Filtering with regex

Hi, i would like to implement AND option with fnFilter. How to do that?

I am representing a list of projects in datatable. One project-one row. Each project has some features. So i took id's of features for each project and created CSV string from it. This is hidden column for each project.

I have list of checkboxes with all features. How to implement filtering with this. (List only those products that have all of selected features)

For example one project has this hidden-column: 'feature-1;feature-2;feature-3' and i want to apply filter for feature-1 AND feature-2.

I have looked into source code of a project and based on regex this should work table.fnFilter('feature-1 feature-2'), but ti doesn't :((

Please help.

    Hi mnovakovic,

    You are right, it should 'AND' automatically. I don't see any reason why that you have wouldn't work, and with a quick test here, it does appear to do what is expected. Could you post and example page which fails as you describe?

    you have that cool regexp string builder (simulating AND instead of ' ') ONLY if your column parameter is not defined (searching on all columns). But for some reasons this is not working for me.

    I set searching on specific column, where this "AND" automatic regexp builder is not created. Actually, you are not splitting on ' ' and creating this regexp, but only search for whole string - param. So i created whole regexp string as you did in search on all columns, and set third param in fnFilter to false and i got what i needed :)).

    It took me a lot of time, but it finally worked :D

    Hi mnovakovic,

    Good to hear you got what you wanted working in the end!

    You are quite right - I don't use my regular expression for single columns. I had kind of been assuming that individual column filtering would be only on one word, but that appears to be a bit of a weak assumption on my part. At the same time the global filtering takes all of the rows and will match the words in any order. Sorry I wasn't quite clear that this was what you were looking for on a single column. Love that regex switch :-)
