Create folder and upfile during same file

Question

I want to insert a news along with the image file in a single post, the problem is that I would like to create a folder with the news ID where the image will be stored. It’s happening that the Insert is working but the upload no, some light or easier way to do this?

$imagem = $_FILES['imagem'];

$sqlInsert = "INSERT INTO noticias (titulo,categoria,conteudo) VALUES (:titulo,:categoria,:conteudo)";
$stmt = DB::prepare($sqlInsert);
$stmt->bindParam("titulo", $titulo);
$stmt->bindParam("categoria", $categoria);
$stmt->bindParam("conteudo", $conteudo);
$stmt->execute();

$ultimoid = DB::lastInsertId();
$dir = "../imagens/$ultimoid";
$pasta = mkdir("$dir", 0775);
if(is_dir("$dir")){
  if($arquivo != "none") {
    if (copy($_FILES['imagem']['tmp_name'], $dir . $_FILES['imagem']['name'])) {
    $arquivo1 = $_FILES['imagem']['name'];
    $sqlInsert = "UPDATE noticias SET imagem=:imagem WHERE idnoticia=$ultimoid";
    }
}

remembering that I made a summary of the code only with the parts that I believe is where is giving problem, any doubt put the whole code

Answer 1

You have placed the attribute in the HTML: enctype="multipart/form-data", it is necessary to upload via POST.

Check here for an example:

<form method="post" action="salvar-alguma-coisa.php" enctype="multipart/form-data">
    <input type="file" name="arquivo">
    <input type="submit" value="enviar">
</form>
