Custom column filtering
Custom column filtering
Hello,
i have this AJAX data provider: https://github.com/coderexample/datatable_example/blob/master/demo1/employee-grid-data.php
And i need integrate custom column filtering like this: https://datatables.net/extensions/fixedheader/examples/options/columnFiltering.html
However, it does not work, AJAX always returns all results. Ignores column searches and returns all results.
Does anyone have any type, what can it be?
I will be happy to provide any cooperation and additional information.
many thanks.

It would be worth looking at the supplied server-side scripts, as they will work with column searching. The Editor scripts, which can be used without Editor, can also do that, plus additional functionality.

I'm not sure what you think? In my opinion, the server-side script works like this:
And XHR ajax request is like (if two collumn search i write "ZDA"):
data.php?draw=9&columns%5B0%5D%5Bdata%5D=0&columns%5B0%5D%5Bname%5D=&columns%5B0%5D%5Bsearchable%5D=true&columns%5B0%5D%5Borderable%5D=false&columns%5B0%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B0%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B1%5D%5Bdata%5D=1&columns%5B1%5D%5Bname%5D=&columns%5B1%5D%5Bsearchable%5D=true&columns%5B1%5D%5Borderable%5D=false&columns%5B1%5D%5Bsearch%5D%5Bvalue%5D=ZDA&columns%5B1%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B2%5D%5Bdata%5D=2&columns%5B2%5D%5Bname%5D=&columns%5B2%5D%5Bsearchable%5D=true&columns%5B2%5D%5Borderable%5D=false&columns%5B2%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B2%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B3%5D%5Bdata%5D=3&columns%5B3%5D%5Bname%5D=&columns%5B3%5D%5Bsearchable%5D=true&columns%5B3%5D%5Borderable%5D=false&columns%5B3%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B3%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B4%5D%5Bdata%5D=4&columns%5B4%5D%5Bname%5D=&columns%5B4%5D%5Bsearchable%5D=true&columns%5B4%5D%5Borderable%5D=false&columns%5B4%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B4%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B5%5D%5Bdata%5D=5&columns%5B5%5D%5Bname%5D=&columns%5B5%5D%5Bsearchable%5D=true&columns%5B5%5D%5Borderable%5D=false&columns%5B5%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B5%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B6%5D%5Bdata%5D=6&columns%5B6%5D%5Bname%5D=&columns%5B6%5D%5Bsearchable%5D=true&columns%5B6%5D%5Borderable%5D=false&columns%5B6%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B6%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B7%5D%5Bdata%5D=7&columns%5B7%5D%5Bname%5D=&columns%5B7%5D%5Bsearchable%5D=true&columns%5B7%5D%5Borderable%5D=false&columns%5B7%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B7%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B8%5D%5Bdata%5D=8&columns%5B8%5D%5Bname%5D=&columns%5B8%5D%5Bsearchable%5D=true&columns%5B8%5D%5Borderable%5D=false&columns%5B8%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B8%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B9%5D%5Bdata%5D=9&columns%5B9%5D%5Bname%5D=&columns%5B9%5D%5Bsearchable%5D=true&columns%5B9%5D%5Borderable%5D=false&columns%5B9%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B9%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B10%5D%5Bdata%5D=10&columns%5B10%5D%5Bname%5D=&columns%5B10%5D%5Bsearchable%5D=true&columns%5B10%5D%5Borderable%5D=false&columns%5B10%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B10%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B11%5D%5Bdata%5D=11&columns%5B11%5D%5Bname%5D=&columns%5B11%5D%5Bsearchable%5D=true&columns%5B11%5D%5Borderable%5D=false&columns%5B11%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B11%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B12%5D%5Bdata%5D=12&columns%5B12%5D%5Bname%5D=&columns%5B12%5D%5Bsearchable%5D=true&columns%5B12%5D%5Borderable%5D=false&columns%5B12%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B12%5D%5Bsearch%5D%5Bregex%5D=false&columns%5B13%5D%5Bdata%5D=13&columns%5B13%5D%5Bname%5D=&columns%5B13%5D%5Bsearchable%5D=true&columns%5B13%5D%5Borderable%5D=false&columns%5B13%5D%5Bsearch%5D%5Bvalue%5D=&columns%5B13%5D%5Bsearch%5D%5Bregex%5D=false&order%5B0%5D%5Bcolumn%5D=0&order%5B0%5D%5Bdir%5D=asc&start=0&length=100&search%5Bvalue%5D=&search%5Bregex%5D=false
But data.php return stay all rows, this filter has benn ignored.
Can someone try to advise me? I will cooperate as much as possible. Thank you very much.
Summary: Instant search sends a request with a filtering request, but data.php ignores the request. :-(
Hi,
Your search term isn't in
['search']['value']
(which is global - i.e. all columns), rather it is specifically on column index 1:So the
WHERE
code you have above wouldn't pick it up.If I may suggest, rather than using the example you currently are, use our own SSP class. It will handle filtering (including column filtering) automatically for you.
A basic example of how to use it is available here for arrays, or here if you prefer to use object based data at the client-side (personally I perfect object based).
