comments_template( string $file = '/comments.php', bool $separate_comments = false )

Load the comment template specified in $file.


Description Description

Will not display the comments template if not on single post or page, or if the post does not have comments.

Uses the WordPress database object to query for the comments. The comments are passed through the ‘comments_array’ filter hook with the list of comments and the post ID respectively.

The $file path is passed through a filter hook called ‘comments_template’, which includes the TEMPLATEPATH and $file combined. Tries the $filtered path first and if it fails it will require the default comment template from the default theme. If either does not exist, then the WordPress process will be halted. It is advised for that reason, that the default theme is not deleted.

Will not try to get the comments if the post has none.


Parameters Parameters

$file

(string) (Optional) The file to load.

Default value: '/comments.php'

$separate_comments

(bool) (Optional) Whether to separate the comments by comment type.

Default value: false

    Alternative Comment Template
    On some occasions you may want display your comments differently within your theme. For this you would build an alternate file (ex. short-comments.php) and call it as follows:

    <?php comments_template( '/short-comments.php' ); ?> 
    

    The path to the file used for an alternative comments template should be relative to the current theme root directory, and include any subfolders. So if the custom comments template is in a folder inside the theme, it may look like this when called:

    <?php comments_template( '/custom-templates/alternative-comments.php' ); ?>
