<form action="../includes/process_login.php" method="post" name="login_form">   
                    <div class="form-group">
                        <label class="control-label">Username</label>
                        <input type="text" class="form-control" name="username" />
                    </div>
                    <div class="form-group">
                        <label class="control-label">Password</label>
                        <input type="password" class="form-control" name="password" />
                    </div>
                    <div class="text-center">
                        <input type="button" 
                           value="Sign in" 
                           class="btn btn-primary" 
                           action="../includes/process_login.php"/> 
                    </div>
                </form>

Hello all, I have been following a tutorial and stumbled upon this error. Whenever I try to click the Sign-in button, it doesn't re-direct me. It is supposed to log me in.

Thank you in advance.

Remove the "action" from input and change its type to "submit".

<input type="submit" value="Sign in" class="btn btn-primary" /> 

This will submit the form to "../includes/process_login.php".
