I can't view the database content on php page
I want to fetch data using ID
thats the code :
<?php
//connect with database
$servername = "localhost";
$userdbname = "root";
$dbpassword = "";
$dbname = "users";
$usid = 0;
$docname = '';
$conn = new mysqli($servername, $userdbname, $dbpassword, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM users WHERE id=".$usid;
if ($conn->query($sql) === TRUE) {
$conn->close();
$URLS = array();
while ($row = $result->fetch_array()) {
$docname= $row['docname'];
}
header("Location:Editeform.php");
}
?>
This is the form I am trying to view the data in :
<div class="form-group">
<input type="text" class="form-input" name="docname" id="name" placeholder="Your Name" value="<?php echo $users['docname']; ?>" />
</div>

I have made an example how it could look with PDO (as i see you are just starting and i suggest to learn PDO as its not that hard)
This way you also are safe from SQL injections.
$host = '127.0.0.1';
$db = 'test';
$user = 'root';
$pass = '';
$charset = 'utf8mb4';
$usid = 0;
$docname = '';
$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$options = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
try {
$pdo = new PDO($dsn, $user, $pass, $options);
} catch (\PDOException $e) {
throw new \PDOException($e->getMessage(), (int)$e->getCode());
}
$stmt = $pdo->query("SELECT * FROM users WHERE id=?");
$stmt->execute([$usid]);
$row = $stmt->fetch();
$docname = $row['docname'];
echo '
<div class="form-group">
<input type="text" class="form-input" name="docname" id="name" placeholder="Your Name" value="'.$docname.'" />
</div>';
P.S. I have not tested it so fill your details and give it a try!
