Dieser Thread wurde gelöst. Hier ist eine Beschreibung des Problems und der Lösung.
Problem: I would like to create a custom shortcode that finds all the "person" posts where the author is the current logged-in User, and filter those posts by two custom fields. One of the fields must equal "Yes" and the other field is either blank or does not exist.
Solution: Use an associative array meta query to query by two custom fields:
/* Check if cash gift has any messages */
function cash_gift_message_func( $atts ){
global $current_user;
wp_get_current_user();
$all_posts = get_posts(
array(
'numberposts' => -1,
'author' => $current_user->ID,
'post_type' => 'person',
'meta_query' => array(
'relation' => 'AND',
'message_clause' => array(
'relation' => 'OR',
array(
'key' => 'wpcf-message-for-recipient',
'compare' => '!=',
'value' => ''
),
array(
'key' => 'wpcf-message-for-recipient',
'compare' => 'NOT EXISTS'
)
),
'gift_clause' => array(
'key' => 'wpcf-cash-gift',
'compare' => '=',
'value' => 'Yes'
)
)
)
);
$exec_number = count($all_posts);
return $exec_number;
}
add_shortcode( 'cash_message_func', 'cash_gift_message_func' );
