两个名称为engine1和engine2的集合。我想使用此代码使用implode将它们插入到我的数据库中。

$_POST['engine1'] = array();
    $_POST['engine2'] = array();

    $engine1 = implode(',', $_POST['engine1']);
    $engine2 = implode(',', $_POST['engine2']);

但每次检查我的数据库表时，列都是空的。你认为我做错了什么？请帮忙！

Answer 1

您将$ _POST ['engine1']声明为空数组，如果存在则覆盖它。删除以下行：

$_POST['engine1'] = array();
$_POST['engine2'] = array();

这样$ _POST ['engine1']来自POSTED表单值。

Answer 2

删除以下行：

$_POST['engine1'] = array();
$_POST['engine2'] = array();

仅使用：

$engine1 = implode(',', $_POST['engine1']);
$engine2 = implode(',', $_POST['engine2']);

使用implode函数在表的一列中插入多个复选框
