Question

framework is here
http://luracast.com/products/restler/

i’m using restler as restful api for my work,
when i use backbone model save to a url, it sends and update my data as json by using ‘HTTP PUT’ request method, and i want to get a response from what i’ve putted…

if it’s a HTTP POST request method i can use

// to getting content from a POST
$post_data = json_decode(file_get_contents('php://input'), true);

to get my content, but cant get anything from HTTP PUT

// can't get anything from a PUT
function putpatients($id) {
    $post_data = file_get_contents('php://input');
    $post_data = json_decode($post_data, true);
    echo $post_data['name'];
}

the browser response blank

how do i return my data as json ???

Answer 1

As I commented on your question, php://input is a stream, if you read from it, it empties it.

I’ve never used Restler before but looking at the few examples provided in their download, it seems to indicate the submitted data is automatically passed as a parameter to your put handler..

In Restler’s crud example, the Author class has a put request like this:

function put($id=NULL, $request_data=NULL) {
    return $this->dp->update($id, $this->_validate($request_data));
}

so i’m guessing that restler has already read the php://input stream, and hence emptied it.

so, your put handler should maybe be more like in their example:

function putpatients($id, $request_data = NULL) {
    /* do something with the $request_data */
    var_dump($request_data);
}

Edit: There’s actually a previous SO question from @deceze that talks about why reading twice from php://input doesn’t work – for PUT requests – which explains why your code worked with a POST request. Either way, you should really use the facility provided by Restler rather than re-inventing the rest wheel.
