Creating a Calendar Template

By creating a calendar template you have 100% control over the design of your calendar. Using the string method, each component of your calendar will be placed within a pair of pseudo-variables as shown here:

$prefs['template'] = '

{table_open}<table border="0" cellpadding="0" cellspacing="0">{/table_open}

{heading_row_start}<tr>{/heading_row_start}

{heading_previous_cell}<th><a href="{previous_url}">&lt;&lt;</a></th>{/heading_previous_cell}
{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
{heading_next_cell}<th><a href="{next_url}">&gt;&gt;</a></th>{/heading_next_cell}

{heading_row_end}</tr>{/heading_row_end}

{week_row_start}<tr>{/week_row_start}
{week_day_cell}<td>{week_day}</td>{/week_day_cell}
{week_row_end}</tr>{/week_row_end}

{cal_row_start}<tr>{/cal_row_start}
{cal_cell_start}<td>{/cal_cell_start}
{cal_cell_start_today}<td>{/cal_cell_start_today}
{cal_cell_start_other}<td class="other-month">{/cal_cell_start_other}

{cal_cell_content}<a href="{content}">{day}</a>{/cal_cell_content}
{cal_cell_content_today}<div class="highlight"><a href="{content}">{day}</a></div>{/cal_cell_content_today}

{cal_cell_no_content}{day}{/cal_cell_no_content}
{cal_cell_no_content_today}<div class="highlight">{day}</div>{/cal_cell_no_content_today}

{cal_cell_blank}&nbsp;{/cal_cell_blank}

{cal_cell_other}{day}{/cal_cel_other}

{cal_cell_end}</td>{/cal_cell_end}
{cal_cell_end_today}</td>{/cal_cell_end_today}
{cal_cell_end_other}</td>{/cal_cell_end_other}
{cal_row_end}</tr>{/cal_row_end}

{table_close}</table>{/table_close}
';

$this->load->library('calendar', $prefs);

echo $this->calendar->generate();

Using the array method, you will pass key => value pairs. You can pass as many or as few values as you’d like. Omitted keys will use the default values inherited in the calendar class.

Example:

$prefs['template'] = array(
'table_open' => '<table class="calendar">',
'cal_cell_start' => '<td class="day">',
'cal_cell_start_today' => '<td class="today">'
);

$this->load->library('calendar', $prefs);

echo $this->calendar->generate();
