A small helper function to compliment the existing form dropdown helper function. - El Forum - 06-14-2011

I discovered the documentation was vague on the arguments of the form_dropdown helper function about the item selected argument. I hoped for the best and fed it the display value of the entry I wanted as my default selection. Actually it goes off of the key instead. Since I'm working with rather long lists of option groups (196 countries by region) I needed something a little better. This is a first draft. It functions quite well as far as I've been able to test it.
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('select_search'))
{
function select_search($needle,$haystack)
{
$selected=array_search($needle,$haystack);
if ($selected) return $selected;
foreach ($haystack as $key => $val)
{
if(is_array($val))
{
$selected=array_search($needle,$val);
if($selected) return $selected;
}
}
return NULL;
}
}
?>I'm open for corrections and improvements.

First off, nice function.
One quick question though. Can you add an example usage?
Is it as simple as:
Code:
<?php
echo form_dropdown('name', $select_opts, select_search($my_text,$select_opts));

@theprodigy - Yep. Just that simple. Other than the need to load the helper file first. I didn't make any suggestions on that part, leaving it to the implementer how they wanted to name it.
