Php 使用复选框值更新SQL数据库
好的，我知道这个问题已经被回答了好几次，但我就是不能让我的工作 我的数据库中有8周的时间（设置为列），我用php显示这些时间的值，如下所示Php 使用复选框值更新SQL数据库,php,mysql,Php,Mysql,好的，我知道这个问题已经被回答了好几次，但我就是不能让我的工作 我的数据库中有8周的时间（设置为列），我用php显示这些时间的值，如下所示 <form method="post" id="updating" action="<?php $_PHP_SELF ?>"> <?php $count = 1; foreach ($results as $v) { while($count<9){

<?php

<input name="update" type="submit" id="update" value="Update">

我的逻辑是，它打印出1,0,0,1,0,0,0（勾选框1和4）或任何勾选框。但是它只是打印出1,1，所以我无法知道它们是什么索引，以及接下来我应该在哪一周进行更新我添加了一些非常粗糙的更新方法。在使用

我回到这个答案是为了参考一些东西，我刚刚意识到我正在为复选框重新使用
