php单选按钮提交MD阵列

Question

我无法让提交按钮工作。我对php很陌生，仅仅几个星期。目前，我们的目标只是让表单提交到同一页面，以便用户可以看到他/她点击了什么。我使用多维数组和foreach循环来显示问题和选择。只是不能得到任何提交工作。任何提示或技巧将不胜感激。

<form method="post" action=""> 

    <?php 
     foreach($q_and_ans as $i => $q_and_an):?> 

      <p><?php echo $q_and_an['question'];?></p> 
      <?php foreach($q_and_an['ans'] as $a => $ans): ?> 
      <input type="radio" value="<?=$a?>" name="question[<?=$i?>]" > 
      <?php echo $ans;?><br> 
      <?php endforeach;?> 
    <?php endforeach;?> 

    <input type="submit" name="submit" id="submit" value="Submit"> 
</form> 
<?php 
if(isset($_POST['submit'])){ 

if (isset($_POST['question[0]'])){ 
$yourchoice0 = $POST['question[0]']; 
echo ("You selected ".$yourchoice0); 
} 
else{ 
    echo ("select an option");

if (isset($_POST['question[1]'])){ 
$yourchoice1 = $POST['question[1]'];

这应该是你的问题更好的解决方案：

<?php 
// Sample Data, Replace with Yours 
$mcq = array(
    array('q' => 'question1?', 'opts' => ['opt1', 'opt2', 'opt3', 'opt4'], 'ans' => 0), 
    array('q' => 'question2?', 'opts' => ['opt1', 'opt2', 'opt3', 'opt4'], 'ans' => 1), 
    array('q' => 'question3?', 'opts' => ['opt1', 'opt2', 'opt3', 'opt4'], 'ans' => 2), 
    array('q' => 'question4?', 'opts' => ['opt1', 'opt2', 'opt3', 'opt4'], 'ans' => 3)); 
?> 
<form method="post" action=""> 
    <?php 
    $q_count = 0; 
    foreach($mcq as $q) { 
     $opt_count = 0; 
    ?> 
     <p> 
     <?php echo 'Q.'.($q_count + 1).' '.$q['q'].'<br />'; 
     foreach($q['opts'] as $opt) { 
     ?> 
      <input type="radio" id="<?php echo 'opt-'.$opt_count; ?>" value="<?php echo $opt; ?>" 
       name="<?php echo 'q-'.$q_count; ?>"> 
      <label for="<?php echo 'opt-'.$opt_count; ?>"><?php echo $opt; ?></label><br /> 
    <?php 
      $opt_count++; 
     } 
     unset($opt); 
     $q_count++; 
    } 
    unset($q); 
    ?> 
    </p> 
    <input type="submit" name="submit" value="Submit"> 
</form> 

<?php 
if(isset($_POST['submit'])) { 
    echo '<p>Your answers are:<br />'; 
    $count = 0; 
    foreach($mcq as $q) { 
     echo 'Q.'.($count + 1).':: Your answer: '; 
     if(isset($_POST['q-'.$count])) 
      echo $_POST['q-'.$count]; 
     else 
      echo 'Not Selected'; 
     echo ', Correct Answer: '.$q['opts'][$q['ans']].'<br />'; 
     $count++; 
    } 
    unset($q); 
    echo '</p>'; 
} 
?> 

Answer 2

尝试如下更改代码：

if (isset($_POST["question"][0])){ //<------------ change here 
$yourchoice0 = $_POST["question"][0];//<------------ change here 
echo ("You selected ".$yourchoice0); 
} 
else{ 
    echo ("select an option"); 
} 

if (isset($_POST["question"][1])){ 
$yourchoice1 = $_POST['question'][1]; 
echo ("You selected ".$yourchoice1); 
} 
else{ 
echo ("select an option"); 
} .....
