Hello,

I seem to have trouble using this library correctly. My goal is to use it as a JSON query tool on a directory of equal or different structured JSON files. Therefore I most likely do not have a huge json with a collection of data available.

Further I just want to get back a TRUE or the wohle object when my conditions are match. With my trys I get always the error message from the issue title.

Simple example from the readme.md:

$q = new Jsonq();
$q->collect(['id'=>1, 'name'=>'Nahid']);
$res = $q->where('name', '=', "Nahid")->get();

or

$q = new Jsonq('data.json'); // data from the README.md
$res = $q->where('name', '=', "products")->get();

When I try something else it returns empty even though I can see that it should match.

$q = new Jsonq();
$q->collect(['foo' => ['id'=>1, 'name'=>'Nahid']]);
$res = $q->where('foo.name', '=', "Nahid")->get();
// $res is empty array

Im having the same problem.

Any ideas on this one?

class C\A\MicroService
public function handle(string $json) : array
    {
        $jsonq = new Jsonq();
        $jsonq->json($json);

        $matchLevel = $jsonq->from('matchLevel')->get();

        if($matchLevel != 'Street number'){
            throw new \Exception('To low matchLevel, level is ' . $matchLevel );
        }

        $res = $jsonq->from('products')->get();
        return $res;
    }

EDIT:
Made a workaround that "works".

// class C\A\MicroService
public function handle(string $json) : array
{
        $jsonq = new Jsonq();
        $jsonq->json($json);

        // Repeated the object, clone does not work
        $jsonq2 = new Jsonq();
        // Run json method again. 
        $jsonq2->json($json);

        // Use the second json here
        $matchLevel = $jsonq2->from('matchLevel')->get();

        if($matchLevel != 'Street number'){
            throw new \Exception('To low matchLevel, level is ' . $matchLevel );
        }

        //Use the first json here
        $res = $jsonq->from('products')->get();
        return $res;
}
