DataProcessor error


I am using version 3.5 of the free suite. I have a dataview component connected to the db using dataprocessor. On the client side it goes like this:

[code] dataX0 = new dhtmlXDataView({
container: “data_container_X0”,
type: {
template: “

height: 48,
x_count: 5,
y_count: 2

dpDataX = new dataProcessor( "dataX.php" );
dpDataX.init( dataX );
dpDataX.setTransactionMode("GET", false);[/code]

and on the server side (dataX.php):

[code] require_once( “…/codebase/connector/dataview_connector.php” );
require_once( ‘…/config.php’ );
error_reporting(E_ALL ^ E_NOTICE);

$conn = mysql_connect( $server, $user, $pass );
mysql_select_db( $db_name );

$data = new DataViewConnector( $conn, "MySQL" );

After I drag a new element to the dataX view, the database is not updated, the log.txt shows error message:

while the debug window shows the parameters are null and the response is empty xml file

What am I doing wrong here?

As you are using non-standard mode

   dpDataX.setTransactionMode("GET", false);

Connector will not be able to detect update command. To work, it must be set as

   dpDataX.setTransactionMode("POST", true);

Also be sure that connector.js is included on the page.

Stanislav, as always you’re the one who saves the day :slight_smile:

It was connector.js missing from the include list and the transaction mode set inproperly. After corrrecting the code and including connecter.js the changes save to to db.

However, I still cannot do what I need.

I must block saving the changes triggered by drag and drop actions and send all the data at once manually (after click on “Save” button). I figured I’d need “onBeforeDataSending” event in order to block the default behaviour. But it appears that dpDataX.sendData() does not trigger the mentioned event at all. Nor it sends the data via dataProcessor.

Or maybe I’m doing this all wrong again?

Try to use


will block auto-sending, so data will be sent only when you trigger it manually by dp.sendData();
Also, you can use

dp.setUpdateMode("off", true); 

this mode is similar to above one, but it process dnd actions differently. Normally dnd in the component is processed as combination of insert|delete operations. But this above command it will be processed as single “update”

Lovely, dp.setUpdateMode(“off”) did the trick! I can’t believe it was so simple :slight_smile:

Thank you one more time Stanislav! I do hope I should be ready for deployment of my app soon so I can place an order for the pro version and support you guys.

Many thanks again!

Thanks for the assists! I was stuck with my code for the same reason, thanks for clarifying
