Question

我正在联系我们表格而不刷新页面。但是在我点击发送按钮后，即使字段为空，我的必需属性也不起作用。请帮帮我

contact.html

<!DOCTYPE html>
<html>
<head>

<link rel="stylesheet" media="screen" href="styles.css" >
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){

$('#submit').click(function(){

$.post("send.php", $("#mycontactform").serialize(),  function(response) {   
 $('#success').html(response);
 //$('#success').hide('slow');
});
return false;


});

});
</script>
</head>
<body>

<form id="mycontactform" class="contact_form" action="" method="post" name="contact_form">
    <ul>
        <li>
             <h2>Contact Us</h2>
             <span class="required_notification">* Denotes Required Field</span>
        </li>
        <li>
            <label for="name">Name:</label>
            <input type="text"  id="name"  name="name" placeholder="John Doe" required />
        </li>
        <li>
            <label for="email">Email:</label>
            <input type="email" name="email" id="email"  placeholder="john_doe@example.com" required />
            <span class="form_hint">Proper format "name@something.com"</span>
        </li>

        <li>
            <label for="message">Message:</label>
            <textarea name="message" id="message"  cols="40" rows="6" required ></textarea>
        </li>
<li>
            <input type="button"  class="submit" style="width:70px; text-align:center; height:30px; margin-left:200px; cursor:pointer"  value="SEND" id="submit" />


        </li><div id="success" style="color:red;"></div>
</form>
</body>

send.php

<?php

// Here we get all the information from the fields sent over by the form.
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

    $to = 'babloopuneeth@gmail.com';
    $subject = 'the subject';
    $message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message;
    $headers = 'From: youremail@domain.com' . "\r\n";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { // this line checks that we have a valid email address
    mail($to, $subject, $message, $headers); //This method sends the mail.
    echo "Your email was sent!"; // success message
}else{
    echo "Invalid Email, please provide an correct email.";
}
?>

以上是我的代码。请帮我。我希望在单击按钮时可以使用必需的属性。

这只是我的意见，但我会使用PHP来检查输入字段是否为空。

只要有一个if语句来查看它们是否已填写就可以了。

<?php

// Here we get all the information from the fields sent over by the form.
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];

if($name=='' || $email=='' || $message=='') { //Make sure all of the fields are not empty
echo "Please fill in all of the fields";
}
else { //If they are filled in, process the rest of the form

$to = 'babloopuneeth@gmail.com';
$subject = 'the subject';
$message = 'FROM: '.$name.' Email: '.$email.'Message: '.$message;
$headers = 'From: youremail@domain.com' . "\r\n";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) { // this line checks that we have a valid email address
    mail($to, $subject, $message, $headers); //This method sends the mail.
    echo "Your email was sent!"; // success message
}else{
    echo "Invalid Email, please provide an correct email.";
}
}
?>

必需属性不起作用
