PHP Success message after submit - php

Question

I'm using a simple php code to send mail from my website
<?php
$headers ="From:<$from>\n";
$headers.="MIME-Version: 1.0\n";
$headers.="Content-type: text/html; charset=iso 8859-1";
mail($to,$subject,$body,$headers,"-f$from");
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$formcontent="From: $name \n Message: $message";
$recipient = "contato#pedrogps.com";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thanks for your message";
?>
when i submit the email, it brings to another page (mail.php) with the "thanks for your message" message.
What can i do to display this message inside my html page without switching pages.

Answer 1

There are two ways one is use AJAX and another one:
make form action empty like
<form name="form1" action="" method="post">
before form start or top of the page write this php code:
if(isset($_POST)){
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$formcontent="From: $name \n Message: $message";
$recipient = "contato#pedrogps.com";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thanks for your message"; // store this msg in a variable and display wherever you required to echo
}

If you do not want the webpage to load, when submitting, you'll need some JavaScript.
<form id="mailForm">
<input type="text" name="name">
<input type="text" name="email">
<input type="text" name="message">
<input type="submit" value="Send">
</form>
<div id="result"></div>
<script>
$('#mailForm').submit(function(e) {
e.preventDefault();
var formData = $('#mailForm').serialize();
var url = "mail.php";
var posting = $.post(url, formData);
posting.done(function(data) {
$("#result").append(data);
});
});
</script>
Remember to load the jQuery library, read more about jQuery here: https://learn.jquery.com/about-jquery/how-jquery-works/. Read more about the jQuery.post() here: https://api.jquery.com/jquery.post/
If you do not care if the webpage loads, when submitting, then you can easily use the include function in PHP.
<form id="mailForm" method="POST">
<input type="text" name="name">
<input type="text" name="email">
<input type="text" name="message">
<input type="submit" name="mail" value="Send">
</form>
<div id="result">
<?php
if(isset($_POST['mail']))
{
include("mail.php");
}
?>
</div>
Maybe you should check some more things than only the $_POST['mail'] is set, but you'll get the idea.
