经常做WordPress开发的同学应该也常常使用到 get_the_time() 函数 ,get_the_time()函数可以用来获取并显示当前文章发布的时间；该函数后面可以跟控制日期或时间格式的参数，调用的格式为 : ,有两个参数 $d 、 $post ;
参数 $d 为字符串，主要作用是就是指定输出日期的格式，可选，默认为Wordpress常规设置中的日期格式。
参数 $post 为整数或对像，可以是文章ID或日期对像，可选，默认为文章ID。
get_the_time()函数的官方帮助文档链接：http://codex.wordpress.org/Function_Reference/get_the_time
下面我们来详细介绍下参数 $d ,即日期格式化字符串：(官方参考文档：http://codex.wordpress.org/Formatting_Date_and_Time)
Certain WordPress tag functions are used to display or return date and time information; the_date() and the_time() are examples of this. Some of these functions accept a parameter called a format string that allows you to determine how the date is going to be displayed. The format string is a template in which various parts of the date are combined (using “format characters”) to generate a date in the format specified.
For example, the format string:
l, F j, Y
creates a date that look like this:
Friday, September 24, 2004
Here is what each format character in the string above represents:
-
l= Full name for day of the week (lower-case L). -
F= Full name for the month. -
j= The day of the month. -
Y= The year in 4 digits. (lower-case y gives the year’s last 2 digits)
- (Commas are read literally.)
WordPress is written in the programming language PHP. The date formatting functions in WordPress use PHP’s built-in date formatting functions. You can use the table of date format characters on the PHP website as a reference for building date format strings for use in WordPress. Here is a table of some of the more useful items found there:
| Day of Month | ||
|---|---|---|
| d | Numeric, with leading zeros | 01–31 |
| j | Numeric, without leading zeros | 1–31 |
| S | The English suffix for the day of the month | st, nd or th in the 1st, 2nd or 15th. |
| Weekday | ||
| l | Full name (lowercase ‘L’) | Sunday – Saturday |
| D | Three letter name | Mon – Sun |
| Month | ||
| m | Numeric, with leading zeros | 01–12 |
| n | Numeric, without leading zeros | 1–12 |
| F | Textual full | January – December |
| M | Textual three letters | Jan – Dec |
| Year | ||
| Y | Numeric, 4 digits | Eg., 1999, 2003 |
| y | Numeric, 2 digits | Eg., 99, 03 |
| Time | ||
| a | Lowercase | am, pm |
| A | Uppercase | AM, PM |
| g | Hour, 12-hour, without leading zeros | 1–12 |
| h | Hour, 12-hour, with leading zeros | 01–12 |
| G | Hour, 24-hour, without leading zeros | 0-23 |
| H | Hour, 24-hour, with leading zeros | 00-23 |
| i | Minutes, with leading zeros | 00-59 |
| s | Seconds, with leading zeros | 00-59 |
| T | Timezone abbreviation | Eg., EST, MDT … |
| Full Date/Time | ||
| c | ISO 8601 | 2004-02-12T15:19:21+00:00 |
| r | RFC 2822 | Thu, 21 Dec 2000 16:01:07 +0200 |
Examples
Here are some examples of date format and result output.
-
F j, Y g:i a– November 6, 2010 12:50 am -
F j, Y– November 6, 2010 -
F, Y– November, 2010 -
g:i a– 12:50 am -
g:i:s a– 12:50:48 am -
l, F jS, Y– Saturday, November 6th, 2010 -
M j, Y @ G:i– Nov 6, 2010 @ 0:50 -
Y/m/d \a\t g:i A– 2010/11/06 at 12:50 AM -
Y/m/d \a\t g:ia– 2010/11/06 at 12:50am -
Y/m/d g:i:s A– 2010/11/06 12:50:48 AM -
Y/m/d– 2010/11/06
Combined with the_time() template tag, the code below in the template file:
This entry was posted on <?php the_time('l, F jS, Y') ?> and is filed under <?php the_category(', ') ?>.
