what must i do with that script ?
thank you for you help :) and sorry for my bad english ;)

Use some thing like this:
<input type="email" name="email" class="form-control" placeholder="Masukan Alamat Email Anda" pattern="^[A-Za-z#.0-9]*$" title="Masukan E-Mail yang Valid(Aktif)" value="<?php isset($_REQUEST['email']) ? $_REQUEST['email'] : '' ?>" required />
this
value="<?php if(isset($_REQUEST['email'])) { echo $_REQUEST['email']; } ?>"
will retain value in the textbox on unsuccessful processing.

Take a look to this example may help you PHP Form validation

How to make PHP register errors go underneath their dedicated input boxes

I'm just wondering if anyone knows how to make the errors shown on this screenshot: https://imgur.com/a/eaTVR9g go underneath their dedicated input boxes like shown on this image: https://imgur.com/a/Sb1AfUj If anyone is kind enough to do it for me I would greatly appreciate it. Thank you!

You can organize the array keys to reflect the fields they relate to, IE:
if (strlen($username) < 3) {
$errors['username'][] = 'Your username must be at least 3 characters in total.';
}
and then on the display side you can use said keys to identify what errors belong to what field, IE:
<div class="field">
<label class="label">Username</label>
<div class="control has-icons-left">
<input class="input" name="username" type="text" id="username" maxlength="15" autocomplete="off" placeholder="Enter a username">
<span class="icon is-small is-left"><i class="fas fa-user"></i></span>
<p id="username_message">
<?php if (isset($errors['username'])): ?>
<?php foreach($errors['username'] as $error): ?>
<?= $error ?> <br/>
<?php endforeach; ?>
<?php endif; ?>
</p>

<?php

You store the value of $_POST['m_username'] in $_SESSION['user'], but then query for id_member = $_SESSION['user']...
$get_ip = getIpUser();
$id_member = "select * from tbluser where id_member = '$get_ip'";
$username_member = $_POST["m_username"];
...
$_SESSION["user"] = $username_member;
and
$id_member = $_SESSION['user'];
$get_member = "SELECT * FROM tbluser where id_member = '$id_member'";

how to validate html form in another php file and get back errors to the html form file

I've created a signup.php file for html form and signup_form_handler.php for validate the html form. Before create a separate file for validation I tried to validate the html form in the same file (signup.php) and I succeeded. After I separate the validation part into another file I have this problem. How can i get back the validation errors from signup_form_handler.php to the html form file (signup.php) .

in signup_form_handler.php
SESSION_START();
SESSION['data'] = $data;
in signup.php
SESSION_START();
print SESSION['data'];

Well you can save the error message in a session variable. In case of error you can redirect the user back to the signup.php page. Try following code in signup_form_handler.php. It should go at the bottom of the first If clause
$error_message = "";
if ($nameErr != "") $error_message = $nameErr;
if ($emailErr != "") $error_message = $emailErr;
if ($checkErr != "") $error_message = $checkErr;
if ($passErr != "") $error_message = $passErr;
if ($cpassErr != "") $error_message = $cpassErr;
if ($error_message != "") {
$_SESSION['error_message'] = $error_message;
header("Location: " . $error_message);
exit;
}
Also add the line : session_start(); at the top of the signup_form_handler.php and signup.php.
In signup.php file, you have to add the lines:
if (isset($_SESSION['error_message']) && $_SESSION['error_message'] != "") {
echo $_SESSION['error_message'];
unset($_SESSION['error_message']);
}

How to Populate fields using URL parametres in using php and mysql

I have a URL link, and upon clicking the link, it has to populate the fields as soon as the page is opened, below is the URL link and the form that has to be populated with few fields,fields such as names, idocode and email has to be populated, and the rest by the user and the submit button has no effect, what am I doing wrong,
URL: 'http://www.domain.com/register/registration.php?token=$token&stud_id=stud_id'
<?php
error_reporting(1);
session_start();
include 'includes/connect.php';
$student_id = $_GET["id"];

$_SESSION['token'] = $token;
if (isset($_GET["id"]) && isset($_GET["tk"])) {
$sql = "SELECT * FROM student WHERE student_id=" . $student_id . " and token='" . $token . "'";
$stmt = $pdo->prepare($sql);
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_ASSOC);

$sql = "UPDATE student SET first_name=:first_name, middle_name=:middle_name, last_name=:last_name WHERE student_id=:student_id";
$stmt->bindValue(':first_name', $first_name);
$stmt->bindValue(':middle_name', $middle_name);
$stmt->bindValue(':last_name', $last_name);
$stmt->bindValue(':student_id', $student_id);
$result = $stmt->execute();
} else {
}
}
if ($_POST["Submit"] == "Submit") {

if (isset($validate) && $validate) {

if ($_POST["password"] != $_POST["confirm_password"]) {
echo 'passwords do not match';
}
$result1 = $stmt->execute();
//echo $result ;exit;
if ($result1) {
echo '<div><p class="text-success">Created Successfully!</p></>';
}
clear_session();
}
}

I'm trying to make a delete button for my contacts within the addressbook. but everytime I click "Contact verwijderen" the webpage resets it self and the contact won't be deleted. Could anyone help me to fix this?

You input is a text input and you don't have a form asociated with it,create one and change the type of submit to submit
<form action="delete_contact.php" method="post">
//other inputs
<input type="submit" name="delete_contact" class="btn btn-succes" value="Contact verwijderen">
</form>

You are mixing MySQL and MySQLi functions:
mysqli_query ($query);
if (mysql_affected_rows() == 1)
You cannot mix MySQL with MySQLi, your code should be:
mysqli_query ($query);
if (mysqli_affected_rows($conn) == 1)

Add a normal link to delete the contact, you don't need a form.
<a href="delete_contact.php?id=<?php echo $id ?>">
Contact verwijderen
</a>
