我已经做了一个while循环来获取数据库中的所有问题和答案，但是，我无法通过使用单选按钮来选择每个问题的一个答案。
<form class ="formlayout" action = "Test.php" method = "post">
<?php
while ($row = mysqli_fetch_assoc($result)) {
$question = $row['question'];
$option1 = $row['option1'];
$option2 = $row['option2'];
$option3 = $row['option3'];
?>
<?php echo $question ?> <br>
<input type="radio" name="<?php echo $i ?>" value="$option1"><?php echo $option1 ?><br>
<input type="radio" name="<?php echo $i ?>" value="$option2"><?php echo $option2 ?><br>
<input type="radio" name="<?php echo $i ?>" value="$option3"><?php echo $option3 ?><br>
<?php echo "" ?><br>
<?php
}
?>
<input type="submit" value="Submit"/>
</form>
谢谢。
给它们起一个相同的名字:
<form class ="formlayout" action = "Test.php" method = "post">
<?php
while ($row = mysqli_fetch_assoc($result)) {
$question = $row['question'];
$option1 = $row['option1'];
$option2 = $row['option2'];
$option3 = $row['option3'];
?>
<?php echo $question ?> <br>
<input type="radio" name="YourName" value="$option1"><?php echo $option1 ?><br>
<input type="radio" name="YourName" value="$option2"><?php echo $option2 ?><br>
<input type="radio" name="YourName" value="$option3"><?php echo $option3 ?><br>
<?php echo "" ?><br>
<?php
}
?>
<input type="submit" value="Submit"/>
</form>
我认为$ I是未定义的，为什么不简单地使用一些静态字符串作为名称…例如:
<input type="radio" name="my_radio"/>
定义您的$i并将其增加到有不同组的答案，您也可以更改您的无线电名称，以便稍后轻松解析:
<form class ="formlayout" action = "Test.php" method = "post">
<?php
$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
$question = $row['question'];
$option1 = $row['option1'];
$option2 = $row['option2'];
$option3 = $row['option3'];
?>
<?php echo $question ?> <br>
<input type="radio" name="answerswer_<?php echo $i ?>" value="$option1"><?php echo $option1 ?><br>
<input type="radio" name="answerswer_<?php echo $i ?>" value="$option2"><?php echo $option2 ?><br>
<input type="radio" name="answerswer_<?php echo $i ?>" value="$option3"><?php echo $option3 ?><br>
<?php echo "" ?><br>
<?php
$i++;
}
?>
<input type="submit" value="Submit"/>
</form>
