Not sure if this is what your looking for, next time try to explain your problem better
so that we can understand what you are looking for.

You can add this to your controller etc;

PHP Code:

    /**
     * isChecked ()
     * ---------------------------------------------------------------------------
     *
     * $chkBoxName  - The name  of the form checkbox or radiobutton 
     * $chkBoxValue - The value of the form checkbox or radiobutton
     * 
     * EXAMPLE:
     * 
     * $formValue = $this->isChecked('chkBox1', '1');
     * 
     * @param  $chkBoxName  - the input name you set
     * @param  $chkBoxValue - the value that you set 1 0 yes no etc;
     * @return bool
     */
    function isChecked($chkBoxName, $chkBoxValue)
    {
        if ( ! empty($this->input->post[$chkBoxName]))
        {
            foreach ($this->input->post[$chkBoxName] as $chkBoxVal)
            {
                if ($chkBoxVal == $chkBoxValue)
                {
                    return true;
                }
            }
        }

        return false;
    } 


NOTE: A checkbox or radiobutton does not return any value when they are unchecked!
You may need to change it to 0 if you get a false returned from this method.

What did you Try? What did you Get? What did you Expect?
