WordPress: Post Meta Data Section：修订间差异

2008年4月14日 (一) 16:48的版本

The post meta data is the "administrative" information you provide to viewers about

each post. This information usually includes the author of the

post, when it was written (or posted), and how the author

categorized that particular post. This lesson will show you

some different ways to change your Theme design to display these important pieces of

information in the manner you desire.

文章 meta数据是提供给访问者的每个文章的"管理的"信息。这个

信息通常包括作者、写(或是发布)的时间和作者如何分类这篇文章。

这一课将告诉你一些改变主题设计，使用你想要的方法来显示这些重要信息的方法。

In many cases, the post meta data is positioned immediately following the post itself,

though some Themes are designed to place this information at the top of the post, other

designs feature the post meta data in the top or bottom of the sidebar, and some designs

even place the information in the footer. Essentially, post meta data can be styled in

many different ways and with a variety of details.

在很多情况下，文章 meta数据会在文章自身形成后立即形成，一些主题设计成把这些信息放在文章

顶部，别的一些主题可能会放在顶部或者底部的边栏中，还有一写主题甚至设计成放在页脚。如果需要的话文章 meta数据可以设计成不同的方式，带有不同的多种细节内容。

Default Usage

The default WordPress Theme places the post meta data basic

information and tags below the post in a box, before the comments. A condensed version of

the code looks like this:

<small>This entry was posted on 
<?php the_time('l, F jS, Y') ?> at 
<?php the_time() ?> and is filed 
under <?php the_category(', ') ?>. You 
can follow any responses to this entry 
through the <?php comments_rss_link('RSS 2.0'); ?> 
feed.</small>

默认用法

默认的WordPress 主题把文章 meta数据这基本信息和标签定位在文章下部分，在评论之前的一个信息框中。简化的代码如下：

<small>This entry was posted on 
<?php the_time('l, F jS, Y') ?> at 
<?php the_time() ?> and is filed 
under <?php the_category(', ') ?>. You 
can follow any responses to this entry 
through the <?php comments_rss_link('RSS 2.0'); ?> 
feed.</small>

The output result looks like this:

This

entry was posted on Monday, February 12, 2003 at 11:32 and is filed under

[[WordPress:#Default Usage|WordPress Lessons]], [[WordPress:#Default Usage|Things to Know]].

You can follow any responses to this entry though the [[WordPress:#Default Usage|RSS 2.0]]

feed.

这输出结果如下：

This

entry was posted on Monday, February 12, 2003 at 11:32 and is filed under

[[WordPress:#Default Usage|WordPress Lessons]], [[WordPress:#Default Usage|Things to Know]].

You can follow any responses to this entry though the [[WordPress:#Default Usage|RSS 2.0]]

feed.

There are three template tags used in the post meta data.

One, the_time(), is used twice with different

results. The other two tags get the information about the categories and the link to the

RSS feed from the database.

在文章 meta数据中有3种模板标签可以使用，第一，

the_time()，使用两次带有不同的结果，另外两种标签是

得到关于分类的信息和从数据库到RSS feed的连接。

The template tag for the_time() can be set up with a variety of parameters to tell

the time and date of the post from information drawn from the database. In the first usage,

the parameters l, F jS, Y pull the post's date into a format that gives the

weekday, month, date, and year. In the second usage, there are no parameters,

therefore it just returns the time when the post was saved. You will experiment with these

below in [[WordPress:#Changing the Time and Date|Changing the Time and Date]].

the_time()的模板标签有很多显示数据库中的文章时间和日期的参数可以设置。第一种用法，

l, F jS, Y参数，把文章的日期设置成一个周日, 月, 日, and 年的格式，第二种用

法，没有任何参数，这样它只是返回文章是什么时候保存的值。你在下面的[[WordPress:#Changing the

Time and Date|更改时间和日期]]中就会体会到。

The template tag the_category() displays

the categories that the post belongs to. This template tag

can be modified to feature different text, graphics and symbols between the graphics, and

may even use a plugin to display graphics in place of the words. There are many ways to

style these. In this example, the categories are listed with

a comma to separate them.

模板标签the_category()显示文章所属的

分类。这个模板标签可以更改来适应不同的文本、图片、图片之间的

符号，还可以使用插件来代替文字显示图片。有很多种设计方法。在这个例子中列出的

分类使用逗号分开它们。

The last tag is the comments_rss_link()

which uses the parameter RSS 2.0 to identify the type of

feed being used. You can also [[WordPress:Customizing

Feeds|customize the feed tag]], changing the way it displays the link information about the

feed and type, or even have it feature feed icons instead of text.

最后一个标签是comments_rss_link()，使

用参数RSS 2.0来识别使用的feed类型。你也可以

自定义feed标签，更改它的显示有关feed和模型的连接信息的方式，

或者使用feed图标来代替文本。

Changing the Text

Let's start to rearrange your post meta data with small steps. The first step is to

change the text but not the tags. After all, this is your website and you want it to say

things your way, right? This example makes the post meta data a little more

conversational:

<small>I slaved away at the computer on <?php the_time('l, F jS, Y') ?> 
at the ridiculous time of <?php the_time() ?> when I could have 
been doing something much more productive.  I slapped this 
thing into the <?php the_category(' and ') ?> categories, just 
to make you think I have some organizational skills.  If you 
can really be bothered, you can keep track of what people 
have to say about my silly writings through the 
<?php comments_rss_link('RSS 2.0'); ?> feed, but I 
wouldn't bother.  No one else who reads this babble has 
anything worthwhile to say.</small>

更改文本

让我们开始重新排版你的文章 meta数据。第一步是更改文本而不是标签。毕竟，这是你的网站，你

希望它使用你的方式来排列，对吧？这个例子让文章 meta数据更加会话式：

<small>I slaved away at the computer on <?php the_time('l, F jS, Y') ?> 
at the ridiculous time of <?php the_time() ?> when I could have 
been doing something much more productive.  I slapped this 
thing into the <?php the_category(' and ') ?> categories, just 
to make you think I have some organizational skills.  If you 
can really be bothered, you can keep track of what people 
have to say about my silly writings through the 
<?php comments_rss_link('RSS 2.0'); ?> feed, but I 
wouldn't bother.  No one else who reads this babble has 
anything worthwhile to say.</small>

This would result in:

I slaved away at the

computer on Monday, February 12, 2003 at the ridiculous time of 11:32. when I could have

been doing something much more productive. I slapped this thing into the

[[WordPress:#Changing the Text|WordPress Lessons]] and [[WordPress:#Changing the Text|Things

to Know]]. categories, just to make you think I have some organizational skills. If you can

really be bothered, you can keep track of what people have to say about my silly writings

through the [[WordPress:#Changing the Text|RSS 2.0]] feed, but I wouldn't bother. No one

else who reads this babble has anything worthwhile to say.

显示结果如下：

I slaved away at the

computer on Monday, February 12, 2003 at the ridiculous time of 11:32. when I could have

been doing something much more productive. I slapped this thing into the

[[WordPress:#Changing the Text|WordPress Lessons]] and [[WordPress:#Changing the Text|Things

to Know]]. categories, just to make you think I have some organizational skills. If you can

really be bothered, you can keep track of what people have to say about my silly writings

through the [[WordPress:#Changing the Text|RSS 2.0]] feed, but I wouldn't bother. No one

else who reads this babble has anything worthwhile to say.

Okay, there is a small change. Did you catch it?

The usage of the_category() template tag, the parameter that sets the

separator between the list of categories where the post

belongs, was changed from a comma (,) to the word "and". It makes more sense in

this situation.

好了，有一点小的变化，你发现了吗？

the_category()模板标签的使用，设置分类列表分离器的参数，文章所在的地方，从一个逗号 (,)更改为单词"and"，这样它更加有意义了。

Now, you can also cut the chatter and make your post meta data short and sweet:

POSTED: <?php the_time('m/j/y g:i A') ?><br />
FILED AS: <?php the_category(', ') ?><br />
COMMENTS FEED: <?php comments_rss_link('RSS 2.0'); ?>

现在可以中断一下，让你的文章 meta数据更短，更有味道：

POSTED: <?php the_time('m/j/y g:i A') ?><br />
FILED AS: <?php the_category(', ') ?><br />
COMMENTS FEED: <?php comments_rss_link('RSS 2.0'); ?>

Here is a very short list of your post meta data:

POSTED:

05/12/04 9:35 AM FILED AS: [[WordPress:#Changing the Text|News]], [[WordPress:#Changing the Text|Answers]]

COMMENTS FEED: [[WordPress:#Changing the Text|RSS 2.0]]

这是你的文章 meta数据中很短的一个列表：

POSTED:

05/12/04 9:35 AM FILED AS: [[WordPress:#Changing the Text|News]], [[WordPress:#Changing the Text|Answers]]

COMMENTS FEED: [[WordPress:#Changing the Text|RSS 2.0]]

Changing the Time and Date

There are many ways to change the time and date within your post meta data to reflect a

more appropriate use for your website or your cultural timekeeping methods. For example, in

much of the world, the date is not month day, year but day month year. In the

post meta data, you would change the template tag [[WordPress:Template

Tags/the_time|the_time()]] so the paramters would show "Monday, 21 February 2005":

<?php the_time('1, jS F Y') ?>

更改日期和时间

文章 meta数据中有很多种方法更改时间和日期，来反映出对你的网站或者是你时间文化更合适的用

法，举个例子，世界上很多地方不是月日, 年而是日月, 年。在文章 meta数据中，你可

以改变the_time()模板标签，这样参数就会显

示"Monday, 21 February 2005"了：

<?php the_time('1, jS F Y') ?>

To add more interesting information to your post meta data there are several

plugins available which generate the date the post was last

modified. Two such plugins are [http://guff.szub.net/2005/02/22/post-updated/ Kaf

Oseo's Post Updated] and [http://dev.wp-plugins.org/browser/last-modified/trunk/ Nick

Momrik's Last Modified]. In the following example, using various ways of

manipulating time with PHP tags, we'll add Nick

Momrik's plugin to the mix, mdv_last_modified():

<div class="postmetadata">This post was written on what I 
think was a <?php the_time('l'); ?>, but I know it was 
the <?php the_time('jS'); ?> day in the month 
of <?php the_time('F'); ?> in the year of 
<?php the_time('Y'); ?>, though I messed around 
with this on the <?php mdv_last_modified('dS'); ?> day 
of <?php mdv_last_modified('F'); ?> in 
<?php mdv_last_modified('Y'); ?>, a not-so-busy 
<?php mdv_last_modified('l'); ?> when I had nothing 
better to do.</p></div>

想加入更多有趣的信息到文章 meta数据中，有几种插件可以使用，它们可以得到文章最后更改的时

间。两种这样的插件是[http://guff.szub.net/2005/02/22/post-updated/ Kaf Oseo's Post

Updated] 和[http://dev.wp-plugins.org/browser/last-modified/trunk/ Nick Momrik's Last

Modified]，在下边的例子中，使用manipulating time带有

PHP标签的不同方法，我们会把Nick Momrik的插件加入混合，mdv_last_modified()：

<div class="postmetadata">This post was written on what I 
think was a <?php the_time('l'); ?>, but I know it was 
the <?php the_time('jS'); ?> day in the month 
of <?php the_time('F'); ?> in the year of 
<?php the_time('Y'); ?>, though I messed around 
with this on the <?php mdv_last_modified('dS'); ?> day 
of <?php mdv_last_modified('F'); ?> in 
<?php mdv_last_modified('Y'); ?>, a not-so-busy 
<?php mdv_last_modified('l'); ?> when I had nothing 
better to do.</p></div>

Which would result in:

This post was written on

what I think was a Tuesday, but I know it was the 15th day in the month of February in the

year of 2004, though I messed around with this on the 10th day of August in 2004, a not-so-

busy Thursday when I had nothing better to do.

显示结果如下：

busy Thursday when I had nothing better to do.

Adding Template Tags

So far, you've covered only three of the many template tags you can add to your post meta

data. You can add the the_title() to get

the title of the post. If you want the author's name, you can add [[WordPress:Template

Tags/the_author|the_author()]] and even the author's email with

the_author_email(). Want a link to all the

posts written by a specific author? That can be arranged with the [[WordPress:Template

Tags/the_author_posts_link|the_author_posts_link()]].

添加模板标签

到目前为止，你涉及了可以加入文章 meta数据的仅仅三种标签。你可以添加

the_title()来得到文章的标题。如果你想要作者的名字

，你可以添加the_author()，还可以添加

the_author_email()以得到作者的电子邮件。想

要某个作者的所有文章的连接？可以使用[[WordPress:Template

ags/the_author_posts_link|the_author_posts_link()]]来安排妥当。

What if you want to include more basic information like the title of the website using

bloginfo(), or

navigation help like the [[WordPress:Template

Tags/previous_post|previous_post()]] and [[WordPress:Template

Tags/next_post|next_post()]]? We're using the next and previous post template tags to

list posts within the same category, available to users of WordPress 1.5.1.3+. These are

just a few examples of the many possible uses of template tags in your post meta data

如果你想包括更基本的信息比如网站使用的标题，使用[[WordPress:Template

Tags/bloginfo|bloginfo()]]或者导航帮助如

previous_post()和[[WordPress:Template

Tags/next_post|next_post()]]？我们使用WordPress 1.5.1.3+的使用者可用的，上一个和下一个

文章模板标签来列出同一列表中的文章。这些只是文章 meta数据中很多可能的模板标签用法的几个

例子。

In the most simplest of usages, the post meta data could be listed as:

POST TITLE: <?php the_title(); ?><br />
AUTHOR: <?php the_author(); ?><br />
POSTED: <?php the_time('jS F Y') ?><br />
FILED AS: <?php the_category(', ') ?><br />
COMMENT FEED: <?php comments_rss_link('RSS 2.0'); ?><br />
PREVIOUS: <?php previous_post('%', '', 'yes', 'yes'); ?><br />
NEXT: <?php next_post('%', '', 'yes', 'yes'); ?>

在最简单的用法中，文章 meta数据可以如下列出

POST TITLE: <?php the_title(); ?><br />
AUTHOR: <?php the_author(); ?><br />
POSTED: <?php the_time('jS F Y') ?><br />
FILED AS: <?php the_category(', ') ?><br />
COMMENT FEED: <?php comments_rss_link('RSS 2.0'); ?><br />
PREVIOUS: <?php previous_post('%', '', 'yes', 'yes'); ?><br />
NEXT: <?php next_post('%', '', 'yes', 'yes'); ?>

And would look like this:

POST TITLE:

[[WordPress:#Adding Template Tags|WordPress Makes Me Smile]]
AUTHOR: [[WordPress:#Adding Template Tags|Harriet Smith]]
POSTED: 20 April 2004
FILED AS: [[WordPress:#Adding Template Tags|WordPress]], [[WordPress:#Adding Template

NEXT: [[WordPress:#Adding Template Tags|Why I Like WordPress]]

If you want this in your sidebar, and you want a more conversational style, then in your

template file, sidebar.php, find a good spot to put the

following:

<div class="postmetadata"><p>You are reading the article, 
<?php the_title(); ?>, on our website, <?php bloginfo('name'); ?>.  
This article was written on <?php the_time('jS F Y') ?>, in 
Seattle, Washington, and you can find similar articles in 
the <?php the_category(' and ') ?> categories, or more articles 
by <?php |the_author_posts_link() ?>, if you enjoyed this article.  
If you have any comments about this article, you can contact 
<?php the_author() ?> by <a href="mailto:<?php the_author_email(); ?>">
email</a>, or leave a comment below.  You can also follow comments 
made on this article via our <?php comments_rss_link('RSS 2.0'); ?> 
feed.</p>
<p>If you would like to continue reading more, 
<?php previous_post('the previous article on our site is called %', ' ', 'yes', 'yes'); ?>
<?php next_post(' and the next article is called %', ' ', 'yes', 'yes'); ?>.
  Thank you for visiting our site.</p></div>

如果你想让这些内容显示在边栏中，而且你想要一个会话式的样式，那么在你的模板文件中，sidebar.php，找一个地方输入以下内容：

<div class="postmetadata"><p>You are reading the article, 
<?php the_title(); ?>, on our website, <?php bloginfo('name'); ?>.  
This article was written on <?php the_time('jS F Y') ?>, in 
Seattle, Washington, and you can find similar articles in 
the <?php the_category(' and ') ?> categories, or more articles 
by <?php |the_author_posts_link() ?>, if you enjoyed this article.  
If you have any comments about this article, you can contact 
<?php the_author() ?> by <a href="mailto:<?php the_author_email(); ?>">
email</a>, or leave a comment below.  You can also follow comments 
made on this article via our <?php comments_rss_link('RSS 2.0'); ?> 
feed.</p>
<p>If you would like to continue reading more, 
<?php previous_post('the previous article on our site is called %', ' ', 'yes', 'yes'); ?>
<?php next_post(' and the next article is called %', ' ', 'yes', 'yes'); ?>.
  Thank you for visiting our site.</p></div>

This example, if styled in a narrow column found on most sidebars, would look like this:

You are reading the article, [[WordPress:#Adding Template Tags|WordPress Makes Me

Smile]], on our website, [[WordPress:#Adding Template Tags|Talking Blog]]. This article was

written on May 15, 2004, in Seattle, Washington, and you can find similar articles in the

[[WordPress:#Adding Template Tags|WordPress]] and [[WordPress:#Adding Template Tags|Blog]]

categories, or more articles by [[WordPress:#Adding Template Tags|Harriet Smith]], if you

enjoyed this article. If you have any comments about this article, you can contact Harriet

Smith by [[WordPress:#Adding Template Tags|email]], or leave a comment below. You can also

follow comments made on this article via our [[WordPress:#Adding Template Tags|RSS 2.0]]
