I need a very simple frontend script and a backend admin area to do the following: our client runs an adoption agency for cats.

In the admin area he wants to create 5-10 fields of information (the amount of fields will vary and he must be able to add/delete fields) in which he will add details like the color of the cat, the cat's name, a history of the cat, etc.

Some of the fields are textfield and some are textarea and some are image fields for uploading jpeg, jpg, gif, png.

Then on the frontend he wants to be able to do 2 things:
1) He wants to create different types of searches: some are fulltext search, some are dropdown windows based on his criteria, and others are textfield searches of specific fields.

2) Be able to show the search results base don certain fields. Sometimes he might want to show only 2 fields in the search results, but sometimes he might want 5 or more fields in the search results. Also, he might want to alphabetize the search results based on a certain field's output.

The most important part of this is that our client will embed this script using PHP includes into another PHP-based CMS (either Wordpress or Joomla or Xoops), so your script must run independently and not cause confusion either for the PHP or the database. Also, it will run on Unicode using UTF-8 as the output.

I know Joomla and Xoops already have some of these plugins ready to use for searching directories, but we need a simple STANDALONE application.
