I have this include … event-list.php

<?php
/**
 * The loop that displays upcoming events
 */
?>

<ul class="event-items">
<?php

    $yesterday = time() - 24*60*60;
    $args = array( 
        'post_type' => 'wr_event', 
        'posts_per_page' => -1, // show all posts 
        'meta_key' => 'event_date', 
        'orderby' => 'meta_value_num', 
        'order' => 'ASC',
        'meta_value' => $yesterday,
        'meta_compare' => '>'           
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
        get_template_part( 'inc/event', 'item' );
    endwhile;
    wp_reset_postdata();
?>
</ul>

As you can see it's a custom query that compares a meta_key with the current date and only retrieves posts that are "newer" than yesterday.

however in my archives I want to do it the other way around.

On my index.php I have this

<?php get_template_part( 'inc/event', 'list' ); ?>

So this template above is getting executed and only retrieves events that are fresher than the last 24hours.

In my archives.php though I'd like to reverse the meta_compare value from ">" to "<" so I get the rest of the posts.

Is there a clever way of doing this?

So in my archives.php I have this as well …

<?php get_template_part( 'inc/event', 'list' ); ?>

Can I somehow pass the 'meta_compare' value to this template? So I can have and use the same template file in my index.php and in my archives.php but with different 'meta_compare' values.

Any ideas on that?

Why don't you use a simple function with an argument to achieve that, the code is something like this:

function wpse63585_event_list( $fresh = true )
{
    echo '<ul class="event-items">';

    $yesterday = time() - 24*60*60;
    $compare = $fresh ? '>' : '<';

    $args = array(
        'post_type' => 'wr_event',
        'posts_per_page' => -1, // show all posts
        'meta_key' => 'event_date',
        'orderby' => 'meta_value_num',
        'order' => 'ASC',
        'meta_value' => $yesterday,
        'meta_compare' => $compare,
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
        get_template_part( 'inc/event', 'item' );
    endwhile;
    wp_reset_postdata();
    echo '</ul>';
}

And then in your index.php, just call:

<?php wpse63585_event_list(); ?>

and in archives.php:

<?php wpse63585_event_list( false ); ?>

Another solution I can think about is you can register a global variable, like $wpse63585_fresh = true, and use that variable in your template part event-list.php to control the condition, like this:

In index.php:

global $wpse63585_fresh;

$wpse63585_fresh = true;
get_template_part( 'inc/event', 'list' );

In archive.php:

global $wpse63585_fresh;

$wpse63585_fresh = false;
get_template_part( 'inc/event', 'list' );

In event-list.php:

<ul class="event-items">
<?php
    global $wpse63585_fresh;
    $compare = $wpse63585_fresh ? '>' : '<';

    $yesterday = time() - 24*60*60;
    $args = array( 
        'post_type' => 'wr_event', 
        'posts_per_page' => -1, // show all posts 
        'meta_key' => 'event_date', 
        'orderby' => 'meta_value_num', 
        'order' => 'ASC',
        'meta_value' => $yesterday,
        'meta_compare' => $compare           
    );

    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
        get_template_part( 'inc/event', 'item' );
    endwhile;
    wp_reset_postdata();
?>
</ul>

Thank you, couldn't come up with this easy solution. I'll award you with the +50 as soon as it's possible. It says I have to wait for 22hours. Thank you again. –  mathiregister Sep 1 '12 at 8:58
    
Thank you, too :) –  Rilwis Sep 1 '12 at 16:06

But still, there are many cases requiring variable passed to the get_template_part(). –  BasTaller Sep 30 '13 at 19:06
