Question

我想通过从数据库中提取问题及其选项来生成问题文件。存在3个问题，其中15个选项，5对于每个问题，我只能从15个中选择一个选项。下面的代码和图像输出也

<?php
for($i=1;$i<=3;$i++)
    $s = "select OPTION1,OPTION2,OPTION3,OPTION4,OPTION5,CORRECT_ANSWER from T_QUESTIONS where QUES_NO='$i'";
          $result=mysqli_query($conn,$s);
            if(!mysqli_query($conn,$s))
                echo mysqli_error($conn);
            else
                    while ($row = $result->fetch_assoc()) {?>

                            <form action = "CHECK.php" method="POST">
                        <input type="radio" name="choice" value="<?php $row['OPTION1']; ?>" /> <?php echo $row['OPTION1']."<br>"; ?>
                        <input type="radio" name="choice" value="<?php $row['OPTION2']; ?>" /> <?php echo $row['OPTION2']."<br>"; ?>
                        <input type="radio" name="choice" value="<?php $row['OPTION3']; ?>" /> <?php echo $row['OPTION3']."<br>"; ?>
                        <input type="radio" name="choice" value="<?php $row['OPTION4']; ?>" /> <?php echo $row['OPTION4']."<br>"; ?>
                        <input type="radio" name="choice" value="<?php $row['OPTION5']; ?>" /> <?php echo $row['OPTION5']."<br>"; ?>
                        <br>


        <?php         
        }       
        }

        ?>

Answer 1

<form action = "CHECK.php" method="POST">
<?php
for($i=1;$i<=3;$i++) { ?>
    <label>Question</label>
    <input type="radio" name="choice<?php echo $i?>" value="a" /> 1
    <input type="radio" name="choice<?php echo $i?>" value="b" /> 1
    <input type="radio" name="choice<?php echo $i?>" value="c" /> 1
    <input type="radio" name="choice<?php echo $i?>" value="d" /> 1
    <input type="radio" name="choice<?php echo $i?>" value="e" /> 1
    <br>
<?php }  ?>
</form>

Answer 2

这是您的操作方法。您必须将<form>标记放在循环之外，并且必须为name按钮设置不同的radio属性：

    <form action = "CHECK.php" method="POST">
    <?php
    for($i=1;$i<=3;$i++)
        $s = "select OPTION1,OPTION2,OPTION3,OPTION4,OPTION5,CORRECT_ANSWER from T_QUESTIONS where QUES_NO='$i'";
        $result=mysqli_query($conn,$s);
        if(!mysqli_query($conn,$s))
            echo mysqli_error($conn);
        else
                while ($row = $result->fetch_assoc()) {?>


                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION1']; ?>" /> <?php echo $row['OPTION1']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION2']; ?>" /> <?php echo $row['OPTION2']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION3']; ?>" /> <?php echo $row['OPTION3']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION4']; ?>" /> <?php echo $row['OPTION4']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION5']; ?>" /> <?php echo $row['OPTION5']."<br>"; ?>
                    <br>


    <?php         
    }       
    }

    ?>
    </form>

Answer 3

<?php   for($i=1;$i<=3;$i++)
            {?>
<form action = "CHECK.php" method="POST">
<?php

        $s = "select OPTION1,OPTION2,OPTION3,OPTION4,OPTION5,CORRECT_ANSWER from T_QUESTIONS where QUES_NO='$i'";
        $result=mysqli_query($conn,$s);
        if(!mysqli_query($conn,$s))
            echo mysqli_error($conn);
        else
                while ($row = $result->fetch_assoc()) {?>


                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION1']; ?>" /> <?php echo $row['OPTION1']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION2']; ?>" /> <?php echo $row['OPTION2']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION3']; ?>" /> <?php echo $row['OPTION3']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION4']; ?>" /> <?php echo $row['OPTION4']."<br>"; ?>
                    <input type="radio" name="choice<?php echo $i; ?>" value="<?php echo $row['OPTION5']; ?>" /> <?php echo $row['OPTION5']."<br>"; ?>
                    <br>


    <?php         
    }       
    }
    ?>
    </form>
