php - $_POST empty when using $.post -


here problem: want make database search using php form. have form , want work if there empty fields (as more fields u fill, more specific answer u get). using jquery first values form , send $.post actual php file connects database , search. giving empty fields specific value recognized in php file 'empty' field can make proper sql query. problem find $_post variables empty, though variables in jquesry script set properly. using method in other cases , works fine. have no idea if matter loading form inside main div using jquery well. alert(data) function job: in prompt window can see results of search reloading profile.php gives me nothing. here code:

form:

<script type="text/javascript" src="scripts/admin.js"></script> <form id="form_admin">     <table cellpadding="0" cellspacing="0" width="180">         <p style="line-height: 2cm; ">             <tr>                 <td width="50" class="label1">imię:</td>                 <td>                     <input id="imie" type="text" value="">                 </td>             </tr>             <tr>                 <td width="50" class="label1">nazwisko:</td>                 <td>                     <input id="nazwisko" type="text" value="">                 </td>             </tr>             <tr>                 <td width="50" class="label1">numer telefonu:</td>                 <td>                     <input id="telefon" type="text" value="">                 </td>             </tr>             <tr>                 <td align="center" colspan="2">                     <input type="button" id="register" value="pokaż!">                     <br>                 </td>             </tr>         </p>     </table> </form>

admin.js

$(document).ready(function () {     $("#register").click(function () {         if ($("#imie").val() != "") {             var imie = $("#imie").val();         } else {             var imie = 'nic';         }         if ($("#nazwisko").val() != "") {             var nazwisko = $("#nazwisko").val();         } else {             var nazwisko = 'nic';         }         if ($("#telefon").val() != "") {             var telefon = $("#telefon").val();         } else {             var telefon = 'nic';         }         $.post("profile.php", {             name: imie,             surname: nazwisko,             telephone: telefon         }, function (data) {             alert(data);         });         $("#main").load('profile.php');     }); });

profile.php

<? php include('config.php');#logging database if (isset($_post['name']) && isset($_post['surname']) && isset($_post['telephone'])) {     $imie = $_post['name'];     $nazwisko = $_post['surname'];     $telefon = $_post['telephone'];#then sql queries go...     while ($user = mysql_fetch_assoc($select)) {         echo 'order_id zamówienia: '.$user['orderinfo_id'];         echo 'data zamówienia: '.$user['date_placed'];     }     while ($user = mysql_fetch_assoc($select2)) {         echo 'suborder_id: '.$user['subitem_id'];         echo 'ilość: '.$user['quantity'];         echo 'koszt zamówienia: '.$user['cost'];     } } else {     echo "$_post variables aren't set"; } ?>

edit: have installed firebug , checked post profile.php after submitted data , contains variables expected.

try changing $.post function to:

$.post("profile.php", {         data: "&name=" + imie + "&surname=" + nazwisko + "&telephone=" + telefon     }, function (data) {         alert(data);     });
