PHP / JavaScript电子邮件表格和验证
[英]Php/javascript email form and validation
问题描述
因此，我具有用于验证名字字段的JavaScript代码，一旦解决了此问题，我将添加更多验证。
因此，基本上，如果未填写该字段，则返回false。 如果返回true，则继续到email.php发送电子邮件。 唯一的问题是它没有将电子邮件发送到设置的地址。 我对哪里出错了感到困惑。
当该字段为空且有输入时，JavaScript正常工作。 救命。
PS：出于隐私目的，我已删除了电子邮件地址。
contact.html上的JavaScript：
<script>
function validateForm() {
if (document.forms['email'].fname.value == ""){
alert("First name must be filled out");
return false;
}
else{
alert("Thank you! Your message was recieved!");
return true;
}
};
</script>
contact.html上的HTML表单
<form id="email" name="email" onsubmit="return validateForm(this)" action="email.php" method="post" >
<div id="form_fname">
<label for="fname"><img src="images/firstname.png" width="94" height="17" alt="first name" /></label>
<input type="text" name="fname" id="fname" />
</div>
<div id="form_lname">
<label for="lname"><img src="images/lastname.png" width="89" height="17" alt="last name" /></label>
<input type="text" name="lname" id="lname" />
</div>
<div id="form_email">
<label for="email"><img src="images/email.png" width="53" height="17" alt="email" /></label>
<input type="text" name="email" id="email" />
</div>
<div id="form_message">
<label for="Message"><img src="images/message.png" width="77" height="17" alt="message" /></label>
<textarea name="message" id="message" cols="45" rows="5"></textarea>
</div>
<div id="form_submit">
<input type="submit" name="submit" id="submit" value=""/>
</div>
</form>
电子邮件中的PHP
<?php
if(isset($_POST['email'])) {
// Email and subject.
$email_to = "emailaddress";
$email_subject = "Mint Makeup & Beauty Enquiry";
$fname = $_POST['fname']; // required
$lname = $_POST['lname']; // required
$message = $_POST['message']; // required
$email_from = $_POST['email']; // required
// create email content
$email_content = "From:"." ".$fname." ".$lname."\n"."Email:"." ".$email_from."\n"."Message:"." ".$message;
//mail
mail($email_to, $email_subject, $email_content);
}
//return to contact page after submit.
header("location:contact.html");
?>

尝试
document.forms["email"]["fname"].value
代替
document.forms['email'].fname.value
您也可以通过这种方式获取字段：
document.getElementById('fname').value

您的表单中id =“ email”与输入id =“ email”冲突
您可以使用HTML5属性进行表单验证（在受HTML5支持的浏览器中）

我只是向您展示了客户端验证的工作方式以及表单的正确发布方式。您应该始终使用服务器端验证。
