Hi!

I am trying to do a filter save functionality for my clients, so they don't have to do the filtering they need every time they visit my website (those are registered users). Since wpDataTables support pre-filtering through URL, I thought that maybe it would be possible to write a Javascript code which could check the states of checkboxed and other inputs and then compile a link that would be saved for user.

The problem is that when checking out code via Inspect Element feature in my browser I don't see any state changes (that is no attributes are being added to checkboxes), so that must be happening somewhere in the background through JS. I am not using server-side processing.

So is there some kind of a function that I could tap into to see the changes in filter inputs, so I could track them and use to compile a custom URL for future filtering?

Also, is there a way to show all the items in the table through URL? Like there is an option to show 25, 50 or so entries, can I use any URL to show all the entries? Want to use this for my custom printing script, because right now it prints only what is visible on the screen.

Great. Thank you, I will work from there.

If I may one more question regarding URL filters. How should URL key look if I want to pre-filter multiple ckeckboxes or multiselect dropdown?

?wdt_column_filter[1]=Checkbox1,Checkbox2 or similar do not seem to work.

Wonderful. Thank you!

Hi again.

Going a bit back with one of my initial questions: is it possible to show all entries inside table through URL. The answer was no. Maybe there is some kind of a way to force table show all elements by Javascript? Any way to pass wanted variable (my case '-1') and trigger table redraw?

Understood. In that case maybe you could point me in direction of files where I could find the function, responsible for table pagination (how many results are showing)?

And could I ask to add this feature to your to-do list: allow changing value of "Show ** entries" by URL (like it is possible with filters)? Something like ?wdt_pagination=show_all.

And what about Javascript part? There must be a code that waits for a state change on that button/select and then goes for PHP to retrieve data.

Hi! I managed to find functions that I can use to push redraw of table when I want:

wpDataTables.{table_id}.fnSettings()._iDisplayLength = -1; // number of results to show
wpDataTables.{table_id}.fnDraw(false);

{table_id} - ID of the table to redraw.
