"Your First App" - mysql not working

hi all,
i’m walking my first steps with dhtmlx and try to rebuild the “Your First App” (docs.dhtmlx.com/tutorials__firs … index.html).

I have XAMPP running on a Win7 maschine.

in Step 6 i’m supposed to connect to a mysql DB.

This is my contact.php

<?php
require("../codebase/connector/grid_connector.php");//adds the connector engine
$res=mysql_connect("localhost","root","");//connects to server with  db

mysql_select_db("mysql");//connects to db with name "dhtmlx_tutorial"  
 
$conn = new GridConnector($res);             //initializes the connector object
$conn->render_table("db","host","user,db");  //loads data //the method takes: the table's name, the id field, a list of fields to load

?>

and i’m receiving the following error:

googling gave me the suggestions, to exchange all mysql_* methods with mysqli_* methods, which carried the error a bit further:

do you have any idea?
I couldn’t find anything in the search facilities.

Thanks and Cheers,

Hi,

I am experiencing same issue. Did you find any solution to this problem?

Please, try to use PDO.
Something like this in your contact.php:

<?php require("../codebase/connector/grid_connector.php"); $res= new PDO("mysql:dbname=dhtmlx_tutorial;host=localhost","root",""); $conn = new GridConnector($res,"PDO"); $conn->render_table("contacts","contact_id","fname,lname,email"); ?>

You also need to update your dhtmlxConnector by the following link:
