我以前也做过类似的工作,用于词汇表页面。我的代码如下。希望你能由此推断。注意,I’;m正在使用WP_Query
不query_posts
, 因为这是最佳实践。
<?php
$args = array(
\'post_type\' => \'my_glossary_term\',
\'orderby\' => \'title\',
\'order\' => \'ASC\',
\'posts_per_page\' => -1
);
$query = new WP_Query( $args );
$dl = \'\';
$glossary_letter = \'\';
$active_letters = array( );
while ( $query->have_posts() ) {
$query->next_post();
$term_letter = strtoupper( substr( $query->post->post_title, 0, 1 ) );
if ( $glossary_letter != $term_letter ) {
$dl .= (count( $active_letters ) ? \'</dl>\' : \'\') . \'<li id="\' . $term_letter . \'"><span class="subheading">\' . $term_letter . \'</span><dl>\';
$glossary_letter = $term_letter;
$active_letters[] = $term_letter;
}
$dl .= \'<dt>\' . $query->post->post_title . \'</dt>\';
$dl .= \'<dd>\' . $query->post->post_content . \'</dd>\';
}
$dl .= \'</dl></li>\';
$ul = \'<ul class="letters">\';
foreach ( array( \'A\', \'B\', \'C\', \'D\', \'E\', \'F\', \'G\', \'H\', \'I\', \'J\', \'K\', \'L\', \'M\', \'N\', \'O\', \'P\', \'Q\', \'R\', \'S\', \'T\', \'U\', \'V\', \'W\', \'X\', \'Y\', \'Z\' ) as $letter ) {
$ul .= \'<li>\' . (in_array( $letter, $active_letters ) ? \'<a href="#\' . $letter . \'">\' . $letter . \'</a>\' : $letter) . \'</li>\';
}
$ul .= \'</ul>\';
echo \'<div id="glossary">\' . $ul . \'<ul class="definitions">\' . $dl . \'</ul></div>\';
?>
