function single_month_title($prefix = '', $display = true ) {}
Display or retrieve page title for post archive based on date.
Useful for when the template only needs to display the month and year, if either are available. Optimized for just this purpose, so if it is all that is needed, should be better than wp_title().
Parameters
- string $prefix: Optional. What to display before the title.
- bool $display: Optional, default is true. Whether to display or retrieve title.
Return values
returns:Title when retrieving, null when displaying or failure.
Source code
function single_month_title($prefix = '', $display = true ) {
global $wp_locale;
$m = get_query_var('m');
$year = get_query_var('year');
$monthnum = get_query_var('monthnum');
if ( !empty($monthnum) && !empty($year) ) {
$my_year = $year;
$my_month = $wp_locale->get_month($monthnum);
} elseif ( !empty($m) ) {
$my_year = substr($m, 0, 4);
$my_month = $wp_locale->get_month(substr($m, 4, 2));
}
if ( empty($my_month) )
return false;
$result = $prefix . $my_month . $prefix . $my_year;
if ( !$display )
return $result;
echo $result;
}
