codeigniter display warning error if argument in URL not provided
just learned that the solution is simple:
function id($id=NULL){ if ($id===NULL) { redirect.... }}
you can also use:
$this->uri->segment(2); // gets 'id'$this->uri->segment(3); // gets '45'then do a redirect, check out:
http://codeigniter.com/user_guide/helpers/url_helper.html
use default values for your function
function id($id=0){ if(there any record with $id being provided){ //do something}else{ //id not provided,set to default values 0 and then show_404(); }}no way there could be id = 0 so its automatically showerror without redirect, if user enter the url www.example.com/profile/id ,
