Question

I’ve a website where the user have to add as much as he wants <input />, like:

Company: <input type="text" name="company[]" /> Participation: <input type="text" name="participation[]" />
Company: <input type="text" name="company[]" /> Participation: <input type="text" name="participation[]" />
Company: <input type="text" name="company[]" /> Participation: <input type="text" name="participation[]" />

In my PHP backend I check if all works, and I will also use jQuery Validation, but if something go wrong, how can I rewrite this dynamically added forms?

Thank you in advance!!!

I think I got it now. You can recreate the form elements with PHP. You get all the input values in $companies = $_GET['company']. It contains an array of values.

If you want to recreate the form elements, you can loop over this array (assuming you somehow sanitized the input), example:

<?php
// $companies and $participations should have the same length
$companies = $_GET['company'];
$participations = $_GET['participation'];

// sanitizing, validation
//...

$count = count($companies);
?>

<?php for($i = 0; $i < $count; $i++): ?>
    Company: <input type="text" name="company[]" value="<?php echo $companies[i]; ?>"/>
    Participation: <input type="text" name="participation[]" value="<?php echo $participations[i]; ?>"/>
<?php endfor; ?>
