wp_count_posts( string $type = 'post', string $perm = '' )

Count number of posts of a post type and if user has permissions to view.


Description Description

This function provides an efficient method of finding the amount of post’s type a blog has. Another method is to count the amount of items in get_posts(), but that method has a lot of overhead with doing so. Therefore, when developing for 2.5+, use this function instead.

The $perm parameter checks for ‘readable’ value and if the user can read private posts, it will display that for the user that is signed in.


Parameters Parameters

$type

(string) (Optional) Post type to retrieve count.

Default value: 'post'

$perm

(string) (Optional) 'readable' or empty.

Default value: ''

    Get the Publish Status Post Count

    To get the published status type, you would call the wp_count_posts() function and then access the ‘publish’ property.

    $count_posts = wp_count_posts();
    
    if ( $count_oosts ) {
    	$published_posts = $count_posts->publish;
    }
    

    If you are developing for PHP5 only, then you can use shorthand, if you only want to get one status. This will not work in PHP4 and if you want to maintain backwards compatibility, then you must use the above code.

    $published_posts = wp_count_posts()->publish;
