Ummm something doesn’t go well. Here is my code:
/* When a ACF "Featured article" (in 71% articles) is set to true, all the rest are updated to false */
/* First you would have to add acf/save_post action to you function.php so the action runs every time a post is saved or udpated run before ACF saves the $_POST['fields'] data */
add_action('acf/save_post', 'my_acf_save_post', 1);
function my_acf_save_post( $post_id ){
$fields = false;
$fieldId = 'field_5343d06c3e9dc';
$catId = 27;
/* Here I added a if statement so the code runs only for a defined category */
if ( in_category( $catId, $post_id ) ) {
// Check if Fields have been posted
if ( isset( $_POST['fields'] ) ) {
// Store the true/false field on a variable (change the "Field_xxx" id by yours)
$featuredArticle = $fields[$fieldId];
// Check if the true/false field is true
if ( $featuredArticle ) {
/* If it's set to true do a WP_query so you can get the other post that have $featuredArticle set to true here you may want to change the 'cat' to whatever your is (or to all) in the meta query you should use your true/false field name as a key */
$args = array(
'cat' => $catId,
'meta_query' => array(
array(
'key' => 'featured_article',
'value' => '1',
'compare' => '=='
)
)
);
$post_query = new WP_Query( $args );
/* Here we check if the query returns post (if it does it will return featured posts) */
if ( $post_query->have_posts() ) {
while ( $post_query->have_posts() ) {
$post_query->the_post();
/* For each posts we update the true/false field and set it to false */
update_field( $fieldId, false, get_the_ID() );
}
}
}
}
}
} // end my_acf_save_post
