//加分类页面跳转代码:(子分类也能这样获取)

分页
<div class="container-fluid text-center">
<div class="row">
<div class="col-md-10 col-md-offset-1 col-xs-12 blue_list">
<div class="col-md-12 col-xs-12 col-sm-12">
<?php pagination($query_string); ?>
</div>
</div>
</div>
</div>
//此分页只对当前分类目录下的文章起作用
-----------------------------------------------------------
<?php query_posts('category_name=industry'); //取yewu所有置顶的文章?>
<?php while (have_posts()) : the_post(); ?>
<?php if(is_sticky($id)==true) {?>
<li><a href="<?php echo get_permalink($id); ?>"><?php the_title(); ?><span><?php the_time("Y-m-d"); ?></span></a></li>
<?php }?>
<?php endwhile;?>
<?php wp_reset_query(); ?>
特别注意:在当前分类下就不要用<?php query_posts('category_name=industry');否则分页不起作用
如果当前分类下有多个分类的文章列表,这些分类一定要是当前分类的子分类,不然分页无效
-----------------------------------------------------------
<?php the_post_thumbnail(); ?>//特色图片

获取文章中第一张图片或视频
在function中写函数
//获取第一张图片
function catch_that_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = "http://yourwebsite/default.jpg";
}
return $first_img;
}
或
function catch_the_image( $id ) {
// global $post, $posts;
$first_img = '';
// 如果设置了缩略图
$post_thumbnail_id = get_post_thumbnail_id( $id );
if ( $post_thumbnail_id ) {
$output = wp_get_attachment_image_src( $post_thumbnail_id, 'large' );
$first_img = $output[0];
}
else { // 没有缩略图,查找文章中的第一幅图片
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ // 既没有缩略图,文中也没有图,设置一幅默认的图片
$first_img = "http://yourdomain.tld/images/default.jpg";
}
}
return $first_img;
}//我用了无效
//获取第一个视频
function catch_that_video() {
global $post, $posts;
