学习typecho主题开发笔记01，typecho主题笔记01

博客被加速乐坑掉,于是有了学习typecho主题开发的想法,感谢这个机会!


首先是去看主题文件夹下面的'index.php',一个博客的文章页面一般包括下面几个基本元素

• 作者
• 发表时间
• 文章分类 1 php 2 /** 3 * 这是 Typecho 0.9 系统的一套默认皮肤 4 * 5 * @package Typecho Replica Theme 6 * @author Typecho Team 7 * @version 1.2 8 * @link http://typecho.org 9 */ 10 11 if (!defined('__TYPECHO_ROOT_DIR__')) exit; 12 $this->need('header.php'); 13 ?> 14 15
  class="col-mb-12 col-8" id="main" role="main"> 16 while($this->next()): ?> 17

  class="post" itemscope itemtype="http://schema.org/BlogPosting"> 18

  class="post-title" itemprop="name headline">$this->title() ?>

  19

  class="post-meta"> 20
  • $this->author(); ?>
  21
  • time datetime="$this->date('c'); ?>" itemprop="datePublished">$this->date('F j, Y'); ?>time>
  22
  • $this->category(','); ?>
  23
  • $this->commentsNum('评论', '1 条评论', '%d 条评论'); ?>
  24

  25

  class="post-content" itemprop="articleBody"> 26 $this->content('- 阅读剩余部分 -'); ?> 27

  28

  29 endwhile; ?> 30 31 $this->pageNav('« 前一页', '后一页 »'); ?> 32
  33 34 $this->need('sidebar.php'); ?> 35 $this->need('footer.php'); ?

下面是这是index.php的源代码:

<span> 1</span> <?<span>php
</span><span> 2</span> <span>/*</span><span>*
</span><span> 3</span> <span> * 这是 Typecho 0.9 系统的一套默认皮肤
</span><span> 4</span> <span> * 
</span><span> 5</span> <span> * @package Typecho Replica Theme 
</span><span> 6</span> <span> * @author Typecho Team
</span><span> 7</span> <span> * @version 1.2
</span><span> 8</span> <span> * @link http://typecho.org
</span><span> 9</span>  <span>*/</span>
<span>10</span> 
<span>11</span> <span>if</span> (!<span>defined</span>('__TYPECHO_ROOT_DIR__')) <span>exit</span><span>;
</span><span>12</span>  <span>$this</span>->need('header.php'<span>);
</span><span>13</span>  ?>
<span>14</span> 
<span>15</span> <div <span>class</span>="col-mb-12 col-8" id="main" role="main">
<span>16</span>     <?php <span>while</span>(<span>$this</span>-><span>next</span>()): ?>
<span>17</span>         <article <span>class</span>="post" itemscope itemtype="http://schema.org/BlogPosting">
<span>18</span>             <h2 id="class-span-post-title-itemprop-name-headline-a-itemtype-url-href-php-span-this-span-permalink-php-span-this-span-title-a">class</span>="post-title" itemprop="name headline"><a itemtype="url" href="<?php <span>$this</span>->permalink() ?>"><?php <span>$this</span>->title() ?></a></h2>
<span>19</span>             <ul <span>class</span>="post-meta">
<span>20</span>                 <li itemprop="author" itemscope itemtype="http://schema.org/Person"><?php _e('作者: '); ?><a itemprop="name" href="<?php <span>$this</span>->author->permalink(); ?>" rel="author"><?php <span>$this</span>->author(); ?></a></li>
<span>21</span>                 <li><?php _e('时间: '); ?><<span>time</span> datetime="<?php <span>$this</span>->date('c'); ?>" itemprop="datePublished"><?php <span>$this</span>-><span>date</span>('F j, Y'); ?></<span>time</span>></li>
<span>22</span>                 <li><?php _e('分类: '); ?><?php <span>$this</span>->category(','); ?></li>
<span>23</span>                 <li itemprop="interactionCount"><a itemprop="discussionUrl" href="<?php <span>$this</span>->permalink() ?>#comments"><?php <span>$this</span>->commentsNum('评论', '1 条评论', '%d 条评论'); ?></a></li>
<span>24</span>             </ul>
<span>25</span>             <div <span>class</span>="post-content" itemprop="articleBody">
<span>26</span>                 <?php <span>$this</span>->content('- 阅读剩余部分 -'); ?>
<span>27</span>             </div>
<span>28</span>         </article>
<span>29</span>     <?php <span>endwhile</span>; ?>
<span>30</span> 
<span>31</span>     <?php <span>$this</span>->pageNav('&laquo; 前一页', '后一页 &raquo;'); ?>
<span>32</span> </div><!-- <span>end</span> <span>#</span><span>main--></span>
<span>33</span> 
<span>34</span> <?php <span>$this</span>->need('sidebar.php'); ?>
<span>35</span> <?php <span>$this</span>->need('footer.php'); ?>

<p>2-9行是注释,里面包含了主题的各种信息,每行以*开头。</p>

@package 表示主题的名称

@author 表示作者信息

@version 表示主题当前的版本

@link 表示作者的网站链接

include()方法用来包含要用到的php文件,具体用法查阅PHP官方手册include()方法

在12,34,35行都能看到$this->need()，它在typecho里面就和include()的作用是一样的

<span>$this</span>->need('header.php'<span>);
</span><?php <span>$this</span>->need('sidebar.php'); ?>
<?php <span>$this</span>->need('footer.php'); ?>

所以上面的代码就是调用header.php,sidebar.php,footer.php。具体这三个php文件是什么作用的,很简单,顾名思义哦!

然后就是文章页面的主体了

 <div <span>class</span>="col-mb-12 col-8" id="main" role="main">
     <?php <span>while</span>(<span>$this</span>-><span>next</span>()): ?>
         <article <span>class</span>="post" itemscope itemtype="http://schema.org/BlogPosting">
             <h2 id="class-span-post-title-itemprop-name-headline-a-itemtype-url-href-php-span-this-span-permalink-php-span-this-span-title-a">class</span>="post-title" itemprop="name headline"><a itemtype="url" href="<?php <span>$this</span>->permalink() ?>"><?php <span>$this</span>->title() ?></a></h2>
             <ul <span>class</span>="post-meta">
                 <li itemprop="author" itemscope itemtype="http://schema.org/Person"><?php _e('作者: '); ?><a itemprop="name" href="<?php <span>$this</span>->author->permalink(); ?>" rel="author"><?php <span>$this</span>->author(); ?></a></li>
                 <li><?php _e('时间: '); ?><<span>time</span> datetime="<?php <span>$this</span>->date('c'); ?>" itemprop="datePublished"><?php <span>$this</span>-><span>date</span>('F j, Y'); ?></<span>time</span>></li>
                 <li><?php _e('分类: '); ?><?php <span>$this</span>->category(','); ?></li>
                 <li itemprop="interactionCount"><a itemprop="discussionUrl" href="<?php <span>$this</span>->permalink() ?>#comments"><?php <span>$this</span>->commentsNum('评论', '1 条评论', '%d 条评论'); ?></a></li>
             </ul>
             <div <span>class</span>="post-content" itemprop="articleBody">
                 <?php <span>$this</span>->content('- 阅读剩余部分 -'); ?>
             </div>
         </article>
     <?php <span>endwhile</span>; ?>
 
     <?php <span>$this</span>->pageNav('&laquo; 前一页', '后一页 &raquo;'); ?>
</div><!-- <span>end</span> <span>#</span><span>main--></span>

endwhile是什么鬼????为什么我重来没用过....查阅了下资料,原来是一种语法糖:)

文章主体就是从这里开始到结束的

<?php <span>while</span>(<span>$this</span>-><span>next</span>()): ?>
<?php <span>endwhile</span>; ?>

:替代了{

;替代了}

详细见文章:PHP中流程控制的替代语法

接着就是一些方法了

<?php <span>$this</span>->permalink() ?><span>     文章所在的连接
</span><?php <span>$this</span>->title() ?><span>     文章标题
</span><?php <span>$this</span>->author(); ?><span>     文章作者
</span><?php <span>$this</span>->author->permalink(); ?><span>     文章作者地址
</span><?php <span>$this</span>-><span>date</span>('F j, Y'); ?><span>     文章的发布日期，格式可参考PHP日期格式
</span><?php <span>$this</span>->category(','); ?><span>     文章所在分类
</span><?php <span>$this</span>->commentsNum('%d Comments'); ?><span>     文章评论数及连接
</span><?php <span>$this</span>->content('Continue Reading...'); ?>     文章内容，其中的&ldquo;<span>Continue</span> Reading&hellip;&rdquo; 是显示摘要时隐藏部分的文字

_e()这是什么方法,专一而精十

看了下wordpress里面的_e()方法,居然是用作翻译的。。。难道typecho还有歪果仁使用(逃

直接打印输出到 html 中的字符串，就用 _e() 。具体看这里

在代码里面还能看见itemprop属性,这是html5新加的,暂时不用管他Q.Q

最后是一个分页的方法

<?php <span>$this</span>->pageNav(); ?>

 

 

至此,index.php文件已经被分析一遍了,虽然我没有php基础,但是学习了之后发现不难,嘿嘿!继续努力!
