Conditional tag if $customfield exists

    I am creating the page.php template for a new wordpress theme. When the custom field $post-image is included in the page, I want it to display with 2 columns where the $post-image is in the left column and the content is in the right column. When the $post-image does not display, I want the content to display in a div of the full width of the page.

    See how on the index page the $post-image is included and the content displays how I’d like; however, on the about page there is no input for the $post-image, but yet the content is still displaying with the two columns. The code I have so far is:

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

    <?php if ( $post-image ) { ?>

    <div class=”left”>

    <img src=”<?php echo get_post_meta($post->ID, ‘post-image’, true); ?>” alt=”Image for Page #<?php the_ID(); ?>” />

    </div><div class=”right”>

    <?php } else { ?>

    <div class=”post”><h2>“><?php the_title(); ?></h2>
    <?php } ?>

    <div class=”entry”>
    <?php the_content(); ?>
    </div>

    </div>
    <?php endwhile; else: ?>

    <p>Sorry, no posts matched your criteria.</p>

    <?php endif; ?>

    Thanks!

  • Almost right, but in the wrong way:

    In your case $post-image always will be undefined, since you didn’t query it yet.

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
  <?php $image=get_post_meta($post->ID, 'post-image', true);
    <?php if ( $image ) { ?>

      <!-- layout with image -->

    <?php } else { ?>

      <!-- layout without image -->

    <?php endif; ?>

  <?php endwhile; else: ?>
    <p>Sorry, no posts matched your criteria.</p>
  <?php endif; ?>

    Amazing, thank you! I’m learning as I go but it’s really fun. I appreciate the help.

    Peter, when I try that block of code I get

    'Parse error: syntax error, unexpected '<' in [...]single.php on line 36'

    with line 36 being ‘ <?php if ( $image ) { ?> ‘

    Any idea what I might be doing wrong?

    Thanks,

    Nathan

    Nathan,

    You need to post the lines before it. It looks as though maybe you’ve already opened the PHP syntax.

    Here’s what I’m working with:
    https://wordpress.pastebin.com/1rCXHWz0

    it’s loaded with custom fields; so far all of them are used on each post, I need to add one that only appears if it exists/has content.

    At a minimum, this line needs a closing PHP ?>

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

    so it would be

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

    I’ve actually gotten this to work using the other method I found elsewhere in the forums:


    <?php
    $key = 'image';
    $themeta = get_post_meta($post->ID, $key, TRUE);
    if($themeta != '') {
    echo '<img src='.$image.'>';
    }
    ?>

    If I had my preference I wouldn’t go this route because it requires echo-ing the HTML in quotes and stringing it to the variable. But that aside, does it make any difference which method I use?

    OK let me try that, thanks.

    Michael,

    Then I get a

    unexpected T_ENDIF in […]single.php on line 41

    Michael’s suggestion was correct and I’ve edited the rest of the code here:

    That did it. Thanks!!

    Glad that sorted it.

    Thanks for this!!
