Using get_calendar to display previous months?

(@deadmentor)

Thanks for responding! That makes a lot of sense, but — and I apologize for this — I just don’t know how to do what you suggested. I copied and pasted the code into my functions.php file and renamed the get_calendar function no problem — but that’s as far as I got.

Do you think you could break the rest of it down into steps for me?

Thank you very much for your time and patience!

Best,
Osgood

PS. Also, will this update every month so that it always displays the previous month? That’s important.

This will update every month so the the calendar is always of the previous month

step 1 make copy of get_calendar function

step 2 add a filter and a callback function (ucc_get_calendar_filter)

the filter says to wordpress when get_calendar function is called do ucc_get_calendar instead

here’s code that makes it previous month instead of current one

$thismonth = ''.zeroise(intval($thismonth - 1), 2);
	if ($thismonth == '0'){
		$thismonth = 12;
		$thisyear = intval($thisyear - 1);
	}

and everything together:

function ucc_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!

			$cache[ $key ] = '';
			wp_cache_set( 'get_calendar', $cache, 'calendar' );
			return;
		}
	}

		$w = ''.intval($_GET['w']);

	// week_begins = 0 stands for Sunday

That works exactly! Thank you for your help.

Unfortunately, I’ve realized that this won’t accomplish my utmost goal, which is to display two months worth of posts in calendar form, the current month AND the previous month. I thought knowing how to display the previous month would solve my problem, but of course it doesn’t.

I’d be grateful for any help or insight you have into accomplishing this — but you’ve already done so much, and I understand if you’d like to move on.

Regardless, thank you very much for your time and assistance. I learned a lot.

Best,
Osgood

(@jdavhar)

decide if you need the next and prev links to still work,
by default i understand you want this months and previous months posts in calendar form, but do you want previous button to be below them so they can see previous two months if they click it, and then go forwards or keep going back until no more posts?

Thread Starter

(@deadmentor)

Yes, ideally I’d like the previous and next links to work in the way you describe, that is showing the previous/next two months. But having those links isn’t THAT important, if it’s too complicated or time-intensive for you.

Again, thank you so much for your help. You’re making my day!

Best,
Osgood

(@jdavhar)

nvm that doesnt work ??

Really, the most important thing is displaying the two months at once, current and previous. That’s the key. Everything else is dessert!
