php - 输入表单将数据作为数值而不是实际数据插入

Question

您好，我有一个输入表单，我已将虚拟数据添加到此表单中，出于某种原因，它将数据添加为数值，即“1”。我不确定我哪里出错了，这与我在上传此数据之前选择电子邮件的 COUNT 有什么关系吗？

提前致谢

我的代码如下:

Answer 1

你犯了一个小错误。你写过:

$username = isset($_POST['username']);

但我认为您真正想做的是:

$username = isset($_POST['username']) ? $_POST['username'] : null;

事实上，您不是在存储用户名等本身，而是在发送这些值时。然后将 bool 值 true 转换为数字 1。

要使其正常工作，您还必须为 $name 和 $email 更改它，因为您还在那里使用了 isset。
