Add events to Specific date Calendar Class
Category:Core | Category:Core::Community | Category:Core::Calendar
With this small modification on the file system/libraries/Calendar.php, You will be able to add events on a Specific date in the Calendar Class
example:
[code] $data = array(
//year
'2007' => array(
//month
'08' => array(
//day
3 => 'http://example.com/news/article/2006/03/'
)
),
//year
'2008' => array(
//month
'01' => array(
//day
8 => 'http://example.com/news/article/2006/03/'
)
)
);
echo $this->calendar->generate('','',$data); [/code]
if you have your own modifications on the file system/libraries/Calendar.php you can just look for this part : [code] if (isset($data[$day])) { // Cells with content $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_content_today'] : $this->temp['cal_cell_content']; $out .= str_replace('{day}', $day, str_replace('{content}', $data[$day], $temp)); } else { // Cells with no content $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_no_content_today'] : $this->temp['cal_cell_no_content']; $out .= str_replace('{day}', $day, $temp); } [/code]
and Replace it with : [code] if (isset($data[$year][$month][$day])) { // Cells with content $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_content_today'] : $this->temp['cal_cell_content']; $out .= str_replace('{day}', $day, str_replace('{content}', $data[$year][$month][$day], $temp)); } else { // Cells with no content $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_no_content_today'] : $this->temp['cal_cell_no_content']; $out .= str_replace('{day}', $day, $temp); } [/code]
or you can just replace whats in the file system/libraries/Calendar.php with this :
