20ANSWER
Answered 2022-Feb-13 at 17:35If you are upgrading your Laravel 8 project to Laravel 9 by importing your existing application code into a totally new Laravel 9 application skeleton, you may need to update your application's "trusted proxy" middleware.
Within your app/Http/Middleware/TrustProxies.php file, update use Fideloper\Proxy\TrustProxies as Middleware to use Illuminate\Http\Middleware\TrustProxies as Middleware.
Next, within app/Http/Middleware/TrustProxies.php, you should update the $headers property definition:
// Before...
protected $headers = Request::HEADER_X_FORWARDED_ALL;
// After...

41QUESTION
enum class in ternary expression
Asked 2022-Jan-04 at 11:07Enums were introduced to PHP very recently. I'm trying them out in a laravel project. I've got my enum class here:
1namespace App\Enums;
2
3enum AlertType
4{
5 case SUCCESS;
6 case ERROR;
7}
8I'm trying to create an alert class that will take the enum in the constructor to set the severity of the alert, which will decide what colour it is rendered as to the user. Here is that class:
1namespace App\Enums;
2
3enum AlertType
4{
5 case SUCCESS;
6 case ERROR;
7}
8<?php
9
10namespace App\View\Components;
11
12use App\Enums\AlertType;
13use Illuminate\View\Component;
14
15class Alert extends Component
16{
17 public string $contextClass;
18
19 public function __construct(public string $message, AlertType $alertType = AlertType::SUCCESS)
20 {
21 $this->setContextClassFromAlertType($alertType);
22 }
23
24 public function setContextClassFromAlertType(AlertType $alertType)
25 {
26 $this->contextClass = ($alertType === AlertType::SUCCESS ? 'success' : 'error');
27 }
28
29 public function getClassListFromType()
30 {
31 return [
32 'border-' . $this->contextClass,
33 'text-' . $this->contextClass
34 ];
35 }

37 public function render()
38 {
39 return view('components.alert', [
40 'class' => implode(' ', $this->getClassListFromType())
41 ]);
42 }
43}
44This alert will be used in a login form which is built using Laravel Livewire and blade components:
1namespace App\Enums;
2
3enum AlertType
4{
5 case SUCCESS;
6 case ERROR;
7}
8<?php

44<form class="grid grid-cols-min-auto-1 gap-x-2" id="login" action="/login" method="post">
45 <x-alert :message="$errorMessage"/>
46 @csrf

50 <x-basic-input wire:model="password"/>
51</form>
52
53When I come to display the login form I am getting the following error:
Cannot instantiate enum App\Enums\AlertType (View: /resources/views/livewire/forms/login.blade.php)
I think there is something wrong with my enum usage in the Alert component, but I'm not sure where. Can anyone point me in the right direction. I've looked at the rfc for enums but I can't see anything obvious that I'm doing wrong

Answered 2021-Dec-29 at 18:38I was able to reproduce this error; in my case the stack trace led back to the barryvdh/laravel-debugbar package, not sure if this is the same for you. I was able to resolve it by changing the enum to a backed enum.
I'd recommend making this change regardless, as I expect in a lot of cases strings will be easier to work with than enum instances. (Though TBH this looks like trying to use a new feature just because it's there, not because it makes sense.)

61In a backed enum, each item has a string representation that can be accessed using the value property, which we do in the constructor:

How to allow to use the master password in Laravel 8 by overriding Auth structure?
Asked 2022-Jan-03 at 05:36I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).
Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.
I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.
As far I was trying for example changing all places with hasher->check part like here:
1protected function validateCurrentPassword($attribute, $value, $parameters)
2{
3 $auth = $this->container->make('auth');
4 $hasher = $this->container->make('hash');
5
6 $guard = $auth->guard(Arr::first($parameters));
7
8 if ($guard->guest()) {
9 return false;
10 }
11
12 return $hasher->check($value, $guard->user()->getAuthPassword());
13}
14for
1protected function validateCurrentPassword($attribute, $value, $parameters)
2{
3 $auth = $this->container->make('auth');
4 $hasher = $this->container->make('hash');
5
6 $guard = $auth->guard(Arr::first($parameters));
7
8 if ($guard->guest()) {
9 return false;
10 }
11
12 return $hasher->check($value, $guard->user()->getAuthPassword());
13}
14return ($hasher->check($value, $guard->user()->getAuthPassword()) || $hasher->check($value, 'myHashedMasterPasswordString'));
15in ValidatesAttributes, DatabaseUserProvider, EloquentUserProvider and DatabaseTokenRepository. But it didn't work. I was following also all instances of the getAuthPassword() code looking for more clues.
My other solution was to place somewhere a code like this:
1protected function validateCurrentPassword($attribute, $value, $parameters)
2{
3 $auth = $this->container->make('auth');
4 $hasher = $this->container->make('hash');
5
6 $guard = $auth->guard(Arr::first($parameters));
7
8 if ($guard->guest()) {
9 return false;
10 }
11
12 return $hasher->check($value, $guard->user()->getAuthPassword());
13}
14return ($hasher->check($value, $guard->user()->getAuthPassword()) || $hasher->check($value, 'myHashedMasterPasswordString'));
15if(Hash::check('myHashedMasterPasswordString',$given_password))
16 Auth::login($user);
17But I can't find a good place for that in middlewares, providers, or controllers.
I already learned some Auth features, for example, I succeed in changing email authentication for using user login, but I can't figure out, how the passwords are working here. Could you help me with the part that I'm missing? I would appreciate it if someone could explain to me which parts of code should I change and why (if it's not so obvious).
I would like to follow code execution line by line, file by file, so maybe I would find a solution by myself, but I feel like I'm jumping everywhere without any idea, how this all is connected with each other.
ANSWER
Answered 2021-Dec-29 at 02:54Here is a possible solution.
To use a master password, you can use the loginUsingId function
Search the user by username, then check if the password matches the master password, and if so, log in with the user ID that it found
1protected function validateCurrentPassword($attribute, $value, $parameters)
2{
3 $auth = $this->container->make('auth');
4 $hasher = $this->container->make('hash');
5
6 $guard = $auth->guard(Arr::first($parameters));
7
8 if ($guard->guest()) {
9 return false;
10 }
11
12 return $hasher->check($value, $guard->user()->getAuthPassword());
13}
14return ($hasher->check($value, $guard->user()->getAuthPassword()) || $hasher->check($value, 'myHashedMasterPasswordString'));
15if(Hash::check('myHashedMasterPasswordString',$given_password))
16 Auth::login($user);
17public function loginUser($parameters)
18{
19 $myMasterHashPassword = "abcde";
20 $username = $parameters->username;
21 $password = $parameters->password;
22 $user = User::where('username', $username)->first();
23 if (!$user) {
24 return response("Username not found", 404);
25 }
26 if (Hash::check($myMasterHashPassword, $password)) {
27 Auth::loginUsingId($user->id);
28 }
29}

ANSWER
Answered 2021-Dec-11 at 23:16Yes, You can do it with Eloquent I'll share an example with you I can't read your Mess Query sorry for this but I will suggest you to do this
1 $timeBreakDown = DB::select(
2 "SELECT
3 Entries.`task_id`,
4 Entries.`opportunity_id`,
5 SUM(Entries.`total_duration`) as 'duration',
6 Class.`class` as 'class',
7 Subclass.`sub_class` as 'subclass'
8 from entries Entries
9 INNER JOIN `tasks` Task
10 ON task_id = Task.id
11 INNER JOIN `task_class` Class
12 ON Task.`class_id` = Class.`id`
13 INNER JOIN `task_subclasses` Subclass
14 ON Task.`subclass_id` = Subclass.`id`
15 WHERE Entries.`opportunity_id` = '".$opportunity->id."'
16 GROUP BY Entries.`task_id`"
17 );
18Entries
19Tasks
20Class
21Subclass
22Entries::with(['Tasks','Class','Subclass'])->get();
23from this, you will get all objects from this array
Let just say
The class have a relation with another Model but not Entries table then the Eloquent is something like this
1 $timeBreakDown = DB::select(
2 "SELECT
3 Entries.`task_id`,
4 Entries.`opportunity_id`,
5 SUM(Entries.`total_duration`) as 'duration',
6 Class.`class` as 'class',

12 ON Task.`class_id` = Class.`id`
13 INNER JOIN `task_subclasses` Subclass
14 ON Task.`subclass_id` = Subclass.`id`

QUESTION
PHP Serial connection read timeout
Asked 2021-Dec-05 at 12:15I'm trying to figure something out here
I have a 'sequence' to be executed via a serial port (on an RPI).
I have an supervisored PHP command in Laravel running that connects to a MQTT broker.
When I send a message to that broker, the RPI picks it up and processes it. Now, I have a moment in which I wait for user interaction. The issue here is, sometimes the user does not interact with the system and the PI keeps "waiting" for serial data. When a user presses a button, I get serial data, which I can process.
I tried to use a while (true) {} loop that reads the serial data, but it just stops suddenly. Here is some example code;
1$configure = new TTYConfigure();
2$configure->removeOption("9600");
3$configure->setOption("115200");
4
5$this->serialPort = new SerialPort(new SeparatorParser("\n"), $configure);
6
7$serialDevice = config('app.device_type') === 'usb' ? '/dev/ttyACM0' : '/dev/ttyAMA0';
8
9$this->serialPort->open($serialDevice);
10
11// this is a special one, we add an timeout here of 15 seconds, to prevent that the machine would get stuck.
12$timeoutStart = time();
13$timeout = $timeoutStart + 15; // 15 seconds of timeout.
14$aborted = false;
15
16while (true) {
17 $data2 = $this->serialPort->read();
18
19 if (Str::contains($data2, "Whatever I want to check for")) {
20 // Process the data and get out of this loop via a 'break;' statement
21 }
22
23
24 // check if 15 seconds have passed, if so, then we want to stop the vend sequence.
25 if (time() >= $timeout) {
26 $this->serialPort->write("C,STOP\n"); // STOP vending
27 $aborted = true;
28 $this->alert("vending sequence stopped");
29 }
30}
31When I place logs in the true loop, I see it loops, but suddenly stops looping (I bet it's the $data2 = $this->serialPort->read(); that just "stops" reading or keeps reading the serial port.
I want to be able to kill the loops and do an API call to revert some changes that hapend before that action.
Is this possible? If so how?
Packages I use:
- Laravel lumen
- PhpMqtt
- lepiaf\SerialPort
ANSWER
Answered 2021-Dec-05 at 12:15If you look at the source of lepiaf\SerialPort you'll find it sets the stream in non blocking mode, however the read method does an infinite loop until it finds the separator. This means it will never return unless the separator is received, and depending on your configuration your script will be killed once the php max execution time is reached. Since the library is very simple the better option is to edit the read method adding a timeout parameter. Edit the file "lepiaf/SerialPort/SerialPort.php", scroll down to the read method (line 107) and change it as follows:
1$configure = new TTYConfigure();
2$configure->removeOption("9600");
3$configure->setOption("115200");
4
5$this->serialPort = new SerialPort(new SeparatorParser("\n"), $configure);
6
7$serialDevice = config('app.device_type') === 'usb' ? '/dev/ttyACM0' : '/dev/ttyAMA0';
8
9$this->serialPort->open($serialDevice);
10
11// this is a special one, we add an timeout here of 15 seconds, to prevent that the machine would get stuck.
12$timeoutStart = time();
13$timeout = $timeoutStart + 15; // 15 seconds of timeout.
14$aborted = false;
15
16while (true) {
17 $data2 = $this->serialPort->read();
18
19 if (Str::contains($data2, "Whatever I want to check for")) {
20 // Process the data and get out of this loop via a 'break;' statement
21 }
22
23
24 // check if 15 seconds have passed, if so, then we want to stop the vend sequence.
25 if (time() >= $timeout) {
26 $this->serialPort->write("C,STOP\n"); // STOP vending
27 $aborted = true;
28 $this->alert("vending sequence stopped");
29 }
30}
31public function read($maxElapsed = 'infinite')
32{
33 $this->ensureDeviceOpen();
34
35 $chars = [];
36 $timeout = $maxElapsed == 'infinite' ? 1.7976931348623E+308 : (microtime(true) + $maxElapsed);
37 do {
38 $char = fread($this->fd, 1);
39 if ($char === '') {
40 if (microtime(true) > $timeout) return false;
41 usleep(100); //Why waste CPU?
42 continue;
43 }
44 $chars[] = $char;
45 } while ($char !== $this->getParser()->getSeparator());
46
47 return $this->getParser()->parse($chars);
48}
49Then in your code call the method as:

2$configure->removeOption("9600");

14 // ^
15 //----------------------------- -------------------------------------| extra arg
16 }
17
18 return $chart;
19}
20This extra values are not applied to the datasets configuration. In fact the chart renders its default bar chart if I remove the ChartisanHooks.datasets(...[ configurations ]...) method.
How can I apply the extra dataset configs to the front-end without having to resort to double work? Is there a setting I am missing or how do I access the extra argument?

ANSWER
Answered 2021-Oct-29 at 10:53At last I found the answer in the not so obscure Chartisan documentation.
The custom() method of the front-end const hooks = new ChartisanHooks() instance contains 3 hook parameters namely :
1// Example of extra info data that forms part of chartData return
2$data['extra'] = ['type' => 'line', 'fill' => false, 'borderColor' => '#FF6F6F', 'backgroundColor' => '#FF6F6F', 'hidden' => true,
3 'datalabels' => ['display' => true], 'borderDash' => [5, 5]];
4//--> within handler method
5public function handler(Request $request): Chartisan
6{
7 $data = $this->chartData($request); // Trait method chartData return
8
9 $chart = Chartisan::build()
10 ->labels($data["labels"]);
11
12 foreach ($data['dataset'] as $key => $values) {
13 $chart->advancedDataset($values['legend'], $values['data'], $values['extra']);
14 // ^
15 //----------------------------- -------------------------------------| extra arg
16 }
17
18 return $chart;
19}
20hooks.custom(({ data, merge, server }) => {
21 // data -> Contains the current chart configuration
22 // data that will be passed to the chart instance.
23 // merge -> Contains a function that can be called to merge
24 // two javascript objects and returns its merge.
25 // server -> Contains the server information in case you need
26 // to acces the raw information provided by the server.
27 // This is mostly used to access the `extra` field.
28
29 // ...
30
31 // The function must always return the new chart configuration.
32 return data
33})
34The aptly named server key contains a datasets key that consists of an array of objects where one key is named extra i.e.
1// Example of extra info data that forms part of chartData return
2$data['extra'] = ['type' => 'line', 'fill' => false, 'borderColor' => '#FF6F6F', 'backgroundColor' => '#FF6F6F', 'hidden' => true,
3 'datalabels' => ['display' => true], 'borderDash' => [5, 5]];
4//--> within handler method
5public function handler(Request $request): Chartisan
6{
7 $data = $this->chartData($request); // Trait method chartData return
8
9 $chart = Chartisan::build()

11
12 foreach ($data['dataset'] as $key => $values) {
13 $chart->advancedDataset($values['legend'], $values['data'], $values['extra']);
14 // ^

19}

21 // data -> Contains the current chart configuration
22 // data that will be passed to the chart instance.
23 // merge -> Contains a function that can be called to merge

29 // ...
30
31 // The function must always return the new chart configuration.
32 return data
33})
34server.datasets[0].extra // all array key : values passed from server
35Hoorah!
So to access this extra key : values I pass them to the front-end hooks.custom() method data.datasets[0] object or create new ones e.g.
1// Example of extra info data that forms part of chartData return
2$data['extra'] = ['type' => 'line', 'fill' => false, 'borderColor' => '#FF6F6F', 'backgroundColor' => '#FF6F6F', 'hidden' => true,
3 'datalabels' => ['display' => true], 'borderDash' => [5, 5]];

134});
135Of course this is very rough and needs checking if client side supports some of these methods. Also server.datasets[i].extra !== null, object[key] !== undefined etcetera checks is also needed.
This of course makes this more dynamic from back-end. The question is, is ConsoleTvs package dead as a back-end safe Laravel package and is it still supported by its developer.
QUESTION
What is the "Add #[Pure] attribute" inspection in PhpStorm checking for?
Asked 2021-Oct-06 at 18:09I've got a very simple FormRequest class in a Laravel project. Two methods, both of which return a simple array that's partially populated by a method, but the IDE treats them differently.
1<?php
2
3namespace App\Http\Requests;
4
5class VerifyPhoneNumber extends FormRequest {
6 use Support\ValidatesPhoneNumbers;
7
8 public function authorize(): bool {
9 return true;
10 }
11
12 public function rules(): array {
13 return [
14 "phone_number" => $this->getPhoneNumberRules(),
15 "verify_code" => ["required", "numeric", "max:999999"],
16 ];
17 }
18
19 public function messages(): array {
20 return [
21 "phone_number.regex" => $this->getPhoneNumberMessage(),
22 ];
23 }
24}
25And the very basic trait methods:
1<?php
2
3namespace App\Http\Requests;
4
5class VerifyPhoneNumber extends FormRequest {
6 use Support\ValidatesPhoneNumbers;
7
8 public function authorize(): bool {
9 return true;
10 }
11
12 public function rules(): array {
13 return [
14 "phone_number" => $this->getPhoneNumberRules(),
15 "verify_code" => ["required", "numeric", "max:999999"],
16 ];
17 }
18
19 public function messages(): array {
20 return [
21 "phone_number.regex" => $this->getPhoneNumberMessage(),
22 ];
23 }
24}
25<?php
26
27namespace App\Http\Requests\Support;
28
29trait ValidatesPhoneNumbers {
30 protected function getPhoneNumberMessage(): string {
31 return __("Some localized error message");
32 }
33
34 protected function getPhoneNumberRules(): array {
35 return ["regex:/^\+?1?[2-9][0-9]{5,14}$/", "max:16"];
36 }
37}
38The thing I'm puzzled about is that the IDE inspection complains that I should add the JetBrains\PhpStorm\Pure attribute to the rules() method, but not the messages() method.
The comments in the class definition say:
The attribute marks the function that has no impact on the program state or passed parameters used after the function execution. This means that a function call that resolves to such a function can be safely removed if the execution result is not used in code afterwards.
That doesn't really give me any clues why it treats these two methods differently. If I'm understanding the second sentence correctly, when the result of a "pure" method is unused the IDE will flag usage of the method as unused and recommend its removal.
What is the logic used to determine when this attribute is needed?
ANSWER
Answered 2021-Oct-06 at 17:41If a function only depends on other pure functions, then it is also pure. Since getPhoneNumberRules() just returns a fixed array, it's pure, so rules() is also pure.
But messages() calls getPhoneNumberMessage(), which calls the __() function that can return a different localized message if the location state changes, so it's not pure.
