CodeIgniter URL使用RegEx数字和字母表进行路由

Question

I need a RegEx for arguments that combines numbers(0-9) and alphabets(a-z or A-Z).

Here is my route

$route['(:any)/PhotoDetails/(:any)'] = 'profile/PhotoDetails/$1/$2';

Answer 1

Possible regx are:-

$route['([\w]+)/PhotoDetails/([\w]+)'] = 'profile/PhotoDetails/$1/$2';

but there is a flow in above expression it could accept "_" as well since your routes contains only alphanumeric charactors so please use following route.

$route['([a-zA-Z0-9]+)/PhotoDetails/([a-zA-Z0-9]+)'] = 'profile/PhotoDetails/$1/$2';
