POST vs $_POST

Ok, so I passed this code challenge for PHP regarding posting the selected flavor to process.php. However I have no idea how... The two changes I made were changing form method to "post". I get that, although I'm not quite sure why it needs to be lowercase. But then can someone explain to me why adding name to the select statement makes it work? I guess I'm not thinking 2 dimensional here (columns and rows). I'm must still be thinking in terms of single dimensional text files...

<!DOCTYPE html> <html> <head> <title>Ye Olde Ice Cream Shoppe</title> </head> <body>

<p>Your order has been created. What flavor of ice cream would you like to add to it?</p>

<form method="post" action="process.php">

    <label for="flavor">Flavor</label>
    <select id="flavor" name="flavor">
        <option value="">&#8212; Select &#8212;</option>
        <option value="Vanilla">Vanilla</option>
        <option value="Chocolate">Chocolate</option>
        <option value="Strawberry">Strawberry</option>
        <option value="Cookie Dough">Cookie Dough</option>
    </select>

    <input type="submit" value="Update Order">

</form>

</body> </html>

In a real world scenario both method="POST" and method="post" would work because HTML is not a case sensitive markup language, lower case is simply the preferred W3C standard. The $_POST returns an array of everything that was posted, you access this by the name attribute $_POST['flavor']; without setting name="flavor" in your HTML, your $_POST['flavor']; wont exist.
