我得到未定义的索引调用，指向$ call =“No”;线。然而，脚本根本不应该运行，因为我发布了一个空白表单？当我回显输入字段时它们是空白但是如果把IF语句放入检查它们是否被设置（isset）它进入语句就像它们已被设置一样？我应该使用除了isset之外的其他东西来检查空输入吗？这通常有效，所以我很困惑，为什么现在不呢？

Answer 1

在$ _POST ['call']中添加缺少的分号后，您的代码运行正常;

正确的一个应该是$ call =（$ _POST ['call']）;

提交空表单时会显示错误消息。所以我认为验证工作正常。

Answer 2

$_POST['call']

上缺少分号

if(!isset($_POST['call'])) {
 $call = "No"; // if checkbox was left unchecked. Default is No
}
else {
    $call = $_POST['call']; // Missing semicolon here
}

html和php联系表单麻烦
