PHP Doesn't post my form values - php

Question

I've been scratching my head for a hour now and can't figure out why php doesn't post my form values.
Code
<!-- Login -->
<div class="login__block toggled" id="l-login">
<div class="login__block__header">
<i class="zmdi zmdi-account-circle"></i>
Hi there! Please Sign in
<div class="actions login__block__actions">
<div class="dropdown">
<i class="zmdi zmdi-more-vert"></i>
<ul class="dropdown-menu pull-right">
<li><a data-block="#l-register" href="#">Create an account</a></li>
<li><a data-block="#l-forget-password" href="#">Forgot password?</a></li>
</ul>
</div>
</div>
</div>
<div class="login__block__body">
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="text" class="form-control" name="email">
<label>Email Address</label>
<i class="form-group__bar"></i>
</div>
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="password" class="form-control" name="password">
<label>Password</label>
<i class="form-group__bar"></i>
</div>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</div>
<?php
if(isset($_POST['login'])) {
if(isset($_POST['email']) && isset($_POST['password']) &&
is_string($_POST['email']) && is_string($_POST['password']) &&
!empty($_POST['email']) && !empty($_POST['password'])) {
$email = stripslashes(strip_tags($_POST['email']));
$password = md5($_POST['password']);
$stmt = $pdo->prepare('SELECT * FROM users WHERE UserEmail = :UserEmail');
$stmt->bindParam(':UserEmail', $email);
$stmt->execute();
if($stmt->rowCount() > 0) {
$stmt = $pdo->prepare('SELECT * FROM users WHERE UserEmail = :UserEmail AND UserPassword = :UserPassword');
$stmt->execute(array(':UserEmail' => $email, ':UserPassword' => $password));
if($stmt->rowCount() > 0) {
$row = $stmt->fetch();
$UserLevel = $row['UserLevel'];
if($UserLevel == 'banned') {
$display->ReturnError('Your account has been suspended.');
return false;
}
$UserID = $row['UserID'];
$time = time();
$IPAddress = $_SERVER['REMOTE_ADDR'];
$_SESSION['auth'] = $UserID;
$stmt = $pdo->prepare('INSERT INTO logs (LogUserID, LogDate, LogIPAddress) VALUES (:LogUserID, :LogDate, :LogIPAddress)');
$stmt->execute(array(':LogUserID' => $UserID, ':LogDate' => $time, ':LogIPAddress' => $IPAddress));
$display->ReturnSuccess('You was successfully logged in.');
$settings->forceRedirect('index.php', 2);
} else {
$display->ReturnError('Invalid user credentials.');
}
} else {
$display->ReturnError('User with these credentials does not exists.');
}
}
}
?>
</div>
Note that I'm very new to PHP and it would mean the world to me if you could help me out! Thank you.

Answer 1

Submit Button only works when it is inside form tag.
Your code does not have any form tag
Try this
<form action="" >
<!-- Login -->
<!--your code here -->
</form>

Answer 2

add form attributes like this
<div class="login__block__body">
<form action="url which will process form" method="POST">
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="text" class="form-control" name="email">
<label>Email Address</label>
<i class="form-group__bar"></i>
</div>
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="password" class="form-control" name="password">
<label>Password</label>
<i class="form-group__bar"></i>
</div>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</form>
</div>

Answer 3

All <input> tags must be within the <form> tags.
<form action="" method="post"> //Submits form to same page
<input/>
<input/>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</form>
When you "submit" this form, it will POST all of the input values within the form, which you retrieve from the $_POST['name_of_input'] variables
I would recommend learning HTML before PHP.
