I think you need to check your code.
For example:
<img src="<?php echo wp_get_attachment_url(get_field('film_poster')); ?>" alt="<?php the_title() ?>" title="<?php the_title() ?>" />
If you check the docs for wp_get_attachment_url()
You will see it accepts an attachment ID but your ACF field is returning:
Uses “Image URL” Return Format
So this may explain why the images don’t work
Checking your ‘results’ page, if you view the source, you can see:
<section>
<div id="search-filmgenre">
</div>
</section>
Looking at your code:
<section>
<div id="search-filmgenre">
<?php
// Load field settings and values.
$field = get_field_object('film_genre');
$filmGenres = $field['choices'];
// Display labels.
if ($filmGenres) : ?>
<ul>
<?php foreach ($filmGenres as $value => $label) : ?>
<li><input type="checkbox" value="<?php echo $value; ?>" <?php if (in_array($value, $filmGenres)) : ?> unchecked <?php endif; ?> /><?php echo $label; ?> </li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
</div>
</section>
My thought is due to the URL, the code doesn’t trigger:
$field = get_field_object('film_genre');
So where have you assigned that ACF field to?
