Hi @jloupf
I think I found the issue. It seems ‘post_where’ filter won’t work with get_posts() function. To fix it, you need to set suppress_filters option to false. Please take a look at the note on this page: https://codex.wordpress.org/Plugin_API/Filter_Reference/posts_where.
So, your code should be something like this:
$formations = get_posts(array(
'suppress_filters' => FALSE,
'post_type' => 'formation',
'meta_query' => array(
array(
'key' => 'chapitres_%_lecon', // name of custom field
'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
'compare' => 'LIKE'
)
)
));
if( $formations ): ?>
. . .
I hope this helps 🙂
