插入多个数组到数据库

我正在创建一个多选题测验，我不知道如何将多个数组插入数据库。我可以使用array_combine插入前两个数组，但不能在第3，第4，第5和第6个数组中插入。我可以将问题和答案，但不是选项A，B，C和D插入多个数组到数据库

我试图做类似

的foreach（array_combine（$ _ POST [ 'inQuestion']，$ _ POST [ 'inAnswer']，$ _POST ['inA']，$ _POST ['inB']，$ _POST ['inC']，$ _POST ['inD']）作为$ question => $ answer => $ A => $ B => $ C => $ D）{

请帮忙。这是我的代码。

<?php 
    if(isset($_POST['btnCreate'])) { 

     $inQuestion = array($_POST['inQuestion']); 
     $inAnswer = array($_POST['inAnswer']); 
     $inA = array($_POST['inA']); 
     $inB = array($_POST['inB']); 
     $inC = array($_POST['inC']); 
     $inD = array($_POST['inD']); 
     $inLesson = $_POST['inLesson']; 
     $inQuizNo = $_POST['inQuizNo']; 

     $sql = "SELECT * FROM lessons WHERE title='$inLesson'"; 
     $query = mysql_query ($sql); 
     $row = mysql_fetch_assoc($query); 

     $lessonID = $row['lessonID']; 

     foreach(array_combine($_POST['inQuestion'], $_POST['inAnswer']) as $question => $answer) { 

      $sql = "INSERT INTO `test` (question, answer, A, B, C, D, lessonID, quizNo) VALUES ('$question', '$answer', '$A', '$B', '$C', '$D', '$lessonID', $inQuizNo)"; 
      $query = mysql_query($sql); 
     } 

    }

给你完整的代码，包括HTML代码。以便我们明白你想要什么 –

这些数组的值类型是什么？为什么你有一个数组与其中的一个项目？ – Othman

你介意给我们更多关于你想要达到什么的信息吗？ – Othman

从我的理解，你想插入multible行到你的数据库。

首先，当你在HTML表单使用[]您不必将其声明为一个数组中php

其次，每个问题都会有一个疑问名字，答案，A，B，C，d

当您尝试创建HTML表单时，您可以使用此格式来跟踪question_id或编号。

<label>Question</label><input type='text' id='textbox1' name='inQuestion[1]' class="form-control">

然后你就可以检索该项目作为$_POST['inQuestion'][1]

例如，如果您需要在您的测试页10个问题，你可以做这样的：

<?php for($i = 0; $i <= 10; $i++) : ?> 
<form method="post"> 

    <div class="col-md-10"> 
     <label>Question</label><input type='text' id='textbox1' name='inQuestion[<?=$i;?>]' class="form-control"> 
    </div> 

    <div class="col-md-2"> 
     <label>Answer</label><input type='text' id='textbox1' name='inAnswer[<?=$i;?>]' class="form-control"> 
     <br> 
    </div> 


    <div class="col-md-3"> 
     <label>A</label><input type='text' id='textbox1' name='inA[<?=$i;?>]' class="form-control"> 
    </div> 
    <div class="col-md-3"> 
     <label>B</label><input type='text' id='textbox1' name='inB[<?=$i;?>]' class="form-control"> 
    </div> 
    <div class="col-md-3"> 
     <label>C</label><input type='text' id='textbox1' name='inC[<?=$i;?>]' class="form-control"> 
    </div> 
    <div class="col-md-3"> 
     <label>D</label><input type='text' id='textbox1' name='inD[<?=$i;?>]' class="form-control"> 
     <br><br> 
    </div> 


    <input type="submit" value="go"> 

</form> 

<?php endfor; ?>

而且，为什么你把答案A，B，C，D的内容放到数组中，而你的数据库中有列。在查询中也使用这些变量。

$inA = $_POST['inA']; 
$inB = $_POST['inB']; 
$inC = $_POST['inC']; 
$inD = $_POST['inD'];

最后我们试着现在插入你的值。

if($_POST['btnCreate']){ 

    // The form has been posted! 

    $inLesson = $_POST['inLesson']; 
    $inQuizNo = $_POST['inQuizNo']; 

    $questionsCount = count($_POST['inQuestion']); 

    $items = array(); 

    // Since we should have the same size of arrays. 
    // Also the empty validation has been handled before this step! 
    for($i = 0; $i < $questionsCount; $i++){ 
      $temp = array(); 
     $temp['inQuestion'] = $_POST['inQuestion'][$i]; 
     $temp['inAnswer']  = $_POST['inAnswer'][$i]; 
     $temp['inA']   = $_POST['inA'][$i]; 
     $temp['inB']   = $_POST['inB'][$i]; 
     $temp['inC']   = $_POST['inC'][$i]; 
     $temp['inD']   = $_POST['inD'][$i]; 
      $items[] = $temp; 
    } 


    // Now items should have an array of all questions. 

    foreach($items as $item){ 

     $SQL = 'INSERT INTO `test` (question, answer, A, B, C, D, lessonID, quizNo) VALUES (
                          "'.$item['inQuestion'].'", 
                          "'.$item['inAnswer'].'", 
                          "'.$item['inA'].'", 
                          "'.$item['inB'].'", 
                          "'.$item['inC'].'", 
                          "'.$item['inD'].'", 
                          "'.$inLesson.'", 
                          "'.$inQuizNo.'")'; 

     $query = mysql_query($SQL); 
    } // End Foreach 
}

它给了我一个错误。这条线上的未定义变量1 >> for（$ i = 0; $ i <$$ questionsCount; $ i ++）{ – user2825914

我修正了for循环，现在可以试试了。 – Othman

我终于得到了我的答案先生。你是非常大的帮助。谢谢：） – user2825914

尝试这个

<?php 
    if(isset($_POST['btnCreate'])) { 

     $inQuestion = array($_POST['inQuestion']); 
     $inAnswer = array($_POST['inAnswer']); 
     $inA = $_POST['inA'] ? $_POST['inA'] : null; 
     $inB = $_POST['inB'] ? $_POST['inB'] : null; 
     $inC = $_POST['inC'] ? $_POST['inC'] : null; 
     $inD = $_POST['inD'] ? $_POST['inD'] : null; 
     $inLesson = $_POST['inLesson']; 
     $inQuizNo = $_POST['inQuizNo']; 

     $sql = "SELECT * FROM lessons WHERE title='$inLesson'"; 
     $query = mysql_query ($sql); 
     $row = mysql_fetch_assoc($query); 

     $lessonID = $row['lessonID']; 

      $sql = "INSERT INTO `test` (question, answer, A, B, C, D, lessonID, quizNo) VALUES ('$question', '$answer', '$inA', '$inB', '$inC', '$inD', '$lessonID', $inQuizNo)";

它仍然没有工作先生。它给了我一个通知：“在sql语句中对数组进行字符串转换”。 – user2825914

再次尝试我的答案，我做了一些编辑到您的HTML和你的PHP代码 –

，而不是发布一个详细的解决方案，玩如何插入多行得到一些想法

喜欢的东西：

$_POST['inQuestion'] = array(
    'q1','q2','q3' // from input array name 'inQuestion[]' 
); 

$_POST['inAnswer'] = array(
    'a1','a2','a3' // from input array name 'inAnswer[]' 
); 

$_POST['other'] = 'sunshine'; 

$_POST['yet_another'] = 'nice weather'; 

foreach($_POST['inQuestion'] as $k => $v){ 
$inserts[] = "(".$v.",".$_POST['inAnswer'][$k].",".$_POST['other'].",".$_POST['yet_another'].")"; 
} 

echo "INSERT INTO table col_1, col_2, col_3, col_4 VALUES ".implode(',',$inserts).""; 

// INSERT INTO table col_1, col_2, col_3, col_4 VALUES (q1,a1,sunshine,nice weather),(q2,a2,sunshine,nice weather),(q3,a3,sunshine,nice weather)
