PHP

Everything is fine. No error is coming. Image name also stored in database perfectly but file is not moving in destination folder using move_uploaded_file function.

i don't know what to do. Please help me.

my code is:


link, $_POST['title']);
$body = mysqli_real_escape_string($db->link, $_POST['body']);
$category = mysqli_real_escape_string($db->link, $_POST['category']);
$author = mysqli_real_escape_string($db->link, $_POST['author']);
$tags = mysqli_real_escape_string($db->link, $_POST['tags']);

if(isset($_FILES['image'])){
$image = $_FILES['image']['name'];
$tmp_name = $_FILES['image']['tmp_name'];
$target= "images/";
}

if($title == '' || $body == '' || $category == '' || $author == ''){
$error = 'Please fill all required fields.';
}else{
$query = "INSERT INTO posts
(title, body, category, author, tags, image) VALUES('$title', '$body', $category, '$author', '$tags', '$image')";

$insert_row = $db->insert($query);


}
$upload = move_uploaded_file($tmp_name,$target.$image);
if ($upload){
$msg = "uploading file successfully.";
}else{
$msg = "there was a prob";
}
}
?>



select($query);
?>


<form role="form" method="post" action="add_post.php" enctype="multipart/form-data">
















</form>




What I have tried:

i have tried this solution by changing target directories but nothing happen.

$target = $_SERVER['DOCUMENT_ROOT'] . '/images/';
$target = $target . basename($_FILES['image']['name']);
