WordPress Development Asked by Confused One on October 30, 2021
I am trying to put a header before past posts and after future posts.
I’m using get_posts() in a function to output the posts using a foreach loop for a custom post type ordered by date (meta key). If a post’s associated date is less than the current date (i.e., dates not in the future), I want to output some HTML.
if ($custom_post_date >= $today && $index === 1)
The problem I am running into is that the HTML gets output after the first post that is in the past. How can I output the HTML before the first post that meets the criteria? Is there a way to go back in the foreach loop or something to that effect?
<?php
$index = 1; // counts all items in query
$count = count($upcoming_posts);
$today = new DateTime();
$past = false;
foreach ($upcoming_posts as $posts) {
if ($post_date >= $today && $index === 1) : ?>
<h2><?php __( 'Upcoming Posts', 'sage' ); ?></h2>
<div class="wp-block-columns has-2-columns">
<?php else ($post_date < $today && $past === false && $index === 1) : ?>
<?php $wp_query->current_post -= 1; ?>
<h2><?php __( 'Past Posts', 'sage' ); ?></h2>
<div class="wp-block-columns">
<?php endif; ?>
<div class="wp-block-column">
<div class="wp-block-media-text alignwide">
...
</div>
</div>
<php if ( ($index % 2) == 0 && $end === false ) : ?>
</div>
<div class="wp-block-columns has-2-columns"> <!-- ends row every other iteration -->
<?php $end = false;
endif;
if ($count == $index ) : ?>
</div> <!-- ends final row -->
<?php endif;
} ?>
You may have already figured this one out, but here's two examples how to do this. In both of my examples I do the sorting first and rendering second. This keeps things cleaner and clearer in my opinion.
Example 1
Loop queried posts and sort them into two helper arrays. If those arrays have posts, loop them through and render posts.
$posts = helper_function_to_query_posts();
$future_posts = array();
$past_posts = array();
$today = strtotime('today');
foreach ($posts as $post) {
if ( $post->post_date >= $today ) {
$future_posts[] = $post;
} else {
$past_posts[] = $post;
}
}
if ( $future_posts ) {
esc_html_e( 'Upcoming Posts', 'sage' );
helper_function_to_handle_looping_and_rendering_of_posts( $future_posts );
}
if ( $past_posts ) {
esc_html_e( 'Past Posts', 'sage' );
helper_function_to_handle_looping_and_rendering_of_posts( $past_posts );
}
Example 2
Loop queried posts and push post html into helper variables. Echo those variables afterwards.
$posts = helper_function_to_query_posts();
$future_posts_html = '';
$past_posts_html = '';
$post_html_template = '<div class="my-post">
<h2>%s</h2>
%s
</div>';
$today = strtotime('today');
foreach ($posts as $post) {
if ( $post->post_date >= $today ) {
$future_posts_html .= sprintf(
$post_html_template,
esc_html($post->post_title),
esc_html($post->post_excerpt),
);
} else {
$past_posts[] = .= sprintf(
$post_html_template,
esc_html($post->post_title),
esc_html($post->post_excerpt),
);
}
}
if ( $future_posts_html ) {
esc_html_e( 'Upcoming Posts', 'sage' );
echo $future_posts_html;
}
if ( $past_posts_html ) {
esc_html_e( 'Past Posts', 'sage' );
echo $past_posts_html;
}
