PHP MySQLi Prepared Statement Not Working [closed]

Question

EDIT START

So I found the issue with my code. It was the following line

if(isset($_REQUEST['faq_submit'])) {

I am not sure whats wrong with this line? Why wouldn't it be working properly?

EDIT END

For some reason my prepared statement isn't working. Also it doesn't seem to be displaying any errors in the error log. Now I am probably just doing something wrong there but I am sure someone here could spot something wrong I did haha... I tried fixing it in a couple different ways and was just unsuccessful so asking here for help is always a good resort!

Here is the my php code for adding a question

// Required Configuration
include_once('required.php');

// double check page was accessed via submit button
if(isset($_REQUEST['faq_submit'])) {
    // get data that sent from form
    $topic=trim($_REQUEST['faq_topic']);
    $detail=trim($_REQUEST['faq_detail']);
    $name=trim($_REQUEST['faq_name']);
    $email=trim($_REQUEST['faq_email']);

    // check if all forms are filled out
    if(!empty($topic) && !empty($detail) && !empty($name) && !empty($email)) {
        // Validate Email
        if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
            // Prepared Insert Statement
            $stmt = $mysqli->prepare('INSERT INTO forum_question (`topic`, `detail`, `name`, `email`, `datetime`) VALUES (?, ?, ?, ?, ?)');

            // Bind Variables To Values
            $stmt->bind_param('sssss', $topic, $detail, $name, $email, $datetime);

            // Execute Prepared Statement
            $stmt->execute();

            // Print Results
            $html = '<div class="alert alert-dismissable alert-success"><button type="button" class="close" data-dismiss="alert">×</button>You <strong>successfully</strong> submited a question to the FAQ bored.</div>';
            print($html);

            // Close Connections and Statement
            $stmt->close(); // Statement
            $mysqli->close(); // MySQLi
        } else {
            // Email Validation Failed
            $html = '<div class="alert alert-dismissable alert-danger"><button type="button" class="close" data-dismiss="alert">×</button>Your <strong>email</strong> was invalid.</div>';
            print($html);
        }
    } else {
        // If the required items were not filled out print the following
        $html = '<div class="alert alert-dismissable alert-danger"><button type="button" class="close" data-dismiss="alert">×</button><strong>All</strong> forms are required.</div>';
        print($html);
    }
}

Here is that required.php file although I have removed some of the login info.

$datetime=date("m/d/y h:i"); // Format Date And Time

// Connect
$mysqli = new mysqli('host', 'user', 'pass', 'db');

// Check Connection
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

Have you tried checking if any statement errors are being thrown? http://www.php.net/manual/en/mysqli-stmt.error.php
