How do i keep the selected value in the dropdown menu when the form is submitted?

How do i keep the selected value in select name="betalingsmethode" class="dropdown" after the form is submitted. What happens now is when I submit the form the drop-down refreshes and shows Visa again. but I want to keep the selected value in there, the one the user selected.

I tried the same as I did with the checkboxes: 

?php if(isset($_POST['visa'])) echo "selected='selected'"; ?

But it doesn't work.

Instead of :

if(isset($_POST['visa'])) echo "selected='selected'";

try :

if($_POST['betalingsmethode'] == 'visa') echo "selected='selected'";

And so on for the others options.

You have "selected" attribute inside the option

<select name="betalingsmethode" class="dropdown">
  <option value="visa"       name="visa" <?php 
  if(isset($_POST['betalingsmethode']) && $_POST['betalingsmethode']=='visa') echo "selected='selected'"; ?>>Visa             </option>
  <option value="mastercard" name="mastercard" <?php 
  if(isset($_POST['betalingsmethode']) && $_POST['betalingsmethode']=='mastercard') echo "selected='selected'"; ?>>Mastercard </option>
  <option value="paypal"     name="paypal" <?php 
  if(isset($_POST['betalingsmethode']) && $_POST['betalingsmethode']=='paypal') echo "selected='selected'"; ?>>PayPal         </option>
  <option value="ideal"      name="ideal" <?php 
  if(isset($_POST['betalingsmethode']) && $_POST['betalingsmethode']=='ideal') echo "selected='selected'"; ?>>Ideal           </option>
 </select>
