[resolved] If/then condition in custom field usage (3 posts)

    OK, I've been trying to work this out myself through reading help pages and experimentation, but I'm growing frustrated, so I'll ask for help.

    I am rebuilding a site for someone in which a small number of editors post articles from a large number of different writers. Most of those writers are NOT registered users, but a few are. As I want the real author of the article to show up on the post, not necessarily the creator of the post, I use custom fields to specify the writer (name=”author”, value=author’s actual name). Then, in my theme files, I replaced:

    <?php the_author_posts_link(); ?>

    with

    <?php if ( get_post_meta($post->ID, 'author', true) ) { ?><?php echo get_post_meta($post->ID, "author", $single = true); ?><?php } ?>

    So far so good. In any post that has a custom “author” field specified, the pseudo author is displayed instead of the post creator. However, in posts in which a pseudo author has not been specified, no author shows up on the post at all. This is understandable, since there is no code to call it, and I have not used a "then" statement of any sort to specify what happens "if" there us no custom key set.

    I could just populate the custom field on every post, but since it interests me, I'd like to learn how to do satisfy the if/then condition for the sake of learning it.

    I've tried to use this bit of code, but it seems not to work:

    <span>
    <?php
    $author2 = get_the_author();
    $values2 = get_post_custom_values("Author");
    if (empty ($values2)) {
    echo "By " . $author2;
    } else {
    echo "By " . $values2[0];
    }
    ?></span>

    Anyone have any useful feedback?

    Untested but why not:

    <?php
    $author = get_post_meta($post->ID, "author", $single = true);
    if ( $author ) {
    echo $author;
    } else {
    the_author_posts_link();
    }
    ?>
