Answer 1

Let's see what des doc says :

Loading a helper file is quite simple using the following function: $this->load->helper('name');

Where name is the file name of the helper, without the .php file extension or the "helper" part.

For example, to load the URL Helper file, which is named url_helper.php, you would do this: $this->load->helper('url');

It clearly suggests that CI will look for a file named xxx_helper.php. In you case, when load getdata, CI will look for getdata_helper.php inside application/helpers .

You just have to rename your file to make it work.
