404 error on route that exists in Laravel 8

Question

I get a 404 error when I access this edit_product route that is served by a Product controller, codes are attached below Route::get('/edit_product{id}', 'ProductController@editproduct'); I would like your help in finding where the error in my code is. Thank you.

Here is the relevant code:

web.php

<?php

use IlluminateSupportFacadesRoute;

Route::get('/', 'ClientController@home');
Route::get('/checkout', 'ClientController@checkout');

Route::get('/shop', 'ClientController@shop');
Route::get('/cart', 'ClientController@cart');
Route::get('/login', 'ClientController@login');
Route::get('/signup', 'ClientController@signup');

Route::get('/dashboard', 'AdminController@dashboard');


Route::get('/addcategories', 'CategoryController@addcategories');
Route::post('/savecategories', 'CategoryController@savecategories');
Route::get('/categories', 'CategoryController@categories');
Route::get('/edit_category{id}', 'CategoryController@edit');
Route::get('/delete{id}', 'CategoryController@delete');


Route::get('/addslider', 'SliderController@addslider');
Route::get('/sliders', 'SliderController@slider');

Route::get('/addproducts', 'ProductController@addproducts');
Route::get('/products', 'ProductController@products');
Route::post('/saveproducts', 'ProductController@saveproduct');
Route::get('/edit_product{id}', 'ProductController@editproduct');

Route::get('/orders', 'ProductController@orders');

            return redirect('/addproducts')->with('status1', 'You need to select a Category for your product');

        }

        }
    }
 

I have tried.

1. replacing it with full namespace: Route::get('/edit_product{id}', 'AppHttpControllersProductController@editproduct');
2. php artisan cache:clear
3. php artisan cache:cache

Answer 1

Change your route to:

Route::get('/edit_product/{id}', 'ProductController@editproduct')

and also your delete and edit_category route:

Route::get('/delete/{id}', 'CategoryController@delete');

Route::get('/edit_category/{id}', 'CategoryController@edit');
