I solved it. Maybe it could be a better code. But it works and i’m happy with it. 🙂
<?php
$posts = get_posts(array('meta_key' => 'haus'));
if( $posts ) {
$anzhaus = array();
foreach( $posts as $post ) {
setup_postdata( $post );
$anzhaus[] = get_field('haus');
}; //foreach( $posts as $post )
$uniquehaus = array_unique($anzhaus);
foreach( $uniquehaus as $hpost ) {
setup_postdata( $hpost );
echo('<div class="hausbox"><div class="Haustitel">'.$hpost.'</div>');
$args = array('meta_query' => array('relation' => 'AND', array('key' => 'geschoss'), array('value' => $hpost) ));
$the_query = new WP_Query( $args );
if( $the_query->have_posts() ) {
$anzgeschoss = array();
while ( $the_query->have_posts() ) {
$the_query->the_post();
$anzgeschoss[] = get_field('geschoss');
};
$uniquegeschoss = array_unique($anzgeschoss);
foreach ($uniquegeschoss as $geschoss) {
echo'<div class="geschossbox"><div class="Geschosstitel">'.$geschoss.'</div>';
$wohnargs = array('meta_query' => array('relation' => 'AND', array('value' => $geschoss), array('value' => $hpost) ));
$wohn_query = new WP_Query( $wohnargs );
if( $wohn_query->have_posts() ) {
while( $wohn_query->have_posts() ) {
$wohn_query->the_post(); ?>
<div class="Wohnungsbox"> //here we go!!!
</div>
<?php };
}; ?>
</div>
<?php };
};
wp_reset_query(); // Restore global post data stomped by the_post().
echo('</div>'); //hausbox
} //foreach( $uniquehaus as $hpost )
}; //if( $posts )
wp_reset_query(); // Restore global post data stomped by the_post().
?>
