Codeigniter路由不适用于正则表达式

Question

I am trying to check if a url is in given format by using regular expression. this is my code.

myurl is : example.com/123456-watch-example_video_name

$route['([0-9]+)-[watch]-[A-Z0-9_+-]'] = 'mycontroller';

It is going to 404 page. Where I am wrong, i am new to regular expression.

Answer 1

Try the below:

$route['([0-9]+)-watch-[A-Z0-9_+-]+'] = 'mycontroller';

[watch] matches one char of watch , so remove [] , and [A-Z0-9_+-] matches one char too, for one and more use [A-Z0-9_+-]+
