Lo del las ligas al diario oficial de la federación (DOF) ya funciona perfectamente, uso el URL del DOF (que usa fechas para desplegar la inforamción). Eso no es ya el problema, sino que el calendario de Wordpress te permite desplazarte mientras existan posts en los distintos meses, y yo quiero que te muevas a través de los meses sin ninguna limitante.
Este es el código del calendario. Ya está modificado para que ponga el link en todos los días y no solo cuando existan posts.
Código PHP:
function get_calendar($initial = true, $echo = true) {
global $wpdb, $m, $monthnum, $year, $wp_locale, $posts;
$cache = array();
$key = md5( $m . $monthnum . $year );
if ( $cache = wp_cache_get( 'get_calendar', 'calendar' ) ) {
if ( is_array($cache) && isset( $cache[ $key ] ) ) {
if ( $echo ) {
echo apply_filters( 'get_calendar', $cache[$key] );
return;
} else {
return apply_filters( 'get_calendar', $cache[$key] );
}
}
}
if ( !is_array($cache) )
$cache = array();
// Quick check. If we have no posts at all, abort!
if ( !$posts ) {
$gotsome = $wpdb->get_var("SELECT 1 as test FROM $wpdb->posts WHERE post_type = 'post' AND post_status = 'publish' LIMIT 1");
if ( !$gotsome ) {
$cache[ $key ] = '';
wp_cache_set( 'get_calendar', $cache, 'calendar' );
return;
}
}
if ( isset($_GET['w']) )
$w = ''.intval($_GET['w']);
// week_begins = 0 stands for Sunday
$week_begins = intval(get_option('start_of_week'));
// Let's figure out when we are
if ( !empty($monthnum) && !empty($year) ) {
$thismonth = ''.zeroise(intval($monthnum), 2);
$thisyear = ''.intval($year);
} elseif ( !empty($w) ) {
// We need to get the month from MySQL
$thisyear = ''.intval(substr($m, 0, 4));
$d = (($w - 1) * 7) + 6; //it seems MySQL's weeks disagree with PHP's
$thismonth = $wpdb->get_var("SELECT DATE_FORMAT((DATE_ADD('{$thisyear}0101', INTERVAL $d DAY) ), '%m')");
} elseif ( !empty($m) ) {
$thisyear = ''.intval(substr($m, 0, 4));
if ( strlen($m) < 6 )
$thismonth = '01';
else
$thismonth = ''.zeroise(intval(substr($m, 4, 2)), 2);
} else {
$thisyear = gmdate('Y', current_time('timestamp'));
$thismonth = gmdate('m', current_time('timestamp'));
}
$unixmonth = mktime(0, 0 , 0, $thismonth, 1, $thisyear);
