drop downs, array syntax name, re-population - El Forum - 05-18-2010

My apologies if this has already been asked, but a quick search brought no results.
I have a drop down on my form, that beside that drop down is a '+' link that uses javascript to add another duplicate drop down. These drop downs have an array syntax name (like "actor[]").
I'm trying to figure out the best way to re-populate the drop downs when the form is re-shown due to a form error.
Does anyone have any good ideas?

You have to do a foreach loop and echo out each option element.
Code:
<select name="actor">
<?php foreaach($actor as $item):?>
<option value="<?=$item['value'];?>" <?=set_select('actor',$item['value']);?> ><?=$item['name'];?></option>
<?php endforeach;?>

I'm not talking about the number of options in a select, I'm talking about a dynamic number of selects.
Take a look at [link removed] to see what I'm talking about.
When you get there, click the + link next to actors. Another complete drop down will show up. When this is submitted, it is submitted as an array, because of the name of the elements ('actors[]').
If when the form is submitted, there is an error, and I need to repopulate the form, I'm trying to figure out the best way to tell how many selects to reproduce, and how to properly set each one.

ok, I think I got it. If there is a more effecient way of doing it, I'm all ears, but here is how I did it.
Controller:
the name of the element is 'actors[]', but I need to grab it by 'actors' (without the [])
Code:
$this->data['actors_submitted'] = array();
if($this->input->post('actors'))
{
$this->data['actors_submitted'] = $this->input->post('actors');
}Code:
<?php
if(! empty($actors_submitted))
{
$id = 1;
foreach($actors_submitted as $actor)
{
echo form_dropdown('actors[]', $actors, $actor, 'id="actor_' . $id . '"');
if($id == 1)
{
echo '<a href="#">+</a>';
}
if($id < count($actors_submitted))
{
echo '<br />';
}
$id++;
}
}
else
{
echo form_dropdown('actors[]', $actors, '', 'id="actor_1"') . '<a href="#">+</a>';
}
?>
