如何获取PHP中的主题URL？

此功能将返回主题目录URL,以便您可以在其他功能中使用它:

 get_bloginfo('template_directory');
 

或者,此功能将回显主题目录URL到浏览器:

 bloginfo('template_directory');
 

因此,主题images/headers文件夹中的图像的示例为:

 <img src="<?php bloginfo('template_directory'); ?>/images/headers/image.jpg" />
 

This function will return the theme directory URL so you can use it in other functions:

get_bloginfo('template_directory');

Alternatively, this function will echo the theme directory URL to the browser:

bloginfo('template_directory');

So an example for an image in the themes images/headers folder would be:

<img src="<?php bloginfo('template_directory'); ?>/images/headers/image.jpg" />

@EAMann 所说的,但有警告.埃里克(Eric)关于通用方法以及bloginfo()和get_bloginfo()函数如何工作以及如何传递参数'template_directory'是正确的以获得您(大多数)主题所需的价值.

但是需要注意的是, caveat 与更新的 Child Themes 有关.如果您使用的是子主题,那么'template_directory'可能不是您想要的,除非您实际上尝试引用父主题目录中的图像.取而代之的是,对于子主题,您可能想要通过 stylesheet_directory (我知道,名字不告诉您它们是什么,但是,嘿,这就是这样！) Eric使用 stylesheet_directory 的回复看起来像这样(我简化了示例,所以它不会包装):

＆lt;img src="＆lt;?phpbloginfo('stylesheet_directory');?＆gt;/images/header.jpg"/＆gt;

为了说明我编写的一个快速独立文件的观点,您可以将其根目录放置为test.php 并运行以查看其输出.首先以TwentyTen这样的常规主题运行,然后以子主题运行:

 ＆lt;?php
/*
*test.php-测试常规主题和子主题之间的区别
*
*/

包括" wp-load.php"；

$bloginfo_params=数组(
    'admin_email',
    'atom_url',
    "字符集",
    'comments_atom_url',
    'comments_rss2_url',
    '描述',
    '家',
    'html_type',
    '语言',
    '名称',
    'pingback_url',
    'rdf_url',
    'rss2_url',
    'rss_url',
    " siteurl",
    'stylesheet_directory',
    'stylesheet_url',
    'template_directory',
    'template_url',
    'text_direction',
    'url',
    '版',
    " wpurl",
);

回声'＆lt;tableborder=" 1"＆gt;';
foreach($bloginfo_params as $param){
    $info=get_bloginfo($param);
 echo"＆lt;tr＆lt;th＆gt; {$param}:＆lt;/th＆lt;td＆gt; {$info}＆lt;/td＆lt;/tr＆gt;";
}
回声'＆lt;/table＆gt;';
 

如果您发现了什么,您可能会注意到传递给bloginfo()和get_bloginfo()的内容还有很多.请研究下面的代码和屏幕截图以获取想法.

看截图,您可以看到对于常规主题, stylesheet_directory 返回的内容与'template_directory'相同,但是值有所不同,可能还需要一个儿童主题.

为清晰起见, wp30.dev 是仅运行的域 在我的本地计算机上.目前是 WordPress 3.0.1的实例及其 配置为 127.0.0.1 (与 localhost ),然后使用它 用于测试类似的临时示例. 我在Mac OS X上使用 VirtualHostX 作为便利来帮助我设置那些私有的不可路由的 .dev 域,但任何人都可以通过以下方式手动完成 编辑计算机的主机文件和 ? httpd.conf文件.

如果您不熟悉 儿童主题 ,顺便说一下,还有另外两个可能有帮助的WordPress答案:

• 将标题设为20主题不太高?
• 自定义WordPress主题而不进行更改?

What @EAMann said, with a caveat. Eric is right about the general approach and how the functions bloginfo() and get_bloginfo() work and about how to pass the parameter 'template_directory' to get the value you need for (most) themes.

However there is a caveat and that caveat is with the newer Child Themes. If you are using a child theme then 'template_directory' is probably not what you want unless you are actually trying to refer to an image that is in the parent theme directory. Instead for child themes what you probably want is to pass stylesheet_directory (I know, I know, the names don't tell you what they are but hey, that's just the way it is!) Borrowing somewhat from Eric's reply using stylesheet_directory would look like this (I shortened the example so it would not wrap):

<img src="<?php bloginfo('stylesheet_directory'); ?>/images/header.jpg" />

To illustrate the point I wrote a quick standalone file you can drop in your website's root as test.php and run to see what it outputs. First run with a regular theme like TwentyTen then run with a child theme:

<?php
/*
* test.php - Test the difference between Regular and Child Themes
*
*/

include "wp-load.php";

$bloginfo_params = array(
    'admin_email',
    'atom_url',
    'charset',
    'comments_atom_url',
    'comments_rss2_url',
    'description',
    'home',
    'html_type',
    'language',
    'name',
    'pingback_url',
    'rdf_url',
    'rss2_url',
    'rss_url',
    'siteurl',
    'stylesheet_directory',
    'stylesheet_url',
    'template_directory',
    'template_url',
    'text_direction',
    'url',
    'version',
    'wpurl',
);

echo '<table border="1">';
foreach($bloginfo_params as $param) {
    $info = get_bloginfo($param);
    echo "<tr><th>{$param}:</th><td>{$info}</td></tr>";
}
echo '</table>';

If you notice things you might notice that there's a lot more to what you can pass to bloginfo() and get_bloginfo(); study the code and the screenshot below for ideas.

Looking at the screenshot you can see that stylesheet_directory returns the same thing as 'template_directory' for a regular theme but a different value, and probably the value you need for a child theme.

For clarity on this screenshot, wp30.dev is a domain that runs only on my local computer. It is currently an instance of WordPress 3.0.1 and it is configured at 127.0.0.1 (same as localhost) on my laptop and I use it for testing ad-hoc examples like this. I used VirtualHostX as a convenience on the Mac OS X to help me set up those private non-routable .dev domains but anyone can do it manually by editing the computer's hosts file and the ? httpd.conf file.

By the way, in case you are not familiar with Child Themes where are two other WordPress Answers that might help:

• Making the Header on the Twenty Ten Theme Less Tall?
• Customizing a WordPress Theme without Changing it?

主题的整个结构基于两个选项-template (保存父主题文件夹名称)和 stylesheet (保存子主题文件夹名称).如果没有使用子主题,则它们是相同的.

要具有过滤器的灵活性,而不是直接访问选项,因此有 get_template() 和 get_stylesheet() .

现在唯一缺少的是将那些与主题文件夹位置组合在一起.可以使用 get_theme_root_uri() 来完成,并再次方便地包装在 get_template_directory_uri() 和 < code>get_stylesheet_directory_uri() .

[get_]bloginfo() 和template_directory 或 stylesheet_directory 参数只是将它们包装起来,因此没有理由使用它.我要说的是,只有通过说目录(通常与本地路径有关)而返回URL来混淆.

摘要:

• 使用get_template_directory_uri()引用仅父主题
• 使用get_stylesheet_directory_uri()来仅儿童还是儿童主题

The whole structure of theme builds on top of two options - template (holding parent theme folder namre) and stylesheet (holding child theme folder namr). If there is no child theme used these are the same.

To have flexibility of filters, rather than access option directly, there are accordingly get_template() and get_stylesheet().

Now the only thing is missing is to combine those with themes folder location. This can be done with get_theme_root_uri() and again conveniently wrapped in get_template_directory_uri() and get_stylesheet_directory_uri().

[get_]bloginfo() with template_directory or stylesheet_directory arguments merely wraps these and there is little reason to use it like that. I'd say it is only confusing by having argument saying directory (commonly relates to local paths), but returning URLs.

Sumary:

• use get_template_directory_uri() to refer to only or parent theme
• use get_stylesheet_directory_uri() to only or child theme

我用这个 (dirname(get_bloginfo('stylesheet_url')))

I use this (dirname(get_bloginfo('stylesheet_url')))
