使用 PDO 插入多行

I have a multicheckbox in a <form> tag like this:

<input type="checkbox" name="del[]" value="<?php echo $menuItems['id']; ?>">

我使用此代码询问此表单:

I ask this form with this code:

if (isset($_POST['subgruppe'])) {
        $ids = array();

    foreach ($_POST['del'] as $pval) {
        $ids[] = (int) $pval;
    }

    $ids = implode(',', $ids);
    echo "groupids";
    echo $ids;
    echo "userid:";
    echo $_POST['userid'];

这向我展示了这样的结果:

This shows me a result like this:

groupids13,9...userid:5 

我需要一个给我这样结​​果的语句:

I need a statment that give me a result like this:

INSERT INTO user_groups (usergroup, userid) VALUE (13,5),(9,5)

...你能给我一个提示我如何检查这个吗?我想我可以解决一个给我的解决方案:(13,5),(9,5)... 变成一个变量.

... Can you give me a hint how i can check this? I think I can handel a solution that give me: (13,5),(9,5)... into a variable.

非常感谢:)

推荐答案

您不必为所有 INSERTS 构建单个字符串，只需在循环时插入即可.

You don't have to build a single string for all of your INSERTS simply insert while you are looping.

例如:

$sql = "INSERT INTO user_groups (usergroup, userid) VALUE (:usergroup, :userid)";
$stmt = $pdo->prepare($sql);
foreach ($_POST['del'] as $pval) {
    $stmt->execute(array(':usergroup'=>(int) $pval, 
                         ':userid'=>$_POST['userid']
    ));
}
