PHP echo working with the browser, not with jQuery

I'm writing a web interface for an application. Since the elaboration time for the application can be pretty long, when it starts the user is shown a loading page and then an AJAX call loads the output to the page. If I browse the PHP function with my browser I get the correct response (a JSON), but when the AJAX call is executed jQuery gets an error 500 (I tried with the same parameters).

This is the JavaScript:

$.ajax({
      type: "GET",
      url: my_url,
      dataType: 'json',
      success: function(result){
          if (result.status == "COMPLETED") {
            window.alert("RETURNED");
            $("hocrDisplay").attr("src", result.html);
            $("hocrDownload").attr("href", resul.path);
            $("#loaderImage").hide();
            $("#hocrDisplay").show();
            $("#hocrDownload").show();
            window.alert("The file will be deleted in 10 minutes");
           }else{
             setTimeout(getStatus(requestid,filename), 3000);
          }
      },
      error: function (response) {
        alert("There was an error processing the document");
        $("#loaderImage").hide();

  }
  });

And this is the code around the PHP echo:

echo json_encode('{"status" : "COMPLETED", "html" : "' . $htmlname . '", "path" : "' . $tarpath . '"}');
ob_flush();
sleep(600);
unlink($tarpath);
unlink($htmlname);

This line is wrong:

echo json_encode('{"status" : "COMPLETED", "html" : "' . $htmlname . '", "path" : "' . $tarpath . '"}');

You should make an array and then encode it in JSON like this:

$array = array("status"=>"COMPLETED",
               "html"=>$htmlname,
               "path"=>$tarpath);
echo json_encode($array);

This encodes you the correct jSON. The 500 error is in server, so that line it that produces the error.

Good luck,

You are encoding the string which already encoded, its better to use an array than use json_encode function for encoding.

You can try like that:

// create an array for your values
$yourArr = array(
            'status'=>'COMPLETED',
            'html'=>$htmlname,
            'path'=>$tarpath);

// encode the array in json format
echo json_encode($yourArr);

json_encode will return this:

{"status":"COMPLETED","html":"test","path":"test2"}

Now, you can use it in ajax success as you are already doing.
