Gantt, Ajax Error

Hello,
I am using dhtmlxScheduler v.5.1.0 Professional
and i have an error when updating data from gantt
gantt_console

this is my js code :
gantt.init(“task_gantt”);
gantt.clearAll();
gantt.load(“gantt/gantt_task.php”);
var dp = new dataProcessor(“gantt/gantt_task.php”);
dp.init(gantt);

this is my php code:
include(‘connector/gantt_connector.php’);
include(‘connector/options_connector.php’);
require(“connector/db_postgre.php”);

$dbtype=“Postgre”;
$postrgre_connection = “host=hostname port=5433 dbname=bdname user=dbuser password=dbpassword”;
$res=pg_connect($postrgre_connection);

$gantt = new JSONGanttConnector($res, $dbtype);
$gantt->render_sql(“SELECT * FROM project”,“id_project”,“start_date,end_date,project_name,duration”);

Can you please help ?
Thanks.

Hello Christoph,
It is hard to suggest what might be wrong as I don’t see your code and don’t have enough information on how to reproduce the issue.
Please, send me your full PHP project or a new PHP project where I can reproduce the issue.

This is the complete code

Hello Christoph,
Thank you for sending me part of your code. But I couldn’t reproduce the issue as I don’t have all the scripts and functions you use. For example, I don’t have getXhr(); function.

I tried to add Gantt and Scheduler on the same page, and there is no error message when I update tasks and events:
http://snippet.dhtmlx.com/eba64f0d4

Please, send me your full archived project with all necessary javascript files. Or send me a full archived project with all necessary files where I can reproduce the issue locally.

Hello remi,
thanks a lot for you effort those are the files and this is to have a look

the update has no effect to the database and gives me in console the error i have posted.

app.js (2.7 KB)

Thanks.

This is the index.php

index.php (25.2 KB)

this is the db connection file

gantt_task.php (743 Bytes)

Hello Christoph,
Thank you for sending me the files and for giving me the link.
I was able to reproduce the issue. Looks like you have an old Gantt version(4.1). I tried Gantt 6.1.1, there is no such error.
And also, you need to define the Data Processor as gantt.dataProcessor():

var dp = new gantt.dataProcessor("gantt_task.php");

Thanks for assistance
there no error now but data still not saved in database.
Is there any way to get the values and update the database with a different function ?
or may be i missed something.

can you please check, Thnaks
you can see it with the same link, my code now look like this

gantt.init("task_gantt");
			gantt.clearAll();
			
			gantt.load("https://icoop.live/ic/gantt/gantt_task.php");
	
			var dp = new gantt.dataProcessor("https://icoop.live/ic/gantt/gantt_task.php");
			dp.init(gantt);
			
			dp.setTransactionMode("REST");
			
			// destroys data processor and detaches it from the gantt
			dp.destructor();

Hello Christoph,
I see that you still have the 4.1.0 version. However, it works correctly even with that version in my demo:
https://files.dhtmlx.com/30d/fa54a150108cb77875f49d73a8631228/d4i-demo.zip
But dp.destructor(); destroys the Data Processor so the changes won’t be sent after you use that command. Please, try to comment it and check how it works.

Hi Ramil
Thanks you for your response. You say it works for you, but when I want to save it does not work - no erro message saying it did not save, but upon refresh, nothing has changed:
How can it be that it “works” for you but on the same code, it does not work for me
Please kindly help urgently, we’re losing tons of time on this
Thank you

Hello Christoph,
Thank you for sending me your Gantt version. Please, do not post it publically.

Have you checked the demo I sent you? Here is the video that demonstrates how it works with the demo I sent you:
https://files.dhtmlx.com/30d/0d950a773e953cd93306116f824bca81/vokoscreen-2019-03-28_13-50-25.avi

I checked, that you commented this string:

dp.destructor();

So now it should work correctly.

I see that on your website the changes aren’t saved to the server. But at least, now Gantt sends those changes. You can open the web console on the network tab. Remove all messages and try moving any task. You will see the PUT request, it means that Gantt sends changes to the server:

So you need to check what might be wrong on the server side.
Please, add $gantt->enable_log("log.txt"); after the following string:

$gantt = new JSONGanttConnector($res, $dbtype);

but before this string:

$gantt->render_sql(“SELECT * FROM project”,“id_project”,“start_date,end_date,project_name,duration”);

After that, refresh the page, move any task and send me the contents of the log.txt file. If it is not created, you need to check that you have the permissions to write to that folder.
