Question

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间，因为我需要问问题，我目前正在重新安装xammp希望它解决问题，但如果它是一个代码问题，任何帮助最感激。

<?php
$Name = isset($_POST['name']);
$Car  = isset($_POST['car']);
$Night = isset($_POST['yes']);
$Siteid = isset($_POST['siteid']);
$Date = isset($_POST['datepicker']);


?>

Answer 1

isset()返回布尔值，并且您将isset()函数的值赋给参数，因此当您尝试回显布尔值时，您会看到＆＃34; 1＆＃34;。试试这段代码：

$Name = isset($_POST['name']) ? trim($_POST['name']) :'';

Answer 2

isset()返回一个布尔值（true或false），可以表示为1或0。

这就是为什么你一直看到1。

您需要正确设置变量：

//wrong
$Name = isset($_POST['name']);

//correct
$Name = isset($_POST['name'])?$_POST['name']:'';

每当我将变量回显或写入文本文件时，它都会输出＆＃34; 1＆＃34;要么是webapge，要么是文本文件。
