Create success message on php form submit - php

Question

I'm trying to make a php mail form display a success message upon a successful submit.
I'm new to php and I'm not sure how to make this work.
As it sits now, after submit, the site just reloads at the top of the page. I'd like it to refresh at the contact div and display a success message.
Contact div html:
<div class="contact-wrapper" >
<div class="contact">
<div class="contact-left" id="contact">
<?php
if (isset($_REQUEST['email'])) {
echo "Thank you for your message.";
}
$mail_form = include('php/mail_form.php'); ?>
</div> <!-- end div contact -->
Contact from PHP:
<?php
function spamcheck($field)
{
//filter_var() sanitizes the e-mail
//address using FILTER_SANITIZE_EMAIL
$field=filter_var($field, FILTER_SANITIZE_EMAIL);
//filter_var() validates the e-mail
//address using FILTER_VALIDATE_EMAIL
if(filter_var($field, FILTER_VALIDATE_EMAIL))
{
return TRUE;
}
else
{
return FALSE;
}
}
if (isset($_REQUEST['email']))
{//if "email" is filled out, proceed
//check if the email address is invalid
$mailcheck = spamcheck($_REQUEST['email']);
if ($mailcheck==FALSE)
{
echo "Invalid input";
}
else
{//send email
$email = $_REQUEST['email'] ;
$subject = $_REQUEST['subject'] ;
$message = $_REQUEST['message'] ;
mail("idc615#gmail.com", "Subject: $subject",
$message, "From: $email" );
header("location: index.php");
}
}
?>

Answer 1

Try this code... You need to halt your script for some time so that user can see success or failure message. Without sleep user will not be able to see message as header will execute immediately.
if(mail("idc615#gmail.com", "Subject: $subject",$message, "From: $email" )){
echo "Thank you for your message";
sleep(2); // sleep for 2 seconds. Enough to display success message
//header will execute after 2000ms(2s)
header("location: index.php");
}else{
echo "Unable to send message";
sleep(2); // sleep for 2 seconds
header("location: index.php");
}
or try code given below:
in Contact from PHP
if(mail("idc615#gmail.com", "Subject: $subject",$message, "From: $email" )){
header("location: index.php?status=1");
}else{
header("location: index.php?status=0");
}
in index.php
if(isset($_GET['status'])){
$status = $_GET['status'];
if($status == 1){
echo "Thank you for your message";
}else if($status == 0){
echo "Unable to send message";
}
}

Answer 2

$name = mysql_real_escape_string($_POST['name']);
$email = mysql_real_escape_string($_POST['email']);
$message = mysql_real_escape_string($_POST['message']);
if(isset($_POST['contactrgtr']))
{
$query = "insert into contact_us(name,email,message)values('$name','$email','$message')";
$res = mysql_query($query);
if($res){
$message = 'Your Message Successfully Sent';
include_once('contact.php'); } `
Then in contact.php page you have to define <?php $message ?>.
