PHP & jQuery "$.post" are making troubles. I'm posting a few variables to a PHP-File.

The jQuery is:

navigator.geolocation.getCurrentPosition(saveGeoLocation);
function saveGeoLocation(position) {
   var latitude = position.coords.latitude;
   var longitude = position.coords.longitude;   

   $.post("__g.php", { 
      latitude: latitude, 
      longitude: longitude 
   }).done(function(data) {
      console.log("Data Loaded: " + data);
   });

}

The PHP is:

$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "Position output: " . $latitude . $longitude;

The console is showing the echo correctly with all the information sent via jQuery. However on the page itself, the PHP-echo is just echoing the content inside the quotation marks but not the variables content.

The PHP is in a single file but imported to a bigger file via include().

(This is a reduced example, there could be a typo.)

Thanks for your wisdom!

----------EDIT--------:

My problem might be based on a rookie mistake. Is it possible to include a php file AND at the same time send data to it so that it outputs the data in the place you want it to? Like:

<somehtml>
<somejquery> *--> is retrieving Geolocation-coordinates and posting long/lat to "__g.php"*

<?php
    <somephp>
    include("__g.php"); *--> is echoing the full API-url containing the long/lat values from the jQuery-post*
    <someforeach> *--> for the received API-json*
?>
  • check in XHR under network tab of console, is it sending data or not – Ahmed Sunny Sep 11 '18 at 13:50

  • what exactly are you trying to achieve here? – 95faf8e76605e973 Sep 11 '18 at 13:57
  • click on it and scroll to end, see if data is there, lattitude and longitude, under form data – Ahmed Sunny Sep 11 '18 at 13:58
  • @AhmedSunny, yes form data is there. https://imghost.eu/2Zz/Bildschirmfoto_2018-09-11_um_16.05.37.png –  Sep 11 '18 at 14:06
  • @95faf8e76605e973, the long/lat data is being sent to an API and retrieving some information about the corresponding location. –  Sep 11 '18 at 14:07

    @ToE ok but you stated _However on the page itself, the PHP-echo is just echoing the content inside the quotation marks but not the variables content._ are you are trying to directly run the page with the php script? – 95faf8e76605e973 Sep 11 '18 at 14:14

    This seems to come up all the time on StackOverflow. You cannot just navigate to the PHP page; that will be a `GET` request and it won't have any `$_POST` parameters – Phil Sep 11 '18 at 14:38

    i don't think you need ajax for what your are ultimately trying to achieve. a simple form should do the trick. ajax is used so that you can display the data on the page that made the ajax request – 95faf8e76605e973 Sep 11 '18 at 15:12
  • But unfortunately the geodata only retrievable through Javascript. And I need to pass that location to some php so that the php is able to output the foreach for each parameter based on the output of an API-url. –  Sep 11 '18 at 15:18

change the following from:

   $.post("__g.php", { 
  latitude: latitude, 
  longitude: longitude 
  }).done(function(data) {
     console.log("Data Loaded: " + data);
  });

to 

   $.ajax({
       url: "__g.php",
       type: "POST",
       dataType "text",
       data: {
          latitude: latitude, 
          longitude: longitude
       },
       success: function(data) {
         console.log("Data Loaded: " + data);
       },
       error: function(data) {
          console.log("Error: an error occurred somewhere");
       } 
  });

change your php code from:

$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "Position output: " . $latitude . $longitude;

to

if (isset($_REQUEST['latitude']) && isset($_REQUEST['longitude'])) {
   $latitude = $_REQUEST['latitude'];
   $longitude = $_REQUEST['longitude'];

   print "Position output: " . $latitude . $longitude;
} else {
    header('HTTP/1.1 500 Internal Server');
    header('Content-Type: application/json; charset=UTF-8');
}
