This version adds multiple key=value check, which means that now you can have URLs like this:
http://yoursite.com/?s=anything&key1=valueA&key2=valueB...
http://yoursite.com/category/news/?key1=valueA&key2=valueB...
I’ve also added autosuggest to the input fields in the Settings Page which will give suggestions based on the existing meta keys on your site.
Any ideas for an interface to construct such URLs are welcome (an advanced search box? etc).

Nice work.
About an idea to construct URLs:
Take a look at my site that uses WP Dropdown Metas: http://tr.im/9iaq
Now imagine if you select one value from a dropdown, but instead of then navigating to that query, the widget locks that dropdown, and then adjusts the other dropdowns to only show the possible values from posts that have already been limited by the previous selection.
Interesting (now I finally understood what you meant).
As the number of possible posts are limited with each dropdown lock-in and the other dropdowns then adjusted accordingly, their titles can also be previewed below the widget before the actual query is run for showing in the loop.
I love this plugin, and now I’m also looking for an Advanced Search Box, any news on that?
I haven’t gotten around to it yet, but I do intend to add one.
I found this as well last night: http://www.dyasonhat.com/wp-smart-sort-premium/
It looks cool, but I can’t get it to work on my install due to a Zend Optimizer conflict…
I prefer your system because it allows more access to the URL.
Yeah, that’s the main reason I wrote it.
Ahah! So you don’t recommend WP Smart Sort Premium?
Well, besides the fact that it costs $35 and the only way you can access sorted posts is through a box, it’s a nice plugin. I’ve only tested the free version.
I tested the free version as well, and funnily enough, it seemed to conflict with yours. I was trying to use the same custom field for sorting also.
I haven’t but I guess the conflict is due to the fact that each plugin uses a slightly different method of getting the right posts.
Good point…
The URL accessibility of your plugin is really cool, just need to build my own form. I guess that should be pretty easy…
If you do and are willing to share, please let me know so that I might include it in a future version of the plugin.
Certainly! I’ll keep you posted…
Dunno if its a bug, but when you use : http://yoursite.com/category/news/?key1=valueA&key2= with no value for key2 (empty so), its display a not found message.
Would be easier to make an advanced search feature if you add a super value that get all the data for a custom field, for example (but maybe it already exist in Wordpress, dunno!)
I’ll look into it.
Fixed in 0.8.1: You can have empty values for one or more keys.
The search form will be similar to the Filters box on trac.
Hi Scribu, will definitely be trying this out (since v0.7) … the multiple select looks exactly what I was looking for … thanks, I’ll let you know how it goes.
