Question

I have created a form that allows users to make a multiple choice quiz. The quiz can have up to 9999 questions and 99 options for each question (should they really need it), then store that quiz in a database.

My problem is that I cannot work out how to put the user created quiz in to the database. I know the mysql INSERT command, but cannot work out (or find) how to determine how many form inputs are being passed from one page to the next.

I would normally do:

$name = $_POST['name'];
$choices = $_POST['choices'];

$quizData = "INSERT INTO quiz
        (name, choices)
        VALUES
        ('$name',
         '$choices')"

But how do I do this without knowing how many questions and choices there are?

Since $_POST is an array, use foreach to set each question or answer into the database or into it’s own variable. If your fields are called questions, set them up like <input type='text' name='questions[]', you can then count how many questions there are in the $_POST[‘questions’] or whatever you call your questions fields array using count().
