没有内容时不显示任何内容
Don't show anything when there is no content
我在搜索结果页面中有以下代码,我希望它在任何部分都没有内容时不显示它。
if ( have_posts() ) {
$types = array('singer', 'music', 'album');
foreach( $types as $type ){
if( $type == 'singer'){
echo ' <h1>Singers</h1> ';
} elseif ( $type == 'music'){
echo '<h1>Musics</h1>';
}
elseif ( $type == 'album'){
echo '<h1>Albums</h1>';
}
while( have_posts() ){
the_post();
if( $type == get_post_type() ){
the_post_thumbnail('medium'); ?>
<h3><a href="<?php echo get_permalink(); ?>">
<?php the_title(); ?>
</a></h3>
<?php
}
}
rewind_posts();
}
} else {
echo us_translate( 'No results found.' );
}
这不是一个好的解决方案,但应该可行)

'singer' => array( 'title' => 'Singers', 'content' => '' ),
'music' => array( 'title' => 'Musics', 'content' => '' ),

if ( have_posts() ) {

$type = get_post_type();
if ( array_key_exists( $type, $types ) ) {
$types[ $type ][ 'content' ] .= get_the_post_thumbnail( null, 'medium' );
$types[ $type ][ 'content' ] .= '<h3><a href="' . get_the_permalink() . '">' . get_the_title() . '</h3>';
}
}
foreach( $types as $k => $v ) {
