Php 邮件表单发送成功消息并检查是否输入！空的
所以我正在制作一个联系表单，当我们点击提交时，它会向管理员发送一封电子邮件，包括输入内容。电子邮件功能已经在运行，我缺少的是检查输入字段是否为空的验证。我尝试在输入标记中添加必需的属性。它可以在本地主机上工作，但由于某些原因不能在服务器上工作。此外，它还需要弹出一条消息，确认您已提交表单。我在这里使用了onclick函数。但我无法澄清它是否有效，因为它只需要在提交成功且没有空字段时弹出消息 这是我使用的代码。已建立连接Php 邮件表单发送成功消息并检查是否输入！空的,php,forms,email,Php,Forms,Email,所以我正在制作一个联系表单，当我们点击提交时，它会向管理员发送一封电子邮件，包括输入内容。电子邮件功能已经在运行，我缺少的是检查输入字段是否为空的验证。我尝试在输入标记中添加必需的属性。它可以在本地主机上工作，但由于某些原因不能在服务器上工作。此外，它还需要弹出一条消息，确认您已提交表单。我在这里使用了onclick函数。但我无法澄清它是否有效，因为它只需要在提交成功且没有空字段时弹出消息 这是我使用的代码。已建立连接 <!---Mail Starts--> <?php if

有不同的方法吗？这里有一个验证器，我用它作为内部开发工具的一部分。它是一个服务器端，是一个更大框架的一部分，但对您来说还可以

用于验证输入。例如电子邮件当然有很多方法可以做到这一点，但这需要你自己编写一些代码。对于验证，您不能隐式信任客户端验证。您可能希望包含服务器端代码以检查是否提交了值。例如，您当前检查isset$\u POST['submit']，查看表单是否已发布。您可以执行类似的检查，以查看表单中是否发布了特定数据元素，您可以检查发布字符串的长度等。构建逻辑以执行检查并相应地发送或不发送消息。
$validator = new InputValidation();
$val = $validator->validateInputs($data);
if (isset($val['error']) && $val['error'] == true) {
// do whatever
);
}
