@vipstephan This has been of help, thank you. With a little bit of experimentation I’ve been able to successfuly do a query based on a sub field that is a basic text field value but all attempts at doing the same for a custom taxonomy – which I was hoping to do – have so far failed.
In my updated code below the taxonomy is ‘availability’ and the taxonomy name I’m aiming to filter to in this case is ‘windows’.
In functions:
function my_posts_where( $where ) {
$where = str_replace("meta_key = 'colour_swatch_$", "meta_key LIKE 'colour_swatch_%", $where);
return $where;
}
add_filter('posts_where', 'my_posts_where');
and on my template:
<?php
$args = array(
'post_type' => 'colourswatch',
'meta_query' => array(
array(
'key' => 'colour_swatch_$_availability',
'value' => 'windows',
'compare' => 'LIKE'
)
)
);
$query = new WP_Query( $args );
if ( $query->have_posts() ) :
?>
<div class="container container--narrow swatches">
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
<div class="swatches__material">
<h3 class="swatches__title"><?php the_title(); ?></h3>
<?php if( have_rows( 'colour_swatch' ) ): ?>
<ul class="swatches__colours">
<?php while ( have_rows( 'colour_swatch' ) ) : the_row(); ?>
<li class="swatches__swatch">
<div class="swatches__colour" style="background:<?php the_sub_field( 'colour' ); ?>"></div>
<h4 class="swatches__name"><?php the_sub_field( 'colour_name' ); ?></h4>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
</div>
<?php endwhile; wp_reset_postdata(); ?>
</div>
<?php endif; ?>
What am I missing?
