Can you clarify what the problem? In general, it can be added to php page the very similar way as to html, you add a script/link tags and required divs to a markup
Problem is related to scaling of scheduler, it will not show inside the divs, probably because some css is causing issues on the height.
I have tried your suggested solution, but I might be doing something wrong. Bellow is code. I have added dhtmlxscheduler_limit.js as suggested and paths are correct.
Make sure that div where you initialize the scheduler has a default height. Scheduler will adjust it’s sizes to the sizes of the container, so if the div is collapsed - scheduler won’t be visible
The weekend color did work all time. Just me that did not see it. I have my calendar for month view, and first by checking week view I noticed that it do work.
It works find on day and week, but not on month view.
