comments_template() 参数

示例

Default Usage

/* ----------------------------------

 * ---------------------------------- */

<?php comments_template(); ?> 

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:

/* ----------------------------------
 * wordpress之魂 © http://wphun.com
 * ---------------------------------- */

<?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:

/* ----------------------------------
 * wordpress之魂 © http://wphun.com
 * ---------------------------------- */

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