Modal HTML
<!-- Name exist Modal -->
<div id="existNameModal" class="modal fade" role="dialog">

I am trying to get this Modal display when count(fname) in DB is more than 0. I tried everything but nothing worked.

From with Modal (form and modal both will be on same page)
<form class="form-horizontal" data-toggle="validator" method="post" role="form" id="enquiryForm">
<div class="form-group">
<label class="col-lg-2 control-label">Full Name :</label>
<div class="col-lg-8">
<input type="text" name="fname" class="form-control" id="inputFirstName" data-error="Please fill out this field." placeholder="Full Name" required>
<div class="help-block with-errors"></div>
</div>
<button type="button" class="btn btn-info" id="existName">Next</button>
</div>
</form>
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<div id="existNameModal"></div> //this is where message will show
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
In Ajax, you are using click function, better do it with change function on input and check the record if exist like
$('#inputFirstName').change(function(){
var fname = $(this).val();
//rest of code
});
The Ajax with click function
$('#existName').click(function(){
var fname = $('#inputFirstName').val();
var datas = "fname="+fname;
console.log(datas);
$.ajax({
url : "exist.php",
data : datas,
method : "POST"
})
});
Now to show modal and message if record exist
.done(function(exist){
console.log(exist);
if(exist.status=='error') {
$('#myModal').modal('show');
$('#existNameModal').html(exist.message);
}
});
The php exist.php
<?php
header('Content-Type: application/json');
$dbhost = "localhost";
$dbusername = "root";
$dbpassword = "";
$dbname = "gym";
$conn = mysqli_connect($dbhost, $dbusername, $dbpassword, $dbname) or die ("could not connect");
if($_POST['fname']){
$existName = $_POST['fname']; //escape the string
$sql = "SELECT count(fname) from enquiry where fname = '$existName' AND cmpId = '$idCompany'";
$result = mysqli_query($conn, $sql);
$row = mysqli_num_rows($result);
//print_r($row);
if(($row)>0) {
$response['status'] = "error";
$response['message'] = "<div class='alert alert-danger'>Record Already Exist</div>";
}
echo json_encode($response);
}
?>

How to write success message of form in bootstrap modal?

SOLVED
Ok, I solved the problem with AJAX but I had to delete my WordPress because it didn't work with it so later I will upload back by individual directory. Luckily I don't need it for my index. The working code is by CodexWorld. I hope I help someone who is helpless.
I am searching for solution all day but I don't get relevant solution anywhere. Other similar questions here are old, maybe there are fresh solution.
So I am using Bootstrap the first time (files are on the themes of Wordpress). I started to build a contact form in Modal and if I hit submit the window closes, I get the e-mail, but the success-message only shows if I reopen it. I tried every solution I found on internet.
I am not familiar with javascript and jquery, I don't know how to use it.
In the footer I implemented:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
In index there is the form with Modal:
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<form class="form-horizontal clearfix" id="contact-form" name="contact" role="form" method="post" action="index.php">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Küldj egy üzenetet</h4>
</div>
<div class="modal-body">
</div>
<div class="form-group">
<label class="col-sm-2 control-label">Itt landol</label>
<div class="col-sm-10">
<input class="form-control" id="disabledInput" type="text" placeholder="hello#kanizsaipatricia.hu" disabled>
</div>
</div>
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Név</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="name" name="name" placeholder="Minta János" value="<?php echo htmlspecialchars($_POST['name']); ?>">
<?php echo "<p class='text-danger'>$errName</p>";?>

</div>
</pop:form>
</div>
</div>
The php code behind the form:
if (isset($_POST["submit"])) {
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'Üzenetküldő űrlap';
$to = 'hello#kanizsaipatricia.hu';
$subject = 'Új üzenet formon keresztül';
$body = "Feladó: $name\n E-Mail: $email\n Üzenet:\n $message";
// Check if name has been entered
if (!$_POST['name']) {
$errName = 'Kérlek, add meg a neved!';
}
// Check if email has been entered and is valid
if (!$_POST['email'] || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$errEmail = 'Nem érvényes e-mail cím!';
}
//Check if message has been entered
if (!$_POST['message']) {
$errMessage = 'Nem írtál üzenetet.';
}
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage) {
if (mail ($to, $subject, $body, $from)) {
$result='<div class="alert alert-success noshadow">Elküldve.</div>';
} else {
$result='<div class="alert alert-danger noshadow">Sajnálom, hiba lépett fel az üzenet küldése közben. Próbáld újra!</div>';
}
}
}
I'm open minded for any solution in any language! Please help!

Please help

You can use while(){} method, so your script will be like this
$i = 0;
$res = array();
while($data = $_POST){
$res[$i] = $data;
$i++;
}
echo json_encode($res);

AJAX POST in same window instead of new

I tried to make a contact form within a bootstrap modal.
An alert should show up right after submitting the form in the modal.
It is working fine on my site which I use for testing.
But when I integrate the code in my main site the alert is shown as text in a new window. Same code. Different response. What could cause this behavior?

$encoded = json_encode($responseArray);
header('Content-Type: application/json');
echo $encoded;
}
else {
echo $responseArray['message'];
}
JS:
$(function () {
$('#contact-form').validator();
$('#contact-form').on('submit', function (e) {
if (!e.isDefaultPrevented()) {
var url = "contact.php";
$.ajax({
type: "POST",
url: url,
data: $(this).serialize(),
success: function (data)
{
var messageAlert = 'alert-' + data.type;
var messageText = data.message;
var alertBox = '<div class="alert ' + messageAlert + ' alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>' + messageText + '</div>';
if (messageAlert && messageText) {
$('#contact-form').find('.messages').html(alertBox);
$('#contact-form')[0].reset();
}
}
});
return false;
}
})
});

The action parameter in form tag action="contact.php" is forcing the page to refresh try using this as form tag :-
<form id="contact-form">
and change $(this).serialize() in your ajax post code to :-
$('#contact-form').serialize()

PHP Login not working

I have been working on a ban management system for a little bit but I encountered a error with the login system where it does not work
Live example:
http://lotus.pe.hu/lbans/index.php/

function register($username, $password) {

get_mysql()->query("insert into users (username, password) values ('$username', '$password')");
}
?>

Try to add this to this..
<?php
session_start(); //Transfer the session_start() here ..
require("api/api.php");
if( isset($_POST['username']) )
{
if( login( $_POST['username'], $_POST['password'] ) )
{
$_SESSION['username'] = $_POST['username'];
}
else
{
echo 'Invalid username/password';
}
}
require("header.php");
?>
