I am looking for an advanced search/filter feature to be developed that I can add to my Wordpress website.
I wish for this feature to allow visitors to view posts within a category as normal, but to then also have the option to select multiple category tick boxes from 3 separate columns (based on categories and sub categories), which will then filter the posts shown in order to only display posts that appear in the ticked categories.
User is viewing category called 'friend' which displays list of all posts under this category.
Above the posts, I want options for additional categories to be selected, which then narrows down/filters the post results shown to only show relevant posts.
See this image for example - [url removed, login to view]
So, for example, if the category '£10-£50' is selected and also the category 'Sporty', and category 'Personal' then it only shows posts that are under ALL 4 categories (Friend + £10-£50 + Sporty + Personal). (it should automatically know its in category 'friend')
If additional categories are also selected, such as '£50-£100' then is will show posts that are under ALL 4 categories again (Friend + £10-£50 or £50-£100 + Sporty + Personal), but with the option of being in EITHER £10-50 or £50-£100 this time!
So out of the 3 option columns, the results shown would need to be at least 1 from each column. 'Any' will be selected by default to display posts in any of the categories listed.
I would also like it to display the amount of posts there are in real time using ajax if possible, depending on what selections are ticked. (see example above).
I am using Wordpress version 2.8. a plugin would be preferred with the option to configure and to be able to place the filter where I want it, but just the code would be fine if not, as long as it is configurable.
Hope this makes sense, please let me know if not!
