PHP插入数据库

Question

大家好，我正在尝试将一些复选框插入数据库，我很确定我的代码是正确的，但是我一直收到错误 ERROR INSERTING: Column count doesn't match value count at row 1

基本上我将每个复选框添加到数据库中的不同列

这是我的代码

    $idextra=$_POST['extras'];
    $arr_num=count($idextra);
    $i=0;
    while ($i < $arr_num)
   {

    $qu="INSERT INTO bs_reservations (deodoriser,carpet,carpetrepair,furniture,tabs,urine) VALUES ('$idextra[$i]')";
    $res=mysql_query($qu) or die('ERROR INSERTING: '.mysql_error());
      $i++;
    }

大家好，这里是我的复选框和联系表单的 HTML。

这是我插入数据库的完整 php 代码

`$idextra=$_POST['extras']; $arr_num=count($idextra); $i=0; 而 ($i

$qu="INSERT INTO bs_reservations (deodoriser,carpet,carpetrepair,furniture,tabs,urine) VALUES ('{$idextra[1]}','{$idextra[2]}','{$idextra[3]}','{$idextra[4]}','{$idextra[5]}','{$idextra[6]}')";
$res=mysql_query($qu) or die('ERROR INSERTING: '.mysql_error());
  $i++;
}


$q="INSERT INTO bs_reservations (dateCreated, name, email, phone, comments,status,eventID, qty,dropoff) VALUES (NOW(),'".$name."','".$email."','".$phone."','".$comments."','2','".$eventID."','".$qty."','".$dropoff."')";
$res=mysql_query($q) or die("error!");
$orderID=mysql_insert_id();`

我基本上想获取用户选择的所有输入并将它们插入到数据库中。

Answer 1

你有这些列：

(deodoriser,carpet,carpetrepair,furniture,tabs,urine)

你正在插入这个：

'$idextra[$i]'

这是 6 列和 1 个值。正如错误所说，那不一样。

你的意思可能是这样的：

('{$idextra[1]}','{$idextra[2]}','{$idextra[3]}','{$idextra[4]}','{$idextra[5]}','{$idextra[6]}')

如果你想预先从你的数组中创建一个字符串，使用类似这样的东西 implode

$yourString = implode("','",$idextra);
$qu="INSERT INTO bs_reservations (deodoriser,carpet,carpetrepair,furniture,tabs,urine)
      VALUES ('{$yourString}')";

echo 查询以确保它是理智的:)

Answer 2

不要为您的复选框使用数组，而是为它们指定不同的名称，例如

<input type="checkbox" name="carpetrepair" id="carpetrepair" value="Carpet Repair Tools"/>

然后检查是否有任何被检查：

$options = explode(",","deodoriser,carpet,carpetrepair,furniture,tabs,urine");
$sql = "INSERT INTO bs_reservations SET ";
foreach($options as $opt){
  if (isset($_POST[$opt])) {
    $sql.= "`$opt`=1,";
  }
}
$sql = rtrim($sql,",");
