Custom Fields in WordPress are the developer’s catch-all solution for any specific need that isn’t already covered by WordPress’s broad selection of plugins. In it’s most basic use, you can input specific content into custom fields and then present them in the post page or other places inside the loop through your theme. A good example of this is when using WordPress for a shopping cart style site. You can input all your pricing information as custom fields, making it easy for the client to input the data and giving the designer flexibility on how the information is formatted and presented. For a real estate site, the custom fields can contain a plethora of details about the property in the post. And the best part is that as these fields are in a separate location in the database that can be isolated and queried. Allowing users to request to see all single bedroom listings from the database without utilizing tags or categories.
