Question

I am not sure what is happening with my code, My project is running smoothly under XAMPP Server, i am able to make connection between mysql and php, But when i moved this to another system, which has mysql community server, their the code is not working, i mean database is connecting, but not able to fetch data from the database.

Sample Code is as follows:

$host='localhost'; // Host name
$username='root'; // Mysql username
$password=''; // Mysql password
$db_name='test'; // Database name
$connect=@mysql_connect($host,$username,$password) or die("Cannot Connect to database");
@mysql_select_db($db_name,$connect) or die ("Cannot find database");

app Code:

 $sql="SELECT * FROM test.userdet WHERE emailId='$uName' and pwd='$pwd'";
 $result=mysql_query($sql);
 $count=mysql_num_rows($result);

according to $count i am redirecting it to other page.

I able to run it on other systems which has XAMPP itself, but its not running with mysql community server.

//Thanks to NullPointer, i got it by PDO, from now onwords i will continue with PDO for transactions.

Now i facing a new problem, i am calling a php_db script via ajax, after executing all PDO statements its not returning to ajax, Code snippet is below:

ajax call:-

  $.ajax({
      type: "POST",
      url: "common/dbPhpScripts/updateEvent.php",
      data: 'json=' + det,
      dataType: 'json',
      cache: false,
      success: function () {
          $('#cal').fullCalendar('refetchEvents');
          $('#edit_event').dialog('close');
      }
  });

sample php code after using PDO:

$stringData = $_POST['json'];
$mynewarray = json_decode($stringData, true);
$title=$mynewarray['title'];
$start= $mynewarray['start'];
$end= $mynewarray['end'];
$createDate=$mynewarray['createDate'];
$insertQuery=$db->exec("INSERT INTO calendar (User_Id, StartDateTime, EndDateTime, Event_Title, Create_Date) VALUES ('07','$start','$end','$title','$createDate')");

where i am going wrong?

Answer 1

its good to see what you getting in

success: function (data) {
   alert("data");
}

also you need to echo result in common/dbPhpScripts/updateEvent.php not redirect if you redirect you wont get result in ajax
