Is there any tutorial that will show how to display database record without without pressing the submit button? For example, <select name="cars"> <option value="">Select a car:</option> <option value="1">Volvo</option> <option value="2">BMW</option> ... > </select> In this example, the user will select anything from the list and should automatically display the information based on the selection.
