php form seleziona sottocartella caricamento file pdf

buongiorno in rete ho trovato uno script dove seleziono la sottocartella e carico il file pdf o doc ho provato a modificarlo ma mi da sempre errore sicuramente sbaglio qualcosa la directory è documenti/cartella nome utente chiedo aiuto grazie

<?php
				// Check if the form was submitted
				if($_SERVER["REQUEST_METHOD"] == "POST"){
					// Check if file was uploaded without errors
					if(isset($_FILES["file"]) && $_FILES["file"]["error"] == 0){
						// Get the subdirectory from the select element
						$subdir = $_POST["subdir"];
						// Set the destination path and filename
						$target_dir = "documenti/" . $subdir . "documenti/";
						$target_file = $target_dir . basename($_FILES["file"]["name"]);
						// Move the uploaded file to the destination
						if(move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)){
							echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded to " . $subdir . ".";
						} else{
							echo "Sorry, there was an error uploading your file.";
						}
					} else{
						echo "Error: " . $_FILES["file"]["error"];
					}
				}
				?>
				    <h6>carica documento</h6>
				 <?php
					$foldername = glob("documenti/*");
					?>

					<form action="admin.php" method="post" enctype="multipart/form-data">
					  <label for="select-cartella">Scegli la cartella di destinazione</label>
					  <select name="subdir" id="subdir">
					<?php foreach($foldername as $foldername): ?>
						<option value="<?= htmlspecialchars(basename($foldername)) ?>"><?= htmlspecialchars(basename($foldername)) ?></option>
					<?php endforeach ?>
