Plain meaning

Route Parameters is a Laravel Basics pattern for one practical job. Learn the input, apply the smallest working syntax, check the output, then reuse the pattern in a real feature.

Why it matters

Route Parameters matters because real Laravel Basics work needs consistent ways to retrieve records with relations. Without this pattern, the feature becomes harder to change, test and review.

Real use

In a real project, route parameters helps build a Laravel business administration screen using orders, customers and tracking numbers.

Working example

Core pattern

This is the version to read first, run next, and modify last.

use App\Http\Controllers\OrderController;
Route::get('/orders/{id}', [OrderController::class, 'show'])->middleware('auth');

Expected output

Laravel Eloquent fetches requested rows and blade renders dynamic SaaS panels.

Line by line

What each part does

Line 1 sets up the Route Parameters example: use App\Http\Controllers\OrderController;.

Line 2 adds one required part of the working pattern: Route::get('/orders/{id}', [OrderController::class, 'show'])->middleware('auth');.

Methods and commands

Route Parameters reference

Use these methods, commands, tags or properties with the working example above.

Route::get()

Route::get('/path', [Controller::class, 'method']);

Define a Laravel route mapping.

Route::get('/orders', [OrderController::class, 'index']);

belongsTo()

return $this->belongsTo(Parent::class);

Mini task

Build a tiny a Laravel business administration screen step that uses Route Parameters, then write the expected output before running it.

Checklist

Use it correctly
