Hello! I’m new to ACF and PHP / WordPress. I’m trying to get a checkbox value shown on my wordpress site, but I’m getting the error message “in_array() expects parameter 2 to be array..”
This is my code:
`<?php if(have_posts()) : ?>
<?php while(have_posts()) : the_post(); ?>
<?php
$current_date =””;
$count_posts = wp_count_posts();
$nextpost = 0;
$published_posts = $count_posts->publish;
$myposts = get_posts(array(‘posts_per_page’=>$published_posts));
foreach($myposts as $post) :
$nextpost++;
setup_postdata($post);
$date = get_the_date(“F Y”);
if($current_date!=$date):
if($nextpost>1): ?>
<?php endif; ?>
<?php endif; ?>
“>
<img class=”all <?php $selected = get_field(‘type’);
if( in_array(‘web’, $selected) ) {
echo ‘web’;
} ?>” />
<?php endforeach; wp_reset_postdata(); ?>
<?php endwhile; ?>
<?php endif; ?>
Hi @unmatched
It’s possible that the “type” field doesn’t have value, so get_field() will returns an empty string while in_array() needs an array for the second parameter, not an empty string.
I think you can check if it has a value or not first like this:
$selected = get_field('type');
if($selected){
if( in_array('web', $selected) ) {
echo 'web';
}
}
I hope this helps.
