Gantt group info


#1

Hi

I edited this post and will make 2 separate posts for my issues. :frowning:

I am trying to load a gantt chart from a database. I am a beginner in PHP and DHTMLX. Sorry in advance if I am missing something.

My question is How can I get the grouping data from the database? Replacing the hard coded (bold below) gantt.serverList…

Thanks in advance for any help.

===================
gantt2.php file

<?php include ("../codebase/connector/db_mysqli.php"); include ("../codebase/connector/gantt_connector.php"); // Mysql $dbtype = "MySQLi"; $res=mysqli_connect("right", "user", "password","table_name"); $gantt = new JSONGanttConnector($res, $dbtype); $gantt->render_links("gantt_links", "id", "source,target, type"); $gantt->render_table("gantt_tasks", "id", "start_date,duration,text,end_date,parent,progress,sortorder,color,training_type,country,baseline,masl,lm_plan_startdate,lm_actual_startdate,actual_delivery_date,location,work_package_status,work_package_req_approval_date,delivered_status,status_notes",""); ?>
