Codeigniter 4 testing when controller method not found - codeigniter

I am doing HTTP testing in Codeigniter 4 and am getting the following error:
CodeIgniter\Exceptions\PageNotFoundException: Controller method is not found
The reason for this is I am trying to call a get() method on a route that only has a post (switching it to add results in a different response). That is correct. I am trying to make sure that the page returns 404 if someone tries to hack it. The problem is Codeigniter doesn't assert Status is 404 it simply falls over. Here is my code triggering:
$r = $this->withSession($session)->get($url);
$r->assertStatus(404);
Note the assert never runs! Instead I get the original error message. Surely I should be able to check for 404 routes (I've tried '404' instead of int) ?? Yes I could set a custom route that allowed Get but I want to test it as-is rather than what it isn't.
How do I get CI4 to accept my incorrect route as a 404?

My solution is to define a constant (IN_TESTING) for when I am testing and then edit system/Codeigniter run() function. This is of course amending the core system which some people won't like but until there is a fix (I am using 4.1.2) then this will suffice.
catch (PageNotFoundException $e)
{
if (!defined('IN_TESTING') || IN_TESTING == false){
$this->display404errors($e);
} else {
$this->router = Services::router($routes, $this->request);
$path = $this->determinePath();
$controller = $this->router->handle($path);
$method = $this->router->methodName();
echo $path."\n".$controller."\n".$method;
exit;
$this->response->setStatusCode(404);
return $this->response;
}
}
Key tip if you do make changes to system files, track them! If you then need to run an upgrade you'll know what changes you've made.

Construct routes(urls) with slugs separated by dash in laravel

I am about to make more SEO-friendly URLs on my page and want a pattern looking like this for my products:
www.example.com/product-category/a-pretty-long-seo-friendly-product-name-12
So what are we looking at here?
www.example.com/{slug1}/{slug2}-{id}
The only thing I will care about from the URL in my controller is the {id}. The rest two slugs are just of SEO purpose. So to my question. How can I get the 12 from a-pretty-long-seo-friendly-product-name-12?
I have tried www.mydomain.com/{slug}/{slug}-{id} and in my controller to try and get $id. Id does not work. I am not able to able to separate it from from a-pretty-long-seo-friendly-product-name. So in my controller no matter how I do I get {slug2} and {id} concatenated.
Coming from rails it is a piece of cake there but can't seem to figure out how to do that here in laravel.
EDIT:
I am sorry I formulated my question very unclear. I am looking for a way to do this in the routes file. Like in rails.
You're on the right track, but you can't really logically separate /{slug}-{id} if you're using dash-separated strings. To handle this, you can simply explode the chunks and select the last one:
// routes/web.php
Route::get('/{primarySlug}/{secondarySlugAndId}', [ExampleController::class, 'example']);
// ExampleController.php
public function example($primarySlug, $secondarySlugAndId){
$parts = collect(explode('-', $secondarySlugAndId));
$id = $parts->last();
$secondarySlug = $parts->slice(0, -1)->implode('-');
... // Do anything else you need to do
}
Given the URL example.com/primary-slug/secondary-slug-99, you would have the following variables:
dd($primarySlug, $secondarySlug, $id);
// "primary-slug"
// "secondary-slug"
// "99"
The only case this wouldn't work for is if your id had a dash in it, but that's another layer of complexity that I hope you don't have to handle.
Route::get('/test/{slug1}/{slug2}','IndexController#index');
public function index($slug1, $slug2)
{
$id_slug = last(explode('-',$slug2));
$second_slug = str_replace('-'.$id_slug,'',$slug2);
dd($slug1, $second_slug,$id_slug);
}

why laraval routing return the object instead of echoing it or printing it directlly?

in laravel routing we can pass a closure and it returns the result. so my question is why it cannot echo or print the result than returning it?. is it the closurity property of php or laraveles routing rule.
Route::get('/',function(){
return 'hello world';
});
Because Laravel as a framework passes the result to other functions, for example to add headers to the response. This wouldn't work if you just echoed something there.

Codeigniter get parameters from url

I have a url "http://localhost/codeigniter/index.php/manual_export/". I need to get last segment from the url which is suppose to be a id. So for example "http://localhost/codeigniter/index.php/manual_export/2". I need to get the last segment which is "2".
I tired to use following code:
$id = end($this->uri->segment_array());
This works when I don't add "2" to the url and gives me "manual_export". However when I pass the id to the url I get an error "The page you requested was not found.". I think this is to do with routing. How can I fix this error.
the other way to do it is by defining a route, it will then be converted to a param
so for example if your controller is called manual_export and the method is getrecord
in the file application/routes.php
$route['manual_export/(:any)'] = "manual_export/getrecord/$1";
in your controller manual_export
function getrecord($id){ // etc etc }
You should use:
$this->uri->segment(n);//in your case n == 2 count starts just after index.php

Best practice in handling invalid parameter CodeIgniter

Let's say I have a method at Controller named
book($chapter,$page);
where $chapter and $page must be integer. To access the method, the URI will look like
book/chapter/page
For example,
book/1/1
If user try to access the URI without passing all parameter, or wrong parameter, like
book/1/
or
book/abcxyz/1
I can do some if else statements to handle, like
if(!empty($page)){
//process
}else{
//redirect
}
My question is, is there any best practice to handle those invalid parameters passed by user? My ultimate goal is to redirect to the main page whenever there is an invalid parameter? How can I achieve this?
Using the CodeIgniter routing in config/routes.php is pretty useful here, something like this:
$route['book/(:num)/(:num)'] = "book/$1/$2";
$route['book/(:any)'] = "error";
$route['book'] = "error";
Should catch everything. You can have pretty much any regular expressions in the routes, so can validate that the parameters are numeric, start with a lowercase letter, etc..
The best logic here seems to be adding the default values:
book($chapter = 1, $page = 1);
and then checking if they are numeric
So it automatically opens the 1st page of the 1st chapter if there are parameter missing or non-numeric.

Mutliple URL Segments to Index Function With CodeIgniter

Please excuse me if this is an incredibly stupid question, as I'm new to CodeIgniter.
I have a controller for my verification system called Verify. I'd like to be able to use it something like site.com/verify/123/abcd, but I only want to use the index function, so both URL segments need to go to it.
I'm sure this can be done with URL routing somehow, but I can't figure out how to pass both URL segments into Verify's index function..
Something like this in routes.php should do the job:
$route['verify/(:any)/(:any)'] = "verify/index/$1/$2";
I'm pretty sure you can just pass any controller method in CodeIgniter multiple arguments without modifying routes or .htaccess unless I misunderstood the problem.
function index($arg_one, $arg_two)
{
}
$arg_one representing the 123 and $arg_two representing the abcd in your example URI.
You will either need to edit the routes or write an htaccess rule, however i didn't understand why you want to limit to just the index function.
If you didnt wanna use routes for some reason, then you could add this function to the controller in question.
public function _remap($method_in, $params = array()) {
$method = 'process_'.$method_in;
if (method_exists($this, $method)) {
return call_user_func_array(array($this, $method), $params);
}
array_unshift($params, $method_in);
$this->index($params);
}
Basically it does the same as default behavior in CI, except instead of sending a 404 on 'cant find method', it sends unfound method calls to the index.
You would need to alter your index function to take an array as the first argument.
OR if you know that you only ever want 2 arguments, you could change the last 2 lines to
$this->index($method_in, $params[0]);
Of course both solutions fail in someone uses an argument which is the same as a method in your controller.
