我從我的數據庫中回顯單選按鈕的值，并且以這種形式（while 循環）是獲取它們的最快方法。當我這樣做時，它會看到所有單選按鈕都在同一個“組”中。如何使它具有多個“組”以便可以回答多個問題？我嘗試向它添加一個 div ，但沒有奏效。<form action="Antwoord.php" method="POST"><?php $sql = "SELECT * FROM questionlist_choice"; $result = mysqli_query($conn, $sql); if ($result->num_rows > 0) { while ($row = mysqli_fetch_assoc($result)) {$vraag = $row['Vraag'];$vraagA = $row['Vraag_keuzeA'];$vraagB = $row['Vraag_keuzeB'];$vraagC = $row['Vraag_keuzeC'];$vraagD = $row['Vraag_keuzeD'];$vraagE = $row['Vraag_keuzeE'];$vraagF = $row['Vraag_keuzeF'];echo "<div>"; echo "<br><p>$vraag</p>"; echo "<input type='radio' name='gender' value='$vraagA'> $vraagA<br>"; echo "<input type='radio' name='gender' value='$vraagB'> $vraagB<br>"; echo "<input type='radio' name='gender' value='$vraagC'> $vraagC<br>"; echo "<input type='radio' name='gender' value='$vraagD'> $vraagD<br>"; echo "<input type='radio' name='gender' value='$vraagE'> $vraagE<br>"; echo "<input type='radio' name='gender' value='$vraagF'> $vraagF<br>";echo "</div>"; }}?><input type="submit"></form>

抱歉，我不太了解您的問題，但是如果您想要GROUP他們，您需要在name標簽上添加索引，如下所示：
$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
$vraag = $row['Vraag'];
$vraagA = $row['Vraag_keuzeA'];
$vraagB = $row['Vraag_keuzeB'];
$vraagC = $row['Vraag_keuzeC'];
$vraagD = $row['Vraag_keuzeD'];
$vraagE = $row['Vraag_keuzeE'];
$vraagF = $row['Vraag_keuzeF'];
echo "<div>";
echo "<br><p>$vraag</p>";
echo "<input type='radio' name='gender[$i]' value='$vraagA'> $vraagA<br>";
echo "<input type='radio' name='gender[$i]' value='$vraagB'> $vraagB<br>";
echo "<input type='radio' name='gender[$i]' value='$vraagC'> $vraagC<br>";
echo "<input type='radio' name='gender[$i]' value='$vraagD'> $vraagD<br>";
echo "<input type='radio' name='gender[$i]' value='$vraagE'> $vraagE<br>";
echo "<input type='radio' name='gender[$i]' value='$vraagF'> $vraagF<br>";
echo "</div>";
$i++;
}
我$i用作索引，我認為如果您使用它會更好，for loop因為它已經$key有價值，我認為使用它while是一個壞習慣。
