If you use Smarty as your template engine in CodeIgniter you may find this useful for generating form tags.
Usage:
Regular form
{form url='module/function'}
<input type="submit" />
{form}
Upload Form
{form url='module/function' type='upload'}
<input type="submit" />
{form}
Note:
if you use {form} without the url parameter this will close the form.
Installation
Create a file “function.form.php” in Smarty-x.y.z/libs/plugins where x.y.z are the version number of Smarty.
