Issues with passing a variable with jQuery to PHP -

-

i have following code:

<?php      $id = $_get['id'];  ?> <html>     <head>         <script src="//code.jquery.com/jquery-1.11.3.min.js"></script>     </head>     <body>     <script>     var id = $.urlparam('id');      var id = <?php echo $id; ?>;      $.post("api.php", { id: id });      $.ajax({                                             url: 'api.php',                               data: "",                               datatype: 'json',                             success: function(data)                 {         var path = data[0];                  alert(path);       }      });      </script>     </body> </html>

i have variable in url called id (for example http://www.url.com?id=1) , i'm trying send page called api.php have database query. i'm trying corresponding value of id (in case path) , return it. seems variable id not being passed api.php. have hardcoded id variable in api.php ($id = 1), query working fine , after i'm able value database, when in api.php put following:

<?php    if($_post) {      $id = $_post['id'];   }  ?>

then it's not working. i'm not sure if $.post() method not working or reason i'm not able value of id variable in php script.

can me solve out?

first of all, $.post() call has no callback, though post request made, there no code execute when it's successful.

your second, $.ajax() call not specify type parameter (or data call), , result use get. inside api.php file, you're checking $_post super-global, of course not contain value id, since you're using get, not post.

you should update $.ajax() call follows:

$.ajax({                                           url: 'api.php',                             data: { 'id': <?php echo $_get['id'] ?> },                             datatype: 'json',        type: 'post'                }).done(function(data) {       var path = data[0];              alert(path); });

(you don't need first $.post() call, think have confused usage of function).

also, you'll need output api.php in order access in js, example:

<?php if( isset($_post['id']) ) {     echo $_post['id']; } ?>
