将URI段传递到Codeigniter函数中

Question

Let's say I have a view method that receives a variable via the URI.

ex. http://www.domain.com/item/view/200

Does it make sense to turn the incoming variable into the correct type? In this case, making $item_id into int which is what is expected.

For example, in the controller ...

function view($item_id) {
    if ( $this->item_model->checkItem( (int) $item_id )) {
    ...
    }
}

Answer 1

Yeah, casting the variable as integer like you are doing is OK.

And the way to pass the segment into function is like

$segment = $this->uri->segment(2); //get the second segmention
           // ^ You can send a default Values as well if itemid is not set
           // Like: $this -> uri -> segment(2, '0')
//now pass it to the function you need
