看起来像您的PHP代码有问题

<?php

if (is_uploaded_file($_FILES['uploaded_file']['tmp_name'])) {
    $uploads_dir = './';
    $tmp_name = $_FILES['uploaded_file']['tmp_name'];
    $pic_name = $_FILES['uploaded_file']['name'];
    move_uploaded_file($tmp_name, $uploads_dir.$pic_name);
}
else{
       echo "File not uploaded successfully.";
}
