Matching variables with url parameters in nodejs & express - ajax

This is really just a conceptual question as I am a beginner to nodejs and express. So basically I would like to have a route that is something along these lines:
Controller
app.get('/explore/:qID?', siteRoutes.explore);
Routes
exports.explore = function(req, res){
...
};
So the way I wold like to have this happen is to pass a variable called qID to the controller using an ajax call. Is there any way that I can take that variable and inject it into the route? My wording is confusing, probably. Basically I want to be able to go to url.com/explore/5 and have that display the corresponding question (qID). Is this the correct way to go about this?

Take a look at req.param in the express docs.
http://expressjs.com/api.html#req.param
basically your route will look like this
app.get('/explore/:qID', siteRoutes.explore);
You can access the qID like this:
var qID = req.param('qID');

Laravel - How do I navigate to a url with a parameter to left of subdirectory

I have to test this Route, but I am not sure how to navigate to it.
Route::get('/{type}/Foo/{page}/{date}', 'FooController#index');
I understand that URLs usually have subdirectories defined before the parameters in the URL.
I have worked with URLs like this example
Route::get('/Foo/{type}', 'FooController#index');
which would have an endpoint that looks like
/Foo?type=bar
Does anybody know how to test a route such as the one above?
Well i think that you need to clear out a bit the difference between route and query parameters.
In your case you are trying to use route parameters which will actually look something like:
/{type}/Foo/{page}/{date} => /myType/Foo/15/12-11-2021
Laravel considers the words inside {} as variables that you can retrieve via request so you can do something like:
$request->type
and laravel will return you the string myType as output.
In your second case that you have tried in the past you are referring to query parameters which are also a part of the $request. Consider it as the "body" of a GET request but i don't mean in any way to convert your post routes to GET :)
The thing with your second url is that:
/Foo/{type} is not similar to /Foo?type=bar
instead it should be like: /Foo/bar
In general query parameters are when you want to send an optional field most of the times in your GET endpoint (for filtering, pagination etc etc) and the route parameters are for mandatory fields that lead to sub-directories for example /Foo/{FooId}/Bar/{BarId}
The thing to remember is that you must be careful about your routes because variables can conflict with other routes.
For example a route looking like this:
Route::get('/foo/{fooId}', [FooController::class, 'getFoo']);
Route::get('/foo/bar', [BarController::class, 'getBar']);
will conflict because laravel will consider bar as the variable of the fooId so your second route can never be accessed.
The solution to this is to order your routes properly like:
Route::get('/foo/bar', [BarController::class, 'getBar']);
Route::get('/foo/{fooId}', [FooController::class, 'getFoo']);
So when you give as a route parameter anything else than bar your will go to your second route and have it working as expected.

codeigniter with same route name with different controller functions

I want to keep routes like this
$route["signup"] = "Controller/signup";
$route["signup"] ="Controller2/fbsignup";
Is it possible to to give same route names with different controller functions.
Then how ?
No, you can't.
If you write same route again, it will overwrite first one.
It is just like an array variable.
If you assign any other value to variable, first one will overwrite.
But you can specify HTTP method with route.
No you can't do like this, you are going to make api then define method that will help
$route["signup"]["post"] = "Controller/signup";
$route["signup"]["GET"] ="Controller2/fbsignup";
I want to keep routes like this
$route["signup"] = "Controller/signup";
$route["signup"] ="Controller2/fbsignup";
then try this in routes and url should be like signup/signup and signup/fbsignup
$route["signup/signup"] = "Controller/signup";
$route["signup/fbsignup"] ="Controller2/fbsignup";
call the url like
signup/signup
signup/fbsignup

Codeigniter router get parameter

I use $.getJSON() to retrieve some data for a couple of cascading dropdowns in my form. $.getJSON() automatically appends the parameter at the end of the URL like domain.com/controller/method/?parent=5
So, I've declared my method like public function method($parent) which works file, but the same method will be used from other parts of the website that will call it like domain.com/controller/method/5
I tried to create a route in routes.php like the one below:
$route['business/regions/?parent=(:num)'] = 'business/regions/$1';
but it doesn't seem to work. Am I doing something wrong? Maybe ? is confusing the regex parser of the router? Do I have to escape it somehow to make it a 'literal' ? ?
Or is it that router is not used to 'rewrite' get parameters at all? I'm very confused, as it should work but it doesn't and I'm wondering what's wrong with it...
Codeigniter route parameters are for url parameters. It is particularly useful when trying to create a REST styled url pattern.
What you're trying to do is get url query string from the url which is not supported via the Codeigniter router. For you to get what you want you can do the following:
In your routes.php:
$route['business/regions'] = 'business/regions';
and in your controller Business.php:
public function regions() {
//the numeric id you're looking for
$parent = $this->input->get('parent');
}

How to run single controller method from any route in Laravel 4

I really hope my question has been well thought out but here goes.
How do you implement something like
Route::get("/url1", "controller#method");
Route::get("hello/url1", "controller#method");
Route::get("hello/hi/url1", "controller#method");
in Laravel but using something like
Route::get("*/url1", "controller#method");
instead of declaring every route path?
I will explain why this problem has come up. You see the primary url is always changing because its being called from a js file via a location.href call. I could decide to use a primary url variable but its to be deployed via intranet to different servers in organizations and the primary url could change at any time meaning that localhost/project on one system might become localhost:7987/project on another thus breaking the url variable, now thats on one part. On the other hand there are js functions running continuously and when someone navigates to a deeper url, say from localhost/home to localhost/home/event a route call that should be independent of folder breaks
So yeah, I am wondering if theres a way to declare a global route that points to a controller and/or if this is possible in Laravel.
Thanks
Try this:
Route::get('{something}/url1', 'controller#method')->where('something', '*');
Not sure if that will work, but the idea is that you can use where to pass some Regexp to match selected value from route.

How to pass URL parameters to a joomla module

I have my own nice link http://www.link.com/sometext, now I would "enhance" this having the opportunity to write something like http://www.link.com/sometext?parameters=myParam cause I need to send a parameters to the article called by sometext.
Can I do something like that??? How can I pass parameters through the URL???? How can i get it's value?
Regards
You should use the standard Joomla way to retrieve GET/POST requests. This link should get you started:
http://docs.joomla.org/Retrieving_data_from_GET_and_POST_requests
$address = JRequest::getVar('address');
EDIT - just saw your other comment. To use PHP inside article, try something like Sourcerer: http://extensions.joomla.org/extensions/edition/custom-code-in-content/5051
