    hello,

    i am trying to output the contents of a custom field (created through the More Field plugin) in the head area of my templates header.php with:

    <?php if ( in_category('5') ) {echo '<meta property="text" content="' . get_post_meta(get_the_ID(), 'custom_field', true) . '" />';}?>

    and it is currently outputting:

    <meta property="text" content="" />

    ie it is not grabbing the value in the ‘custom_field’.

    can someone please tell me how i can successfully grab the value of that custom field?

    thanks very much!

    The issue is that you are calling this outside of the loop. Thus the posts have not been set up yet.

    According to the codex
    http://codex.wordpress.org/Function_Reference/get_the_ID
    get_the_id()

    Returns the numeric ID of the current post. This tag must be within The Loop.

    When in header.php the loop has not yet been initiated. There is not yet a post ID # established so get_the_id() is returning null or false, i.e. nothing.

    You need a way to pass to header.php the post id of the post you want displayed on the page you are in the process of displaying.

    yes thank you, just in the process of posting this solution, thanks to this post.

    so the code that worked was:

    <?php if (in_category('5') ) { the_post(); rewind_posts();
echo '<meta property="text" content="' . get_post_meta(get_the_ID(), 'custom_field', true) . '" />';
} ?>

    thanks for your reply!
