Separate URL for front-end and for back-end - yii2

I am new to Yii framework.
I have downloaded Yii2, and Yii2 Advanced Application.
I want to create 2 URLs for front and for admin panel.
Front-end URL: http://localhost/advanced
Back-end URL: http://localhost/advanced/admin
How can I do this?

After downloading the Yii2 advanced template archive. Install the advanced Yii2 using this link Yii2 advanced installation guide
Follow all the steps in "Preparing application" section of above url.
After following all steps you are ready to go. Now you can access frontend and backend i.e
For ex:
FRONTEND: http://localhost/advanced/forntend/web
BACKEND: http://localhost/advanced/backend/web
Create admin panel in yii2 backend. Please follow this url Backend Admin panel
I know i am late to answer but i want to help other guys which are new to Yii2. I hope my points will be helpful.

The url routing subject is quite broad. You should start by reading the detailled documentation http://www.yiiframework.com/doc-2.0/guide-runtime-routing.html
Basically, you register an urlManager component in the application config. In the following example, front and admin are 2 controllers with an index action.
new yii\web\Application([
...
'components' => [
'urlManager' => [
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false
'rules' => [
'advanced' => 'front/index'
'advanced/admin' => 'admin/index'
]
],
]
...
])

The advanced application template was never designed to do that because it is two separate applications that requires two separate domains (subdomain for 'admin' is fine).
What you want to use instead is yii2-app-practical-a which does exactly what you want. :)
You have the main application you can access by your main URL - http://localhost/advanced and a back-end you can access by the main URL with admin appended: http://localhost/advanced/admin.

How to manage logins in two yii2 applications which use same database

I have two backend applications which use same database. If a user logs into one application and navigate other application url in another tab it loads inner pages without login to that application. Is this possible to restrict that or is this expected functionality?
Application 1 - www.test.com/app1
Application 2 = www.test.com/app2
I have to set who can access one application and who can access second application. Is it possible to do so? Is it possible to do with RBAC? Currently we implement permission based table set and try to check permission when login and navigating pages whether pages have sufficient privileges to do so.
Thanks
You need to change the name for the session cookie that is generated, my guess is that you are experiencing this because the name for the session cookie in both the apps is the same, and you are using the same browser to verify the App2 when you login to APP1, which forces the browser to read the same cookie for the session and finds you are already logged in.
Change them in the configs for both the applications like below
Application 1
'session' => [
// this is the name of the session cookie used for login on the backend
'name' => 'app1-frontend',
'class' => 'yii\web\DbSession',
'cookieParams' => [
'httpOnly' => true,
],
],
Application 1
'session' => [
// this is the name of the session cookie used for login on the backend
'name' => 'app2-frontend',
'class' => 'yii\web\DbSession',
'cookieParams' => [
'httpOnly' => true,
],
],
if you want separate logins for the frontend and backend you can do the same for the frontend and backend configs too.

I want to get the backend url from frontend without using hardcoded URLs yii2

'urlManagerBackend' => [
'class' => 'yii\web\urlManager',
'baseUrl' => 'http://backend.test',
'enablePrettyUrl' => true,
'showScriptName' => true,
],
then I want to display the image saved under uploads directory
<img src="<?= Yii::$app->urlManagerBackend->baseUrl; ?>/uploads/logo.jpg>
the problem is this url must not be hardcode like this:
'baseUrl' => 'http://backend.test',
The only way how to dynamically determine the domain of the other application (for example the backend from your frontend) would be by parsing the web server's configuration files.
The domain for current application (the one you can get with Url::base(true)) is determined from the request headers or variables set by web server. But those are available only for current application, not for any other application even if they are part of same project.
If you want to parse web server's configuration files than you will have to face three major challenges:
Different web servers have different syntax for configuration files.
Configuration files might be located anywhere.
You might not have access rights to read the configuration files.
So it might be better to try to think about some workaround instead of insisting on determining the domain dynamically.
Make a deploy script that would ask for the backend domain. The one who will be deploying your application on production servers will know the domain for the backend application and can enter it during deployment process. The deploy script will then set the entered backend domain in your configuration files.
Make a page in backend that must be visited before accessing the frontend application. You can determine the domain for backend when the page in backend is visited then set that domain in frontend configuration files. If the frontend is accessed before the domain for backend is set you will only display the notice that the backend page must be accessed first.
In the config folder there should be a file called params.php. If you have something like this
<?php
return [
'adminEmail' => 'admin#example.com',
'baseUrl' => 'http://backend.test',
];
You can use it in your code like this
<img src="<?= Yii::$app->params['baseUrl']; ?>/uploads/logo.jpg>
Then when you move to live, you just need to edit the params.php file.
Too long comment so I need to put it here.
But I'm just wondering in which case that makes sense, except if you are creating web applications, sites, ..., through your application, which I doubt you do.
You know your local domain (use local environment and put urls).
You will know your dev domain (use dev environment and put urls).
You will know your production domain (use prod environment and put urls).
You can also have multiple applications inside yii2 project, so for example,
10 applications across 3 envs, that is 30 urls which you will enter in you configs.
Can you please tell me, how you will access your app if url is dynamically determined -> without using anything else except Yii?
What is your step? You are typing in your browser what? Then we can proceed. Maybe we misunderstand each other.
urlManagerBackend' => [
'class' => 'yii\web\urlManager',
'baseUrl' => 'http://backend.test',
'enablePrettyUrl' => true,
'showScriptName' => true,
]
If you are wondering you can also have multiple urlManagerBackend components across Yii2 environments. Just like with params. Add it on multiple corresponding places at config. So in specific environment you place at same file only key => values which you need to override.
You could simply use Assets and Aliases for this:
If you have a backup/web/uploads/ folder in which you save images uploaded via your backend and you'd like to display those images on your frontend.
Create a new asset file in your frontend/assets/, let's call it BackendAsset.php:
<?php
namespace frontend\assets;
use yii\web\AssetBundle;
class BackendAsset extends AssetBundle {
public $sourcePath = '#backend/web/uploads';
}
where $sourcePath is the backend-folder (source) you'd like to access on the frontend. The #backend alias is predefined in the advanced template, so we'll use it.
Now in our view we can simply use the BackendAsset:
<?php
use frontend\assets\BackendAsset;
$backend = BackendAsset::register($this);
?>
and now we can easily display a file, let's say backend/web/uploads/somefile.jpg:
<img src="<?= $backend->baseUrl . '/somefile.jpg' ?>" >
NOTE: Using the asset in this way copies all the files from the backend/web/uploads to an asset folder in the frontend. To prevent that, you can tell your application not to copy the files, but to link to them (creating SymLinks) instead, unsing linkAssets (yii2 docu):
In your app configuration (in this case frontend/config/main.php), set the linkAssets parameter to TRUE:
'components' => [
'assetManager' => [
'linkAssets' => true,
]
]
I solve this problem by saving the full url in the database.
What about putting a reverseproxy (e.g. nginx) in front of the frontend-server?
Could be configured like:
http://frontend/backend/* -> forwards everyhing to the backend service, the rest will still go to the frontend server.
The configuration (in this case the location of the backend server) of this reverseproxy can be changed any time (also after deployment).
Could that be a viable scenario?

Autodesk Forge API - Setting Scopes for data with read, write, and create

I initially created an app and starting developing it using only the data:read scope. I have now realized that I need the data:create scope as well.
Is there something within the app settings that I need to change?
Does the create scope include read permissions and then write scope include create and read - or does that scope have to be sent separately?
If separately, how is that done when the user is granting permission to the app? Is it something like &scope=data:read&scope:create
I don't have to store and then use two tokens, do I?
How is this handled when using curl? Are the read and create scopes sent in an array like so ...
$response = $client->request('POST', 'https://developer.api.autodesk.com/authentication/v1/gettoken', [
'form_params' => [
'grant_type' => 'authorization_code',
'code' => $authCode,
'client_id' => $FusionID,
'client_secret' => $FusionSecret,
'redirect_uri' => 'https://www.example.com/fusionauth',
'scope' => array('data'=>'create', 'data'=>'read')
]
]);
Again, it may be that you only use the scope you need and you have to store separate tokens, but that doesn't seem right to me.
Is there something within the app settings that I need to change?
If by app settings you meant in the Forge App portal then you only have to specify there the APIs (make sure they are checked on the page) that your app will need to access.
Does the create scope include read permissions and then write scope include create and read - or does that scope have to be sent separately?
No doesn't work like that - you will need to specify each one of them explicitly.
If separately, how is that done when the user is granting permission to the app? Is it something like &scope=data:read&scope:create
Nope the scope variables are delimited by space. For 3-legged oauth you will need to obtain an authorization code through redirecting the user to authenticate at our login portal before you go for access tokens and there you will need to indicate the redirection address and scope combinations in the request URL (don't forget to URLEncode them) such as https://developer.api.autodesk.com/authentication/v1/authorize?response_type=code&client_id=obQDn8P0GanGFQha4ngKKVWcxwyvFAGE&redirect_uri=http%3A%2F%2Fsampleapp.com%2Foauth%2Fcallback%3Ffoo%3Dbar&scope=data:read. See here for details.
And check out our official PHP client SDK - should save you tons of effort and time.
I don't have to store and then use two tokens, do I?
If your token carries sufficient permissions (say data:read and data:create) then no.
How is this handled when using curl? Are the read and create scopes sent in an array like so ...
For cURL see samples here: https://forge.autodesk.com/en/docs/oauth/v2/tutorials/get-2-legged-token/
And like we went through above you will need to specify the scopes when redirecting the user to authenticate so in your request to fetch the eventual access token you'd should something like:
$response = $client->request('POST', 'https://developer.api.autodesk.com/authentication/v1/gettoken', [
'form_params' => [
'grant_type' => 'authorization_code',
'code' => $authCode,
'client_id' => $FusionID,
'client_secret' => $FusionSecret,
'redirect_uri' => 'https://www.example.com/fusionauth'
)

Setting database parameters in Zend 3

I'm a serious newbie as it comes to Zend and I'm now forced to work with Zend 3 (and learn it). Fellow developers have done parts of the application and now I'm cloning it on my side.
I receive "Database not selected" in the error log - I have set database.local.php and I think they've set everything else. Credentials are correct.
I'm working on Windows.
Is there anything else I could be missing as it comes to settings or database connection?
Thanks. I will provide any additional info if needed.
As we're dealing with both Zend Framework AND a configuration issue, for your next question, please make sure to also include file paths and such.
I'm proceeding with this answer under the assumption that you've created your file here: /config/database.local.php.
Note: using ZF3 myself, I, of course, tried to find your error message "Database not selected", however it comes back with no results. Make sure you copy and paste error messages so users of any framework, cms or another system can more easily help you out.
You'll find the problem you're facing in the application.config.php file (in the /config folder. In here you'll find the following config:
// Retrieve list of modules used in this application.
'modules' => require __DIR__ . '/modules.config.php',
// These are various options for the listeners attached to the ModuleManager
'module_listener_options' => [
// ... other config
// An array of paths from which to glob configuration files after
// modules are loaded. These effectively override configuration
// provided by modules themselves. Paths may use GLOB_BRACE notation.
'config_glob_paths' => [
realpath(__DIR__) . '/autoload/{{,*.}global,{,*.}local,{,*.}deploy,{,*.}development}.php',
],
// ... other config
],
Any of the *.local.php or *.global.php config files should be placed in /config/autoload/. Though, if you modify the above config, you could technically place it wherever you'd like.
Next, make sure you have the Zend\Db module enabled in your configuration. Open up the /config/modules.config.php file and make sure Zend\Db is in the list of Zend modules to be loaded in.
Lastly, you have not provided the config you used, so I'm assuming you made a mistake there. Use something like the config below in your /config/autoload/database.local.php file. Technically you could split this over 2 files; a global and a local file. Local files are (/should) not be committed into version control history and as such can contain usernames and passwords. Any other config, such as using Pdo for a driver could go into global config.
'db' => [
'driver' => 'Pdo',
'dsn' => 'mysql:dbname=zf3;hostname=localhost',
'username' => 'root',
'password' => 'root',
'driver_options' => [
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
],
],

Yii2 overiding user/login for backend

I am using yii2-user module on top of the standard Yii2 advanced demo.
Yii2-user provides it's own login function at /user/security/login and linking directly to that works perfectly.
However the advanced demo overides that and directs the call to /user/login probably using the internal routes but I cant track down where that is happening.
I need to tell my Yii2 site not to chip in its own login ( which I have deleted ) and to retain the route to /user/security/login.
config file is directing user to the dektrium yii2-user module and it all seems to be working, it's just the default action into the backend page that reroutes to user/login when a visitor is a guest instead of a registered admin.
Backend has its own configuration, you should simply modify user component loginUrl in backend/config/main.php .
Inside your backend config.php add one more component
'user' => [
'loginUrl' => ['user/security/login'],
],
It helps me out in frontend
