php .session_start show errors on contact.php from submit.php - javascript

I need the errors on a form to show up from the submit.php onto the form page at contact.php
I have tried with Session_Start, but it is not working. This is what I have so far.
Contact.php
<?php
ob_start();
session_start();
if ($_SESSION["error"] != "") {
echo $_SESSION["error"];
$_SESSION["error"] = "";
}
?>
<?php echo $error; ?>
Submit.php
<?php
ob_start();
session_start();
?>
<?php
//fields
$link_address = 'contact'; // page to redirect to
$honeypot = '';
$error = '';
$name = 'Name';
$email = 'Email';
$comments = 'Message';
if(isset($_POST['contactus'])) {
$honeypot = $_POST['email_confirm'];
$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments'];
// honeypot
if($honeypot)
exit(1);
<?php
//error messages
if(trim($name) == 'Name') {
$error = '<div class="error_message">Need your Name</div>';
} else if(trim($name) == '') {
$error = '<div class="error_message">Need your Name</div>';
} else if(trim($email) == 'Email') {
$error = '<div class="error_message">Need your Email</div>';
} else if(trim($email) == '') {
$error = '<div class="error_message">Need your Email</div>';
} else if(!isEmail($email)) {
$error = '<div class="error_message">Need a valid email</div>';
} else if(trim($comments) == 'Message') {
$error = '<div class="error_message">A Message is required</div>';
} else if(trim($comments) == '') {
$error = '<div class="error_message">A Message is required</div>';
}
if($error == '') {
if(get_magic_quotes_gpc()) {
$comments = stripslashes($comments);
}
//email address
$address = "mail#example.com";
//email message
$e_subject = 'Web Message from: ' . $name . '.';
$e_body = "From: $name\nEmail: $email \r\n\nMessage:\n$comments\n\n\n";
$msg = $e_body . $e_content . $e_reply;
if(mail($address, $e_subject, $msg, "From: $email\r\nReply-To: $email\r\nReturn-Path: $email\r\n"))
{
//success html page response
echo "<div id='succsess_page'>";
echo "<h1>Email Sent Successfully.</h1>";
echo "<p>Thank you. The following was sent to us. <br/><br/>$name<br/><br/>$email<br/><br/>$comments</p>";
echo "<a href='$link_address'>CLOSE THIS MESSAGE</a>";
echo "</div>";
} else echo "Error. Mail not sent";
}
}
if(!isset($_POST['contactus']) || $error != '') // Do not edit.
{
?>
<?php }
function isEmail($email) { // Email address verification, do not edit.
return(preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*#[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,12})$/",$email));
}
?>
As you can see, the $error from the inputs required should show up when the user does not enter in their $name, etc on the contact.php page where it says:
<?php echo $error; ?>
How can I have the $error(s) from the submit.php code show up on the contact.php page if a user does not fill in the required input fields?

Try this as your Submit.php added $_SESSION['error'] = $error; //if $error is not empty. Also removed extra php tag
<?php
ob_start();
session_start();
//fields
$link_address = 'contact'; // page to redirect to
$honeypot = '';
$error = '';
$name = 'Name';
$email = 'Email';
$comments = 'Message';
if(isset($_POST['contactus'])) {
$honeypot = $_POST['email_confirm'];
$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments'];
// honeypot
if($honeypot)
exit(1);
//error messages
if(trim($name) == 'Name') {
$error = '<div class="error_message">Need your Name</div>';
} else if(trim($name) == '') {
$error = '<div class="error_message">Need your Name</div>';
} else if(trim($email) == 'Email') {
$error = '<div class="error_message">Need your Email</div>';
} else if(trim($email) == '') {
$error = '<div class="error_message">Need your Email</div>';
} else if(!isEmail($email)) {
$error = '<div class="error_message">Need a valid email</div>';
} else if(trim($comments) == 'Message') {
$error = '<div class="error_message">A Message is required</div>';
} else if(trim($comments) == '') {
$error = '<div class="error_message">A Message is required</div>';
}
if (isset($error) && !empty($error)){
$_SESSION['error'] = $error; //SET errors for contact.php page to display
echo $error;
}else {
$_SESSION['error'] = '';
if(get_magic_quotes_gpc()) {
$comments = stripslashes($comments);
}
//email address
$address = "mail#example.com";
//email message
$e_subject = 'Web Message from: ' . $name . '.';
$e_body = "From: $name\nEmail: $email \r\n\nMessage:\n$comments\n\n\n";
$msg = $e_body . $e_content . $e_reply;
if(mail($address, $e_subject, $msg, "From: $email\r\nReply-To: $email\r\nReturn-Path: $email\r\n"))
{
//success html page response
echo "<div id='succsess_page'>";
echo "<h1>Email Sent Successfully.</h1>";
echo "<p>Thank you. The following was sent to us. <br/><br/>$name<br/><br/>$email<br/><br/>$comments</p>";
echo "<a href='$link_address'>CLOSE THIS MESSAGE</a>";

What should I put in my updating.php when I need to update users status if online or offline every 5 seconds?

Hi I've made a messaging feature,it displays the receivers of the message in an account, beside the receiver's name is a green or red dot, for online or offline, it is successful when I log in 2 accounts and messaged each other, when I open the first account, the other account is offline, when I open the second account, the other is online, what my problem is I want to update their status in every five seconds so that their dot will be accurate whenever they log out or log in. I have made a javascript and ajax below this page left-col.php and I've tried copying the whole code, putting it to updating.php but it did not work, what should be the appropriate data inorder to update user receiver status in every 5 seconds inside the updating.php? and also, does my the javascript and ajax needs a library to be included that's why it didn't work? Please help.

JavaScript/AJAX prints weirdly

My JavaScript/AJAX prints comments. It's all good, until I want to insert/get more than one comment. It duplicates itself. This feels like a nesting/missed parenthesis problem in my code, but I can't be able to find it...
My JS code:
$(document).ready(function(){
var url = 'comment-get.inc.php';
$.getJSON(url, function(data) {
$.each(data, function(index, item) {
var t = '';
t += '<div class="comment_holder" id="_'+item.id+'">';
t += '<div class="user"> <img src="src/img/page3_img7.jpg" alt="" class="img_inner fleft">';
t += '<div class="extra_wrapper">';
t += ''+item.username+'<br>';
t += ''+item.date+'<br>';
t += '<button class="button2" type="button" id="'+item.id+'">Delete</button>';
t += '</div></div>';
t += ''+item.message+'<br><br>';
t += '</div>';
$('.comment_holder').prepend(t);
add_delete_handlers();
});
});
add_delete_handlers();
$('#postButton').click(function(){
comment_post_btn_click();
});
function comment_post_btn_click()
{
//text in textarea with username, page and date
var _username = $('#postUsername').val();
var _page = $('#postPage').val();
var _date = $('#postDate').val();
var _message = $('#postMessage').val();
if(_message.length > 0)
{
//proceed with ajax callback
$('#postMessage').css('border', '1px solid #ABABAB');
$.post("comment-set.inc.php",
{
task : "comment-set",
username : _username,
page : _page,
date : _date,
message : _message
}
).success(
function(data)
{
//Task: Insert html into the div
comment_set(jQuery.parseJSON(data));
console.log("ResponseText: " + data);
});
}
else
{
//text in area is empty
$('#postMessage').css('border', '1px solid #FF0000');
console.log("Comment is empty");
}
//remove text after posting
$('#postMessage').val("");
}
function add_delete_handlers()
{
$('.button2').each(function()
{
var btn = this;
$(btn).click(function()
{
comment_delete(btn.id);
});
});
}
function comment_delete(_id)
{
$.post("comment-del.inc.php",
{
task : "comment-del",
id : _id
}
).success(
function(data)
{

});
}

$username = $_POST['username'];
$date = $_POST['date'];
$page = $_POST['page'];
$message = $_POST['message'];
require_once 'comments.php';

Picture of the problem (json_encode in the bottom of the picture containing 3 comments):
your comments div container has class .comment_holder so each time with new comment you prepend to all class's so create comment container with unique id an prepend to this. like this $('#comment_container').prepend(t); this with work.

PHP/HTML button picture change and script call

I have a page with buttons that a user clicks on.
When the button gets clicked I need it to change the image and call a php script to save the change.
I somehow can't get the button to do both, it changes the pic but won't call the php.

Fixed :
Changed the script function. Added a hidden div to be called to load the php which outputs nothing so stays invisible.
echo'<script>';
$count = count($result);

$TheId = $result[$i]['Id'];

jQuery textarea value just gives a "True", instead of value

Following code:
HTML-Form Textarea:
<textarea rows="5" cols="80" id="msg"></textarea><br>
jQuery sending the form:
$.ajax({
type: "POST",
url: "source/contact.php",
data: "email=" + $("#email").val() + "&msg=" + $("#msg").val() + "&phone=" + nr,
// Display Answer
success: function(answer){
alert(unescape(answer));
$("#form_contact")[0].reset();
},
// If sending failed: Display error message
error: function(){
alert("Form Sending Fail!");
}
});
I also tried:
$("textarea#msg").val()
Then here point that out with php:
$msg = $_POST['msg'];
And it always gives TRUE back (displayed as "1")
What am I doing wrong??
EDIT: PHP-File:
<?php
if(!isset($_POST['email']) || !isset($_POST['msg']) || !isset($_POST['phone'])){
echo "Access denied!";
exit;
}
$email = htmlentities($_POST['email']);
$msg = htmlentities($_POST['msg']);
$phone = htmlentities($_POST['phone']);
if($email != "" && $msg =! "" && $phone != ""){
echo "Danke f%FCr ihre Anfrage! \n Email: $email \n Msg: $msg \n Phone: $phone";
}else{
echo "Bitte alle Fleder ausf%FCllen!";
}
?>
try this,the $msg !=
<?php
if(!isset($_POST['email']) || !isset($_POST['msg']) || !isset($_POST['phone'])){
echo "Access denied!";
exit;
}
$email = htmlentities($_POST['email']);
$msg = htmlentities($_POST['msg']);
$phone = htmlentities($_POST['phone']);
if($email != "" && $msg != "" && $phone != ""){
echo "Danke f%FCr ihre Anfrage! \n Email: $email \n Msg: $msg \n Phone: $phone";
}else{
echo "Bitte alle Fleder ausf%FCllen!";
}
?>

JavaScript Ajax function returning error with status code 'OK'

I do not understand why this ajax request is returning an error even though the error status is OK (200), any thoughts? It seems like I am missing something very obvious but I have been tearing myself apart trying to find an answer! I am new to ajax and therefore have little experience with it! Thanks for the help.
This is my ajax request:
var dataString = $('#cform').serialize();
$.ajax({
type: "POST",
url: 'contact.php',
data: dataString,
dataType: 'json',
success: function (data) {
if (data.success == 0) {
var errors = '<ul><li>';
if (data.name_msg != '')
errors += data.name_msg + '</li>';
if (data.email_msg != '')
errors += '<li>' + data.email_msg + '</li>';
if (data.godaddyemail_msg != '')
errors += '<li>' + data.godaddyemail_msg + '</li>';
if (data.godaddyuser_msg != '')
errors += '<li>' + data.godaddyuser_msg + '</li>';
$("div#output").removeClass('alert-success').addClass('alert-error').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p> Could not complete your request. See the errors below!' + errors + '</p>');
}
else if (data.success == 1) {
$("div#output").removeClass('alert-error').addClass('alert-success').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p>You message has been sent successfully!</p>');
}
},
error: function (error) {
$("div#output").removeClass('alert-success').addClass('alert-error').show().html('<button type="button" class="close" data-dismiss="alert">x</button><p> Could not complete your request. The Function returned an error!</p>' + error.statusText); }
});
return false;
}
This is contact.php (where the request is sent to):
<?php
$send_email_to = "My Email";
$message = 'message';
$subject = 'subject';
function send_email($name,$email,$godaddyusername,$godaddyemail)
{
global $send_email_to;
if($message=='message')$message='';
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "From: ".$email. "\r\n";
$message = "<strong>Email = </strong>".$email."<br>";
$message .= "<strong>Name = </strong>".$name."<br>";
$message .= "<strong>GoDaddy Username = </strong>".$godaddyusername."<br>";
$message .= "<strong>GoDaddy Email = </strong>".$godaddyemail."<br>";
mail($send_email_to, $subject, $message,$headers);
return true;
}
function validate($name,$email,$godaddyusername,$godaddyemail)
{
$return_array = array();
$return_array['success'] = '1';
$return_array['name_msg'] = '';
$return_array['email_msg'] = '';
$return_array['godaddyuser_msg'] = '';
$return_array['godaddyemail_msg'] = '';
if($email == '')
{
$return_array['success'] = '0';
$return_array['email_msg'] = 'Email is required';
}
else
{
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email)) {
$return_array['success'] = '0';
$return_array['email_msg'] = 'Enter valid emmail.';
}
}
if($name == '')
{
$return_array['success'] = '0';
$return_array['name_msg'] = 'Name is required';
}
else
{
$string_exp = "/^[A-Za-z .'-]+$/";
if (!preg_match($string_exp, $name)) {
$return_array['success'] = '0';
$return_array['name_msg'] = 'Enter valid Name.';
}
}
if($godaddyusername == '')
{
$return_array['success'] = '0';
$return_array['godaddyuser_msg'] = 'GoDaddy Username is required';
}
if($godaddyemail == '')
{
$return_array['success'] = '0';
$return_array['godaddyemail_msg'] = 'GoDaddy Email is required';
}
else
{
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$godaddyemail)) {
$return_array['success'] = '0';
$return_array['godaddyemail_msg'] = 'Enter a valid GoDaddy email.';
}
}
return $return_array;
}
$name = $_POST['name'];
$email = $_POST['email'];
$godaddyemail = $_POST['gde'];
$godaddyusername = $_POST['gdu'];
$return_array = validate($name,$email,$godaddyusername,$godaddyemail);
if($return_array['success'] == '1')
{
send_email($name,$email,$godaddyusername,$godaddyemail);
}
header('Content-type: text/json');
echo json_encode($return_array);
die();
?>
That is because you have two undefined variables on your send_email() function.
Here you have this if statement..
if($message=='message')$message=''; // $message is not available inside this function.
and here
mail($send_email_to, $subject, $message,$headers); //$subject is also undefined.
