html - PHP POST just not working for some reason -

trying make simple login page, here's form:

    <form action="admin/login" method="post" enctype="multipart/form-data">         <div class="input-container">             <span class="label">username:</span>             <input class="login-input" type="text" name="user" required>              <span class="label">password:</span>             <input class="login-input" type="password" name="pass" required>         </div>          <input id="login-button" type="submit" value="log in">     </form> 

here's login page:

<?php     ini_set('display_errors', 1);     ini_set('display_startup_errors', 1);     error_reporting(e_all);      echo $_post['user']; ?> 

i printed out:

notice: undefined index: user in /var/www/html/admin/login.php on line 6 

i have no idea going on , i've tried everything.

figured out, guys right issue .htaccess file.

i needed add slash after action path:

action="admin/login/" 

that's it!
