One question I come across a lot regarding custom fields is how to only retrieve posts based on a custom field. For example, if a post has a custom field of “MyData”, someone might want to only retrieve that particular post. The WordPress Codex has a technique for retrieving posts based on custom fields, which consists of writing your own query and going through the results. The technique in the Codex is good, but I’ve found a re-usable way one can retrieve only posts with certain custom fields. The technique I use makes use of two custom functions placed in a theme’s “functions.php” and a custom WordPress Loop.

I am not sure why it was not integrated into the WordPress admin though it does honor the WordPress user profile. It uses special Zip and Mysql backup backup classes from inside PHP and does not require the use or permission of passthu().
