Answer 1

PHP

das Ersetzen:

$_POST['job-destination[$i]'] 

mit diesem:

$_POST['job-destination'][$i] 

in Ihrem HTML-Eingänge, [] verwenden wie so wird Ihre Eingabe automatisch indizieren:

HTML

<div class="form-group"> 
    <p>Destination</p> 
    <div class="radio-btn-grp"> 
    <input class="job-destination" name="job-destination[]" value="Australia" type="radio" required=""> 
    <label for="job-destination">Australia</label> 
    </div> 
    <div class="radio-btn-grp"> 
    <input class="job-destination" name="job-destination[]" value="Canada" type="radio"> 
    <label for="job-destination">Canada</label> 
    </div> 
</div> 

Sie sollten auch Ihre for-Schleife ändern Ihre $_POST['job-destination']

PHP

for ($i=0; $i <= count($_POST['job-destination']); $i++){
