在laravel中重定向具有紧凑值

Question

Route :

Route::get('merchantTrans/{id}','MerchantController@merchant');

Merchant Controller :

public function merchant($id){
    $merchant = Merchant::whereId($id)->get();
    return redirect('Merchant view')->with(compact('merchant'));
}

View Route :

Route::view('Merchant view','merchant.listview')->name('Merchant view');

I cannot pass merchant compact value to view.

Produce error

Undefined variable: merchant

Any other best way?

Answer 1

Try this

return redirect()->route('Merchant view')->with( ['merchant' => $merchant] );

In blade file :

<?php $merchants = Session::get('merchant'); ?>
{{ @foreach ($merchants as $merchant)
    //your code
@endforeach }}

Hope it helps you !

The Route::view is made for the static views with static parameters passed like :

Route::view('Merchant view','merchant.listview', ['param1' => 'value1']);

Since you want to pass dynamic parameters then it will be better to use the regular route passing by the related controller action and retrieving the desired data.

Anyway you could use Redirect::route() like :

return Redirect::route('Merchant view',['merchant' => base64_encode($merchant)]);

And get the passed variable in the blade side as a HTTP parameter using :

{{ base64_decode(Request::get('merchant')) }}

You can pass value from controller to view by using compact the Exact syntax should be like this

$user_detail=array('field1'=>1,'field2'=>2);
return view('dashboard',compact('user_detail'));

The variable name(user_detail) should be same as the name in compact. Right syntax for laravel 5.4 and heigher versions.
