How do I prompt my alert to the user with a php file?

I want to make a contact form using php and javascript and I'm having a hard time with the alert() function. What I want to do, is inform the user of what's happening in the back end. I noticed that my "echo" functions get prompted into the console and I want to make them visible as an alert() function.
Here is my javascript:
$(document).ready(function() {
$("#submit").click(function() {
console.log("button clicked");
var name = $("#name").val();
var adresse = $("#adresse").val();
var telephone = $("#telephone").val();
var email = $("#email").val();
var project_place = $("#project_place").val();
var message = $("#message").val();
$("#returnmessage").empty(); // To empty previous error/success message.
// Checking for blank fields.
if (name == '' || email == '' || telephone == '' || message == '') {
alert("Please fill out the required fields.");
} else {
// Returns successful data submission message when the entered information is stored in database.
$.post("includes/mail.php", {
name1: name,
adresse1: adresse,
telephone1: telephone,
email1: email,
project_place1: project_place,
message1: message
}, function(data) {
console.log(data);
$("#returnmessage").append(data); // Append returned message to message paragraph.
if (data == "Email sent.") {
$("#frmContact")[0].reset(); // To reset form fields on success.
alert("Email sent.");
}
});
}
});
});
and here's my php:
<?php
// Fetching Values from URL.
$name = $_POST['name1'];
$adresse = $_POST['adresse1'];
$telephone = $_POST['telephone1'];
$email = $_POST['email1'];
$lieu_du_projet = $_POST['lieu_du_projet1'];
$message = $_POST['message1'];
$email = filter_var($email, FILTER_SANITIZE_EMAIL); // Sanitizing E-mail.
// After sanitization Validation is performed
if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
if (!preg_match("/^[0-9]{10}$/", $telephone)) {
echo "Please, enter a valid number";
} else {
$subject = $name;
// To send HTML mail, the Content-type header must be set.
$headers = 'MIME-Version: 1.0' . "rn";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "rn";
$headers .= 'From:' . $email. "rn"; // Sender's Email
$headers .= 'Cc:' . $email. "rn"; // Carbon copy to Sender
$template = 'Hi ' . $nom . ","
. "\n\nThank you form contacting us,"
. "\nName: " . $name
. "\nAdresse: " . $adresse
. "\nTelephone: " . $telephone
. "\nEmail: " . $email
. "\nProject Place: " . $project_place
. "\nMessage: " . $message
. "\nThis is a confirmation email. "
. "\nWe'll get back to you as soon as possible";
$sendmessage = $template ;
// Message lines should not exceed 70 characters (PHP rule), so wrap it.
$sendmessage = wordwrap($sendmessage, 70);
// Send mail by PHP Mail Function.
mail("my#email.com", $subject, $sendmessage, $headers);
echo "Email sent.";
}
} else {
echo "Email invalid.";
}
?>
Any help would be appreciated, thanks a lot!

Alert box not working in php

This is my contact-form-handler.php file. After clicking submit button, I want an alert in PHP. I am receiving Mail successfully and redirect to my main page but without an alert message. How can I use the alert box in PHP?
My form is working fine, but this time I stucked in this simple task.
<?php
if(isset($_POST['submit'])){
//$companyMail = 'enesh#gmail.com';
$to = "eneshpal#gmail.com"; // this is your Email address
$customerMail = $_POST['formEmail']; // this is the sender's Email address
$first_name = $_POST['formFirstName'];
$last_name = $_POST['formLastName'];
$phone = $_POST['formPhone'];
$text = $_POST['formText'];
/* foreach($_POST['project_type'] as $project_type_value){} */
$projectType = implode(', ',$_POST['project_type']);
$scopeProject = implode(', ',$_POST['scope_project']);
$project_type_Str = 'Project Type : '.$projectType;
$scope_project_Str = 'Scope of Project : '.$scopeProject;
$subject = "Form Submission";
$message = "Hi, \n\n";
$message .= "First Name: ".$first_name . "\nLast Name: " . $last_name . " \nEmail: " . $customerMail . " \nPhone : " . $phone . "\nDescription: " . $text . "\n";
$message .= $project_type_Str."\n";
$message .= $scope_project_Str;
//$message2 = "Here is a copy of your message " . $first_name . "\n\n" . $_POST['message'];
//$headers = "From:" . $companyMail;
//$headers2 = "From:" . $to;
if(mail($to,$subject,$message)){
//echo 'Mail Sent';
//$message = "Thanks, We Will Contact you Shortly";
//echo "<script type='text/javascript'>alert('$message');</script>";
echo "<script>alert('Thanks, We Will Contact you Shortly');</script>";
header('Location:get_estimation.php');
}else{
echo 'Mail Not Sent';
}
//mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
/*if( "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.")
else die; */
// You can also use header('Location: thank_you.php'); to redirect to another page.
}
?>

In your case it would be better to redirect the user
header('Location:get_estimation.php?success=true');
and pass a GET-parameter.
When the GET-Parameter is set it will display what you want on your get_estimation.php-page

There are many problems with your script, but to answer your key question... you are echo'ing out the javascript code for an alert(), which will in turn prevent your php header('Location:get_estimation.php'); from executing because there has already been output sent to the browser before header was called. See here for more info.
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include, or require, functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.
As per your comment above...
Yes Sir I want just just wish to render a success message after the form has been submitted?
To give you an example of how to achieve what you need for this...
<?php
if (!empty($_GET['success'])) {
echo 'Thanks, we will contact you shortly';
exit;
}
if (isset($_POST['submit'])) {
$to = "eneshpal#gmail.com";
$customerMail = $_POST['formEmail'];
$first_name = $_POST['formFirstName'];
$last_name = $_POST['formLastName'];
$phone = $_POST['formPhone'];
$text = $_POST['formText'];
$projectType = implode(', ', $_POST['project_type']);
$scopeProject = implode(', ', $_POST['scope_project']);
$project_type_Str = 'Project Type : ' . $projectType;
$scope_project_Str = 'Scope of Project : ' . $scopeProject;
$subject = "Form Submission";
$message = "Hi, \n\n";
$message .= "First Name: " . $first_name . "\nLast Name: " . $last_name . " \nEmail: " . $customerMail . " \nPhone : " . $phone . "\nDescription: " . $text . "\n";
$message .= $project_type_Str . "\n";
$message .= $scope_project_Str;
if (mail($to, $subject, $message)) {
header('Location: get_estimation.php?success=1');
exit;
} else {
echo 'Mail Not Sent';
exit;
}
}
To explain, you should not be using a browser-native javascript alert rendered from php to pop-up and notify the user of a form submission success, especially immediately after a redirect. It's just a bad user experience, it hijacks the browser window until they click ok on it and you cannot really style native alert windows etc.
Instead you should redirect with a success GET variable after the mail is sent successfully (back to the original page, presuming that is get_estimation.php in my example - but you can redirect elsewhere to another script). Then you can detect the presence of this variable in the script redirected to and show an appropriate message etc.

echo "Thank You,will contact you soon";
echo "<script>setTimeout(\"location.href = 'get_estimation.php';\",3000); </script>";

Joomla 3.x Contact Form - Automatic Email Edits

Please be aware I am not very familiar with JavaScript and I am doing this to help out a coworker.
I am trying to make an edit to the contact form automatic email replies. The change I am looking to make is when a person sends an email to someone on the website a reply is sent back to the person stating "This is a copy of the following message you sent to WEBSITE PERSON via WEBSITE NAME." The person receiving the email only gets the name of the person that sent it and the message.
I need to add the "This is a copy of the following message you sent to WEBSITE PERSON via WEBSITE NAME" message to the other email because one person is receiving all emails and sending them to the appropriate person. I know, this sounds unreasonable but it is what has been requested.
I found the code in contact.php but I am not entirely sure how to make the change.
This is where the code is getting the portion that I need:
// Check whether email copy function activated
if ($copy_email_activated == true && !empty($data['contact_email_copy']))
{
$copytext = JText::sprintf('COM_CONTACT_COPYTEXT_OF', $contact->name, $sitename);
$copytext .= "\r\n\r\n" . $body;
$copysubject = JText::sprintf('COM_CONTACT_COPYSUBJECT_OF', $subject);
$mail = JFactory::getMailer();
$mail->addRecipient($email);
$mail->addReplyTo($email, $name);
$mail->setSender(array($mailfrom, $fromname));
$mail->setSubject($copysubject);
$mail->setBody($copytext);
$sent = $mail->Send();
}
return $sent;
}
}
And I need the above to work with
// Prepare email body
$prefix = JText::sprintf('COM_CONTACT_ENQUIRY_TEXT', JUri::base());
$body = $prefix . "\n" . $name . ' <' . $email . '>' . "\r\n\r\n" . stripslashes($body);
// Load the custom fields
if (!empty($data['com_fields']) && $fields = FieldsHelper::getFields('com_contact.mail', $contact->email_to, true, $data['com_fields']))
{
$output = FieldsHelper::render(
'com_contact.mail',
'fields.render',
array(
'context' => 'com_contact.mail',
'item' => $contact,
'fields' => $fields,
)
);
if ($output)
{
$body .= "\r\n\r\n" . $output;
}
}
$mail = JFactory::getMailer();
$mail->addRecipient($contact->email_to);
$mail->addReplyTo($email, $name);
$mail->setSender(array($mailfrom, $fromname));
$mail->setSubject($sitename . ': ' . $subject);
$mail->setBody($body);
$sent = $mail->Send();
I thought it would be as simple as copying some code around but I am was very wrong. I knwo there are overrides in Joomla to prevent core code from being touched. As soon as I can get this figured out I can do the override to properly add my changes.
Thank you in advance!

Sorry, i used mobile so it hard to check
// Check whether email copy function activated if ($copy_email_activated == true && !empty($data['contact_email_copy'])) { $copytext = JText::sprintf('COM_CONTACT_COPYTEXT_OF', $contact->name, $sitename); $copytext .= "\r\n\r\n" . $body; $copysubject = JText::sprintf('COM_CONTACT_COPYSUBJECT_OF', $subject);
// Load the custom fields if (!empty($data['com_fields']) && $fields = FieldsHelper::getFields('com_contact.mail', $contact->email_to, true, $data['com_fields'])) { $output = FieldsHelper::render( 'com_contact.mail', 'fields.render', array( 'context' => 'com_contact.mail', 'item' => $contact, 'fields' => $fields, ) ); if ($output) { $copytext .= "\r\n\r\n" . $output; } }
$mail = JFactory::getMailer(); $mail->addRecipient($email); $mail->addReplyTo($email, $name); $mail->setSender(array($mailfrom, $fromname)); $mail->setSubject($copysubject); $mail->setBody($copytext); $sent = $mail->Send(); } return $sent; } }

why does php fom submission keeps submitting every time I refresh?

So I submit my form and and every time I click ctrl-r it refreshes the page without alerting me it will resubmit the form. Every time I click the reload button on browser it asks me that it will reload but I already submitted the form so now I am getting a new submit every time and creating a new item in my sqlDB. I refresh and I do not know what I have to do to automatically refresh the page to where it wont save the form resubmit and is like a new page again.

I have tried adding a header(Location: index.php) But i get a weird error saying
Cannot modify header information - headers already sent by (output started at /Users/mine/Documents/www/website/schools/inc/header.php:67) in /Users/mine/Documents/www/website/schools/inc/footer.php on line 127

Unset $_POST variable after proccessing data in your footer.php
your header already send problem : It means some text was already outputted. Place your header() on top of your script. Or look at the ob_start and ob_end_clean() functions.

You can not use header() once text has been output to the browser. As your header file include presumably outputs HTML, header() cannot be used.
You can solve this in flowing ways:
Move the if statement above the header file include.
ob_start() at the top of the script to buffer the output.

"Submit" button sends mail but doesn't redirect?

This script is driving me up the wall. It's a simple submission form. I click the "submit" button and the email with all the submitted information is generated perfectly fine.
But I can't get the button to then redirect me to the "Thank You" page.
I've tried PHP, I've tried Javascript, I've even tried good old fashioned Meta Redirect. Nothing works.
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($email_to, $email_subject, $email_message, $headers);
header("location:http://amvleague.vitaminh.info/thankyou.html")
}
die();
?>
I've tried putting the "header" part at the top of the document. I've tried changing it to:
echo '<script>document.location="page2.html"; </script>';
I've generated so many emails with this script that gmail is now sending them all to spam. And I can't get the damn thing to redirect.
If anyone can help before I claw my eyes out, it would be much obliged. ^_^;;
EDIT: I've tried everything you've all suggested. It's as if the script just flat-out refuses to execute anything that comes after the mail command. Could there be a reason for this?
EDIT 2: Still nothing's working.
Here's the entire script (with Rolen Koh's modifications). Is there something hidden in here that is preventing the script from accessing anything that comes after the mail tag?

You can use the header() function to send a new HTTP header, but this must be sent to the browser before any HTML or text (so before the <!DOCTYPE ...> declaration, for example).
try this,this is what I am using
function redirect($url){
if (headers_sent()){
die('<script type="text/javascript">window.location.href="' . $url . '";</script>');
}else{
header('Location: ' . $url);
die();
}
}

Try this:
$mail = mail($email_to, $email_subject, $email_message, $headers);
if($mail)
{
header("location:http://amvleague.vitaminh.info/thankyou.html");
}
Also semi-colon is missing in your header("location:http://amvleague.vitaminh.info/thankyou.html") line but i guess it is typo error.

use location.href
echo '<script>window.location.href="page2.html"; </script>';
The window.location object can be written without the window prefix.

The line
header("location:http://amvleague.vitaminh.info/thankyou.html")
Needs to be
header("Location: http://amvleague.vitaminh.info/thankyou.html");
Note the capital "L", the space after the colon, and the semicolon at the end.
If this does not resolve your issue, then you have an issue in some other piece of code. To find it, you might try looking at the php error log. If you have access to the server, you can find this by using any of the following resources for your particular server.
http://www.cyberciti.biz/faq/error_log-defines-file-where-script-errors-logged/
Where does PHP store the error log? (php5, apache, fastcgi, cpanel)
Where can I find error log files?
If you are on a shared host, they might have some non-standard location for this file, in which case, it might be easiest to contact them and ask where their standard location of the php error log is.
