Hi there

My app is deployed on

and this is where my php file is.

I need to create a folder in the drive on this path using php from my app.

What should be the path to pass to my folder creation. For example, if I pass "./assets/Anele", the folder will be created inside the riuso folder.

Thanks in advance for your help.

If you have access to the destination folder you could use absolute and relative paths.
PHP:
echo realpath($_SERVER['DOCUMENT_ROOT']) . "<br>";
echo realpath($_SERVER['DOCUMENT_ROOT'] . '/../../../_temp/dbconnection.php');
And this is the result:

In this example the file dbconnection.php is located in the _temp folder of the E-drive.
The ../ goes up one level of the folder tree.
If you reach the root folder then you can go down the folder tree to the destination folder (in my case it was E:\_temp
Happy coding!

In simple terms this is my process flow and what I need to achieve.

1. Upload an image to assets folder in the app space. This is deployed in /var/www/html/riuso

This upload script is a file named upload.php inside the assets folder. This works well.

B4X:
<?php
header("Access-Control-Allow-Origin: *");
set_time_limit(0);
if (isset($_FILES['upload'])) {
    // Example:
    if(move_uploaded_file($_FILES['upload']['tmp_name'], "../assets/" . $_FILES['upload']['name'])){
        echo '{ "status": "success" }';
    } else {
        echo '{ "status": "error" }';
    }
    exit;
} else {
    echo '{ "status": "error" }';
}
?>

2. Now in the drive of the server in the folder named /root/Files, this is outside the app space. I need to create a sub folder and then move the image file there, renaming the image file to be img.png. The code to create folders is in the ruiso.php file above. This is the part I dont know how to achieve.

In the php file above, I have this code to create a folder

B4X:
function DirectoryMake($dirpath) {
    $target_exists = is_dir($dirpath);
    if ($target_exists) {
    die("yes");
    }
    mkdir($dirpath, 0700, true);
    //return directory existence
    $res = DirectoryExists($dirpath);
    die($res);
    }

B4X:
function DirectoryExists($path) {
    $target_exists = is_dir($path);
    if (!$target_exists) {
    //source does not exist
    die("no");
    }
    die("yes");
    }

I have done a call like

DirectoryMake("/root/Files/Image1"), I am assuming this will assume a process from where the php file resides, it does not work.

Please help.

    }
I have tested the 2 functions they work fine . what is php deployed on or you run php directly? perhaps some permissions are not allowed?
