Can anyone suggest a PHP solution to creating a form that gets built after a client enters a variable? For example: an automobile insurance form that first asks how many cars you have, and then creates a form with fields for car 1, car 2, etc.
I have found JavaScript code that will do this, but I would rather use a server side language like PHP for more consistency and browser compatibility.
step1.php --- <form action='step2.php' method='post'> How many cars do you own? <input type='text' size='2' name='numberOfCars'> <input type='submit'> </form> ---
step2.php
---
<form action='step3.php' method='post'>
<?
$i=0;
while($i < $_POST['numberOfCars'])
{
$i++;
echo "<h2>car number {$i}</h2>";
echo "Make <input type='text' size='50' name='car[{$i}][\"make\"]'><br>";
echo "Model <input type='text' size='50' name='car[{$i}][\"model\"]'><br>";
echo "<hr>";
}
?>
<input type='submit' />
</form>
---
This will produce an array of cars ($car[1] to $car[n]), each of which is an array of two elements make and model. Haven't done any work with arrays? Now is a good time :)
step3.php --- <pre><? print_r($_POST) ?></pre> ---
This code is there just to show you the array structure... you'd change it to ad items to a database, etc.
Example output:
---
Array
(
[car] => Array
(
[1] => Array
(
["make"] => datsun
["model"] => 1600
) [2] => Array
(
["make"] => toyota
["model"] => corolla
) [3] => Array
(
["make"] => honda
["model"] => civic
))
) ---
Good luck :)
