Can't change posts per page in WordPress Post Type Query

Question

I have a custom post type called "Events". The post displays fine, except that the WP Query loop only displays one post instead of all of them. Here is the complete code from my functions.php file for Events:

    function min_get_events ( $echo = true ) {
     $events = new WP_query(array(
    'post_type' => 'events',
    'posts_per_page' => -1,
    'order' => 'ASC',
    'orderby' => 'meta_value',
    'meta_key' => 'min_event-start',
    'meta_query' => array(
        'key'     => 'min_event-start',
        'value'   => date('Y-m-d'),
        'compare' => '>',
    )
));

$i = 0;
$n = 1;

if ( $events->have_posts() ) :
    while ( $events->have_posts() ):
        global $post;
        $events->the_post();

        $open_date = get_post_meta($post->ID, 'min_event-start', true);
        $close_date = get_post_meta($post->ID, 'min_event-end', true);
        $start = strtotime($open_date);
        $end = strtotime($close_date);
        if ($start==$end || $start > $end) {
            $date_string = date('F j, Y', $start);
        }
        else {
            $date_string = date('F j, Y', $start) .' – '. date('F j, Y', $end);
        }
        //$description = get_post_meta($post->ID, 'event-description', true);
        $location = get_post_meta($post->ID, 'min_event-location', true);
        $url = get_post_meta($post->ID, 'min_event-url', true);
        //$registration_url = get_post_meta($post->ID, 'event-registration-url', true);
        $cta_text = get_post_meta($post->ID, 'min_event-cta-text', true);
        $cta = !empty($cta_text) ? $cta_text : 'Register Now';

        $i++;
        if ( $i == 1 ) {
            ?>
            <div class="row">
            <?php
        }
        ?>
        <div class="event col-sm-4">
            <a href="<?= $url ?>">
                <?php the_post_thumbnail('thumb-events'); ?>
            </a>
            <h1><?= htmlentities($post->post_title) ?></h1>
            <div >
                <div><?= $date_string; ?></div>
                <div><?= htmlentities($location) ?></div>
                <div><a href="<?=$url;?>" class="register-now"><?= $cta; ?></a></div>
            </div>
            <!-- <p><?= $description ?></p> -->
            <!-- <p><a href="<?=$url;?>" class="register-now"><?= $cta; ?></a></p> -->
        </div> <!-- .event -->
        <?php


        if ( $i == 3  || ($events->current_post +1) == $events->post_count) {
            ?>
            </div> <!-- <?php echo $i; ?> .row <?php echo $n; ?> -->
            <?php
            $i = 0;
            $n++;
        }

    endwhile;
endif;

ob_start();
?>

<?php
$return = ob_get_contents();
ob_end_clean();
wp_reset_postdata();
if ( $echo ) {
    echo $return;
} else {
    return $return;
}
 }

Am I missing something here?

Answer 1

The meta_query parameter must be change in an array of array for a single custom field handling:

 'meta_query' => array(
     array(
         'key'     => 'min_event-start',
         'value'   => date('Y-m-d'),
         'compare' => '>',
    )
 )

You will the informations WP_Query in the Single Custom field handling part

Hope it will work with this.
