jQuery post not passing parameters

Question

I have a problem with posting variable to php script and getting result back without refreshing page. php script koord.php is tested and it's working fine.

This is my js code (`adresa`, `mjest`o and `coords` are text input boxes):

$(document).ready(function () { $('#coord_click').click(function () { provjera(); }); }); function provjera() { var adresa = $('#adresa').val(); var mjesto = $('#mjesto').val(); var puna_adresa = adresa + " " + mjesto; $.post("koord.php", { puna_adresa: puna_adresa },function (result) { $('#coords').val(result); }); }

koord.php:

$puna_adresa = $_GET['puna_adresa']; function getCoordinates($address){ $address = str_replace(" ", "+", $address); $url = "maps.google.com/maps/api/geocode/…"; $response = file_get_contents($url); $json = json_decode($response,TRUE); return ($json['results'][0]['geometry']['location']['lat'].",".$json['results'][0]['geo‌metry']['location']['lng']); } echo getCoordinates($puna_adresa);

Complete source code is here: http://pastebin.com/u/bradetic

Thank you!

$puna_adresa=$_GET['puna_adresa']; function getCoordinates($address){ $address = str_replace(" ", "+", $address); $url = "maps.google.com/maps/api/geocode/…"; $response = file_get_contents($url); $json = json_decode($response,TRUE); return ($json['results'][0]['geometry']['location']['lat'].",".$json['results'][0]['geometry']['location']['lng']); } echo getCoordinates($puna_adresa); — user2986503

The Jquery POST is not the problem.

Your are doing $.post(...) which means that you need to get the parameter in koord.php via $_POST, and you are using $_GET, you see the problem right?

Solution

Change $_GET['puna_adresa']; to $_POST['puna_adresa'];

or

change $.post(...) for $.get(...) in your client side.

You know the difference between `POST` and `GET` right?

@user2986503: Don't forget to mark a response as the answer to the question. Good luck!

You seriously need to use Jquery AJAX, here's an example:

<script> function your_function() { // collect data like this var formData = jQuery("#your_form_id").serializeArray(); jQuery.ajax({ type: "POST", url:"your_php_page.php", data:formData, dataType:'json', beforeSend: function() { }, success: function(resp) { alert(resp); }, complete: function() { }, error: function(e) { alert('Error: ' + e); } }); } </script>

And you PHP script should go like this:

$puna_adresa=$_POST['puna_adresa']; function getCoordinates($address){ $address = str_replace(" ", "+", $address); $url = "maps.google.com/maps/api/geocode/…;; $response = file_get_contents($url); return $response; } $response = getCoordinates($puna_adresa); echo json_encode($response);

Can I use instead jQuery("#your_form_id") jquery("#adresa,#mjesto") because i have multiple input fields an I need just these two.
Is the same thing... there is no problem with the client side code
And instead alert(resp) can I put this $('#coords').val(resp) to show the results in input field? I haven't tried yet this because i'm at work now.
oops, my answer is perfect for this sort of problem but someone just vote down my answer, you are genius pal, i am still shocked :s
yes of coarse, your script will return you everything in resp array, you can easily put this array in a loop and alert it's contents.

Can you try this,

 $.post("koord.php", { puna_adresa: adresa, mjesto: mjesto }, function (result) { $('#coords').val(result); });

Another way:

 $.post("koord.php", $( "#testform" ).serialize(), function (result) { $('#coords').val(result); });
