return json on laravel

Question

Uncaught SyntaxError: Unexpected token < in JSON at position 0

I need to return json, send it throw $.get request and show it with .html funtion. I would prefer dom option, but i have a laravel framework on backend, and i'm still using blade. So i have something like:

                $response = [
                    'success'   => true,
                    'content'   => view('/collette/create_step_01', compact('prodotto', 'destinatario', 'input'))->render(),
                ];

and i return

return json_encode($response);

There is a better way for return json on laravel?

On js i have

    var qs = getQueryString();

if (typeof(step) === 'undefined') {
    initColletta(); //define step
}

$.get(url + 'collette/create/steps/' + step, qs, function(data) {
    var res = JSON.parse(data);

    if (res.success) {
        showModalBody(res.content);

        if (typeof(res.stop) !== 'undefined' && res.stop) {
            $('#step-next').attr('href', res.link).unbind('click');
        }
    }
});

Answer 1

To return Json in Laravel you should use

return response()->json(your_json_here);

And as far as the error is concerned that is likely due to the fact that you don't need to Parse the JSON as it is already a valid JSON object.

Answer 2

The reason it says Uncaught SyntaxError: Unexpected token < in JSON at position 0 is because there is actually an error from the response itself...

Which i will assume to be the first "<" in the view you are returning via json_encode();

I'll suggest you confirm what is being returned first... probably via var_dump() .

And of course, another way to return json via laravel like you asked is

return response()->json(json_array);
