根据URI段进行重定向

Question

I am using Codeigniter and want to have SEO-friendly URLs. There will be 2 types of URI segments, http://www.domain.com/view/193847 and http://www.domain.com/view/193847-canon-5d-mark-iii .

If the first URL is used, function view_mini is called and passed the product id 193847 . If the 2nd one is used, function view_full will be called and passed the same product id 193847 .

Problem: How can I differentiate between the 2 URLs? Or is this an inferior approach to solve the problem?

PHP How should the if condition be structured?

function view($pid) {
    if($this->uri->segment(2) == something) {
        $this->view_mini($pid);
    } else {
        $this->view_full($pid);
        }
}

function view_mini($pid) {
   // ...
}

function view_full($pid) {
   // ...
}

EDIT

I am using URL routing to route http://www.domain.com/controllername/view/1234 to http://www.domain.com/view/1234

Answer 1

Edit: un-tested

$route["view/(\d+)"] = "class/view_mini/$1";
$route["view/(\d+)-([\w'-]*)?/g"] = "class/view_full/$1/$2";

Answer 2

Is there any definitive structure to the different URLs?

ie.

http://www.domain.com/view/[numbers]-[text]

If so, you could test the URL for that dash between the numbers and the dash?

Answer 3

you can use the regular expression to check the segment if it has anything other than numbers, then you can execute the view that you want for example

$pattern = '\d[0-9][^a-zA-Z]';
$url = $this->uri->segment(2);
if(preg_match($pattern,$url))
{
//this will match only the numbers

$this->view_mini($pid);
    } else {
        $this->view_full($pid);
    }

i hope this will help ..

Answer 4

Use

$result = explode('-', $this->uri->segment(1));

If(isset($result[1]))
{
    // show full view
} else {

    // show mini view

}

$pid will always be $result[0]
