Hi guys...
i want to delete data from datagrid in mysql...i have also done update query using same datagrid...
but i m not able to delete data...
my code is
<script type="text/javascript">
$(document).ready(function () {
// prepare the data
var data = {};
var theme = 'classic';
var source =
{
datatype: "json",
datafields: [
{ name: 'name'},
{ name: 'id'}
],
id: 'id',
url: 'data_qualification.php',
updaterow: function (rowid, rowdata, commit) {
// synchronize with the server - send update command
var data = "update=true&name=" + rowdata.name;
data = data + "&id=" + rowdata.id;
$.ajax({
dataType: 'json',
url: 'data_qualification.php',
data: data,
success: function (data, status, xhr) {
// update command is executed.
commit(true);
},
////I think here is some problem
deleterow: function (rowid, commit) {
var data = "delete=true&id=" + rowdata.id;
$.ajax({
dataType: 'json',
url: 'data_qualification.php',
data: data,
success: function (data, status, xhr) {
commit(true);
}
})}
});
}
};
var dataAdapter = new $.jqx.dataAdapter(source);
// initialize jqxGrid
$("#jqxgrid").jqxGrid(
{
width: 280,
height: 350,
selectionmode: 'singlecell',
source: dataAdapter,
theme: theme,
editable: true,
columns: [
{ text: 'ID', editable: false, datafield: 'id', width: 100 },
{ text: ' Certificate Name', datafield: 'name', width: 180 }
]
});
});
// delete row.
$("#deleterowbutton").bind('click', function () {
var selectedrowindex = $("#jqxgrid").jqxGrid('getselectedrowindex');
var rowscount = $("#jqxgrid").jqxGrid('getdatainformation').rowscount;
if (selectedrowindex >= 0 && selectedrowindex < rowscount) {
var id = $("#jqxgrid").jqxGrid('getrowid', selectedrowindex);
var commit = $("#jqxgrid").jqxGrid('deleterow', id);
}
});
</script>
and my php code is
<?php
#Include the connect.php file
include('../Scripts/connection.php');
#Connect to the database
//connection String
$connect = mysql_connect($hostname, $username, $password)
or die('Could not connect: ' . mysql_error());
//Select The database
$bool = mysql_select_db($database, $connect);
if ($bool === False){
print "can't find $database";
}
// get data and store in a json array
$query = "SELECT * FROM tblcertificate";
if (isset($_GET['update']))
{
// UPDATE COMMAND
//$update_query = "UPDATE `tblcertificate` SET `name`='".mysql_real_escape_string($_GET['name'])."' WHERE `id`='".mysql_real_escape_string($_GET['id'])."'";
$update_query = "update tblcertificate set name = '".mysql_real_escape_string($_GET['name'])."' where id = '".mysql_real_escape_string($_GET['id'])."' ";
$result = mysql_query($update_query) or die("SQL Error 1: " . mysql_error());
echo $result;
}
if (isset($_GET['delete']))
{
// delete COMMAND
//$update_query = "UPDATE `tblcertificate` SET `name`='".mysql_real_escape_string($_GET['name'])."' WHERE `id`='".mysql_real_escape_string($_GET['id'])."'";
$delete_query = "delete from tblcertificate where id = '".mysql_real_escape_string($_GET['id'])."' ";
$result = mysql_query($delete_query) or die("SQL Error 1: " . mysql_error());
echo $result;
}
else
{
// SELECT COMMAND
$result = mysql_query($query) or die("SQL Error 1: " . mysql_error());
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$certificate[] = array(
'name' => $row['name'],
'id' => $row['id']
);
}
echo json_encode($certificate);
}
?>
Hoping for solution
