如何让我的复选框循环单独更新每个复选框，而不是在php和mySQL中同时更新它们？
我可以更新复选框，但它们不能完全正常工作。当两个框都为空时，我可以选中其中一个，并且两个框都会更新为选中。如果两个框都选中，我必须取消选中这两个框，以便将它们更新为未选中。我不能让一个框被选中，另一个框被取消选中 有什么想法吗 我真的很感谢你的帮助 mySQL表格如何让我的复选框循环单独更新每个复选框，而不是在php和mySQL中同时更新它们？,php,mysql,checkbox,mysqli,Php,Mysql,Checkbox,Mysqli,我可以更新复选框，但它们不能完全正常工作。当两个框都为空时，我可以选中其中一个，并且两个框都会更新为选中。如果两个框都选中，我必须取消选中这两个框，以便将它们更新为未选中。我不能让一个框被选中，另一个框被取消选中 有什么想法吗 我真的很感谢你的帮助 mySQL表格 id | departments_fk | qsps_fk | visible 270 | 1 | 218 | 1 271 | 22 | 218 |

您需要循环查看“部门复选框”。现在您并没有得到它们的值，只是检查是否设置了整个POST变量
if(!empty($_POST['department-checkBoxes'])) {
foreach($_POST['department-checkBoxes'] as $check) {
echo $check;
//only checked checkboxes come to $POST
$query2 = "UPDATE junction_departments_qsps SET ";
$query2 .= "checked = 1 ";
$query2 .= "WHERE departments_fk = {$checked} ";
$query2 .= "AND qsps_fk = {$id_qsp} ";
$result2 = mysqli_query($db_connection, $query2);
}
谢谢你的快速回答，但我不确定该在哪里使用此代码。是否在我的流程代码或表单中使用它？如果在流程代码中使用，是否需要运行第二个查询？在我完成第一个foreach循环和查询之后，我会使用它吗。$U POST中将只显示选中的复选框。感谢您的澄清，但我仍然无法使其正常工作。请粘贴您的最新代码并指定问题所在。我在上面添加了我的代码。数据库似乎根本没有更新。在我的原始代码中，它至少更新了两个复选框。非常感谢。
