Simple WordPress Custom Field Template

This is a simple way to add custom fields to your posts without much hassle. Download the code and change the example fields to your own specific needs and voila, the custom fields are located on your post. In this example, let's say that you (or your client) review movies. In addition to the text of the review, you want to have three associated custom fields that show up without having to use the dropdown each time to select the custom field. There are custom field plugins that let you dynamically create these, but for this case, there is only one template and this solves the problem quickly. The three custom fields defined below are: Movie Rating (_movie_rating) Movie Running Time (_movie_running_time) Movie Director (_movie_director)
