PHP Web窗体上的多个错误

Matthew 发表于 Dev

马修

我正在设计的PHP表单有问题。我正在使用以下基本代码来验证我的网络表单并快速执行任务：

http://www.html-form-guide.com/php-form/php-form-validation.html

到目前为止，所有内容都按照我想要的方式设置，除了错误消息。请让我解释一下这种不可接受的行为，希望这里有人可以帮助我进行纠正。

所以...我的表单上有4个必填字段（名字，姓氏，电子邮件和下拉列表）。当我测试表单并仅输入例如“我的名字”时，即使我确实填写了“名字”字段，表单也会返回每条错误消息，包括旨在用于“名字”的错误消息。

无论是什么组合，无论我填写了多少字段，只要它不是完整的表单（在这种情况下，它都会毫无问题地提交），则同样适用。无论返回多少条错误消息，还是总的组合，总会返回4条错误消息。有人可以帮忙吗？这是代码：

也许如果您在命名约定上更加谨慎：

$disp_Nearest_City = isset($_POST["Nearest City"])?$_POST["Nearest City"]:"";
                                   ^^^^^^^^^^^^---spot the difference
<select name="Nearest_City" value="<?php echo htmlentities($disp_name) ?>" >
              ^^^^^^^^^^^^---spot the difference
