Hi
I searched a lot for my issues, but did not find what I want, I also Posted a Question on stackOverflow but did not get the response and then I just got here and hope may be someone have the same issue in past or have some sort of code which will help me to fix my issue.
I have a filter section, where user can filter product by Size, Color etc. I somehow did the filter code but now I am stuck in the ajax issue. Issue is that When color or size checkbox is empty then it throw error of foreach loop
I know the error is because of empty data in variable. There is also an issue in my query. The filter result is not 100% correct and I say that because I did
and the Query I get is wrong [ I am sure of it 100% ]. I have attach the var_dump() result for reference and clearness,
. I also need to control the empty or null section, like if the checkbox is unchecked then it will not send / post the value to the controller...

Please post your ideas / codes / helpful links anything you can, Please make sure to use the CI Active Records for queries, because I don’t want to do it in plain query.
Any help will be highly appreciated.
Thanks.
