Php 删除数据库中的记录
我做了一个程序，将删除数据库中的记录，它正在工作，但该程序会自动删除记录，而无需确认。我想让我的程序在删除之前先确认，我该怎么做 内容功能代码：Php 删除数据库中的记录,php,Php,我做了一个程序，将删除数据库中的记录，它正在工作，但该程序会自动删除记录，而无需确认。我想让我的程序在删除之前先确认，我该怎么做 内容功能代码： //********************************************************************* function Content() { if(isset($_POST['btnAdd'])) //if in case 'Add Entry' button is click {

$code=off-topic：请注意，mysql_xxx（）
函数已经过时。建议使用PHP更现代的数据库API之一，例如PDO库。此页面如何调用？另外，请注意，您的代码容易受到SQL注入攻击，因为您没有转义输入变量（即$uname
）。请发布删除表单。为什么不使用客户端代码（Javascript）进行确认？
