Question

我在PHP

中有两个带单选按钮的问题（每个问题有4个收音机）

但所有8个单选按钮都有单一检查，但应该是4-4个单选按钮。

我的代码：

<form method="post" enctype="multipart/form-data" class="form-horizontal">

    <?php


    $lstmt = $user->runQuery("SELECT * FROM mcq WHERE LRN=:lrn ORDER BY Sr ASC ");
    $lstmt->bindparam(":lrn",$id);
    $lstmt->execute();

    if($lstmt->rowCount() > 0)
    {
    $i=0;
        while($lrow=$lstmt->fetch(PDO::FETCH_ASSOC))
        {
            extract($lrow);
            $i++;

?>    
    <div>
    <h1><?php echo $i; ?>)&nbsp;<?php echo $Question; ?></h1></br>
    <h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio" value="<?php echo $Oa; ?>">&nbsp;&nbsp;A) <?php echo $Oa; ?></h2>
    <h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio" value="<?php echo $Ob; ?>">&nbsp;&nbsp;B) <?php echo $Ob; ?></h2>
    <h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio" value="<?php echo $Oc; ?>">&nbsp;&nbsp;C) <?php echo $Oc; ?></h2>
    <h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio" value="<?php echo $Od; ?>">&nbsp;&nbsp;D) <?php echo $Od; ?></h2>
    </div>
    <hr></br></br>
    <?php
    }
    }
    ?>
    <button class="btn btn-large btn-primary" type="submit" name="btn-submit">Submit</button>
</form>
<?php
}
if(isset($_POST['btn-submit']))
{
    echo $ufname = trim($_POST['radio']);
}
?>

更新您的无线电输入名称属性，

<div>
<h1><?php echo $i; ?>)&nbsp;<?php echo $Question; ?></h1></br>
<h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio<?php echo $i; ?>?>" value="<?php echo $Oa; ?>">&nbsp;&nbsp;A) <?php echo $Oa; ?></h2>
<h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio<?php echo $i; ?>" value="<?php echo $Ob; ?>">&nbsp;&nbsp;B) <?php echo $Ob; ?></h2>
<h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio<?php echo $i; ?>" value="<?php echo $Oc; ?>">&nbsp;&nbsp;C) <?php echo $Oc; ?></h2>
<h2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="radio" name="radio<?php echo $i; ?>" value="<?php echo $Od; ?>">&nbsp;&nbsp;D) <?php echo $Od; ?></h2>
</div>

提交：

<?php
}
$count = $i;
for($j = 1; $j <= $count; $j++){ if(isset($_POST['btn-submit'])) { 
echo $ufname = trim($_POST['radio'.$j]); 
}
}
?>

它肯定会解决你的问题，

单选按钮中的选择被替换为两个div
