【问题描述】：

每个问题都有 3 个答案，在数据库中分配的分数为 0、1 或 2。

如何保存每个带有问题 ID 的答案和带有名称和电子邮件的答案 ID？使用此脚本显示的数据库中的问题行中大约有 50 个问题：

<?php
include "config.php";
$db = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
// Testar uppkoppling:
if (mysqli_connect_errno()){
// Databaskoppling error
 exit("Couldn't connect to the database: ".mysqli_connect_error());
}
$result = mysqli_query($db,"SELECT * FROM que");

echo '<form action="taemot.php" method="post" id="MyForm">';
while($row = mysqli_fetch_array($result)) {
echo '' . $row['que_question'] . '
<input type="radio" name="' . $row['que_answer0'] . '" value="' . $row['que_answer0'] . '">
<input type="radio" name="' . $row['que_answer1'] . '" value="' . $row['que_answer1'] . '">
<input type="radio" name="' . $row['que_answer2'] . '" value="' . $row['que_answer2'] . '"><br>';

}
echo '  <input type="text" name="name" value="Namn"><br>
       <input type="text" name = "email" value="Epostadress"><br>
       <input type="submit" value="Submit"> </form>';

?>

taemot.php

 <? 
$name=$_POST['name']; 
$email=$_POST['email'];

mysql_connect("XXXX", "XXXX", "XXXX") 
or die(mysql_error()); mysql_select_db("database") or die(mysql_error()); 

mysql_query("INSERT INTO `data` VALUES ('$name', '$email')"); 

Print "Your information has been successfully added to the database."; ?>

标签： php mysql forms http-post

【解决方案1】：

尝试输入名称为数组

// Assign $i to define which question number is on
<input type="radio" name="ans[$i]" value="'. $row['que_answer0'] .'">
<input type="radio" name="ans[$i]" value="'. $row['que_answer1'] .'">
<input type="radio" name="ans[$i]" value="'. $row['que_answer2'] .'">
$i++;

对于taemont.php

$aryAns = $_POST['ans'];
foreach( $aryAns AS $key => $value ) { //$key is the question number, $value is the question answers
  mysql_query("INSERT INTO data ....");
}

【解决方案2】：

使用此解决方案，数据库中的 $key 行发布值 $i 而不是问题 ID？这个解决方案如何处理多个问题，因为在以下情况下大约有 50 个问题：

echo '' . $row['que_question'] . '

目前 50 个问题中只有 1 个值是可点击的。

看这张图就明白了：http://s29.postimg.org/d4llvjajr/questions.jpg

 $result = mysqli_query($db,"SELECT * FROM que");

 echo '<form action="taemot.php" method="post" id="MyForm">';
 while($row = mysqli_fetch_array($result)) {
  echo '' . $row['que_question'] . '
 <input type="radio" name="ans[$i]" value="'. $row['que_answer0'] .'">
 <input type="radio" name="ans[$i]" value="'. $row['que_answer1'] .'">
 <input type="radio" name="ans[$i]" value="'. $row['que_answer2'] .'">
 ';$i++;

  }
   echo '   <input type="text" name="name" value="Namn"><br>
     <input type="text" name = "email" value="Epostadress"><br>
     <input type="submit" value="Submit"> </form>';

taemot.php：

$aryAns = $_POST['ans'];
foreach( $aryAns AS $key => $value ) { //$key is the question number, $value is the question answers
mysql_query("INSERT INTO `data` VALUES ('$name', '$email', '$key', '$value')");
}  

Print "Your information has been successfully added to the database."; ?>
