> <input type="submit" name="submit" value="Masuk"> </form> <p class="notif"><?=$note;?></p> <div class="text-center"><?=$note2;?></div> </div> </div> </div> </div> Just for remember, my user data now is a pages, and i cannot give any permission to user data.
      Thank you very much for help.

      I need users to login by their email address. This works when I change the value in ProcessLogin.module
       122     protected $useEmailLogin = null;
      122     protected $useEmailLogin = true;
      What would be a recommended way to enable this?
      There's this line in ProcessLogin.module:
        15  * @property bool|int $allowEmail Whether or not email login is allowed (0|false=off, 1|true=Yes, 2=Yes or name also allowed)
      But I can't figure out how to set this. I tried next to $useEmailLogin in ProcessLogin.module and in config.php, but neither takes effect.
      BTW I tried module LoginWithEmail but it seems outdated. My PW version is 3.0.165

      Hey folks,
      Iam working on a new Admin Theme, based on AdminThemeReno, which I would like to release for the public soon.
      Now I want to style the login page to fit the look and feel of the backend.

      After some research, I found out that I have to set the "$config->defaultAdminTheme = 'AdminThemeName' " inside my site config.php file to load all the styles from my admin theme on the login page instead of the default ones.
      Is it possible to set this via api from my Admin Theme settings, without the need of editing the config file?

      Hi. I'm currently stuck at the login page in my project. Once I enter my admin username and my password and press login, nothing happens. The page just reloads. However, the URL changes from http://myipaddress/processwire to http://myipaddress/processwire/?login=1. I've checked all of my server settings, and to my knowledge, all seems to be fine there. I don't know where to go from here.. Thanks in advance!
