Laravel case insensitive routes

Question

How do I define a case insensitive (part of a) route?

Example:

• Route::get('/{userId}/profile');
• http://domain.com/123/profile works fine.

Any use of uppercase in the fixed part of the route does not work:

• http://domain.com/123/Profile does not work
• http://domain.com/123/proFILE does not work

I understand how I can make parameters like {parameter} use a regex pattern using ->with(), but that does not help me with the fixed part of the route, like described above.

Answer 1

This can be solved by defining routes the following way:

Route::get('/{userId}/{profile}')->with('profile', '(?i)profile(?-i)');

Even smarter, define it as pattern, then it also becomes available in Route groups.

Route::pattern('profile', '(?i)profile(?-i)');
Route::get('/{userId}/{profile}');

For those using Apache you could also do this:

At this the top of your vhost file add

RewriteEngine On
RewriteMap lowercase int:tolower 

and in your .htaccess

RewriteCond $1 [A-Z]
RewriteRule ^(.*)$ /${lowercase:$1} [R=301,L]

Answer 3

Adding patterns only works on one route at a time, if you want all routes to be case insensitive add this to your /app/filter.php file in the before section:

I wrote a gist which does this: https://gist.github.com/samthomson/f670f9735d200773e543

Edit your app/filters.php to check for uppercase characters in the route and redirect them to a converted route.
