我在PHP

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']); 
} 
?>

更新您的无线输入name属性就这样，

<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> 

以及提交：

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

它一定会解决你的问题，
