wordpress常用调用标签

调用头部：<?php get_header(); ?>

调用底部：<?php get_footer(); ?>

调用自定义模板文件：<?php get_template_part('list-head'); ?>

路径：<?php bloginfo('template_url'); ?>

缩略图：<?php the_post_thumbnail_url( 'full' ); ?>

调用标题：<?php the_title(); ?>

发布时间：<?php the_time('Y-m-d');?>

文章内容：<?php the_content();?>

面包屑：<?php if (function_exists('cmp_breadcrumbs')) cmp_breadcrumbs(); ?>

分类页面：

调用分类图片：<?php if (function_exists('z_taxonomy_image_url')) echo z_taxonomy_image_url(); ?>

分类目录名称：

<?php $thiscat = get_category($cat);echo $thiscat->name; ?>

菜单调用

在需要显示菜单的位置调用此代码：

<?php wp_nav_menu(array('theme_location' => 'header_menu', 'container' => false,'items_wrap' => '<ul class="nav_ul">%3$s</ul>', 'fallback_cb' => 'Bing_menu_null_fallback')); ?>

在functions.php中添加菜单功能

<?php// 添加菜单功能
function sanyi_setup()
{register_nav_menus(['header_menu' => __('顶部导航'),'footer_menu'  => __('底部导航')]);
}
add_action('after_setup_theme', 'sanyi_setup');?>

首页循环调用指定栏目

<?php
$args = array('cat' => 4,   // 分类ID  'posts_per_page' => 3, // 显示篇数 
);
query_posts($args);
if (have_posts()) : while (have_posts()) : the_post();
?><div class="swiper-slide"><!-- 文章链接 --><a href="<?php the_permalink(); ?>"><div class="over"><!-- 调用文章缩略图 --><img src="<?php the_post_thumbnail_url('full'); ?>" alt="" class="w100"></div><div class="content"><div class="title"><!-- 文章标题 --><?php the_title(); ?></div><div class="txt"><!-- 文章摘要 --><?php if (has_excerpt()) {echo $description = get_the_excerpt(); //文章编辑中的摘要} else {echo mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 170, "……"); //文章编辑中若无摘要，自定截取文章内容字数做为摘要} ?></div><div class="time"><!-- 调用发布日期 --><?php echo date('M');the_time('d,Y'); ?></div></div></a></div>
<?php endwhile;
endif;
wp_reset_query(); ?>

首页调用指定分类的二级分类

<?php
$args = array('include' => '1',
);
$categories = get_categories($args);
foreach ($categories as $category) { ?><?php$argszi = array('child_of' => $category->term_id,'parent' => $category->term_id,'hide_empty' => '0','orderby' => 'ID','order' => 'ASC',);$categorieszi = get_categories($argszi);foreach ($categorieszi as $categoryzi) {?><div class="col-md-2"><a href="<?php echo get_category_link($categoryzi->term_id); ?>"><div class="box"><div class="content"><div class="en_name2"><?php echo $categoryzi->name; ?></div></div></div></a></div><?php }
}
?>

category分类循环调用文章

<?php while (have_posts()) : the_post(); ?><li class="list"><a href="<?php the_permalink(); ?>"><div class="over"><img src="<?php the_post_thumbnail_url('full'); ?>" alt="<?php the_title(); ?>" class="w100"></div><div class="content"><div class="en_name"><?php the_title(); ?></div><!-- 所属分类 --><div class="txt"><?php$category = get_the_category();echo $category[0]->cat_name;?></div></div></a></li>
<?php endwhile; ?><?php while (have_posts()) : the_post(); ?><div class="col-sm-6 col-12"><a href="<?php the_permalink(); ?>"><div class="bord"><div class="over"><img src="<?php the_post_thumbnail_url('full'); ?>" alt="" class="w100"></div><div class="content"><div class="title"><?php the_title(); ?></div><div class="txt"><?php if (has_excerpt()) {echo $description = get_the_excerpt(); //文章编辑中的摘要} else {echo mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 170, "……"); //文章编辑中若无摘要，自定截取文章内容字数做为摘要} ?></div><div class="time"><?php echo date('M');the_time('d,Y'); ?><!-- July 28,2022 --></div></div></div></a></div>
<?php endwhile; ?>

single文章页面调用循环

<div class="list_news"><div class="container"><div class="row"><?php while (have_posts()) : the_post(); ?><div class="col-sm-6 col-12"><a href="<?php the_permalink(); ?>"><div class="bord"><div class="over"><img src="<?php the_post_thumbnail_url('full'); ?>" alt="" class="w100"></div><div class="content"><div class="title"><?php the_title(); ?></div><div class="txt"><?php if (has_excerpt()) {echo $description = get_the_excerpt(); //文章编辑中的摘要} else {echo mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 170, "……"); //文章编辑中若无摘要，自定截取文章内容字数做为摘要} ?></div><div class="time"><?php echo date('M');the_time('d,Y'); ?><!-- July 28,2022 --></div></div></div></a></div><?php endwhile; ?></div><div class="pageinfo"><?php par_pagenavi(9); ?></div></div>
