源文件
get_attachment_template() 函数的代码位于 wp-includes/template.php.
/**
* Retrieve path of attachment template in current or parent template.
*
* The attachment path first checks if the first part of the mime type exists.
* The second check is for the second part of the mime type. The last check is
* for both types separated by an underscore. If neither are found then the file
* ‘attachment.php’ is checked and returned.
*
* Some examples for the ‘text/plain’ mime type are ‘text.php’, ‘plain.php’, and
* finally ‘text-plain.php’.
*
* The template path is filterable via the dynamic {@see ‘$type_template’} hook,
* e.g. ‘attachment_template’.
*
* @since 2.0.0
*
* @see get_query_template()
*
* @global array $posts
*
* @return string Full path to attachment template file.
