Use hyphen(-) instead of slash(/) or underscore( _ ) in Routes

问题

I'm Using Codeigniter 3.x , Using routes.php I want to create dynamic routes, for example I have a class name Class1.

I want output url

mysite.com/Class1-Student-Search

But using hyphen(-) is not working

If I put a slash(/), it works,

$route['(:any)/Student-Search']  = "search";

it returns

mysite.com/Class1/Student-Search

and using underscore (_) also work.

$route['(:any)_Student-Search']  = "search";

returns

mysite.com/Class1_Student-Search

But I want to use hyphen(-), if I put it, it will go to 404 error page, I used these four solutions but not work for me.

$route['(:any)-Student-Search']  = "search";
$route['([a-zA-Z]+)-Student-Search']  = "search";
$route['([a-zA-Z-0-9]+)-Student-Search']  = "search";
$route['(.*)-Student-Search']  = "search";

And if i hardcode the value in route

$route['Class1-Student-Search']  = "search";

Then it also working

回答1:

You trying to create a dynamic routes which is not possible in codeigniter if you see the following flow chart of codeigniter you understand what i mean.

also you can see this chart in codeigniter official website

when you try to redirect or call some url it's work like this

Every request first goes to route there for you can't make it dynamic

Here is my solution, it is working for me, do like this.

$route['(:any)-Student-Search']  = "search";

then in your link button, hopefully in your view, href the link like this.

href="/<?php echo $row->classname; ?>-Student-Search"

the point is that not only you have to make your routes, also suffix it in your href link also the same way.
