尽管路径和现有文件正确，move_uploaded_file仍无法正常工作

Question

I'm really struggling with an issue relating the move_uploaded_file function of php.

The path should be correct, but see yourself:

$imgDir     = "../img/".$CATEGORY;
$fileName   = $_FILES['image']['name'];
$maxsize    = 800;
$compQuality= 75;
if(!is_dir($imgDir)) {
    mkdir($imgDir.'/tn', 0777, true);
    chmod($imgDir, 0777);       
    chmod($imgDir, 0777);
}

$imgDir     = $imgDir."/";
$imgTnDir   = $imgDir."tn/";

I have also tested it by echo-ing everything and it seems to work, but when it comes to the move_uploaded_file it still does not work, even though I test if the file really exists:

if(file_exists($imgDir.$fileName)) {
    $status = "The file ".$fileName." already exists, please choose a different title.";
} 

if(!move_uploaded_file($_FILES['image']['tmp_name'], $imgDir.$fileName)) {
    $status = "File upload failed, sorry.";
}   

if(!empty($status)) { 
    echo $status;
    exit();
}   

I hope that someone can help me. If you want I can print anything out you need or give you more snippets of the code. The var $_FILES['image']['tmp_name'] does not only exist, but has a proper name by the way.

Also I have checked the php.ini and both uploading is allowed and the size is surely set high enough.

Thank you in advance.

make sure that you have the right path in $imgDir. You can try:

if(!is_writable($imgDir)) { exit('CANNOT_WRITE_IN_DIR'); }

and also you can use an absolute path, like this:

$imgDir = __DIR__ . "/../img/".$CATEGORY;
