Dynamically add forlm fields 1

[mcquam]

I have a form where one of the fields can have an unknown number of inputs. I need a way for php to count the fields that have been populated and offer a blank field if required. I currently have 20 input fields like this:

	<li><input type="text" name="ingredient[]" id="ingredient_1" size="80" value="<?php if (isset($_POST['ingredient'])) echo $_POST['ingredient']; ?>" /></li>

So I am looking for a way to create the list from the array field and also to presumably have the form to submit only the ingredient fields.

Assuming I understand what you need, PHP can't interact with the client, so there is no way for it know when a field has been populated. Unless the form is submitted to it.

You would need Javascript to check that all fields have been used and then have it create the additional field.

I concur with vacunita. You will need to submit the form and react appropriately or you will need Java Script (a client-side service) to monitor field content and populate more as needed.

I thought it might be possible to make the form sticky and present it with an additional field each time?

Thanks, I've managed to do it with jquery.
