php- $_POST method does not work

Code:

<html>
    <body>
    Username: <input type='text' placeholder='Username' name='user' id='user' value='Nytrix'></input><br>
    Password: <input type='password' placeholder='Password'  name='pass'></input><br>
    <input type='submit' value='Login' name='submit'> </input><br><br>
    <?php
        echo $_POST['user'];
    ?>
</body>
</html>

Error: Undefined index: user<br>

It doesn't matter how i try to get the value from an input in will never get it. So my question is what am i doing wrong or why does it not work?

<?php  if (isset($_POST['submit'])) { 
echo $_POST['user'];
}
else
{
?>
<form  name="loginForm" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> 
 Username: <input type='text' placeholder='Username' name='user' id='user' value='Nytrix'></input><br>
    Password: <input type='password' placeholder='Password'  name='pass'></input><br>
    <input type='submit' value='Login' name='submit'> </input><br><br>
             <?php

}
              ?>

You need <form action="" method="post"> ... Inputs ... </form>. Then you have a form to submit.

for $_POST to exist, the current page must have posted. You don't post any data to this page. A way to achieve this is to add a form to your page, in which you can add your elements and submit button.

example (w3schools)

<form name="input" action="demo_form_action.asp" method="post">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>

ps: the input elements don't admin closing tags.

Try something like this:

 <?php
 if ( isset( $_POST['submit'] ) ) {   
    echo $_POST['user'];
 }
 ?>

You need to submit the form in order to have access to data inside $_POST . In your example you are accessing $_POST content without making sure there is a for submission. Once you click the submit button, the $_POST code will work.
