Question

I am facing problem in getting more than 1 result on event calendar.

I have more than 1 exam on same day ..which i need to display.. but whats going is that, it is showing only the 1 result of same day..

my query is fetching all exams of same day but not displaying it on calendar.

My Code:

<?php
class Mycal_model extends CI_Model {

var $conf;
function Mycal_model(){
    //parent::CI_Model();

    $this->conf = array(
                    'start_day' => 'monday',
                    'show_next_prev' =>true,
                    'next_prev_url' => base_url().'mycal/display',
                    'day_type' =>'short');

    $this->conf['template'] = '

                            {table_open}<table border="1" cellpadding="0" cellspacing="0" class="calendar">{/table_open}

                            {heading_row_start}<tr>{/heading_row_start}

                                {heading_next_cell}<th><a href="{next_url}"><span class="caret right"></span></a></th>{/heading_next_cell}

}
}

My result:

stdClass Object ( [ee_exam_date] => 2017-12-21 [ee_sname] => DNB CET SS ) stdClass Object ( [ee_exam_date] => 2017-12-03 [ee_sname] => IIFT ) stdClass Object ( [ee_exam_date] => 2017-12-17 [ee_sname] => SNAP ) stdClass Object ( [ee_exam_date] => 2017-12-21 [ee_sname] => IBSAT ) stdClass Object ( [ee_exam_date] => 2017-12-21 [ee_sname] => FMGE ) stdClass Object ( [ee_exam_date] => 2017-12-10 [ee_sname] => Maha TAIT ) stdClass Object ( [ee_exam_date] => 2017-12-10 [ee_sname] => C-CAT ) stdClass Object ( [ee_exam_date] => 2017-12-17 [ee_sname] => CPT EXAMINATION )

Edit cal_data variable with conditional like this :

...
function get_calendar_data($year, $month){
    $query = $this->db->select('ee_exam_date,ee_sname')->from('vm_entrance_exams')->like('ee_exam_date',"$year-$month",'after')->get();

    $cal_data = array();

     foreach($query->result() as $row){

        if (array_key_exists(substr($row->ee_exam_date,8,2), $cal_data)) {

            $cal_data[substr($row->ee_exam_date,8,2)] = $cal_data[substr($row->ee_exam_date,8,2)] . ' ' . substr($row->ee_sname,0,50); // this will just prepend current event with previous event

        } else {

            $cal_data[substr($row->ee_exam_date,8,2)] = substr($row->ee_sname,0,50);

        }
     }

     return $cal_data;

}
