如何在使用Codeigniter配置路由时检查Controller是否已存在？

Question

On my website, I am loading the content dynamically from database like this

e.g mysite.com/about-us   

for this, there is an enrtry in database, so it will load the content for 'about-us' & print it using "page" controller only.

for this what I have done is, I have added below configuration in routes.php

$route[':any'] = "page";

but lets say if I already have controller named "about-us" and I want to load that & not the one from database, how can I do that?

Answer 1

A smooth solution would be to use the error/missing_page controller and point it in the config/routes.php .

Then it would automaticly pick all existing controllers first, and then that controller.

You can also call show_404() if you don't find a record in the database.

This allows you to create new controllers without having to point all of them in the route file.

Read about 404 override here

Answer 2

you need to add this

$route['about-us'] = "aboutus";
$route['about-us/(:any)'] = "aboutus/$1";

before

$route[':any'] = "page";

as the CI route is not greedy, it will not check for the page controller after it finds the about-us controller.
