Answer 1

您有连接错误。您的错误符合要求：selected='selected'>.$_POST['prestiti']您忘记了"

我已在下面的代码中解决了这些错误

<?php 
     if ($_POST['prestiti']){
        echo "<option value=".$_POST['prestiti']." selected='selected'>".$_POST['prestiti']."</option>";}
     else{
        echo "<option value='No' selected='selected'>No</option>";
    }
?>

Answer 2

试试这个;

if (isset($_POST['prestiti']) && $_POST['prestiti'] != ""){
   echo "<option value=".$_POST['prestiti']." selected='selected'>" . $_POST['prestiti'] ."</option>";
}else{
   echo "<option value='No' selected='selected'>No</option>";
}
