如果通过" 博客页面"表示您是在阅读设置中设置为帖子页面的静态页面,那么您可以通过执行以下操作进行检查:

 if ( is_front_page() && is_home() ) {
  // Default homepage
} elseif ( is_front_page() ) {
  // static homepage
} elseif ( is_home() ) {
  // blog page
} else {
  //everyting else
}

当使用is_home()和is_front_page()时,必须在 正确的顺序,以避免错误并测试每个用户配置.

(来源: 条件标签-博客页面 )

或者简单地:

 if ( !is_front_page() && is_home() ) {
  // blog page
}

或更简单地说(我想):

 if ( is_home() ) {
  // blog page
}

If by 'blog page' you meant a static page set as posts page in the Reading Settings, then you could check it by doing this:

if ( is_front_page() && is_home() ) {
  // Default homepage
} elseif ( is_front_page() ) {
  // static homepage
} elseif ( is_home() ) {
  // blog page
} else {
  //everyting else
}

When you use is_home() and is_front_page(), you have to use them in the right order to avoid bugs and to test every user configuration.

(Source: Conditional Tags - The Blog Page)

Or simply:

if ( !is_front_page() && is_home() ) {
  // blog page
}

Or more simply (I suppose):

if ( is_home() ) {
  // blog page
}

至少在我看来,使用`if(！is_front_page()&&is_home())`的一种用例是,如果您要为**默认首页**和**blog分配具有不同布局样式的主题页**.

One use case to use `if ( !is_front_page() && is_home() )`, at least in my opinion, is if you are distributing a theme that has different layout style for the **default homepage** and the **blog page**.

我发现无论是否选择博客存档或页面,is_front_page()都将返回true.需要验证.https://codex.wordpress.org/Function_Reference/is_front_page

I'm finding is_front_page() will return true whether or not the blog archive or a page is selected. Need verification. https://codex.wordpress.org/Function_Reference/is_front_page

您可以在主题functions.php文件中使用以下内容:

 function is_blog () {
    return ( is_archive() || is_author() || is_category() || is_home() || is_single() || is_tag()) && 'post' == get_post_type();
}

然后将其放入要检查的文件中

 <?php if (is_blog()) { echo 'You are on a blog page'; } ?>

您可以在functions.php文件中使用Hooks来挂钩上述内容,以使其出现在每个页面上.

You can use the following in your themes functions.php file:

function is_blog () {
    return ( is_archive() || is_author() || is_category() || is_home() || is_single() || is_tag()) && 'post' == get_post_type();
}

And then put this in the file you are checking:

<?php if (is_blog()) { echo 'You are on a blog page'; } ?>

You can use Hooks in your functions.php file to hook the above, to make that appear on every page.

如果您想确定自己是否在_a_博客页面上,而不必在_the_博客页面上(如博客主页中一样),则这是一个很好的答案.参见@Giraldi的答案.

This is a great answer if you want to determine if you're on _a_ blog page, but not neccessarily _the_ blog page (as in the blog home page). See @Giraldi's answer for that.

我错误地认为is_blog()存在,因为is_page()存在.我没有想到要查阅[官方WordPress条件标签索引](https://codex.wordpress.org/Conditional_Tags#Conditional_Tags_Index).我能够使用Widget Logic插件有效地应用此解决方案.

I incorrectly assumed is_blog() exists because is_page() exists. It didn't occur to me to consult the [official WordPress Conditional Tags Index](https://codex.wordpress.org/Conditional_Tags#Conditional_Tags_Index). I was able to effectively apply this solution using the Widget Logic plugin.

如果"博客页面"是指在阅读中将静态页面设置为帖子页面:

 global $wp_query;

if ( isset( $wp_query ) && (bool) $wp_query->is_posts_page ) {
    //static blog page
}

PS.此解决方案还适用于template_redirect 操作

If by 'blog page' you meant a static page set as posts page in the Reading:

global $wp_query;

if ( isset( $wp_query ) && (bool) $wp_query->is_posts_page ) {
    //static blog page
}

PS. This solution also works on template_redirect action

嗨,repinsa,欢迎来到WPSE :)感谢您添加答案.它被否决了,可能是因为它在代码中存在语法错误(在`global $ wp_query`之后遗漏了分号),还因为它没有完全回答问题.这是一个函数,但是OP在他的头文件中询问如何解决这个问题-因此可能需要更多关于放置位置的解释.再次欢迎您,很高兴有您在这里！

Hi repinsa, welcome to WPSE :) Thanks for adding your answer. It's been voted down a bit, probably because it has a syntax error in the code (it's missing a semicolon after the `global $wp_query`) but also because it doesn't fully answer the question. It's a function, but the OP asked how to work this out in his header file - so it might need a little more explanation about what to put where. Again, welcome, glad to have you here!

That's actually the only good answer here, should have had more upvotes.

要获取博客索引页面,我发现

 if ( !is_front_page() && is_home() ) {
  // blog page
}

对我不起作用,我不得不使用get_option('page_for_posts')函数来标识Blog页面post_id,我的答案是

 if ( !is_front_page() && is_home() ){  

    if ( empty ( $post_id) ) {
        global $post;
        $post_id =  get_option( 'page_for_posts' );
    }

    //blog page
}

To get the blog index page, I found that

if ( !is_front_page() && is_home() ) {
  // blog page
}

is not working for me, I had to use the get_option('page_for_posts') function to identify the Blog Page post_id, my answer is

if ( !is_front_page() && is_home() ){  

    if ( empty ( $post_id) ) {
        global $post;
        $post_id =  get_option( 'page_for_posts' );
    }

    //blog page
}

您可以使用..

 <?php if ( is_single() ) { ?>

Do stuff here

<?php } ?>

检查它是否是一篇博客文章.或者...

 <?php if ( is_home() ) { ?>

Do stuff here

<?php } ?>

检查是否是博客主页

You can use..

<?php if ( is_single() ) { ?>

Do stuff here

<?php } ?>

to check if it's a single blog post. Or...

<?php if ( is_home() ) { ?>

Do stuff here

<?php } ?>

to check if it's the blog homepage

如果您更改了博客页面,则无法使用

Doesn't work if you've changed the blog page

这不能为OP提供正确的答案.这表明您在单个帖子上,而不是"博客页面".

This doesn't provide a correct answer to the OP. This indicates you are on a single post, not "the blog page".

有一个棘手的方法.

http://example.com/blog

假设您的博客页面标签为 blog ,则可以使用此代码.

 global $wp_query;
if($wp_query->query['pagename']=='blog'){
// this is blog page
}

There is a tricky method.

http://example.com/blog

Suppose if your blog page slug is blog, you can use this code.

global $wp_query;
if($wp_query->query['pagename']=='blog'){
// this is blog page
}

 ...
endif;

我想我处于相同的情况下非常简单,我使用了以下技术来使用页塞.

 if( is_page('blog') ) {
echo "This is your blog page"; 
}

但是请确保您没有选择主页来显示最近的博客文章,并且已为博客或新闻等博客设置了特定页面,只需使用该页面标签,就可以了.

I guess its very simple I was in a same situation and I used the following technique which is to use the page slug.

if( is_page('blog') ) {
echo "This is your blog page"; 
}

But make sure you've not selected homepage to display recent blog posts and you have set a specific page for blogs like blog or news etc, just use that page slug and you'd be fine.

我用这种方式

 // Get body classes as array
$body_classes = get_body_class();
// Check if "blog" class exists in the array
if(in_array("blog", $body_classes)) {
   // Do stuff
}

I use this way

// Get body classes as array
$body_classes = get_body_class();
// Check if "blog" class exists in the array
if(in_array("blog", $body_classes)) {
   // Do stuff
}
