jquery - Unable to pass data to php using ajax -

-

first echo images set id php function. im tyring id value jquery click function , pass php function, unfortunately undefined index error. can reason in xampp config or else? becasuse code seems "right".

jquery

$(function postimgid() {     $('img').click(function() {         var imgid = $(this).attr('id');         $.post('functions.php', {postid:imgid},             function(data) {                 $('#content').html(data);                 console.log(imgid);             });         });      });

php

function showplayer() {     $number ='';         $number = $_post['postid'];      if(isset($_post['postid'])) {         echo "<h2>";         echo $_post['postid'];         echo "</h2>";     } }

try:

put in click function:

   var imgid = $(this).attr('id');     $.ajax({         type: "get",         url: "functions.php",         data: 'playerid=' + imgid,         success: function(data){             $('#content').html(data);         }     });

now check isset($_get['playerid']) , on in php:

    if(isset($_get['playerid'])) {         echo "<h2>";         echo $_get['playerid'];         echo "</h2>";     }

this playerid should not important in database unique ai id.

whole thing works post see: http://api.jquery.com/jquery.post/
