Decode json data to array and access the array in PHP(Laravel)

Question

I am trying to submit my form input as json format. After decoding json data into an array I can't access array.

{
    "info": {
        "q_title": "hello",
        "q_description": "ddd",
        "q_visibility": "1",
        "start_date": "Thu, 05 Oct 2017 06:11:00 GMT"
    }
}

This is my json data. My Laravel controller is following:

public function store_quiz(Request $request)
    {
        $data = json_decode($request->getContent(), true);

        $input = $arrayName = array(
            'title' => $data["info"]["q_title"], 
        );

        CreateQuiz::create($input);

        $redirect = '/';
        return $redirect;
    }

Unfortunately $data["info"]["q_title"] returns NULL. How to access "q_tittle" of my json??

can you print_r()$request->getContent());.may be that is null — Vision Coderz, Oct 05 '17 at 06:42
what `$request->getContent()` returns. Is it JSON encoded string? Moreover are you sure your JSON encoded string always has the above attributes which you are trying to access ? — Yaman Jain, Oct 05 '17 at 06:52

just access your data after json_decode like this without a second argument.

$data->info->q_title

and by using the second argument as true, which will convert your object into an array.

$data = json_decode($request->getContents(),true) //then use
$data['info']['q_title']

and if you are not getting anything in $request->getContents() then the problem lies in the request that you are sending.

@Dhaval.he given true so When TRUE, returned objects will be converted into associative arrays.that may be the reason down voted – Vision Coderz Oct 05 '17 at 06:49
@DhavalPurohit take a look into documentation http://php.net/manual/en/function.json-decode.php (-; – Neodan Oct 05 '17 at 06:50
ok then the problem should lie in `$request->getContent()` @iCoders – Dhaval Purohit Oct 05 '17 at 06:51

Maybe $request->getContent() content is different from your example, because for me it works.

Try to check what you have in $request->getContent().

Example:

<?php
$source = '{
    "info": {
        "q_title": "hello",
        "q_description": "ddd",
        "q_visibility": "1",
        "start_date": "Thu, 05 Oct 2017 06:11:00 GMT"
    }
}';
$data = json_decode($source, true);
echo $data['info']['q_title'];

Yes. Actually problem lies in $request->getContent(). @Neodan – Md Omar Faruk Oct 05 '17 at 08:28

Solution:

My data was saved in var data in jQuery.

To post data I used

$.ajax({  .... data: {data: data} .... });

instead of

 $.ajax({  .... data: data .... });

So I got unexpected value from $request->getContent().

Here's a more Laravel style method of doing this:

public function store_quiz(Request $request)
{
    $input = $arrayName = array(
        'title' => $request->input('info.q_title'), 
    );

    CreateQuiz::create($input);

    $redirect = '/';
    return $redirect;
}

And ensure your javascript app sets the Content-Type header to application/json. Laravel will json_decode() it for you.
