Sending multiple parameters at Pipeline

[hasansoyalan]

Hello,

Since pipeline accept single parameters, i would like to propose adding multiple parameters to Pipeline->send().

app(Pipeline::class)
    ->send($content, $user)
    ->through(FixMissingUsersPipe::class)
    ->then(function ($content, $user) { // Sending Multiple parameters
        // save to database etc...
    });

And usage is :

class FixMissingUsers
{
    public function handle(Content $content, User $user, $next)
    {
        // fix user
        return $next($content, $user);
    }
}

Or you use a DTO. There is nothing wrong with using DTO's in this scenario. Could be as simple as a stdClass object

        return $next($content, $user);
    }
}

Try using it like:

class FixMissingUsers
{
    public function handle(Content $content, $next, ...$parameters)
    {
        // fix user
        return $next($content, $parameters);
    }
}

Here you will receive array of multiple arguments in $parameters variable.

Doesn't work. send does not allow you to add a second parameter.
It does however work for strings. So if he would pass FixMissingUsersPipe:1234 and then resolve the userId within the pipe.

Another solution would be passing it to the constructor

app(Pipeline::class)
    ->send($content)
    ->through(new FixMissingUsersPipe($user))
    ->then(function ($content) use ($user) { // Sending Multiple parameters
        // save to database etc...
    });

You can try using DTO or check this link 1 here you can create transport like UserRegistrationTransport or link 2 here you can create class with constructor like SubscribeProcedure.

Thanks for the answer.... ==>>>> #45302 (comment)

[henzeb]

you are binding it to the closure that is executed at the end, not during. and send still doesn't accept 2 parameters.

Ah, you're right 🤦🏻‍♂️

->through([
    new (QueryFilter::class)($q),
])

// Query filter class 

protected string $q;

public function __construct(
    $q
) {
    $this->q = $q;
}

this works and through this, you can pass any number of parameters.
