form open

I have a question will form open always using post method?

For example:

echo form_open('email/send');

the same thing like:  <form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send">

What if I want to use get method?

" If I looks more intelligence please increase my reputation."

In system/helpers/form_helper.php:

PHP Code:

    function form_open($action = '', $attributes = array(), $hidden = array())
    {

//some codes here
        $attributes = _attributes_to_string($attributes);

        if (stripos($attributes, 'method=') === FALSE)
        {
            $attributes .= ' method="post"';
        }


//some codes here

    } 


As you can see you can set method using $attributes array
