Answer 1

Your input should be

<input type="hidden" id="car" name="vehicle[]" value="car" />
<input type="hidden" id="bike" name="vehicle[]" value="bike" />
<input type="hidden" id="truck" name="vehicle[]" value="truck" />
<input type="hidden" id="cycle" name="vehicle[]" value="cycle" />
<input type="hidden" id="train" name="vehicle[]" value="train" />

then in server side

<?php
$vehicles=$_POST["vehicle"];
foreach($vehicles as $vehicle){
 // Do your sfuff here
}
?>

If using ajax this may help you

$.ajax({
 url: "index.php",
 type: 'POST',
 data: form_data,
 dataType:"json",
 success: function(data) {
 alert(data[0]);
 }

Answer 2

First

• Id must be unique
• so if you want to use same id then use class instead

Second

• name="themes" should be name="themes[]"
