我一直在尝试为当前父页面的每个子页面显示字幕。目前我已经开始工作,以便显示儿童页面的所有标题。
基本上我希望它在子页面的每个标题下面显示副标题。
// Get childern
$children = ($post->post_parent) ? wp_list_pages('title_li=&child_of='.$post->post_parent.'&echo=0') : wp_list_pages('title_li=&child_of='.$post->ID.'&echo=0');
// Set subtitle
$subtitle = get_the_title($post->the_subtitle);
echo $children;
echo $subtitle;
非常感谢任何帮助。
干杯

您有两种选择:
扩展Walker_page
类以创建用于wp_list_pages()
的自定义迭代器。
将此添加到您的functions.php
:
class Subtitle_walker extends Walker_page {
function start_el(&$output, $page, $depth, $args, $current_page) {
if ( $depth )
$indent = str_repeat("\t", $depth);
else
$indent = '';
extract($args, EXTR_SKIP);
$css_class = array('page_item', 'page-item-'.$page->ID);
if ( !empty($current_page) ) {
$_current_page = get_page( $current_page );
_get_post_ancestors($_current_page);
if ( isset($_current_page->ancestors) && in_array($page->ID, (array) $_current_page->ancestors) )
$css_class[] = 'current_page_ancestor';
if ( $page->ID == $current_page )
$css_class[] = 'current_page_item';
elseif ( $_current_page && $page->ID == $_current_page->post_parent )
$css_class[] = 'current_page_parent';
} elseif ( $page->ID == get_option('page_for_posts') ) {
$css_class[] = 'current_page_parent';
}
$css_class = implode( ' ', apply_filters( 'page_css_class', $css_class, $page, $depth, $args, $current_page ) );
//Added subtitle support
$output .= $indent . '<li class="' . $css_class . '"><a href="' . get_permalink($page->ID) . '">' . $link_before . apply_filters( 'the_title', $page->post_title, $page->ID ) . $link_after . get_the_post_thumbnail($page->ID, array(72,72)) .'</a>'.' <span class="subtitle">'.get_the_subtitle($page->ID,'','',0).'</span>';
if ( !empty($show_date) ) {
if ( 'modified' == $show_date )
$time = $page->post_modified;
else
$time = $page->post_date;
$output .= " " . mysql2date($date_format, $time);
}
}
}
并在模板文件中调用它:
$subtitle_menu = new Subtitle_walker();
$args = array(
'title_li' => '',
'child_of' => ($post->post_parent) ? $post->post_parent : $post->ID,
'echo' => 0,
'walker' => $subtitle_menu
);
$children = wp_list_pages($args);
echo $children;
注意:以前的代码基于this tutorial,您可以阅读它以深入解释它正在做什么
您可以使用get_page_children
查询子页面,然后遍历它们并构建/回显您的自定义列表项:
//Set up the objects needed
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));
//Get children
$children = ($post->post_parent) ? get_page_children( $post->post_parent, $all_wp_pages ) : get_page_children( $post->ID, $all_wp_pages );
//Build custom items
foreach($children as $child){
echo '<li class="page-item">';
echo '<a href="'.get_permalink($child->ID).'">'.get_the_title($child->ID).'</a><br/>';
echo '<span class="subtitle">'.get_the_subtitle($child->ID).'</span>';
echo '</li>';
}
