2017.7.14 wordpress 通过条件检索
通过页面ID
<?php $posts = query_posts('page_id=2'); ?>
//query_posts('cat=1,2,3');根据ID显示多个分类
//query_posts('cat=-3');排除某一分类中的文章
//query_posts(array('category__and' => array(1,5)));既是分类ID1，也是分类ID5的文章
//query_posts(array('category__in' => array(1,5)));属于分类ID1或分类ID5的文章
//query_posts(array('category__not_in' => array(1,5)));不属于分类ID1，且不属于分类ID5的文章
<?php while (have_posts()) : the_post(); ?>
<?php global $post; echo $post->post_name; ?>
<?php $category = get_the_category(); echo $category[0]->slug;?>
<?php the_content(); ?>
<?php endwhile;wp_reset_query(); ?>通过页面ID获取文章时间
<div class="notes-date">最終更新日：
<?php $id= 100;
$post_modified = get_post($id)->post_modified;
$d=strtotime($post->post_modified);echo date('Y/m/d',$d);?>
</div>
<div class="notes-date">最終更新日：
<?php $id= 100;
$post_modified = get_post($id)->post_modified;
echo $post_modified;?>
</div>
父级id并获取文章
<?php wp_reset_query();
$categories = get_the_category();
foreach($categories as $category) {
$output = $category->term_id;
}
query_posts('&cat='. $output .'&orderby=date&showposts=4'); ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<?php the_title(); ?>
<?php endwhile; endif; ?>通过分类获取文章
<?php wp_reset_query();query_posts($query_string.'&cat=10&orderby=date&showposts=3') ?>
<?php while ( have_posts() ): the_post();?>
<?php the_content(); ?>
<?php endwhile; wp_reset_query(); ?>自定义文章类型 输出的是分类 指定分类下的子分类(page页面使用)
<?php if ( have_posts() ):?>
<?php
$term_id = 21;
$taxonomy_name = 'commodity-category';
$term_children = get_term_children( $term_id, $taxonomy_name );
if($term_children){
foreach ( $term_children as $child ) {
$term = get_term_by( 'id', $child, $taxonomy_name );
?>
<article>
<a href="<?php echo esc_url( get_term_link( $child, $taxonomy_name ) ); ?>" class="">
<img src="<?php
$large_image_url = z_taxonomy_image_url($child);
if(!empty($large_image_url)){if (function_exists('z_taxonomy_image_url')) echo z_taxonomy_image_url($child);}
else{
echo get_template_directory_uri().'/images/item/cov.png';
} ?>" alt="<?php bloginfo('name');
?>"/><span class="brk"></span><em><?php echo $term->name; ?></em></a>
</article>
<?php
}
}
else {echo 'The term has no children to display.';}
?>
<?php endif; wp_reset_query();?>自定义文章类型获取当前分类的id 然后进行检索 分类下的内容标题
<?php wp_reset_query(); $term = get_queried_object()->term_id;$posts =query_posts('term='.$term.'&post_type=commodity&orderby=date&showposts=-1'); ?>
<?php while ( have_posts() ) : the_post(); ?>
<article>
<div><img src="<?php echo get_template_directory_uri().'/images/item/cov.png';?>" alt="<?php bloginfo('name');?>"/>
<span class="brk"></span><em><?php the_title(); ?></em>
</div>
</article>
<?php endwhile; ?>
