move_uploaded_file error php won't upload to filepath - php

Question

I'm writing a script to upload user input and images to a place in my file system (currently on a different server).
I get an error
move_uploaded_file(images//test.pdf): failed to open stream: Permission denied in ..
$dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_USERNAME, DB_USERNAME, DB_PASSWORD);
$title = $_POST["title"];
$authors = $_POST["authors"];
$description = $_POST["description"];
$price = $_POST["price"];
$uploads_dir = "images/";
$tmp_name = $_FILES["image"]["tmp_name"];
$name = $_FILES["image"]["name"];
$tmp_name2 = $_FILES["content"]["tmp_name"];
$name2 = $_FILES["content"]["name"];
move_uploaded_file($tmp_name, "$uploads_dir/$name");
move_uploaded_file($tmp_name2, "$uploads_dir/$name2");
$file_path=$uploads_dir. basename( $_FILES["image"]["name"]);
$file_path2=$uploads_dir. basename( $_FILES["content"]["name"]);
$stmt = $dbh->prepare("INSERT INTO books (title,authors,description,price,image, content)
VALUES ('$title', '$authors', '$description', '$price',$file_path', '$file_path2')") ;
$stmt->execute();
I've looked at similar questions on here but the answers haven't concluded my problem. I have tried the $uploads_dir variable as images/ and as its complete path /project/folder/user/images/ both give the same error.
Note: this php script is in the parent folder of images/.

Answer 1

Your problem is clearly related to permissions. The user under which the php is running doesn't have permissions to write in this images folder. Change the owner of the folder or change the permissions.

Answer 2

It looks like a File Permission error. You can check whether a directory is writable or not by,
$directoryName = "specify your directory name here";
if(is_writable($directoryName){
echo "Directory is writable"; // Returns TRUE if it's writable.
}
else{
}
