如何让我的复选框循环单独更新每个复选框，而不是 php 和 mySQL 中的两个复选框？

Question

我可以让复选框更新，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状态。如果两个框都被选中，我必须取消选中两个框才能将它们更新为未选中。我无法让一个框被选中而另一个框被取消选中。

有什么想法吗？

非常感谢您的帮助。

Answer 1

您需要遍历 'department-checkBoxes'。现在您没有获得它们的值，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); 

}
