$stmt1 = $DB_con->prepare('SELECT * FROM oth_events_details
LEFT JOIN oth_event_category ON (oth_events_details.oth_evcat_id=oth_event_category.oth_evcat_id)

Answer 1

Name should be same for input field. Use following code:
<input type="checkbox" name="chk[]" value="<?php echo $row1['oth_event_det_id'];?>" id="chk[<?php echo $row1['oth_event_det_id'];?>]" />
Fees:- <?php echo $row1['oth_ev_fee'];?>
You can see name. Hopefully it will be clear enough

Answer 2

Just change the value of you checkboxes and the value it represents but keep the name same with the others, yet it should have a name with []
<input type="checkbox" id="chk<?php echo $row1['oth_event_det_id'];?>" name="chk[]" value="<?php echo $row1['oth_event_det_id'];?>">
<label for="chk<?php echo $row1['oth_event_det_id'];?>"><?php echo $row1['oth_event_det_id'];?></label>
having a name chk[] like this will send and serve as an array in your get or post-function so loop it on controller or function that will add it in the DB
upon inserting it,
$data = $_GET['chk']; //this is in array form
foreach($data as $chk){
//insert code here
}
