循环遍历“move_uploaded_file”文件

Question

我正在尝试将多个pdf文件上传到我网站的文件夹中。它只上传了pdf中的第一个pdf，所以我试图使用一个数组，但它给出了一个错误。

$target = "../media/covers/".basename($_FILES['image']['name']);
$pdf_target = "../media/pdfs/".basename($_FILES['pdf_file']['name'][0]);
// I use [0] above to access the string

foreach($pdf as $idx){
        if (isset($_POST["upload"])) {
            if(move_uploaded_file($_FILES['image']['tmp_name'], $target) 
            && move_uploaded_file($_FILES['pdf_file']['tmp_name'][$idx], $pdf_target)){
                $msg = "image uploaded";
            }  else {
                $msg = "There was a problem uploading image";
            }
        }
}

我希望所有文件都上传到文件夹“../media / pdfs /”
