【问题描述】：
您好，我有多个复选框，名称为 make 和 female但它也会出错
Undefined index: Female in /storage/sdcard1/www/3/signup/index.php on line 11
但我不希望出现此错误，并且我希望 if 女性不选择它插入 false 并且不显示错误我不希望选中的复选框值为 true，因为它是在数据库中写入的
代码索引.php
<?php
if(isset($_POST['submit'])){
$conn = new PDO("sqlite: sign.db");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$Email = $_POST['Email'];
$First = $_POST['First'];
$Last = $_POST['Last'];
$Password = $_POST['Password'];
$Male = $_POST['Male'];
$Female =$_POST['Female'];
$Dateofb = $_POST['Dateofb'];
require_once 'imp.php';
}
?>

【问题讨论】：
-
只提交选中的复选框。您需要检查是否在
$_POST中设置了框的名称并手动分配您希望使用的值。 -
好的，我会尝试分配一个值，但是如果我不选择女性怎么办，女性上设置的值仍然会得到输入
-
未选中的框根本不会出现在
$_POST中。因此，您需要使用isset选中所有复选框。如果它们没有设置，那么你可以给你的变量一些你想要的默认值（你提到了false）。
