Calling a library from inside a helpers function in Codeigniter

Question

Can I load a library from inside a helper?

$this->load->library('name');

Thanks, Max

Answer 1

function sendEmail() {
     $CI =& get_instance();
     $CI->load->library('email'); // load library 
}

Answer 2

// ------------------------------------------------------------------------
/**
 * URL String
 *
 * Returns the URI segments.
 *
 * @access  public
 * @return  string
 */
if ( ! function_exists('uri_string'))
{
    function uri_string()
    {
        $CI =& get_instance();
        return $CI->uri->uri_string();
    }
}

Yes, of course.

I disagree with jimyi's answer. CI's own url helper loads the URI class.

Answer 3

No. The purpose of helpers is to "perform one specific task, with no dependence on other functions."

Quoted from CI's helpers page .

If you need to include a library inside of your helper, consider making it a library instead.
