代码::
```
<title>
        <?php if (function_exists('is_tag') && is_tag()) {
        single_tag_title('Tag Archive for &quot;'); echo '&quot; - ';
        } elseif (is_archive()) {
        wp_title(''); echo ' Archive - ';

        } ?>
    </title>
```
插入jquery
===========
```
<?php wp_enqueue_script('jquery');?>
```
Global Custom Fileds
====================
p66
LOOP
=====
```
<?php if(have_post()):while(have_post()):the_post();
endwhile;else:
endif;
?>
```
LOOP ONLY 函数
==============
the_title()
the_permalink()
the_ID()
the_author()
the_category()
$post->ID
$post->post_content
$post->post_modified
$post->post_name return the slug of the post
更多函数请看 digwp.com/u/399
Outside Loop 函数
=================
wp_list_pages()
next_posts_link()
wp_tag_cloud()
get_permalink()
Comments 的逻辑
===============
1.是否文章受保护（需输入密码）
2.是否有评论
3.是否评论开放
4.是否需要登陆
Sidebar
=======
```
<?php get_sidebar();?>
```
<?php get_sidebar('secondary');?> 读取sidebar-secondary.php

    if (have_posts()) : while (have_posts()) : the_post();
    endwhile; else:
    endif;
    wp_reset_query(); // reset the query
?>
```
query_post 会影响is_page()和is_single()的模板标签。
WP_Query
---------
```
<?php // The WordPress Loop - customized with WP_Query
$custom_query = new WP_Query('cat=-9'); // exclude Asides category
