Which dhtmlx suite sample to follow?

The dhtmlx suite download contains several samples.

I am using grid with php connector and render_sql to load data from mysql db using joins in the sql statement.
I understand that php connector does not handle crud operations when joins are used.

What is the correct sample/best practice to follow to get the crud operations to work?
I have read the online documentation but a working sample to follow would help much to understand.

Thnx

Please, try to refer to the dhtmlxDataProcessor component:
docs.dhtmlx.com/dataprocessor__index.html
You can find the corresponding samples in the connector package.

Thank you!
