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.

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);
}
I know i can get all segments from url like this
Lets say i have this example link
www.example.com/de/products.html
Using url_helper like this:
$data['url'] = $this->uri->uri_string();
I will get value like this
de/products
But i dont need first segment de, only products, the problem is that
i dont know how many segments it will be, i only need to remove the first
Is there possible to forget first segment with url helper in CI?
Try like this...
Use the php's explode() function to make the url string as array.Then apply array's array_shift() function which always removes the first element from array.
Code is looks like as below
$data= $this->uri->uri_string();
$arr=explode('/', $data);
array_shift($arr);
//print_r($arr);
Then use the php's implode() method to get the URI without first segment.Hope it will works...
$uri=implode('/',$arr);
echo $uri;
There is no URL helper in the CI to forget the first segment. However you can easily make a custom one and put #Hikmat's answer below it in the application/helpers/MY_url_helper.php in the Core folder.
e.g.
function my_forget_first_segment() {
$data= $this->uri->uri_string();
$arr=explode('/', $data);
array_shift($arr);
$uri=implode('/',$arr);
return $uri;
}
Before Edit answer.
You need to try this
$second_segment = $this->uri->segment(2);
From Codeigniter documentation -
$this->uri->segment(n);
Permits you to retrieve a specific segment. Where n is the segment number you wish to retrieve. Segments are numbered from left to right. For example, if your full URL is this:
http://example.com/index.php/news/local/metro/crime_is_up
The segment numbers would be this:
1. news
2. local
3. metro
4. crime_is_up
The optional second parameter defaults to NULL and allows you to set the return value of this method when the requested URI segment is missing. For example, this would tell the method to return the number zero in the event of failure:
$product_id = $this->uri->segment(3, 0);
example:
<?php
$data=$this->uri->segment(2);
$val=explode('.', $data);
echo $val[0];
?>
If I want to construct this url: /categories/5/update/?hidden=1 how could I pass both {id} param and hidden param (as GET) ?
My route is:
Route::get('categories/{id}/update', 'CategoryController#update');
I don't want to make a form and put it as POST because I have a number of buttons which simply hides/shows/removes a category and dont want to make a lot of forms for simple actions, although it has nothing to do with the question
I'm just a little bit confused, because it seems like action('CategoryController#update', [$id, 'hidden' => 1]) constructs the right URL but I got no idea how it's distinguished that the first one ($id) must be in URL and the second is a GET param
You may also try this to generate the URL:
$action = action('CategoryController#update', [id => $id]) . '?hidden=1';
Also, query string could be passed with any route even without mentioning about that in Route declaration.
I am trying to create a router which will take a dynamic value and forward it to the actual route. In normal case it would be like
$route['login'] = 'auth/login';
It is possible to catch a parameter before the login in the above parameter and pass it to as the first parameter to the actual route ? like
$route['^(.+)/login$'] = "$1/user/login";
Check out the documentation[docs]. There is a very easy way to do this.
$route['(:any)/login'] = '$1/auth/login';
Starx answer is correct but I wouldn't do that, as your first param will be your controller, and if you don't know what's in the dynamic value that's impossible to manage.
I would do :
$route['(:any)/login'] = 'user/login/$1';
This way, 'anything/login' would be redirected to your User controller, to the Login function with the parameter 'anything'.
Let's say I have a method at Controller named
book($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.
