Passing several items to the callback of each() function

@omar590

https://laravel.com/docs/8.x/collections#the-enumerable-contract

$collection = collect(['taylor', 'abigail', null])->map(function ($name) {
    return strtoupper($name);
})	

Every item will be strtoupper(...)

thanks for replying

but I want every 10 items, not just one

I want for the first 10 items for instance to take number 1, and the next 10 items to take number 2

@omar590

Ok, I did not understand that "... over each 10 of them".

Will this work? Use $key to work out your logic

$multiplied = $collection->map(function ($item, $key) {
    if ($key / 10)
    {
        return $item * 2;
    }
});

I will tell you the exact problem, you probably even have a better logic for it!

it's my first use to factories

and I have two tables, sections table that in one-to-many relation with users table

so how to create new users and assign each ten of them to an existing section

@omar590 show your factory code please, why not use a seeder?

I'm still figuring out how to write it :'D

so it's basically the default

$factory->define(User::class, function (Faker $faker){

return [

    'name' => $faker->firstName.' '.$faker->lastName,
    'email' => $faker->unique()->safeEmail,
    'email_verified_at' => now(),
    'password' => 'yIXUNpkjO0rOQ5byMi.Ye4oKoEa3Ro9llC/.og/at2.uheWG/igi', // password
    'remember_token' => Str::random(10),



];

});

I could elaborate more about the problem if you need any

and I'm sorry for being a novice

@omar590

Where is the section field?

@omar590

Use a seeder like here https://laravel.com/docs/8.x/seeding

Much easier to control your values.

    public function run()
    {
        for($i = 0; $i < 50; $++)
        {
            DB::table('users')->insert([
                'name' => Str::random(10),
                'email' => Str::random(10).'@gmail.com',
                'password' => Hash::make('password'),
                'section' => $i / 10;
            ]);
        }
    }
