So on that logical statement below this text ( Also located in the code above) I'm wondering why when I echo out the javascript it's not changing the contents of the <p> element with the id of warning. I've tried looking everywhere for my answer and I'm sorry if this is a duplicate but any help would be appreciated...
if(!empty($username)){
echo "Username is not null";
}
else{
echo '<script type="text/javascript">document.getElementById("warning").innerHTML = "New text!";</script>';
}

"your basic problem is that it is executing, but none of your document has loaded yet. there is no element with the id of warning at the point your javascript is being loaded and executed" ~ Watcher

I want that when I click the submit button, other than sending the data through email, I want to send the data in a page where I have an INSERT script.
Here's the code of my page:

Same structure, but Ajax success response acts differently from previous version

Have been working on a form with Ajax and used to work on a version with no extras (css and so on) before. It worked all fine, data has been inserted successfully into the database and I have been able to show and hide two divs.
Now I used to apply it to the form I've been working on. It acts different from the previous version, so it's exactly the same (sure, changed some names, added some inputs), like no "success message" from the PHP-file, suddenly all data visible in the URL, the current form doesn't hide and shows the next one.
I can't understand the sudden change in behavior, took a look for mistakes, compared the codes, but have no idea. It seems to be such a small mistake that I don't spot it or something is wrong with the whole construction.
The current file is:

I used to work with the previous file I've worked with just to be sure that everything's right after a week of bug fixing.
Can somebody tell me where the problem is, probably why it is a mistake to avoid future problems like this?

The most obvious bug (aside from the SQL injection stuff mentioned above) is that
<button type="submit" will cause the form to submit normally via postback, unless you prevent it using script. Add event.preventDefault() to the first line of your "click" handler.
$("#submit").click(function(event){
event.preventDefault(); //prevent default postback behaviour
var size=$("#size").val();
//...etc
You're seeing the data in the URL because the form is posting normally (before the ajax has chance to run) and doing a GET because there's no other method specified in the form's markup, and GET is the default..

You may want to prevent the default behavior by passing the event to your click function and calling event.preventDefault().

How to pass Variable One page to another in php

I have created dynamic button and i need to pass the button ID to another page when my button is clicked. I have pass it but it didn't work
Please give any solution
Here is my code for dash.php:
<?php
session_start();
function dash () {
include 'config.php';
$sql = "SELECT RoomNumber FROM roommaster ";
if ($result = mysqli_query($db, $sql)) {
$str = '';
while ($row = mysqli_fetch_array($result)) {
// generate array from comma delimited list.
$rooms = explode(',', $row['RoomNumber']);
//create the dynamic button and set the value.
foreach ($rooms as $v) {
$str .= "<a href = 'booking.php'?btn='btn'><input type='button' name='b1' id='btn' value='" . $v . "' /></a>";
}
}
return $str;
} else {
echo "ERROR: Could not able to execute $sql. " . mysqli_error($db);
}
mysqli_close($db);
}
Here is my booking.php page:

while ($row = mysqli_fetch_array($result)) {
$RoomNumber = $row['RoomNumber'];
// $RoomType=$row['RoomType'];
// $Location=$row['Location'];
// $ChargesPerDay=$row['ChargesPerDay'];
}

mysqli_free_result($result);

Try to use $_GET instead of $_POST
if (isset($_GET['btn'])) {
$btn = $_GET['btn'];
echo $btn;
}

Try linking using a form. BUTTONID should be the value to pass. $str should be:
<form action='booking.php' method='POST'>
<input type='hidden' value='BUTTONID' name='bttn'>
<input type='submit' value='".$v."'>
</form>
And then get the value of the hidden field as you already did...
$if (isset($_POST['bttn'])) {
$btn = $_POST['bttn'];
echo $btn;
}

To pass little data from one page to another page use parameters in the URL as below is parameter with the value you want to pass to next page as:
Click Button
Then on the anotherpage.php use $_GET to get the value passed by the URL as:
$val = isset($_GET['parameter']) ? $_GET['parameter'] : NULL;
Then use the $val for other processing. I think this may can help you to understand how to pass data from one page to another page simply.

Try to use $_REQUEST by that you can get both GET and POST values.In booking.php print the array like below:
print_r($_REQUEST);
if (isset($_REQUEST['btn'])) {
$btn = $_REQUEST['btn'];
echo $btn;
}

It probably is overkill to use a custom library just to verify an email address. You could use https://secure.php.net/filter_var with the FILTER_VALIDATE_EMAIL filter. As far as I know, there is no real way of validating phone numbers.
That being said, your PHP error is that you do not close the if statement started on line 2. That causes an unexpected end, as the compiler still wants a closing accolade for your if statement.
EDIT: There is a very good SO answer for validating phone numbers.

There are a few things going on with the approach to your script.
Here is what I came up with that works on the script page.
<?php
if($_SERVER["REQUEST_METHOD"] == "POST") {
$name = trim($_POST["Name"]);
$email = trim($_POST["Email"]);
$phone = trim($_POST["Phone"]);
if( $name == "" || $email=="" || $phone==""){
$error = "Please fill name, email and phone";
}
}
else {
$error = "ERROR if someone came here directly";
}
?>
<html>
<body>
<?php if(isset($error)): ?>
<p><?php echo $error; ?></p>
<?php else: ?>
Welcome <?php echo $_POST["Name"]; ?><br>
Your email address is: <?php echo $_POST["Email"]; ?>
<?php endif; ?>
</body>
</html>
EDIT: To address the email validation you would use this to check if true or false:
This method checks if the email is NOT valid.
if(!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailError = "Invalid email";
}

Contact form does not validate on an iphone

The following contact form is not validating when submitting from an iphone...
It can be previewed here: loaistudio.com/contact
When I tried to submit the form without felling the fields, it opened a new blank page showing number 1 only on the top left side "which is not suppose to do at all" and actually sent the form empty... It does not do that on desktop.
I played around with the code trying to find the issue but no idea where is the problem! please help.
<?php
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
ob_start();
if(isset($_POST['name'])
&& isset($_POST['email'])
&& isset($_POST['message'])
&& isset($_POST['token'])){
if($_SESSION['token'] != $_POST['token']){
$response = "0";
} else {
$_SESSION['token'] = "";
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$to = "EMAIL GOES HERE";
$subject = "New Message From: $name";
$message = "$message";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";
$headers .= 'From: '.$email . "\r\n";
$mailed = ( mail($to, $subject, $message, $headers) );
if( isset($_POST['ajax']))$response = ($mailed) ? "1" :
"0"; else $response = ($mailed) ? "<h2>Success!</h2>" :
"<h2>Error! There was a problem with sending.</h2>";
echo $response;
}
} else {
echo "Form data error!";
}
ob_flush();
die();

you are adding jquery at the end of the html but you are using jquery before that, so javascript breaks with Uncaught ReferenceError: $ is not defined.
try moving this line to header:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

<script type="text/javascript">
$("#contactForm").submit(function(event) {
event.preventDefault();
$submit = $(this).find('button[id="submit"]');
var posting = $.post($(this).attr('action'), $('#contactForm').serialize());
posting.done(function(data) {
$('span.error').remove();
if (data == "1") {
$submit.text('Sent. Thank You!');
$submit.addClass("sent");
$submit.attr('disabled', 'disabled');
} else {
$submit.after('<span style="display: inline-block; padding: 15px 5px; color: #bd3d3d">Failed to send the message, please try again later.</span>');
$submit.text('Try Again');
}
});
});
</script>
This is code You have added AND THEN INCLUDED JQUERY, :) SO USE JQUERY IN HEADER !
