I am developing a WordPress theme but I'm having trouble with the_excerpt();.
I only wish to use the Custom Excerpt field and to show that when it contains content. But, if I don't write anything in the 'Custom Excerpt' field, in the admin panel, it will then show the default. I don't want this.
I need something like the_custom_excerpt();, which only shows content IF there is any contained within 'Custom Excerpt'.
