CodeIgniter's form_hidden

Question

How do I achieve this:

//view.php
<input type="hidden" name="Name" value="<?php echo $variable->id; ?>"

using CodeIgniter’s form_hidden helper:

//view.php
<?php echo form_hidden('Name','<?php echo $variable->id; ?>') ?>

The first one works fine when I display $variable->id but CI's form_hidden doesn't work.

Answer 1

The form helpers are evaluated when the script is run, just like any other script, so you do this:

<?php echo form_hidden('Name', $variable->id); ?>

If you have shorttags enabled, you could do:
<?=form_hidden('Name', $variable->id);?>
