Multiple filters and request extender

Hi
I use extenders=`request` with milti-filter (ditto_filter_1, ditto_filter_2, ....)

My Ditto call:

[!Ditto? &parents=`57` &depth=`1` &tagDelimiter=`,` &tagData=`placeType,cookery,disposition,checksum` &hiddenFields=`placeType,cookery,disposition,checksum` &tagMode=`onlyAllTags` &extenders=`request` &debug=`1`!]

It works when I set ditto_filter_1="placeType,text,7" ditto_filter_2="cookery,test,7" ..... variables in URL
Ditto displays all documents that contains ’test’ in search field (tv).
But I need Ditto to display all documents where ’test’ == tvvalue. Following the documentation, I have to set ’1’ in filter mode. But it doesn’t work....... No documents found....
Help me, please.

EDIT:
After few tests...
If I set ’1’ in filter mode Ditto displays only documents that have ’test’ as THE ONLY tv value. And if document tv has values ’test’ AND ’test2’ Ditto ignores that document...
I can’t use filter mode ’7’ because in that case Ditto display documents that have tv value==’somethingtest’ and this is not what I want...
Sorry for my English.

1. What type of tv are each of your template variables?
2. Mode 2 or 8 are what you want since filter will REMOVE all documents that match the criteria. so if joe != foo it will REMOVE it

Variables have checkbox type (comma delimited list).
I make some changes, and now it works as I wish! 
in filter.class.inc.php i add:

case 9  :
    $unset = 0;
$availabletags = explode(",", $value[$this->array_key]);
foreach ($availabletags as $availabletag) {
    if (($this->filterValue) == $availadletag)
  $unset =1;
}
break;

with this addition my template variables may have several values. For example, (tv)placeType = "bar,restaurant" ...
whithout this addition if we want to show only documents that have ’bar’ (ditto_filter_1=’placeType,bar,1’) Ditto shows the only ’bar’ but no ’bar,restaurant’
if we use filter mode ’7’ to display documents that contains ’bar’ Ditto shows ’bar’, ’bar,restaurant’, but also ’sushi-bar’, ’blablabarblabla’....

What you are describing is exactly what tagging is.

You would use &tagData=`foo` &tagDelimiter=`,` &tagMode=`onlyAllTags` to accomplish what you describe. Then you would pass the tags to the snippet via the tags url parameter. You can filter by more than one tag by saying ?tags=tag1,tag2 in the url (since you tags are comma separated).

Yes, tagging works, but I have form with several dropdowns to select filter values.. If it would be possible to use ditto_tags_1="tag1" ditto_tags_2="tag2" ....
So, that solution works for me and maybe for somebody else.

Great snippet, Mark!

Maybe something along the lines of tag_1 , tag_2 , tag_3 ...
Please file a feature request for this in the bugtracker. Thanks!
