Form Data Isn't Displayed In Database - php

On the website, there is a form where admins can create accounts these accounts can be user or admin, currently on the website when I fill in the form fields and post the form data to the form processing file, something happens, I've been looking around but I can't seem to find any solution to this.
<?php
session_start();
if (!isset($_SESSION['accessRights']) || $_SESSION['accessRights'] == false) {
header("location:../../index.php");
}
if (!isset($_SESSION['accessRights']) || $_SESSION['accessRights'] == "user") {
header("location:../../index.php");
}
?>

I want something like this...
when I click on <input type="submit" of signup the signup() function from functions.php should work. But I don't know how to do it.
If I remove function signup(){} from functions.php and try without function then in url signup.php is replaced by functions.php and page is blank and no data is inserted in mysql localhost.
In 'config.php' file
<?php
$con = mysqli_connect("localhost","root","","get-viewed");
?>
Database name, Table name and field name are perfect I have double checked it.

The form action correctly point to function.php and the webserver execute it.
The result is blank because nothing in function.php get executed.
you defined function signup() but you don't call it
add signup(); as last code line, just before php closing tag ?>
Note 1: you can extract the code from the signup function, since it does not add any advantage.
Note 2: if the php closing tag is the last code line in the file (no html follow) you should omit, it is a good practice to avoid unwanted output.
This is a must once you start to use frameworks, otherwise header errors will popup

Thanks for helping me I have solved my question.
I updated functions.php
<?php
include 'config.php';
function signup() {
$uname = $_POST['uname'];
$email = $_POST['email'];
$password = $_POST['password'];
$cpassword = $_POST['cpassword'];
if($password == $cpassword) {
$hash = password_hash($password, PASSWORD_DEFAULT);
$insert = "INSERT INTO `users`(`user_name`, `email`, `password`) VALUES ('$uname','$email','$hash')";
$result = mysqli_query($con, $insert);
if ($result) {
echo '<script>alert("Your account has been successfully created.")</script>';
}
}
else {
echo '<script>alert("Passwords do not match!");location.replace("signup.php");</script>';
}
}
function login(){
if (isset($_POST['login'])) {
echo '<script>alert("login")</script>';
}
}
if (isset($_POST['signup'])) {
signup();
}
else {
login();
}
Now it is working perfectly as I wanted.

Please use array_key_exists() function to check if the key email and phone exist in your variable.
Something like...
if (array_key_exists("email", $row)) {
if ($row['email'] == $email) {
$errorMsg[] = "Adres e-mail jest już zajęty";

Displaying query result on same page PHP

I am currently using a PHP script to add a record into my database, this works properly after some debugging. When the script runs, it opens a new page with the query output.
I'd like to display the query output on the same page that executes the query, at the top of the page, under my navbar.
Below is my current page.
This is the desired result.
The relevant code of the HTML page:
<form name="registration" action="addKlant.php" target="_blank" method="post">
<h3><i class="fa fa-plus-circle"></i> Klant toevoegen</h3>
<div class="form-input">
<label><i class="fa fa-info-circle"></i> Naam</label>
<input type="text" name="klantNaam">
</div>
<div class="form-input">
<label><i class="fa fa-info-circle"></i> Soort klant</label>
<select class="" name="klantSoort">
<option value="">Bedrijf</option>
<option value="">Particulier</option>
</select>
</div>
<div class="form-input">
<label><i class="fa fa-info-circle"></i> Telefoonnummer</label>
<input type="number" name="klantTel">
</div>
<div class="form-input">

</form>
addKlant.php
<?php
require('db.php');
$stmt = $con->prepare('INSERT INTO `klanten` (klant_naam, klant_soort, klant_telefoon, klant_email, klant_straat, klant_postcode, klant_plaats) VALUES (?, ?, ?, ?, ?, ?, ?)');
if($stmt) {
$klant_naam = $_POST['klantNaam'];
$klant_soort = $_POST['klantSoort'];
$klant_telefoon = $_POST['klantTel'];
$klant_email = $_POST['klantEmail'];
$klant_adres = $_POST['klantAdres'];
$klant_postcode = $_POST['klantPostcode'];
$klant_plaats = $_POST['klantPlaats'];
$stmt->bind_param('ssissss', $klant_naam, $klant_soort, $klant_telefoon, $klant_email, $klant_adres, $klant_postcode, $klant_plaats);
$stmt->execute();
$con->close();
echo "Klant is toegevoegd, je kan deze pagina nu sluiten.";
}
?>
I was thinking about using something like if($_POST)? But I do not know how to implement it exactly.
It does not matter if the page refreshes to add the output, but I would like to keep it to PHP and not use JS (of course, if it is possible with only PHP).
Any tips are greatly appreciated.
EDIT: Edited my code with some help from #SloanTrasher
<?php
if($_POST['submit'] == 'Klant toevoegen') {
require('db.php');
$stmt = $con->prepare('INSERT INTO `klanten` (klant_naam, klant_soort, klant_telefoon, klant_email, klant_straat, klant_postcode, klant_plaats) VALUES (?, ?, ?, ?, ?, ?, ?)');
if($stmt) {
$klant_naam = $_POST['klantNaam'];
$klant_soort = $_POST['klantSoort'];
$klant_telefoon = $_POST['klantTel'];
$klant_email = $_POST['klantEmail'];
$klant_adres = $_POST['klantAdres'];
$klant_postcode = $_POST['klantPostcode'];
$klant_plaats = $_POST['klantPlaats'];
$stmt->bind_param('ssissss', $klant_naam, $klant_soort, $klant_telefoon, $klant_email, $klant_adres, $klant_postcode, $klant_plaats);
$stmt->execute();
$con->close();
}
}
?>

I'm assuming that the HTML form is not part of addKlant.php?
In which case, once you've processed the form, you might want to redirect to the page with the HTML form, and pass an item in the querystring with some sort of variable to show the query has run.
i.e.
// ... after your form processing
$con->close();
header("Location: htmlpage.php?queryresult=ok");
exit;
and then in the HTML form page:
<?php if ($_GET['queryresult'] == 'ok') print "query ran okay"; ?>
I don't know what the result of the query might look like - if it is encodable within a url, you can pass this whole response, ie.
header("Location: htmlpage.php?queryresult=" . urlencode( $queryresultstring ));

i dont know why the isset function is not working when i submit

I am trying to create a registration form with validation.i used some bootstrap for the front end design then Mysql database along with php.
when I click to submit the registration form, it does not validate the field values.please, someone, tell me what's wrong with this.Also, it's not showing the errors. I don't know why this is not working.
Thank you in Advance.

Just change this line from
<button type="button" name="submit" class="btn btn-primary btn-lg btn-block login-button">Register</button>
to
<button type="submit" name="submit" class="btn btn-primary btn-lg btn-block login-button">Register</button>
You have used button so form is not submitted. Change it to submit type
EDIT
Note: please start using PDO or mysqli
Please check below point:
1) You have used test_input() but not defined in your shown code.
2) Your query have extra , after confirm_password.
3) Insert query will not work. There were some errors:
$query = "INSERT INTO customer (name,user_name, password,confirm_password, email) VALUES ('
$name', '$username', '$password', '$cpassword', '$email')";
4) No need to store confirm_password

Database
<?php
$servername = "localhost";
$username = "root";
$password = "";
$database = "stackoverflow";
// Create connection
$conn = new mysqli($servername, $username, $password,$database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
session_start();
?>
Change the Register button like this
<div align="left" class="form-group ">
<button type="submit" name="submit" class="btn btn-primary btn-lg btn-block login-button">Register</button>
</div>
test_function
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
Full PHP
<?php
if (isset($_POST['submit']))
{
$name = $_POST['name'];
$username = $_POST['user_name'];
$email = $_POST['email'];
$password = $_POST['password'];
$cpassword = $_POST['confirm_password'];
$slquery = "SELECT * FROM customer WHERE email = '$email'";
$selectresult = mysqli_query($conn,$slquery);
if(empty($_POST['name']))
{
$nameErr='Enter Your Name!';
}
else
{
$user = test_input($_POST['name']);
if(!preg_match('/^[a-zA-Z0-9#_]*$/',$user))
{
$nameErr=' Re-Enter Your Name! Format
Incorrect!( only alpha, numbers,#_ are allowed)';
}

if(empty($_POST['password']))
{
$passErr='Enter Your Password!';
}
else
{
$user = test_input($_POST['password']);
if(!preg_match('/^[a-zA-Z0-9#_]*$/',$password))
{
$passErr='Invalid Format! Re-Enter Password!';
}
}
if (mysqli_num_rows($selectresult)>0)
{
echo 'email already exists';
}
elseif($password != $cpassword){
$msg = "passwords doesn't match";
}
else{
var_dump($name.$email.$username.$password.$cpassword);
$query = "INSERT INTO customer(name,email,user_name,
password,confirm_password) VALUES ('

PHP Doesn't post my form values

I've been scratching my head for a hour now and can't figure out why php doesn't post my form values.
Code
<!-- Login -->
<div class="login__block toggled" id="l-login">
<div class="login__block__header">
<i class="zmdi zmdi-account-circle"></i>
Hi there! Please Sign in
<div class="actions login__block__actions">

<ul class="dropdown-menu pull-right">

<li><a data-block="#l-forget-password" href="#">Forgot password?</a></li>
</ul>
</div>
</div>
</div>
<div class="login__block__body">
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="text" class="form-control" name="email">
<label>Email Address</label>

</div>
<div class="form-group form-group--float form-group--centered form-group--centered">

<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</div>
<?php
if(isset($_POST['login'])) {
if(isset($_POST['email']) && isset($_POST['password']) &&
is_string($_POST['email']) && is_string($_POST['password']) &&
!empty($_POST['email']) && !empty($_POST['password'])) {
$email = stripslashes(strip_tags($_POST['email']));
$password = md5($_POST['password']);
$stmt = $pdo->prepare('SELECT * FROM users WHERE UserEmail = :UserEmail');
$stmt->bindParam(':UserEmail', $email);
$stmt->execute();
if($stmt->rowCount() > 0) {
$stmt = $pdo->prepare('SELECT * FROM users WHERE UserEmail = :UserEmail AND UserPassword = :UserPassword');
$stmt->execute(array(':UserEmail' => $email, ':UserPassword' => $password));
if($stmt->rowCount() > 0) {
$row = $stmt->fetch();
$UserLevel = $row['UserLevel'];
if($UserLevel == 'banned') {
$display->ReturnError('Your account has been suspended.');
return false;
}
$UserID = $row['UserID'];
$time = time();
$IPAddress = $_SERVER['REMOTE_ADDR'];
$_SESSION['auth'] = $UserID;
$stmt = $pdo->prepare('INSERT INTO logs (LogUserID, LogDate, LogIPAddress) VALUES (:LogUserID, :LogDate, :LogIPAddress)');
$stmt->execute(array(':LogUserID' => $UserID, ':LogDate' => $time, ':LogIPAddress' => $IPAddress));
$display->ReturnSuccess('You was successfully logged in.');
$settings->forceRedirect('index.php', 2);
} else {
$display->ReturnError('Invalid user credentials.');
}
} else {
$display->ReturnError('User with these credentials does not exists.');
}
}
}
?>
</div>
Note that I'm very new to PHP and it would mean the world to me if you could help me out! Thank you.

Submit Button only works when it is inside form tag.
Your code does not have any form tag
Try this
<form action="" >
<!-- Login -->
<!--your code here -->
</form>

add form attributes like this
<div class="login__block__body">
<form action="url which will process form" method="POST">
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="text" class="form-control" name="email">
<label>Email Address</label>
<i class="form-group__bar"></i>
</div>
<div class="form-group form-group--float form-group--centered form-group--centered">
<input type="password" class="form-control" name="password">
<label>Password</label>
<i class="form-group__bar"></i>
</div>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</form>
</div>

All <input> tags must be within the <form> tags.
<form action="" method="post"> //Submits form to same page
<input/>
<input/>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</form>
When you "submit" this form, it will POST all of the input values within the form, which you retrieve from the $_POST['name_of_input'] variables
I would recommend learning HTML before PHP.
