how do i make my contact form work? - php

Question

The code below acts strange when I click the button on my website.
First it opens a new page where the form is again displayed but without any css or js. Then when I refill all the info and click send, it says its submitted but it wont actually sent the email.
I have tried to modify the code I am still new to php.
Code below displays and functions the contact form.
<?php
$action=$_REQUEST['action'];
if ($action=="")
{
?>
<form action="" method="POST" enctype="multipart/form-data">
<input type="hidden" name="action" value="submit">
Your name:<br>
<input name="name" type="text" value="" size="30"/><br>
Your email:<br>
<input name="email" type="text" value="" size="30"/><br>
Your message:<br>
<textarea name="message" rows="7" cols="30"></textarea><br>
<input type="submit" value="Send email"/>
</form>
<?php
}
else /* send the submitted data */
{
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$message=$_REQUEST['message'];
if (($name=="")||($email=="")||($message==""))
{
echo "All fields are required, please fill the form again.";
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Personal Plate inquiry from website";
mail("mymail#hotmail.com", $subject, $message, $from);
echo "Email sent!";
}
}
?>

Answer 1

There are some mistakes on your code: use $_POST instead of $_REQUEST. You can try this way:
<?php
if(isset($_POST['submit'])){
$name=$_POST['name'];
$email=$_POST['email'];
$message=$_POST['message'];
if (($name =="")||($email=="")||($message==""))
{
echo "All fields are required, please fill the form again.";
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Personal Plate inquiry from website";
mail("mymail#hotmail.com", $subject, $message, $from);
echo "Email sent!";
}
}
?>
<form action="" method="POST" enctype="multipart/form-data">
<input type="hidden" name="action" value="submit">
Your name:<br>
<input name="name" type="text" value="" size="30"/><br>
Your email:<br>
<input name="email" type="text" value="" size="30"/><br>
Your message:<br>
<textarea name="message" rows="7" cols="30"></textarea><br>
<input type="submit" name="submit" value="Send email"/>
</form>
