업로드 에러 질문입니다 채택완료

안녕하세요

업로드가 도저히 되지 않아 인터넷에서 코드를 통째로 긁어서 쓰는데도 안되네여;;;

$target_dir = "data/evidence_img/"; $target_file = $target_dir . basename($_FILES["co_img"]["name"]); $uploadOk = 1; $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); // Check if image file is a actual image or fake image if(isset($_POST["submit"])) {     $check = getimagesize($_FILES["co_img"]["tmp_name"]);     if($check !== false) {         echo "File is an image - " . $check["mime"] . ".";         $uploadOk = 1;     } else {         echo "File is not an image.";         $uploadOk = 0;     } } // Check if file already exists if (file_exists($target_file)) {     echo "Sorry, file already exists.";     $uploadOk = 0; } // Check file size if ($_FILES["co_img"]["size"] > 5000000) {     echo "Sorry, your file is too large.";     $uploadOk = 0; } // Allow certain file formats if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {     echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";     $uploadOk = 0; } // Check if $uploadOk is set to 0 by an error if ($uploadOk == 0) {     echo "Sorry, your file was not uploaded."; // if everything is ok, try to upload file } else {     if (move_uploaded_file($_FILES["co_img"]["tmp_name"], $target_file)) {         echo "The file ". basename( $_FILES["co_img"]["name"]). " has been uploaded.";     } else {         echo "Sorry, there was an error uploading your file.";     } }

echo $_FILES["co_img"]["error"]; ?>

이렇게 사용중인데

해당 폴더안에 이미지가 업로드 되지 않습니다

Sorry, there was an error uploading your file.

move_uploaded_file 여기서 처리가 되지 않아 위에 문구가 뜨는것 같은데

도저히 해결이 안되네요;;;

도움 부탁드립니다
