How to E-mail Form Data

Hi there. New here.

I have this free form:
http://members.optuszoo.com.au/~renmarkholiday/form/form.html
But I can't figure how to get it to e-mail input information to my e-mail account.
I see <form id="form_667084" class="appnitro" method="post"
action=""> Which I have learnt "" means the information is submitted to the page to process?

If I change this to method="GET" action="mailto:myemail" it doesn't seem to help.

Any ideas. Also when the page refreshes, can I get it to display "Complete!"
or an image or something nice?

Thanks a heap! Trying to fancy up an old site.

 

guessing I am missing the .php side of it, the more I look into it.
if this javascript file helping?

EDITED:

Ok I have tried to make a .php it is freaking horrible I know.
I don't know what i'm doing. Any help appreciated.

if you want to send your form data as email. then you can use php mail function to send email.

<?php
if(isset($_POST['user_name']) && isset($_POST['email']))
{
 
    $user_name = $_POST['user_name'];
    $email = $_POST['email'];
 
    if(!empty($user_name) && !empty($email))
    {
        mail($email, "This is the email subject", "Your message");
    }
}
else
{
 
echo '<form action="" method="post">';
echo 'user name:<input type="text" name="user_name">';
echo 'E-mail To: <input type="email" name="email">';
echo '<input type="submit" value="Send E-mail">';
echo '</form>';
}
?>

PHP:

This is how you can send email ​

 

That will work for this particular form?

Look, I don't have time to view full code. Just tell me what type of error you are getting.

and one more thing, send_form_email.php is readable by any outside user, and that is not good for you, if you are storing data in database. so, change the file to 644 permission.

if you want then i can create a form as you required just PM me.
