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];
?>

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 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

I am trying to do this route trick:
$route['cp/roles/:num'] = "cp/roles/index/:num";
but it doesn't work :(
please help me!!
advanced thanks .
According to the documentation on URI Routing:
$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
“A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.”
So, for your particular instance, you would do the following:
$route['cp/roles/(:num)'] = "cp/roles/index/$1";
You could try
$route['cp/roles/:num'] = "cp/roles";
and then instead of passing a variable in your function you use
$this->uri->segment(3);
or the number that correspond to the segment.
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.
How do I create an if statement saying something like this?
Basically, how do you use the URI class to determine if there is a value in any segment?
$segment = value_of_any_segment;
if($segment == 1{
do stuff
}
I know this is pretty elementary, but I don't totally understand the URI class...
Your question is a little unclear to me, but I'll try to help. Are you wondering how to determine if a particular segment exists or if it contains a specific value?
As you are probably aware, you can use the URI class to access the specific URI segments. Using yoursite.com/blog/article/123 as an example, blog is the 1st segment, article is the 2nd segment, and 123 is the 3rd segment. You access each using $this->uri->segment(n)
You then can construct if statements like this:
// if segment 2 exists ("articles" in the above example), do stuff
if ($this->uri->segment(2)) {
// do stuff
}
// if segment 3 ("123" in the above example) is equal to some value, do stuff
if ($this->uri->segment(3) == $myValue) {
// do stuff
}
Hope that helps! Let me know if not and I can elaborate or provide additional information.
Edit:
If you need to determine if a particular string appears in any segment of the URI, you can do something like this:
// get the entire URI (using our example above, this is "/blog/article/123")
$myURI = $this->uri->uri_string()
// the string we want to check the URI for
$myString = "article";
// use strpos() to search the entire URI for $myString
// also, notice we're using the "!==" operator here; see note below
if (strpos($myURI, $myString) !== FALSE) {
// "article" exists in the URI
} else {
// "article" does not exist in the URI
}
A note regarding strpos() (from the PHP documentation):
This function may return Boolean
FALSE, but may also return a
non-Boolean value which evaluates to
FALSE, such as 0 or "". Please read
the section on Booleans for more
information. Use the === operator for
testing the return value of this
function.
I hope my edit helps. Let me know if I can elaborate.
