wordpress主题开发-部分函数调用整理

<?php echo $post->post_content;?>  //文章内容

<?php echo $post->post_title;?>  //标题

<?php echo get_the_author_meta( 'display_name', $post->post_author )?>  //作者

<?php echo get_post_meta($post->ID, '演示地址', true); ?>  //获取自定义字段为“演示地址”的值

<?php echo $post->post_excerpt;?>  //摘要<?php echo $post->post_excerpt;?>  //摘要

<?php $category = get_the_category();if($category[0]){echo get_category_link($category[0]->term_id );}?>  //调用当前文章所属分类的链接,用于返回列表

<?php $cat=get_category_by_slug('news-gs');echo get_category_link($cat->term_id);?>   //指定分类别名,获取该别名分类的链接

<?php echo get_template_directory_uri();?>  //获取主题目录

<?php//指定文章分类,方便调用上一页下一页在同一个分类
$categories = get_the_category();
$categoryIDS = array();
foreach ($categories as $category) {
array_push($categoryIDS, $category->term_id);
}
$categoryIDS = implode(",", $categoryIDS);
?>
<?php if (get_previous_post($categoryIDS)) { previous_post_link('%link','%title',true);} else { echo "已是最后一篇文章";} ?>
<?php if (get_next_post($categoryIDS)) { next_post_link('%link','%title',true);} else { echo "已是最新的文章";} ?>

 

文章的循环输出:

<?php if( have_posts() ) : while( have_posts() ) : the_post(); ?>
循环文章调用
<?php endwhile; ?>

 

文章的分页

<div class="shebei-fanye"><?php wp_pagenavi(); ?></div>
<?php endif; ?>

functions.php代码:

function wp_pagenavi() {
global $wp_query, $wp_rewrite;
//判断当前页面
$wp_query->query_vars['paged'] > 1 ? $current = $wp_query->query_vars['paged'] : $current = 1;

$pagination = array(
'base' => @add_query_arg('paged','%#%'),
'format' => '',
'total' => $wp_query->max_num_pages, //总共显示的页码数
'current' => $current, //当前页码数
'show_all' => false, //是否将所有页码都显示出来,需配合下两个参数
'type' => 'plain',
'end_size'=>'1', //在最后面和最前面至少显示多少个数,
'mid_size'=>'3', //在当前页码的前后至少显示多少个页码数
'prev_text' => '<', //是否显示“上一页”“下一页”链接
'next_text' => '>'
);

if( $wp_rewrite->using_permalinks() )
$pagination['base'] = user_trailingslashit( trailingslashit( remove_query_arg('s',get_pagenum_link(1) ) ) . 'page/%#%/', 'paged');
if( !empty($wp_query->query_vars['s']) )
$pagination['add_args'] = array('s'=>get_query_var('s'));
echo paginate_links($pagination);
}
