    error "Your requirements could not be resolved to an installable set of packages." in laravel 8

    in Frameworks

    Posted

    Your requirements could not be resolved to an installable set of packages.

      Problem 1
        - Root composer.json requires php ^7.2 but your php version (8.1.0) does not satisfy that requirement.
      Problem 2
        - laravel/passport[v8.3.0, ..., 8.x-dev] require php ^7.2 -> your php version (8.1.0) does not satisfy that requirement.
        - Root composer.json requires laravel/passport ^8.3 -> satisfiable by laravel/passport[v8.3.0, ..., 8.x-dev].

    hi...

    I want when receiving information from the database , Make a change in one of the fields.

    I do not want to write the change function in the field on all models.

    I want to make changes to all the eloquent classes. (override methods).

     

    In all tables, I have a history field(created_at).

    I want to make the desired changes to this field when I receive the information

     

    No explanation in the Laravel Document about the Middleware

    Hi, in the kernel file, a number of arrays are defined... 

        protected $middleware = [
        // \App\Http\Middleware\TrustHosts::class,
        \App\Http\Middleware\TrustProxies::class,
        \Fruitcake\Cors\HandleCors::class,
        \App\Http\Middleware\PreventRequestsDuringMaintenance::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    ];

    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],


    protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'password.confirm' => \Illuminate\Auth\Middleware\RequirePassword::class,
        'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
    ];

     

    But Laravel's document does not explain them, what is the reason?

    Identify model class properties

    in Frameworks

    Posted · Edited by ali_254

    hi.

    I wrote this code and printed it: 

          $category=Category::find(16);
         dd($category);

     

    The result: (The result of executing the above code , return an object of the category class.) 

    App\Models\Category {#1353 ▼
  #connection: "mysql"
  #table: "categories"
  #primaryKey: "id"
  #keyType: "int"
  +incrementing: true
  #with: []
  #withCount: []
  +preventsLazyLoading: false
  #perPage: 15
  +exists: true
  +wasRecentlyCreated: false
  #escapeWhenCastingToString: false
  #attributes: array:5 [▶]
  #original: array:5 [▶]
  #changes: []
  #casts: []
  #classCastCache: []
  #attributeCastCache: []
  #dates: []
  #dateFormat: null
  #appends: []
  #dispatchesEvents: []
  #observables: []
  #relations: []
  #touches: []
  +timestamps: true
  #hidden: []
  #visible: []
  #fillable: array:2 [▶]
  #guarded: array:1 [▶]
}

     

     

    but , When I run this code: 

            $category=Category::find(16);
        $class_vars = get_object_vars($category);
        dd($class_vars);

     

     result: 

    array:5 [▼
  "incrementing" => true
  "preventsLazyLoading" => false
  "exists" => true
  "wasRecentlyCreated" => false
  "timestamps" => true
]

     

    Which of the results, Are the real properties of category class ?
      I'm confused

    elequent ,returns Model class or Collection class?

    First only returns a single item, so there's no point in putting it in a collection.

    The collection is for methods that might return several items. 

    thanks...

    collection class in laravel , Uses standard php functions? (Functions of working with arrays in php)

     Or does it use other "mechanisms"?

    hi...

    hello everybody...

    I create model and wrote this code in controller (my model name in Category):

      

          $category=Category::all();
        dd($category);

    When I use "all" method , This returns the result: 

    Illuminate\Database\Eloquent\Collection {#1024 ▼
  #items: array:3 [▶]
  #escapeWhenCastingToString: false
}

    In fact, it is the output of the Eloquent/collection class.

     

    But, when I use "first" method: 

       $category=Category::first();
        dd($category);

    Returns the Models\Category class: 

    App\Models\Category {#1022 ▶}

     

     

    According to Laravel documents:

    Quote

    As we have seen, Eloquent methods like all and get retrieve multiple records from the database. However, these methods don't return a plain PHP array. Instead, an instance of Illuminate\Database\Eloquent\Collection is returned.

    Our output must be from Eloquent/collection class ... But, when I use "first" method , Returns the Models\Category class.

     

    what is the reason?!!

    How to Create AJAX Pagination in CodeIgniter 4?

    in Frameworks

    I'm not too sure as I haven't done it yet, but the only difference would be when you go fetch the data that instead of directly getting from PHP that you would get it from AJAX/JSON.  That way the page doesn't reload and has a more seamless appearance to the user.

     

    I want to use the pagination in CodeIgniter 4. When I use Ajax, it is not possible to use pagination....
