这是我的代码，因为你可以看到传递给变量的输入是我想要的。请帮助我现在只是填补空白，因为我需要问这个问题，我目前正在重新安装xammp，希望它能解决问题，但如果这是代码问题，任何帮助都将不胜感激。
<?php
$Name = isset($_POST['name']);
$Car = isset($_POST['car']);
$Night = isset($_POST['yes']);
$Siteid = isset($_POST['siteid']);
$Date = isset($_POST['datepicker']);

isset()返回布尔值，并且您正在将isset()函数的值分配给参数，因此当您尝试回显布尔值时，您会看到"1"。试试这个代码：
$Name = isset($_POST['name']) ? trim($_POST['name']) :'';
isset()返回布尔值（true或false），可以表示为1或0。
这就是为什么你总是看到1。
您需要正确设置变量：
//wrong
$Name = isset($_POST['name']);
//correct
$Name = isset($_POST['name'])?$_POST['name']:'';
