未定义的变量：transaction_id（查看：resources / views / view_all_transaction.blade.php）

Question

How can i define transaction_id or initialize transaction_id in my laravel code i am stuck .

this the code on AdminContoller.php

 public function provetransaction(Request $req, $transaction_id)
    {

        $transaction_id = transaction::find ($req->transaction_id);
        $provetransaction = \DB::table('transaction')->where('transaction_id', $transaction_id)->first();
        return view('provetransaction', compact('amount_paid', 'transaction_id'));
    }
    public function updateprove(Request $request, $transaction_id)
    {
        switch($request->get('approve'))
        {
            case 0:
                Post::postpone($transaction_id);
                break;
            case 1:
                Post::approve($transaction_id);
                break;
            case 2:
                Post::reject($transaction_id);
                break;
            case 3:
                Post::postpone($transaction_id);
                break;
            default:    
                break;

        }
        return redirect('view_all_transaction');
    }

Below is my web.php where i have defined my routes.i have updated i have removed id i have used transaction_id instead.

web.php
Route::get('/view_all_transaction', 'AdminController@view_all_transaction')->name('admin');
Route::post('/view_all_transaction/{transaction_id}', 'AdminController@provetransaction')->name('admin');
Route::post('/view_all_transaction', 'AdminController@updateprove')->name('admin');

this my view_all_transaction.blade.php where the action is being passed so where i am wrong.

<td><a href="{{ action('AdminController@provetransaction', $view_all_transaction->transaction_id) }}" class="btn btn-warning">Moderate</a></td>

Answer 1

The error is indicating that you used $id in your view code. In order to do so, you should compact a variable called "id" to your view.
