Comparing Checkbox Field to Current Date within Loop - php

Question

I have my checkbox custom field (show_days) as values (1-7) to represent (Moo-Sun) and I tested it with an echo and it is returning the correct value. Example today is Tuesday and the echo is showing 2.
I am trying to compare it to the current date strftime("%u", time()); to only show posts that have the current day check marked. Its not working and Im wondering if I need to add an in_array somewhere. Thanks for your help.
<?php
$days = get_field('show_days');
$date = strftime("%u", time());
if ($query->have_posts() && $days = $date ) { while( $query->have_posts() ) {
$query->the_post();
echo '<div class="onAir"><h3>Currently On Air: ';
the_title();
echo $days. '</h3></div>';
} wp_reset_postdata();
}
?>

Answer 1

You need to add the comparison ($days = $date) as a meta_query to the WP_Query arguments.
<?php
$datetime = date('Y-m-d');
$day_number = date('w', strtotime($datetime));
$args = array(
'post_type' => 'your_post_type',
'meta_key' => 'show_days',
'meta_value' => $day_number,
'meta_compare' => '=',
);
$query = new WP_Query( $args );
?>
<?php if ( $the_query->have_posts() ) : ?>
<!-- the loop -->
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<div class="onAir">
<h3>Currently On Air: <?php the_title(); ?> <?php echo $day_number; ?></h3>
</div>
<?php endwhile; ?>
<!-- end of the loop -->
<?php wp_reset_postdata(); ?>
<?php endif; ?>

Alrighty...after a lot of different comparisons and pulling out of my hair, I got it sorted it out. Comparing two custom field time ranges with the current time, and then comparing the selected day of the week with the current day and WP Query the posts and on top of that....my Wordpress timestamp was 6 hours ahead. Ugh! haha, This code did it
<?php
$time = current_time('H:i:s');
date_default_timezone_set('America/Denver');
$date = strftime("%A", time());
$shows = get_field('station_shows', false, false);
$query = new WP_Query ( array(
'post_type' => 'shows',
'posts_per_page' => 1,
'post__in' => $shows,
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'start_time',
'value' => $time,
'compare' => '<=',
'type' => 'TIME',
),
array(
'value' => $time,
'key' => 'end_time',
'compare' => '>=',
'type' => 'TIME',
),
'relation' => 'AND',
array(
'key' => 'show_days',
'value' => $date,
'compare' => 'LIKE',
)
)));
if ($query->have_posts() ) { while( $query->have_posts() ) {
$query->the_post();
echo '<div class="onAir"><h3>Currently <span>On Air</span> : ';
the_title();
echo '</h3></div>';
}
wp_reset_postdata();
}
?>
