Help with Ajax Dropdown List

RandomTom · 6 Aug 2009 at 17:55

I'm creating a 3 tier dropdown list to be called upon by PHP/Ajax similar to these two examples:

http://roshanbh.com.np/dropdown/

http://www.noboxmedia.com/demos/AJAX_country_area_list/index.php

Only problem is I don't know how to call the countries up without having them all listed in the HTML (which is less than ideal) This XML list tries to help:

But I'm struggling, being a bit of a newbie and all. Any help would be great, thanks.

You should store them in an php array then iterate through the array when building the html for the drop down.

So in the HTML call 'UK' for United Kingdom to come up? Saving a few characters is the best way rather than getting the list upon clicking the dropdown?

Thanks though.

You're better off using this: http://www.ustrem.org/en/articles/array-list-countries-en/

Then you can just loop through the array sequentially.

PHP:

<select name="countries">
<?php foreach($country_list as $country)
{
	echo '<option>'.$country.'</option>';
}
?>
</select>
