title: Auto Incrementing HTML Form ID's in input field
body: <p>How does one auto-increment Id's to an HTML form so it's easier to classify? Kind of like an invoice/reference number? In other words, is it possible to create an hidden input field that would attribute a serie of numbers and also an ID automatically when the form page is loaded just like in Mysql for instance? The idea here is to make that happen for a form.</p>
