Live Update Table entries to database SQL PDO AJAX - php

Question

i try to make an editable-table on a homepage which automatically save the new entries after you leave the "field" or press enter but something doesnt work.
Everthing is fine until i want to save the new entrie to database.
I fired the PDO-SQL-Statment and it works.
For me it seems to be the table_edit_ajax.php wasnt work but i dont know why!
Hope some of you guys can help me?
Im using a normal mysql database
Homepagecode:
<Table>
$getIDBusinessRessources = $dbPDO->geteditableSingleBusinessRessoure();
foreach($getIDBusinessRessources as $getidBusiness){
$id = $getidBusiness['checkid'] ;
echo '<tr id="'
. $getidBusiness['checkid']
. '" '
. 'class="edit_tr"'
. '>';
// Spalte Ressourcenname
echo '<td class="edit_td">'
.'<span id="RessourceName_'
.$getidBusiness['checkid']
. '" '
. 'class="text">'
.$getidBusiness['Rn']
.'</span>'
.'<input type="text" value="'
.$getidBusiness['Rn']
. '" class="editbox" id="Ressourcname_Input_'
. $getidBusiness['checkid']
.'">'
.'</td>';
// Spalte Amount
echo '<td class="edit_td">'
.'<span id="Amount_'
.$getidBusiness['checkid']
. '" '
. 'class="text">'
.$getidBusiness['AM']
.'</span>'
.'<input type="text" value="'
.$getidBusiness['AM']
. '" class="editbox" id="Amount_Input_'
. $getidBusiness['checkid']
.'" '
.'</td>';
</tr>
</table>
JS:
$( document ).ready(function() {
$(".edit_tr").click(function()
{
var ID=$(this).attr('id');
$("#RessourceName_"+ID).hide();
$("#Amount_"+ID).hide();
$("#Ressourcname_Input_"+ID).show();
$("#Amount_Input_"+ID).show();
}).change(function()
{
var ID=$(this).attr('id');
var first=$("#Ressourcname_Input_"+ID).val();
var last=$("#Amount_Input_"+ID).val();
var dataString = 'id='+ ID +'&RessourceName='+first+'&Amount='+last;
$("#RessourceName_"+ID).html('<img src="img/bearbeiten.png" />'); // Loading image
if(first.length>0&& last.length>0)
{
$.ajax({
type: "POST",
url: "table_edit_ajax.php",
data: dataString,
cache: false,
success: function(html)
{
$("#RessourceName_"+ID).html(first);
$("#Amount_"+ID).html(last);
}
});
}
else
{
alert('Enter something.');
}
});
// Edit input box click action
$(".editbox").mouseup(function()
{
return false
});
// Outside click action
$(document).mouseup(function()
{
$(".editbox").hide();
$(".text").show();
});
Ajax Code:
<?php
include "DBconnection.php";
if($_POST['id']){
$id = $_POST['checkid'];
$RessourceName = $_POST['Rn'];
$Amount = $_POST['AM'];
$dbPDO->UpdateLiveTableEntries($id,$RessourceName, $Amount );
}
?>
and at least the DB-Update code
function UpdateLiveTableEntries($id ,$Ressourcename, $Amount ){
// echo '<script type="text/javascript"> alert("inside");</script>';
$stmt = self::$_db->prepare("UPDATE BalancesheetInput SET RessourceName =:ressname , Amount =:menge WHERE ID =:id");
$stmt->bindParam(":id", $id);
$stmt->bindParam(":ressname", $Ressourcename);
$stmt->bindParam(":menge", $Amount);
$stmt->execute();
}

If you're sending this:
var dataString = 'id='+ ID +'&RessourceName='+first+'&Amount='+last;
^^ ^^^^^^^^^^^^^ ^^^^^^
why are you looking for these?
$id = $_POST['checkid'];
^^^^^---you aren't sending a 'checkid'
$RessourceName = $_POST['Rn'];
^-- you aren't sending an 'Rn'
$Amount = $_POST['AM'];
^^-- you aren't sending an 'AM'
