這是我從中得到語法錯誤的代碼。PHP - Post語法錯誤

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

<？PHP的 \t \t \t \t如果（$ _POST [ 'prestiti']）{ \t \t \t \t \t回聲「<選項值=」。$ _ POST [ 'prestiti']。」選擇\t = '選擇'> $ _ POST [ 'prestiti']「;} \t \t \t \t \t否則{ \t \t \t \t \t echo「」;} \t \t？> –

固定代碼這些錯誤嘗試這樣;

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>"; 
}

你有連接錯誤。你的錯誤是在行：selected='selected'>.$_POST['prestiti']你忘了"

我在下面

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