echo "selected size".$selected;

Answer 1

只要将所有内容放在一个文件中:

  <form id="s" method="post">
   <select name="size">
   <option value="small">Small</option>
    <option value="medium">Medium</option>
    <option value="large">Large</option>
  </select> 
<input type="submit" name="Submit" value="Send">
</form>

<?php
if(isset($_POST['size'])) {
  echo "selected size: ".htmlspecialchars($_POST['size']);
}
?>
