Custom Fields

    I have numerous custom fields working on different pages of my blog, but for some reason on one page they just won’t work!

    All I am trying to do is display an image using the following code:

    <img src="<?php $key="thumbnail"; echo get_post_meta($post->ID, $key, true); ?>" width="250" height="120" alt="thumb"/>

    And a backgroud image using:

    <div id="portfolio-feature" style="background:#000 url(<?php $key="background"; echo get_post_meta($post->ID, $key, true); ?>) center center;"></div>

    They are both within the loop and if I use <?php the_meta(); ?> I can see that the key values are returned fine, but for some reason they just don’t work in the img src

    Would be most grateful for any help!

    Hi Sorry it’s on a local server so I don’t have a URL, but here is the code for the page, would be most grateful for any ideas:

    <?php
/*
Template Name: Portfolio-detail
*/
?>
<?php
require 'header-portfolio.php';
?>

<?php while (have_posts()) : the_post(); ?>

<div id="portfolio-feature" style="background:#000 url(<?php $key="background"; echo get_post_meta($post->ID, $key, true); ?>) center center;">

<div id="slider">
<?php the_content('') ?>
<img src="<?php $key="thumbnail"; echo get_post_meta($post->ID, $key, true); ?>" width="250" height="120" alt="thumb"/>
</div>

</div>

<div id="content-wrapper">

<div id="content">

<div class="content-left portfolio-page">

<div id="buttons">
        <a href="#" id="btn-prev"></a>
        <a href="#" id="btn-pause"></a>
        <a href="#" id="btn-play"></a>
        <a href="#" id="btn-next"></a>
</div>

<h1><?php the_title('') ?></h1>

<?php endwhile; ?>
<?php wp_reset_query(); ?>

</div>

</div>

<?php get_footer(); ?>

    Sorry it’s on a local server so I don’t have a URL…

    Fair enough… and the only acceptable excuse. ☺

    I don’t see any reason to set the $key variable. I’d just write the key into the function and I’d put quotes around the url() string like so: style="background:url('<?php echo get_post_meta($post->ID, "background", true); ?>'). Minor points though. I don’t see why your code is failing. Load the page, view-source, and see if everything looks right. You might check permissions on the images too.

    Thanks apljdi – I tried that, but no joy.

    However I think I’m beggining to see the source of the problem: Does WordPress treat template pages differently?

    I’m trying to achieve this on a post that has a template assigned to it so I detached the post from the template and added the custom field code to single.php

    style="background:#000 url(<?php echo get_post_meta('<?php echo get_post_meta($post->ID, "background", true); ?>'); ?>

    when I reload the page the post then loaded from the default single.php and the background image works fine.

    Soooo…

    I copied all the code from single.php into my template (so the two files were exactly the same) and then re-assigned it to the post – I reloaded and . . . . it’s gone!

    The code works for me, though of course I had to use a meta_key that exists in my install. What exactly does your echo get_post_meta statement return? And why do you have nested get_post_meta’s?

    Does WordPress treat template pages differently?

    Well, yes… but not in a way that should effect this. How are you ‘assigning’ the post to the page?

    Jeez sorry – I posted that code incorrectly, I didn’t mean to nest anything (this is frying my brain!).

    I meant to post:

    style="background:url('<?php echo get_post_meta($post->ID, "background", true); ?>')

    i.e. the original recommendation by yourself!

    My get_post_meta statement returns nothing – the background url is just blank! (except the single quote marks).

    However if I use the <?php the_meta(); ?> function it returns the two custom fields exactly as I would expect them to look.

    Ok. That is getting somewhere. Either $post->ID is empty or there is no meta_key = “background” in the database associated with the post. Echo $post->ID by itself to see what happens.
