创建PHP iframe表单以将数据发布到电子邮件地址以及数据库表

The first thing I'm struggling to figure out is if it's possible to add this PHP form to an iframe so I can drop it on several different sites (Facebook, Wordpress, personal sites etc). If not how else can I create a form that will allow me to drop the iframe code on different sites and still function correctly?

Currently my form just submits the data to my email but I want the data to also get posted and stored within a database. Can I do this within an iframe?

Below is my form..

HTML

<form action="mail.php" method="POST">
<p>Name</p> <input type="text" name="name">
<p>Email</p> <input type="text" name="email">
<p>Phone</p> <input type="text" name="phone">

<p>Request Phone Call:</p>
Yes:<input type="checkbox" value="Yes" name="call"><br />
No:<input type="checkbox" value="No" name="call"><br />

<p>Website</p> <input type="text" name="website">

<p>Priority</p>
<select name="priority" size="1">
<option value="Low">Low</option>
<option value="Normal">Normal</option>
<option value="High">High</option>
<option value="Emergency">Emergency</option>
</select>
<br />

<p>Type</p>
<select name="type" size="1">
<option value="update">Website Update</option>
<option value="change">Information Change</option>
<option value="addition">Information Addition</option>
<option value="new">New Products</option>
</select>
<br />

<p>Message</p><textarea name="message" rows="6" cols="25"></textarea><br />
<input type="submit" value="Send"><input type="reset" value="Clear">
</form>

PHP

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$call = $_POST['call'];
$website = $_POST['website'];
$priority = $_POST['priority'];
$type = $_POST['type'];
$message = $_POST['message'];
$formcontent=" From: $name 
 Phone: $phone 
 Call Back: $call 
 Website: $website 
 Priority: $priority 
 Type: $type 
 Message: $message";
$recipient = "youremail@here.com";
$subject = "Contact Form";
$mailheader = "From: $email 
";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thank You!";
?>

Yes, you can do this.

If you host the iframe on your host, you have direct access to your database. The mail.php file should do the posting.

Use this inside your code, before or after mailing the message:

define('DBHOST', 'localhost');
define('DBNAME', '');
define('DBUSER', '');
define('DBPASS', '');

function nuukDb() {
    $nuukDb = new PDO('mysql:host=' . DBHOST . ';dbname=' . DBNAME . ';charset=utf8', DBUSER, DBPASS);
    $nuukDb->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $nuukDb->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
}

$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];

$nuuk = $nuukDb->prepare("INSERT INTO tablename (value1, value2, value3) VALUES ('$name', '$email', '$phone')");
$nuuk->execute();
