Laravel 错误：View::__toString() 不得抛出异常

Question

I have a problem to loop GET data from URL. My array looks like after var dump:

array(5) {
[0]=>
array(5) {
  ["sku"]=>
  string(9) "AH1172164"
  ["name"]=>
  string(21) "dasdas"
  ["url"]=>
  string(42) "21321312"
  ["price"]=>
  string(6) "866.00"
  ["stocks"]=>
  array(1) {
    [0]=>
    array(3) {
      ["partner"]=>
      string(6) "321312"
      ["qty"]=>
      string(1) "1"
      ["spotted"]=>
      string(14) "1 month "
    }
  }
}

My code for looping the data in blade file:

@php 
    $d=$_GET['Api'];
    var_dump($d);

    foreach($d as $value)
    {
        echo $value;
    
    }
@endphp

When I use var_dump the data are listed correctly but when I want to loop the variable $d I got this error:

Method Illuminate\View\View::__toString() must not throw an exception, caught Facade\Ignition\Exceptions\ViewException: Array to string conversion (View: F:\xampp\htdocs\semafor-master\resources\views\platform\tools\

I have API.. and my controller for this:

public function gen(Request $request)
{
    // Some queries, and loops to fill $data variable..
    return \Redirect::route('platform.tools.gen', ['Api'=>$data]);
    
}

I can't use return view, I must use return redirect because after API REQUEST I want to redirect to this route. The gen view is Orchid admin panel screen. What can be the problem?

Thanks in advance.

Answer 1

Part of the answer is that somewhere in the stack, there's a call to a magic __toString() method. Exceptions being called therein is only allowable in Php 7.4 and up. Try wrapping your behavior in a generic try/catch and make it dump the message from the Exception that it's trying to throw. The message you're seeing now is just a symptom of a different problem.

Looks like you have an array of array variable, so you should encode your value to a string before printing it:

@php 
    $d=$_GET['Api'];

    foreach($d as $value)
    {
        echo json_encode($value);
    
    }
@endphp
