Tip: any code with File.DirDefaultExternal is broken code.

Runtime Permissions (Android 6.0+ Permissions)

1. Edit: In B4XPages the permission result event signature is: Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean) 2. Important to read: https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/#content If the targetSdkVersion is...

I confirm that I request permission and I can READ and WRITE Correctly from External Disk Space.
AddPermission("android.permission.WRITE_EXTERNAL_STORAGE")
AddPermission("android.permission.READ_EXTERNAL_STORAGE")
Before to Call upload function I check if file exist, and there is.

About PHP is simple:

PHP:

//....

    foreach($_FILES as $fname => $fvalue) {
        echo date("d.m.Y H:i:s", time()).": ".$fname."=".$fvalue."\r\n";
        foreach($fvalue as $name => $value) {
            echo date("d.m.Y H:i:s", time()).": ".$name."=".$value."\r\n";
        }
    }
        
    // CHECK IF UPLOAD COMPLETE   
    if (!isset($_FILES['file']) || !is_uploaded_file($_FILES['file']['tmp_name']))
    {
        echo "<script>alert('ERROR: FILE NOT ATTACHED');</script>";       
        exit;   
    }

The PHP script works correctly with a HTML POST Page, but with B4A the $_FILE is Empty.

Use https://ptsv2.com/ to see what your B4A app actually uploads via the POST (be it PostMultiPart or PostFile).

Thank you much !
using https://ptsv2.com/ i generate a new TOLIET, insert the link to my B4A application and I received the file with my photo.
Using j.PostMultipart works, using j.PostFile not works.

Therefore the problem is server side, but SOMEBODY CAN help me to understand WHERE IS the problem ?
Inside Server PHP I already have:
file_uploads = On;
post_max_size = 8M;
upload_max_filesize = 8M;

What is the output of these lines when using PostMultiPart from B4A?

the foreach exit because $_FILES count = 0

it seems that when the server receives the request it immediately rejects it and deletes the request parameters, in fact the connection takes place very quickly instead using the suggested site the file is transferred on 4-5sec.
it's surely a server problem but I do not understand what.
