我的形式有些困难没有按预期工作。有效地，当我点击提交按钮时，它会发送电子邮件，即使我（思考）已设置验证以阻止它发送，直到完成所有相关字段。

任何人都可以协助验证出错的地方吗？
非常感谢，

您正在进行浏览器端验证，为此目的，javascript是最好的。 http://www.w3schools.com/js/js_validation.asp这是您可以找到验证的链接。
并且正如您所提到的那样，您正在使用HYML5，因此只需在标记中添加“ required ”，这意味着此字段是必填字段。还有其他预定义验证可用在HTML5中
答案 1 :(得分：0)
您的脚本清除所有变量，然后检查$ _POST变量。但是，当检查通过时，您没有设置新值 - 除非上面没有显示test_input函数：
$mdDateLocaleProvider.formatDate = function(date) {
return moment(date).format('DD/MM/YYYY');
};
$mdDateLocaleProvider.parseDate = function(dateString) {
var m = moment(dateString, 'DD/MM/YYYY', true);
return m.isValid() ? m.toDate() : new Date(NaN);
};
因此，您可以在页面顶部设置
$telephone = test_input($_POST["telephone"]);
然后检查是否
$telephone = '';
有效，如果是，则将$ telephone设置为无法解析的值。然后在您的电子邮件中，您尝试发送$ telephone，但该值仍为空。

问题是，即使您正在验证表单输入，也不会在构造邮件之前检查是否存在任何错误，即$firstNameErr，$lastNameErr等是否为空
if(empty($firstNameErr) && empty($lastNameErr) && empty($emailErr) && empty($telephoneErr) && empty($messageErr)){
// construct the mail and send it
}else{
// display error messages
}
所以你现有的代码应该是这样的：
<?php
$page_title = "EcoPiggy: PHP Contact Us- Testing";
// define variables and set to empty values

$firstNameErr = $lastNameErr = $emailErr = $telephoneErr = $messageErr = "";
if (isset($_POST['signup'])) {
if (!empty($_POST['tracey'])) {
die;
}
$marketingConsent = ($_POST["marketingConsent"]);
$copyEmail = ($_POST["copyEmail"]);
if(empty($_POST["firstName"])) {
$firstNameErr = "* First Name is required";
} else {
$firstName = test_input($_POST["firstName"]);
if (!preg_match("/^[a-zA-Z0-9 ]*$/",$firstName)) {
$firstNameErr = "* Only letters and white space allowed";
}
$min=3;
if(strlen($firstName) < $min) {
$firstNameErr = "Validation failed: Too Small minimum 3 characters";
}
$max=45;
if(strlen($firstName) > $max) {
$firstNameErr = "Validation failed: Too Large maximum 45 characters";
}
}
if(empty($_POST["lastName"])) {
$lastNameErr = "* Last Name is required";
