Extracting the next 7 days from phpiCalendar to simple HTML

A Tech article with View Comments posted 1 July 2006.

Edit: Newer versions of phpiCalendar give you this feature without the hackery. See the comments for this post.

You’ll need a working installation of PHP (duh), phpiCalendar 2.0beta (or newer), and MagpieRSS If you get errors about re-defining functions, comment out the “require_once” line below, (for instance if you’ve already installed it as part of your WordPress installation) you’ve already got MagpieRSS.

1. Install phpiCalendar and get it working properly.
2. In phpiCalendar “rss/rss.php” change this:

   if ($rssview == "day") {
     $theview = $lang['l_day'];
   } elseif {
     $theview = $lang['l_week'];
   } elseif ($rssview == "month") {
     $theview = $lang['l_month'];
   }
   

3. In phpiCalendar “rss/rss.php” add this code right below the block for processing SINGLE DAY requests.

$thisdate = time();
$i = 0;
if ($rssview == "calweek") {
  do {
    $getdate = date("Ymd", $thisdate);
    $dayofweek = strtotime ($getdate);
    $dayofweek = localizeDate ($dateFormat_day, $dayofweek);
    if (isset($master_array[($getdate)]) && sizeof($master_array[($getdate)]) > 0) {
      foreach ($master_array[("$getdate")] as $event_times) {
        foreach ($event_times as $val) {
          $event_start    = @$val["event_start"];
          $event_start    = date ($timeFormat, @strtotime ("$event_start"));
          $event_text     = stripslashes(urldecode($val["event_text"]));
          $event_text     = strip_tags($event_text, '<b><i><u>');
          $event_text     = word_wrap($event_text, 21, $tomorrows_events_lines);
          $description    = stripslashes(urldecode($val["description"]));
          $description    = strip_tags($description, '<b><i><u>');
          $rss_title              = htmlspecialchars ("$dayofweek: $event_text");
          $rss_link               = htmlspecialchars ("$default_path/day.php?getdate=$getdate&cal=$cal");
          $rss_description        = htmlspecialchars ("$dayofweek $event_start: $event_text - $description");
          $rss .= '<item>'."\n";
          $rss .= '<title>'.$rss_title.'</title>'."\n";
          $rss .= '<link>'.$rss_link.'</link>'."\n";
          $rss .= '<description>'.$rss_description.'</description>'."\n";
          $rss .= '</item>'."\n";
          $events_week++;
        }
      }
    }
    if {
      $rss .= '<item>'."\n";
      $rss .= '<title>'.$lang['l_no_events_week'].'</title>'."\n";
      $rss .= '<link>'.htmlspecialchars ("$default_path").'</link>'."\n";
      $rss .= '</item>'."\n";
    }
    $thisdate = ($thisdate + (25 * 60 * 60));
    $i++;
  } while ($i < 7);
}

4. Browse to {your phpiCalendar installation}/index.php and get the URL for your WEEKLY events. Change the last part of the URL (should be “rssview=week”) to “rssview=calweek”. Mine looks like this:

   http://saintandrewslutheran.org/calendar/rss/rss.php?cal=Public&rssview=calweek

5. Install MagpieRSS to a reasonable location.
6. Include the below code in your site. Be sure to set the correct require_once path (if you didn’t just throw MagpieRSS in the default folder like I did) and to change the URL in the call to fetch_rss to YOUR RSS feed.

<?php
require_once('magpierss/rss_fetch.inc');

$rss =
fetch_rss("http://saintandrewslutheran.org/calendar/rss/rss.php?cal=Public&rssview=calweek");
echo "<p>The next 7 days' calendar items:</p>";
$inUL = false;
$oldDate = '';
foreach($rss->items as $item) {
  $href = $item['link'];
  $title = $item['title'];
  if(stristr($title, 'PRIVATE')) { continue; }

  $date = substr($title, 0, strpos($title, ':'));
  $cleantitle = substr($title, strpos($title, ':')+1);

  if ($oldDate != $date) {
    if ($inUL) {
      echo "</ul>";
    }
    echo "<p>$date</p><ul>";
    $inUL = true;
    $oldDate = $date;
  }
  echo "<li><a href=$href>$cleantitle</a></li>";
}
echo "</ul>";
?>

7. Enjoy!
