My login screen form HTML login.html ):
<form class="form-signin" method="post" action="login.php">
<span id="reauth-email" class="reauth-email"></span>
<input type="email" name="user" id="user" class="form-control" placeholder="Email address" required autofocus>
<input type="password" name="password" id="password" class="form-control" placeholder="Password" required>
<div id="remember" class="checkbox">
<label>
<input type="checkbox" value="remember-me"><div class="remb">Lembrar-me</div>
</label>
</div>
<button class="btn btn-lg btn-primary btn-block btn-signin" type="submit" value="submit">Sign in</button>
</form><!-- /form -->
When I click the submit button, having typed an email and any password, the browser offers me to open a php file, when I open it, it has the code present in the file login.php . No matter what's in that file.
