I have a plugin and i need to load a different routing.yml file based on a variable in the query string.
Example:
if($request->getParameter('page'){
// use routingPage.yml
}
else{
// use another routing.yml
}
So, If the page parameter in url the url_for('#route1'), will return one url, else the same url_for('#route1') would return other url.
How can override the rouing.yml loading mechanism to do what I want?
Every application can have only one routing.yml (of course it can be overrided by other plugins).
The reason for this is quite simple: If you want to use multiple routing files (say routing1.yml and routing2.yml), and they both have a route called route1, which redirects to controller1/action and controller2/action respectively.
Maybe you would be able to switch it in the view, and go to controller1/action in the one case and controller2/action in the other. But then: when a new request arrives, and the front controller is determining which controller / action to execute: how does it now which routing.yml to use?
So I don't know exactly what you're trying to achieve, but I would go for two routes in your routing.yml, and select the route based on your view parameters.

If I have the following piece of code
script.
function getProductParams(params) {
return JSON.parse(localStorage.getItem(params));
}
each product in products
-var getVariable = getProductParams("ids");
This piece of code doesn't work, I'm guessing that - is on server side, while script. is on clients?
How can I access a variable from localStorage in pug and use it for comparison with variables received from server.
I want to make something like this
script.
function getProductParams(params) {
return JSON.parse(localStorage.getItem(params));
}
each product in products
-var getVariable = getProductParams("ids");
-if (getVariable.includes(#{product._id}) {
// create the element in html
-} else {
- // call next product and compare if we have it
-}
The simple answer is that you can't do this. LocalStorage is exactly that - local. Your server can't directly access it unless you explicitly pass it back using some other format/method.
What your server can access easily is the cookie. If you store the data in the cookie and use cookie-parser then you can handle this list quickly. This use case is exactly why cookies exist.
Another option would be to pass the data to the server in the body of a POST request, but your question doesn't provide a lot of information as to what exactly you're doing and if this is an option or not.
It would also be much easier for you to accomplish all of the sorting and filtering in your route instead of the pug template. That way you have full request to the cookie, request body, etc. directly and you don't have to pass that down to the template too.
Then, when your template gets the list it's a really simple matter to render it:
each product in products
//create the element in html
I'm making a web app where users can create pages, edit them, and delete them. In developing the prototype, I have a user access a route such as:
localhost:8000/mypage/1
The "1" in the URL refers to the ID in the database, so that the controller can fetch the appropriate associated data and populate the page accordingly.
The obvious problem here is that a user can plug in any number to that URL and edit someone else's page.
One obvious fix would be to add logic that checks whether or not page '1' belongs to the Auth::user(). But this would be an if statement that I have to add to every controller that carries out such function.
When I think about other sites, they never have ID's in the URL, or if they do, they look 'encrypted' in some form. What is the best practice for changing an ID into some uninterpretable string that I frequently see done on other websites?
Thank you for any help.
why don't you just use a middleware that check if the route can be acceded by the user? then you can call it with
$this->middleware('middlewareName');
in the controller that you need it or even in the web.php if you want a whole set of routes protected
I have developed one dashboard application in angular js which is having search functionality and multiple views with lots of different data coming from that search functionality.
Its single page application. So I am facing issue on page reload all data is gone and it shows view with blank data.
Is there any way to solve this issue or any language which help me to create single page application and maintain same data on page reload??
Any suggestion will be appreciated.

You can use sessionStorage to set & get the data.
Step 1 :
Create a factory service that will save and return the saved session data based on the key.
app.factory('storageService', ['$rootScope', function($rootScope) {
return {
get: function(key) {
return sessionStorage.getItem(key);
},
save: function(key, data) {
sessionStorage.setItem(key, data);
}
};
}]);
Step 2 :
Inject the storageService dependency in the controller to set and get the data from the session storage.
app.controller('myCtrl',['storageService',function(storageService) {
// Save session data to storageService on successfull response from $http service.
storageService.save('key', 'value');
// Get saved session data from storageService on page reload
var sessionData = storageService.get('key');
});
You need to save data before changing the state of application / moving to another page,route.
So, either save that data using
Angular services (Save data, change route, come back check the data in service and reassign variables from service.)
Local-storage to save data. (Save data, change route, come back check the data in service and reassign variables from service.)
Rootscope. Set data in rootscope and move .. after coming back check the variables and reassign.
Your problem is not saving the data, but saving the state in your URL. As it is, you only save the "step", but no other information, so when you reload the page (refresh, or close/re-open browser, or open bookmark, or share...) you don't have all the information needed to restore the full page.
Add the relevant bits to the URL (as you have a single page app, probably in the fragment identifier). Use that information to load the data, rather than relying on other mechanisms to pass data between the "pages".
Get data on page refresh, that is something like,
$rootScope.on('onStateChangeStart', function(){
// here make a call to the source
$http(); // request and try to get data
})
use localStorage or save data to your server for users in a database temporarily and get it back with an API call(localstorage has a 10MB) limit.
You can have your code try to retrieve localstorage values first if they exist.
I have a custom URL route for a controller action i.e:
['pattern'=>'<username>/<post_slug>', 'route'=>'post/view'],
Entering something like localhost/thisismyname/my-user-post would call post/view with the username and post_slug parameters as intended.
The issue with this route is that all my other controller actions no longer work. localhost/post/index would call post/view with the parameters post as username and index as post_slug.
Is there an efficient way to give priority to <controller>/</action> URLs, and if there's no said <controller>/<action> it would pass the parameters as <username>/<post_slug> to the post/view URL route?
I don't want to create a separate route like site/<controller>/<action> or manually add every controller & action as a route into the URL Manager since both are ugly workarounds.
The rule that you specify is very ambigous, so almost any route match it.
You can write a urlRule class and check, is the route <username>/<post_slug> route or not.
As another solution you can place this rule at the very end of your urlManager's rules configuration array.
Before I used Codeigniter I had a page show certain html as long as the url had no get parameters and then have some of the html be replaced by another as soon as something like this is set in the url:
localhost/signup.php?success
Now my question is, what is the best way to do this in Codeigniter? Would I have to use one of those parameters on the controller's function (which I still can't get my head around)? And if so, how? Or if I just had php logic in the view like I used to do in plain PHP, what would I check for if not a get parameter? Thanks.
Too many ways to achieve this certain thing.
routes.php
extending controller and using constructor so you apply rules for every extended controller
flashdata
Before you start please read up on frameworks watch some video tutorials on how to make simple blog system etc. I myself wouldn't just jump in to concept, study up.
I mentioned flashdata and that is how you do things done (success, alert, warning bars).
By default, GET parameters are not enabled or useful in codeigniter, but URI segments work the same way. So...
If you had a controller called, signup.php and a function inside it called success, you could link to that with:
localhost/signup/success
then if you loaded the URL helper, which I always do in config/autoload.php or just with:
$this->load->helper('url');
You could say:
if($this->uri->segment(2) == 'success') {
//Show success message or load a view for it...
}else {
//The second URI segment is NOT 'success' so do something else...
}
But... codeigniter is just a framework for PHP. If it's possible in PHP, it's possible in codeigniter. You can simply go into the config/config.php file and enable query strings, but I would strongly suggest using URI segments and reading up on them as well as the URL helper.
