Using the Post’s Custom Fields Data In Sidebar

    Basically, on my single.php I have my post laid out in the loop as normal.

    I then include a seperate sidebar.php named sidebar-single.php as it will be different to the main index.php version.

    In my actual post I set a custom field with some text I use to dynamically include a certain html file into the sidebar, depending on the post.

    Say i set the custom field to “apples”, I want the code in the sidebar to automatically query the CURRENT post and look for the custom field and then output like a php include(/includes/apples.php)

    I have done something similar inside the post loop where I can incorporate a banner depending on the custom field set, but I am struggling to get this working in the sidebar.

    This is probably straight forward, but I am not much of a programmer to understand.

    A simpler way to explain and do this would be to get the current single post title to be displayed in the sidebar outside of the loop.

    Is this possible? Thanks in advance!

  • Since you are talking about doing this on single post pages outside the loop, you can use this method to get the post ID:

    global $wp_query;
$post_id = $wp_query->post->ID;

    Then you can use the get_post_meta function with the post ID:

    get_post_meta($post_id, $key, $single);

    Hope that helps.

    Thanks for the response. I’ve tried the above method and echo’d out the post id to see if it works for each single post but it does not.

    <?php
	global $wp_query;
	$post_id = $wp_query->post->ID;
	echo $post_id;
	?>

    It gets the post id from one post, which is not even the current post in the browser. If that makes any sense?

    Okay I think you got a little confused. This code needs to go within the loop.

    <?php
	global $wp_query;
	$post_id = $wp_query->post->ID;
?>

    Then you can use this code outside of the loop.
    <?php get_post_meta($post_id, $key, $single); ?>

    One more thing if your sidebar is a seperate file like sidebar.php and it’s called from single.php then you’ll need to make sure that you use this code.

    <?php
	global $wp_query;
	global $post_id;
	$post_id = $wp_query->post->ID;
?>

    You also should use this code to wrap your sidebar code.

    <?php (if is_single()){
get_post_meta($post_id, $key, $single) } ?>

    Awesome that worked after a little bit more of fiddling around [my fault due to lack of php knowledge I guess]

    In my sidebar-single.php I had to put this bit of code above the get_post_meta part:-

    <?php
	global $post_id; ?>

    Thanks a lot guys, I am totally chuffed! Appreciate your help! =)
