从页面上的下拉选择的php中检索post值

Question

I have a drop down select inside of a form on my page nice.php which is submitted using a button

<form action="nice.php" method="post">
<select name="CarList">
<option value="0"> - Select Car - </option>
<option value="AM">Aston Martin</option>
<option value="KG">Koenigsegg</option>
<option value="MB">Mercedes Benz</option>
</select>

<input type="submit">
</form>

After making a selection is it possible to submit the form, reload the same page however with the value from the dropdown into a php variable $SelectedCar?

Answer 1

if(!empty($_POST['CarList'])){
    $SelectedCar = $_POST['CarList'];
    echo $SelectedCar;
}else{
    echo '<p>No Selection has been made and submitted yet</p>';
}
