Dhtmlx Scheduler Filter Data from PHP

Hi there, I have some issue trying to filter data from MySql db dinamically. What i should want to do, is send ‘id’ value and filter data using render_table (SOMEquerysql). To be more clear, in my MySql db there are this fields:
ID
IdEmp
Employee
start_data
end_data
text

Can someone tell me how select events concerning only employee with IDEmp = “3”? (i.e)

Thanks in advance

I Have forgotten an important thing:

I’m using html and php.

Sorry

Hello,
please check this article
docs.dhtmlx.com/connector__php__filtration.html

Thanks Aliaksandr, I saw this article, and it works properly!! Great.
However I have ask you something else, hoping you can help me .
I have used this command to filter data before loading my scheduler

some.php?connector=true&dhx_filter[2]=name_i_need_to_filter

Is it possible to assign this name to a variable using a field of my html page, like an input text or something else?

Thanks
