Modal validation using Bootstrap Modal - PHP

PHP Script & Validation:
function SampleInput($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
if (isset($_POST['RegisterClient'])) {
$file = $_FILES['avatar']['name'];
$file_location = $_FILES['avatar']['tmp_name'];
$folder = "../Public/img/uploads/profile-picture/";
$new_file_name = strtolower($file);
$final_file = str_replace(' ', '-', $new_file_name);
$name = htmlspecialchars(trim($_POST['name'], ENT_QUOTES));
$username = htmlspecialchars(trim($_POST['username'], ENT_QUOTES));
$email = htmlspecialchars(trim($_POST['email'], ENT_QUOTES));
$password = htmlspecialchars(trim($_POST['password'], ENT_QUOTES));
$cpassword = htmlspecialchars(trim($_POST['cpassword'], ENT_QUOTES));
$role = htmlspecialchars(trim($_POST['role'], ENT_QUOTES));
if (move_uploaded_file($file_location, $folder.$final_file)) {
$image = $final_file;
}
if(empty($_POST['name']) || empty($_POST['username']) || empty($_POST['password']) || empty($_POST['cpassword']) || empty($_POST['role'])) {
$error = "All fields are required!";
} else {
$name = SampleInput($_POST['name']);
$username = SampleInput($_POST['username']);
$password = SampleInput($_POST['password']);
$cpassword =SampleInput($_POST['cpassword']);
$role = SampleInput($_POST['role']);
if (!preg_match('/^[a-zA-Z0-9\s]+$/',$name && $username && $password && $cpassword && $role)) {
$error = "Only letters and white space allowed";
}
}
$stmt = $db->prepare("INSERT INTO clients(name, username, email, password, avatar, role, registration_date) VALUES (:name, :username, :email, :password, :avatar, :role, NOW())");
$stmt->execute(array(
'name' => $name,
'username' => $username,
'email' => $email,
'password' => $password,
'avatar' => $image,
'role' => $role

$success = 'Registered!';

<button type="submit" name="RegisterClient" class="btn btn-primary">Create</button>
</div>
</div>
</form>
</div>
</div>
I don't know where the problem is, I want the modal to remain open even if the problem or form has been submitted successfully. Now, with this code, if there is a problem with the submit form, the modal shuts down and if we open it again, the user can see error messages. Where am I wrong?

After a whole day, I resolve an issue with this.
$('#myModal').modal({
backdrop: 'static',
keyboard: false
})
With this code written above, a modal will be closed only if the user clicks on the close button. With this code, you disabled the close modal by pressing the ESC button on the keyboard.

Input validation - stop form from being clear out

I tried to create a sign up form where I need to validate if the the information entered is already exists in the database.
The code runs fine and can detect if the anything are already exists in the database.
The problem is it will clear all the form when it detects anything exists in database.
For example in below picture I try to input an email that already exists in database but in the second photo, all the form fields are clear out
Is there any ways to prevent the form from being cleared out? Its not convenience for user to re-fill the form again.
Below is my code.
<?php
include 'include/header.php';
include ('admin/include/dbcon.php');
?>
<script type="text/javascript">
$(document).ready(function() {
$("#inputState3").on('change', function() {
var val2 = $("#inputState3").val();
$.ajax({
url: "stdsec.php",
method: "post",
data: 'myvalue=' + val2
}).done(function(sec) {
$('#inputState1').html(sec);
})
})
});
</script>

PHP Captcha validate and send the user to one specific page

I have a one page php webmail script.
PHP script code below:
<?php
function validEmail($email){
if (!preg_match("/^[^#]{1,64}#[^#]{1,255}$/", $email)) {
return false;
}
$email_array = explode("#", $email);
$local_array = explode(".", $email_array[0]);
for ($i = 0; $i < sizeof($local_array); $i++) {
if (!preg_match("/^(([A-Za-z0-9!#$%&'*+\/=?^_`{|}~-][A-Za-z0-9!#$%&'*+\/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i])) {
return false;
}
}

$code=rand(1000,9999);
$_SESSION["code"]=$code;
$im = imagecreatetruecolor(50, 24);
$bg = imagecolorallocate($im, 22, 86, 165);
$fg = imagecolorallocate($im, 255, 255, 255);
imagefill($im, 0, 0, $bg);
imagestring($im, 5, 5, 5, $code, $fg);
header("Cache-Control: no-cache, must-revalidate");
header('Content-type: image/png');
imagepng($im);
imagedestroy($im);
?>
and validate code will be: validate.php
<?php
session_start();
if(isset($_POST["captcha"])&&$_POST["captcha"]!=""&&$_SESSION["code"]==$_POST["captcha"])
{
echo "Correct Code Entered";
//Do you stuff
}
else
{
die("Wrong Code Entered");
}
?>

calling javascript function from php form submit

Good day, will anybody be willing to help me out here. I have this code:
<form id="form_advanced_validation" method="POST" action="">
<div class="row clearfix">
<div class="col-md-10">
<div class="form-group form-float">
<div class="form-line">
<input type="password" class="form-control" name="oldPass" required>
<label class="form-label">Old Password</label>
</div>
</div>
</div>
</div>
<div class="row clearfix">
<div class="col-md-10">
<div class="form-group form-float">
<div class="form-line">
<input type="password" class="form-control" name="newPass" required>
<label class="form-label">New Password</label>
</div>
</div>
</div>
</div>
<div class="row clearfix">
<div class="col-md-10">
<div class="form-group form-float">
<div class="form-line">
<input type="password" class="form-control" name="confPass" required>
<label class="form-label">Confirm Password</label>
</div>
</div>
</div>
</div>
<button class="btn btn-primary waves-effect" type="submit" name="sChanges">SUBMIT</button>
When submit button will be clicked, it will process the change password procedure, this is the code:
if (isset($_POST['sChanges'])) {
$dbC = new imsFunction();
$oldPasswrd = $dbC->txtInput($_POST['oldPass']);
$newPasswrd = $dbC->txtInput($_POST['newPass']);
$confPasswrd = $dbC->txtInput($_POST['confPass']);
$idNumber = $_SESSION['eID'];
if ($newPasswrd <> $confPasswrd) {
$_SESSION['passConfirm'] = FALSE;
echo '<script language="javascript">';
echo 'window.location = "change_Passwd.php";';
echo '</script>';
} else
$dbQry = $dbC->sRowQry('Select * From tbl_endUser Where id_number = ? and id_key = ?',[$idNumber, $oldPasswrd]);
if ($dbQry->rowCount() > 0) {
$changePass = $dbC->qryExec('Update tbl_endUser Set id_key=? Where id_number=?',[$newPasswrd, $idNumber]);
$_SESSION['passChange'] = TRUE;
echo '<script language="javascript">';
echo 'window.location = "change_Passwd.php";';
echo '</script>';
} else {
$_SESSION['wrongPass'] = FALSE;
echo '<script language="javascript">';
echo 'window.location = "change_Passwd.php";';
echo '</script>';
}
$dbC->disConnect(); }
What I want to do is when "$_SESSION['passChange']" has been set, I would like to call this javascript function:
function showSuccessMessage() {
swal("Good job!", "Password has been changed!", "success");}
I tried:
if (isset($_SESSION['passConfirm'])) { echo '<script type="javascript"> showSuccessMessage(); </script>'; }
but nothing happened.. Please guys, help me.

Don't forget to use session_start(); at beginning of each page.
Before calling the function, just use echo $_SESSION['passConfirm']; to ensure the session is set.
Now correct your code based on above 2 things and check

Trouble getting input form to return 'success' message and to reset

I have created a form based on the bootstrapious.com contact form tutorial. In my case I have changed it to populate a mysql database. Filling out the form and submitting it does get the information correctly in the database, but does not return a 'success' message or reset the form. I think the problem is in my javascript but am not sure. I would appreciate any help. Thanks
