Im using ACF and trying to show a post type title based on the current time. So I have my post type entry with start_time and end_time and my conditional is showing my div.onAir, but Im getting this Recoverable Fatal Error. Here is my code:

<?php
    $time_now = date("g:i a");
    $shows = get_posts( array(
      'post_type' => 'shows',
      'meta_query' => array(
        array(
          'key' => 'start_time',
          'compare' => '<=',
          'value' => $time_now,
          'type' => 'DATETIME',
        ),
        array(
          'key' => 'end_time',
          'compare' => '<=',
          'value' => $time_now,
          'type' => 'DATETIME',
        )
      ),
    ));
  if( $shows ) {
    foreach( $shows as $show ){ ?>
       <div class="onAir">
         Currently On Air: <?php echo the_title($show); ?>
       </div>
  <?php
  wp_reset_query();
}
} ?>

I feel Im close, but I haven't seen this particular error before. Any help would be appreciated! Thanks.

UPDATE:

Tom changed my code up to use WP_Query. I had an issue with the timestamps in ACF and WP matching up. Once I figured that out, this code renders the correct comparison of show posts that I was going for. Please note that I used date_i18n('g:i a'); which fixed my localization timestamp. Thanks Tom and Yuri!

<?php

$time = date_i18n('g:i a');
$shows = get_field('station_shows', false, false);
$query = new WP_Query(array(
  'post_type'       => 'shows',
  'posts_per_page'  => 1,
  'post__in'            => $shows,
  'meta_query' => array(
    'relation' => 'AND',
      array(
          'key'     => 'start_time',
          'compare' => '<=',
          'value'   =>  date_i18n('g:i a', $time),
          'type'    => 'TIME',
      ),
      array(
          'key'     => 'end_time',
          'compare' => '>=',
          'value'   => date_i18n('g:i a', $time),
          'type'    => 'TIME',
      )
  ),
 ) );
 if ( $query->have_posts() ) { while( $query->have_posts() ) { 
 $query-   >the_post();

 echo '<div class="onAir"><h3>Currently On Air @ ';
 the_title();
 if (get_field('dj', $query->ID)) {
           $dj = get_field('dj');
           echo ' w/ ';
        echo $dj;
    }
     echo '</h3></div>';

• Note that you should set suppress_filters to false when using get_posts to avoid the performance hit, otherwise using WP_Query is always better. Also, wp_reset_query shouldn't be used here, it's for cleanup after query_posts – Tom J Nowell ♦ Commented Apr 3, 2020 at 21:25
• Thanks Tom, yes I changed it to new WP_Query and the error changed to Object of class WP_Tax_Query – EdgarAlexPoe Commented Apr 3, 2020 at 21:27
• 1 It sounds like you kept the foreach the same – Tom J Nowell ♦ Commented Apr 3, 2020 at 21:31

the_title doesn't work that way:

the_title( $before, $after, $echo );

$before is the text that comes before the title, but you didn't give it a string/text, you gave it a post object. Post objects aren't strings, PHP doesn't know what to do so it stops and prints an error instead.

For the_title to work, you need to setup the current postdata. Normally a standard loop does this by calling the_post on the query, but you've chosen to use get_posts instead.

This is what a standard post WP_Query post loop should look like:

$query = new WP_Query([ ... ]);
if ( $query->have_posts() ) {
    while( $query->have_posts() ) {
        $query->the_post();
        //.... display post here
    }
    wp_reset_postdata();
}

You are calling WordPress functions incorrectly. I fixed, try this code.

<?php
    $time_now = date( "g:i a" );
    $shows    = get_posts( array(
        'post_type'  => 'shows',
        'meta_query' => array(
            array(
                'key'     => 'start_time',
                'compare' => '<=',
                'value'   => $time_now,
                'type'    => 'DATETIME',
            ),
            array(
                'key'     => 'end_time',
                'compare' => '<=',
                'value'   => $time_now,
                'type'    => 'DATETIME',
            )
        ),
    ) );

    if ( $shows ) :
        foreach ( $shows as $show ) :
    ?>

    <div class="onAir">
        Currently On Air: <?php echo get_the_title($show->ID); ?>
    </div>

    <?php
        endforeach;
        wp_reset_postdata();
    endif;
?>
