Fetching specific values for meta data…

  • Site: we-rate-stuff.com

    I’m trying to use WordPress’s custom fields to inject a score onto post reviews. This is how I want it to work:

    1. Select key/name “Score” in the custom fields section
    2. Input numerical score ranging from 1 to 7
    3. On individual post page, a custom image (1 of 7) will be display depending on the meta data value (1 through 7)

    Right now I’ve deduced how to retrieve the post’s meta data insofar as displaying the same static image so long as there is a “Score” attached to the post, but I can’t figure out how to retrieve the meta data value and have a custom image injected as a result.

    Any help/advice/fingers in the right direction would be hugely appreciated.

  • how to retrieve the meta data value

    $value = get_post_meta($post->ID, 'Score', true);

    how are the images organized?

    if they have numbers corresponding to the score in the image name (score1.jpg; score2.jpg …), then something like this might work:

    <img src="<?php bloginfo('stylesheet_directory'); ?>/images/score<?php echo get_post_mata($post->ID, 'Score', true); ?>.jpg" alt="" />

    (assuming that the images are in the /images folder of the theme)

    (utterly untested)
