jsonp

Hi Dongsan,

please use the following function to extract the JSONP resultset with PHP:

function jsonp_decode($jsonp, $assoc = false) {
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') {
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}

usage:
$data = jsonp_decode($jsonp);

best,

Robert

Thank you Robert for the reply. The thing is, I’ve already found that code in google and tried. Printing $data (echo $data;) yields null, and nothing is printed by $data->id. Really at a loss what I have done wrong…

the result is an array, so it can be displayed by print_r($data) respectively accessed by echo $data[‘identifer’]

Thank you and sorry for bugging you with this simple problem, but I’m not a programmer nor in a tech-side. Please understand.

I tried again with the codes you provided, but still no fruits.

print_r($data) prints nothing, and echo $data[‘id’] prints nothing, either.

Giving it a second glance, I guess this is because the response I get from the query is a bit different from what is described in https://www.mapsmarker.com/docs/api-tutorials/web-api/#response.

Under https://www.mapsmarker.com/docs/api-tutorials/web-api/#response, it is described that the response is as below;

jsonp(
  {
    success: true,
    searchkey: "markername",
    ....
    - data: [
      - {
          id: "1",
          markername: "test2",
          ....
        },
     + { ... },
     ....
   ]
  }
)

However, the response I actually get is as below;

Array
(
    [headers] => Array
        (
            [date] => Mon, 28 Apr 2014 11:41:09 GMT
            [server] => Apache
	    .......
            [content-type] => application/json; charset=utf-8
        )

    [body] => jsonp({
	"success":true,
	"searchkey":"markername",
	"searchvalue":"dongsan",
	"searchresults":1,
	"message":"Search completed - showing 1 results below",
	"data": [
		{"id":"68",
		"markername":"dongsan",
		.......
		}]});
    [response] => Array
        (
            [code] => 200
            [message] => OK
        )

    [cookies] => Array
        (
            [0] => WP_Http_Cookie Object
                (
                    [name] => qtrans_cookie_test
                    [value] => qTranslate Cookie Test
                    [expires] =>
                    [path] => /wordpress/
                    [domain] => 127.0.0.1
                )

        )

    [filename] =>
)

So, I get not only jsonp({...}) but also get

Array(
[headers]=>Array()
[body]=>jsonp()
[response]=>Array()
[cookies]=>Array()
[filename]=>
)

Could this be the reason of the problem?

Not sure how I did it, and why it is working, but I managed to get it working. The biggest fault I made was that I used wp_remote_post() to retrieve the result set. I changed the codes as below, and now it’s working. Just in case there are other silly beginners like myself, here’s the code I have:

function jsonp_decode($jsonp, $assoc = false) {
if($jsonp[0] !== '[' && $jsonp[0] !== '{') {
   $jsonp = substr($jsonp, strpos($jsonp, '('));
}
$jsonp = json_decode(trim($jsonp,'();'), $assoc);
$jsonp = $jsonp->data[0];
return $jsonp;
}

$jsonp = $response['body'];
$data = jsonp_decode( $jsonp );

echo "ID = ".$data->id;
echo "Markername = ".$data->markername;
echo "layer = ".$data->layer;

great to hear that you could solve this issue!
best,
Robert
