get_template_part() – post-meta not working?

4 Views

Maybe I simply do not understand what get_template_part() is doing …

I have a file called event-list.php that should work as template for other pages and files so all my events (a custom post type) get listed!

Inside this event-list.php I have this … 

<?php
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
    $wr_event_fields = get_post_custom();
    $event_date_timestamp = $wr_event_fields['_wr_event_date'][0];
    $event_date = strftime('%d.%m.%Y', $event_date_timestamp);
    $event_time = $wr_event_fields['_wr_event_time'][0];
    $event_speaker = $wr_event_fields['_wr_event_speaker'][0];  
    //get_template_part( 'event-item' );
?>
    <!-- event-item.php -->
    <div id="event-<?php the_ID(); ?>" <?php post_class(); ?>>

        <div class="event-date"><?php echo $event_date; ?></div>
        <div class="event_time"><?php echo $event_time; ?></div>
        <div class="event-speaker"><?php echo $event_speaker; ?></div>
        <div class="event-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></div>
        <div class="event-description-excerpt"><?php the_excerpt(); ?></div>

    </div>
    <!-- event-item.php -->

<?php endwhile; ?>

So what I want to do is include another template inside of event-list.php named event-item.php which only holds the layout of an event. I want to use this event-item.php maybe later also in different loops. It should just be the markup for each single event-item on my website. If I make a change inside of this even-item.php template all “events” in any of my loops on my entire website should change.

The problem I have with this is the one in the above sample code.
I use get_template_part( 'event-item' ); to include the event-item.php layout structure within my loop. And I get its custom post-meta outside of this template. However that does not work!

As you can see in my sample above I have to copy the entire layout structure from my event-item.php inside of my event-list.php so the post-meta stuff is filled in.

Any ideas what I don’t get here or what I’m doing wrong here?

Thank you in advance.

  1. Try globalizing $post inside of event-item.php.

    Also: be sure to call wp_reset_postdata() after you close your $loop while loop.

    e.g.:

    <!-- event-item.php -->
<?php 
// globalize $post
global $post; 
?>
<div id="event-<?php the_ID(); ?>" <?php post_class(); ?>>

    <div class="event-date"><?php echo $event_date; ?></div>
    <div class="event_time"><?php echo $event_time; ?></div>
    <div class="event-speaker"><?php echo $event_speaker; ?></div>
    <div class="event-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></div>
    <div class="event-description-excerpt"><?php the_excerpt(); ?></div>

</div>
<!-- event-item.php -->

    and then:

    <?php 
endwhile; 

// Restore $post global to the primary query
wp_reset_postdata();
?>

    Edit

    Assuming the problem is just the post meta data, I would suggest moving the post meta data variables inside loop-item.php. Only a guess, but perhaps your local variables aren’t getting passed through the include() function that is part of get_template_part().

    So, like this:

    <!-- event-item.php -->
<?php
// Define these here, inside loop-item.php
$wr_event_fields = get_post_custom();
$event_date_timestamp = $wr_event_fields['_wr_event_date'][0];
$event_date = strftime('%d.%m.%Y', $event_date_timestamp);
$event_time = $wr_event_fields['_wr_event_time'][0];
$event_speaker = $wr_event_fields['_wr_event_speaker'][0]; 
?> 
<div id="event-<?php the_ID(); ?>" <?php post_class(); ?>>

    <div class="event-date"><?php echo $event_date; ?></div>
    <div class="event_time"><?php echo $event_time; ?></div>
    <div class="event-speaker"><?php echo $event_speaker; ?></div>
    <div class="event-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></div>
    <div class="event-description-excerpt"><?php the_excerpt(); ?></div>

</div>
<!-- event-item.php -->

    Also, to avoid undefined variable notices, you should define your variables using isset() conditionals; e.g. change this:

    $event_date_timestamp = $wr_event_fields['_wr_event_date'][0];

    …to this:

    $event_date_timestamp = ( isset( $wr_event_fields['_wr_event_date'][0] ) ? $wr_event_fields['_wr_event_date'][0] : false );

  2. Instead of doing:

    get_template_part( 'event-item' );

    do this instead:

    get_template_part( 'event','item' );

    get_template_part expects the filename will be: parameter1-parameter2.php

    Also make sure that you declare the variables you want to use as globals, else they will be out of scope and not be shown:

    global $event_date, $event_time, $event_speaker;
