推荐答案

您最好编辑页面模板以简单地输出日期；它更快，并且更明显，以后更容易找到.通过过滤器应用内容会使跟踪内容来自哪里变得更加困难.

You'd probably be better off editing your page templates to simply output the date; it's quicker and makes it much more obvious and easier to find later on. Apply content via filters can make it harder to tracker down where content is coming from.

话虽如此，如果您决定通过过滤器来实现，以下是您需要添加到您的 functions.php 文件中的内容:

Having said that, if you're determined to do it via filters, here's what you'd need to add to your functions.php file:

/* Adds date to end of title 
 * @uses Hooked to 'the_title' filter
 * @args $title(string) - Incoming title
 * @args $id(int) - The post ID
 */
function my_add_date_to_title($title, $id) {

    // Check if we're in the loop or not
    // This should exclude menu items
    if ( !is_admin() && in_the_loop() ) {

        // First get the default date format
        // Alternatively, you can specify your 
        // own date format instead
        $date_format = get_option('date_format');

        // Now get the date
        $date = get_the_date($date_format, $id); // Should return a string

        // Now put our string together and return it
        // You can of course tweak the markup here if you want
        $title .= ' (' . $date . ')';
     }

    // Now return the string
    return $title;
}

// Hook our function to the 'the_title' filter
// Note the last arg: we specify '2' because we want the filter
// to pass us both the title AND the ID to our function
add_filter('the_title','my_add_date_to_title',10,2);

未经测试，但应该可以工作.

Not tested, but should work.
