我有一个包含多个复选框的表单。在提交时，我希望能够获取复选框并能够将它们存储在sql中。我正在使用的foreach不工作，我尝试了很多其他方法，但没有一个工作。请帮忙谢谢！
我从帖子开头就更新了我的代码以解决问题，但仍然遇到问题。
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
include_once 'includes/db_connect.php';
include_once 'includes/functions.php';
session_start();
if(isset($_POST['Submitme'])){
if(!empty($_POST['flight'])){
print_r($_POST);
foreach($_POST['flight'] as $key=>$selected){
echo $selected."</br>";
}
}
}
?>

答案 0 :(得分：0)
您忘了为您提供价值checkboxes只是为所有复选框提供价值，然后重试。
<input type="checkbox" name="flight[]" id="2A" value='2A' />
将PHP部分更改为以下
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
include_once 'includes/db_connect.php';
include_once 'includes/functions.php';
session_start();
if(isset($_POST['SubmitFlight'])){
if(!empty($_POST['flight'])){
foreach($_POST['flight'] as $key=>$selected){
echo $selected."</br>";
}
}
}
?>
