Codeigniter disable calendar date after 5 bookings - php

Question

I have calendar whose dates are booked and saved in database. I am trying to pull the bookings from database and show then under corresponding date. Everything is working fine, except the thing, I want the date to be just text instead of link when there are more than 5 events to that date.
I am aware of the calendar template no content cell and content cells. But i want the date to have no link when it has more than 5 events attached to it.
My Model:
public function bookingcalender($year=null,$month=null)
{
if(!$year)
{
$y = date('Y');
}
else
{
$y = $year;
}
if(!$month)
{
$m = date('m');
}
else
{
$m = $month;
}
$this->config = array(
'show_next_prev' => TRUE,
'next_prev_url' => 'http://joshuaflinn.com/CI/booking/show',
'template' => '{table_open}<table class="availability-calendar">{/table_open}
{heading_row_start}<tr class="toolbar">{/heading_row_start}
{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
{heading_previous_cell}<th><</th>{/heading_previous_cell}
{heading_next_cell}<th>></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}{day}<span class="date-data">{content}</span>{/cal_cell_content}
{cal_cell_content_today}<div class="highlight">{day}</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} {/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}'
);
$this->load->library('calendar',$this->config);
$conf_data = $this->get_booked_dates($year,$month);
return $this->calendar->generate($year,$month,$conf_data);
}
public function get_booked_dates($year,$month)
{
$query = $this->db->select('client_name,booking_date')->from('bookings')->like('booking_date',"$year-$month")->get();
$cal_data = array();
foreach($query->result() as $row)
{
$dt = explode("-", $row->booking_date);
$dt = $dt[2];
$k = ($dt >= 10 ? substr($row->booking_date, 8,2) : substr($row->booking_date, 9,1));
if( #$cal_data[$k] == '' )
{
$cal_data[$k] = $row->client_name;
}
else
{
$cal_data[$k] .= ','.$row->client_name;
}
}
return $cal_data;
}

The options you have are limited since Codeigniters Calendar Library only have the two pseudo variables cal_cell_no_content and cal_cell_contentin the template to play with in terms of what content you want to display.
A quick look behind the door reveals that the library uses isset() to determine which of the two pseudo variables to use.
And it calls str_replace {content} before {day} that opens up for a somewhat hacky solution:
public function bookingcalender($year=null,$month=null)
{
if(!$year)
{
$y = date('Y');
}
else
{
$y = $year;
}
if(!$month)
{
$m = date('m');
}
else
{
$m = $month;
}
$this->config = array(
'show_next_prev' => TRUE,
'next_prev_url' => 'http://joshuaflinn.com/CI/booking/show',
'template' => '{table_open}<table class="availability-calendar">{/table_open}
{heading_row_start}<tr class="toolbar">{/heading_row_start}
{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
{heading_previous_cell}<th><</th>{/heading_previous_cell}
{heading_next_cell}<th>></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}{content}{/cal_cell_content}
{cal_cell_content_today}<div class="highlight">{content}</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} {/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}'
);
$this->load->library('calendar',$this->config);
$conf_data = $this->get_booked_dates($year,$month);
return $this->calendar->generate($year,$month,$conf_data);
}
public function get_booked_dates($year,$month)
{
$query = $this->db->select('client_name,booking_date')->from('bookings')->like('booking_date',"$year-$month")->get();
$cal_data = array();
foreach($query->result() as $row)
{
$dt = explode("-", $row->booking_date);
$k = intval($dt[2]); // MAKE INTEGER OF DAY NUMBER
if( #$cal_data[$k] == '' )
{
$cal_data[$k] = $row->client_name;
}
else
{
$cal_data[$k] .= ','.$row->client_name;
}
}
// LOOP THROUGH EACH DAY TO FIND THOSE WITH MORE THAN 5 EVENTS
foreach($cal_data as $key=>$val){
// COUNT THE NUMBER OF COMMAS THAT OCCUR IN STRING
$count = strlen($val) - strlen(str_replace(',','',$val));
if($count > 4){ // IF MORE THAN 4 COMMAS (> 5 EVENTS) THEN NO LINK...
$cal_data[$key] = '{day}<span class="date-data">'.$val.'</span>';
} else { // LINKED DAY
$cal_data[$key] = '{day}<span class="date-data">'.$val.'</span>';
}
}
return $cal_data;
}
Note: that I have changed two rows in the template: {cal_cell_content}{content}{/cal_cell_content} and {cal_cell_content_today}<div class="highlight">{content}</div>{/cal_cell_content_today}
You now only need to set {content} since {day} is specified inside the content also containing the html returned from the query.
Update: I have now tested the solution and it seems to work fine!
You have to manipulate or extend the Calendar library if you need a more flexible solution and if you don't want to mix template html in the content returned from your query.
