multiple wordpress custom post meta values

Question

I'm pretty hopeless at PHP, so I figured I'd ask for a bit of help!

I'm using WordPress as a CMS for a music agency site at daviesmusic.com and have lots of extra information for the various artists via custom fields. So far, I've just retrieved the custom field values one by one, like so:

<?php
    //audio title
    $audio_title = get_post_meta($post->ID, 'audio_name', true);
    if ($audio_title) :
?>

    <p><?php echo $audio_title; ?></p>

This works fine, only I have lots of custom fields that all require different outputs. I have for instance a photo for the artist, an audio file, the title of the audio file and some notes about the audio file, like so:

    <?php
    //profile image
    $profile_pic = get_post_meta($post->ID, 'profileimage', true);
    if($profile_pic) :
?>

    <img class="post-thumb-single" src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo $profile_pic; ?>&a=t&h=278&w=278&zc=1" alt="<?php the_title(); ?>" />

<?php   
    endif;
    //photographer
    $photographer = get_post_meta($post->ID, 'photographer', true);
    if($photographer) :
?>

    <p id="photographer">Photographer: <b><?php echo $photographer; ?></b></p>

<?php
    endif;
    //audio title
    $audio_title = get_post_meta($post->ID, 'audio_title', true);
    if ($audio_title) :
?>

    <h4 class="nsmb">Audio files</h4>

    <p><?php echo $audio_title; ?></p>

<?php
    //audio file
    $audio = get_post_meta($post->ID, 'audiofile', true);
    if ($audio) :
?>


<p class="audio" id="audioplayer_1">Sorry, there was a problem loading the file.</p>
<script>AudioPlayer.embed("audioplayer_1", {soundFile: "<?php echo $audio; ?>"});</script>


  <?php
    $audio_credits_1 = get_post_meta($post->ID, 'audio_credits_1', true);
    if ($audio_credits_1) :
  ?>

    <p class="audio_cred"><?php echo $audio_credits_1; ?></p>

    <?php
        endif; endif; endif;
    ?>

Lots of code. I'm sure there must be a more efficient way to retrieve the values! Any ideas?!

Cheers

Answer 1

Take this example from here:

$custom_fields = get_post_custom(72);
$my_custom_field = $custom_fields['my_custom_field'];
foreach ( $my_custom_field as $key => $value ){
    echo $key . " => " . $value . "<br />";
}

This will cycle through all specified custom values for the post (id #72 in this example, you can get yours using $post->ID as you have in your code). You can use $key to print the field name, and $value to print the value of that field. You can get more granular with how they're displayed using an if elseif else statement or a switch.
