function is_blog () { | |

return ( ((is_archive()) || (is_author()) || (is_category()) || (is_home()) || (is_single()) || (is_tag())) && ( $posttype == 'post') ) ? true : false ; | |

Usage: | |
<?php if (is_blog()) { echo 'You are on a blog page'; } ?> |
@gavinsmith Ah yeah, does is_archive() trigger on CPT archive?
Updated it to ignore custom post types
Thanks for this function, exactly what I needed today. I can't believe it's not a builtin!
Thanks @wesbos!
Very helpful, thanks! However, the is_archive() function covers the is_post_type_archive(), is_date(), is_author(), is_category(), is_tag(), and is_tax() functions, so you can safely remove them. See http://core.trac.wordpress.org/browser/tags/3.4.1/wp-includes/query.php#L1572.
The revised function might look like:
/**
* WordPress' missing is_blog_page() function. Determines if the currently viewed page is
* one of the blog pages, including the blog home page, archive, category/tag, author, or single
* post pages.
*
* @return bool
*/
function is_blog_page() {
global $post;
//Post type must be 'post'.
$post_type = get_post_type($post);
//Check all blog-related conditional tags, as well as the current post type,
//to determine if we're viewing a blog page.
return (
( is_home() || is_archive() || is_single() )
&& ($post_type == 'post')
) ? true : false ;
}
The ? true : false
at the end is not needed. The function will return boolean anyway.
Does this function register early enough to use it in a pre_get_posts action?
is_archive! but what about is_search() ?! even this contains on blog posts
Awesome. So useful, thanks!
How about this:
function is_blog(){
if ( is_front_page() && is_home() ) {
return false;
} elseif ( is_front_page() ) {
return false;
} elseif ( is_home() ) {
return get_option( 'page_for_posts' ); // Returns blog page ID
} else {
return false;
}
}

Less verbose:
function is_blog() {
return ( is_author() || is_category() || is_tag() || is_date() || is_home() || is_single() ) && 'post' == get_post_type();
}
I removed is_archive
because I am using custom post types and taxonomies.
How about this?
in fact, is_singular()
is the same as if ( is_single() || is_page() || is_attachment() )
if ( is_singular( 'post' ) ) {
echo 'You are on a blog page';
}
Taking @grantnorwood's code from 2012:
- The ternary return is unnecessary so let's just return the comparisons.
- Also,
$post_type == 'post'
is the cheaper operation so let's put it first. - Finally using triple equals as there should be no type conversion.
/**
* WordPress' missing is_blog_page() function. Determines if the currently viewed page is
* one of the blog pages, including the blog home page, archive, category/tag, author, or single
* post pages.
*
* @return bool
*/
function is_blog_page()
{
global $post;
// Post type must be 'post'.
$post_type = get_post_type($post);
// Check all blog-related conditional tags, as well as the current post type,
// to determine if we're viewing a blog page.
return ( $post_type === 'post' ) && ( is_home() || is_archive() || is_single() );
}
Has anyone noticed that this fails when there are no posts assigned to a tag or category? $post is NULL when you visit a category/tag archive that has no posts to display. I've been using this for years and seen it on and off - i mostly use this just for page titles, which weren't showing in this case. I never looked into it because usually the categories/tags fill up with posts and it's not an issue! But clients sometimes...
The only stubborn component currently difficult to check for consistently (across all installs) is custom post type indexes.
