在 sql 中插入复选框并使用 php 回显它们

Question

我正在构建一个表单来输入不同的数据来表征事件（名称、日期、事件类型）到 sql db 中，以便以后可以按位置搜索它们。

下面是html表单，将数据放入db的php文件（insert.php），最后是搜索结果的php。 问题出在复选框上，我试图让多个值存储在同一个 sql 列中，有点像可以在搜索中使用的标签。

我现在的问题是，当我处理表单时，复选框列中的 sql 表中的条目显示为“数组”，然后它不会显示在搜索结果中。 不知道是表中数据输入错误还是结果显示的问题。

非常感谢任何帮助。

将 $_POST['eventtype'] 转换为字符串：

if( isset( $_POST['eventtype'] ) && is_array( $_POST['eventtype'] )) {
    $eventtypes = join( ',', $_POST['eventtype'] );
} else {
    $eventtypes = '';
}

在您的 INSERT 中使用 $eventtypes。
