Hi, i have a doubt
I have a post type called “playlists”, a select field called “categorias”
I want to show playlists posts if the “categorias” value is the same as the current post
I tried this code but filter by value did not work
<?php
$categoria = get_field( "categorias" );
// args
$args = array(
'numberposts' => -1,
'post_type' => 'playlists',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'categorias',
'value' => $categoria,
'compare' => 'LIKE'
)
)
);
// query
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<ul>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li>
<a href="<?php the_permalink(); ?>">
<img src="<?php the_post_thumbnail('thumbnail'); ?>" />
</a>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
<?php wp_reset_query(); // Restore global post data stomped by the_post(). ?>
Not sure if this is best practice, but it seems to me that it would work to simply query post_type = playlists, as you are doing, but without the meta_query. Instead, inside the loop, include:
$currentCat = get_field('categorias', $current_id);
if (get_field('categorias') == $currentCat) {...}
where the $current_id is captured outside the loop.
Hi, Kaitlyn
thanks, but I’m not know what’s still wrong
<?php
if ( is_singular( 'playlists' ) ):
if( have_posts() ): ?>
<ul>
<?php while ( have_posts() ) : the_post();
$current_id = get_the_ID();
$currentCat = get_field('categorias', $current_id);
if (get_field('categorias') == $currentCat): ?>
<li>
<a href="<?php the_permalink(); ?>">
<img src="<?php the_post_thumbnail('thumbnail'); ?>" />
</a>
</li>
<?php endif; ?>
<?php endwhile; ?>
</ul>
<?php endif; // have_post ?>
<?php endif; //is_singular ?>
You need to capture the current ID outside of the loop, otherwise get_the_id() will grab the ID of the post it is currently querying.
Try moving that chunk of code before the while, e.g.:
<?php
if ( is_singular( 'playlists' ) ):
$current_category = get_field( 'categorias', get_the_ID() );
if ( have_posts() ):
?>
Sorry, I try this, but still not work.
<?php
if ( is_singular( 'playlists' ) ):
$current_category = get_field( 'categorias', get_the_ID() );
if( have_posts() ): ?>
<ul>
<?php while ( have_posts() ) : the_post();
if (get_field('categorias') == $current_category): ?>
<li>
<a href="<?php the_permalink(); ?>">
<img src="<?php the_post_thumbnail('thumbnail'); ?>" />
</a>
</li>
<?php endif; ?>
<?php endwhile; ?>
</ul>
<?php endif; // have_post ?>
<?php endif; //is_singular ?>
Is “categorias” a select field or a taxonomy field?
Does the field allow only one selection or multiple selections?
Hi, John
It’ s a select field allowing multiple selections
Select fields are saved as serialized arrays. That means that this
$categoria = get_field( "categorias" );
will return an array and you want to search for other posts that contain one of the values in the array. What you need is something like this
$categoria = get_field( "categorias" );
$meta_query = array('relation' => 'OR');
if ($categoria) {
foreach ($categoria as $value) {
$meta_query[] = array(
'key' => 'categorias',
'value' => '"'.$value.'"',
'compare' => 'LIKE'
);
}
}
// args
$args = array(
'numberposts' => -1,
'post_type' => 'playlists',
'meta_query' => $meta_query
);
