JInput->files unreliable in Joomla 4

[Kenneth Genesis]

Howdy. I'm modernizing a corporate app from Joomla 3 to Joomla 4. The various user upload forms started failing randomly on some files leaving no error log. It was as if the file was never included in the upload.

BUT I found it in $_FILES. So PHP saw the file but Joomla did not.

After much hair-pulling, I found a comment that says Joomla may be filtering the results.

If this is true, I've hunted for a way to disable this filter.

For now, I've done a search and replace to remove $input->files and reach past Joomla to get $_FILES. I'm hoping this is temporary, but I can't roll this app out if it only works some times.

So ya, if anyone can point me to a way to just "get all files from input" I'm sure there's a simple parameter I couldn't find

I have the same issue, where this does not work

$files = $this->input->files->get('data', [], 'array');

And this is where the form data is

 $app->input->get('jform')

So where is the actual file data? as $_FILES has it?

I have this in the the template

<input required type="file" class='form-select' id="import-file" name="Filedata[]" multiple />

and then this in the controller

$files = $this->input->files->get('Filedata', [], 'array');

Allows me to multi-select a list of files and access their data.  All of them.  Always.

Ok,

So not using the /forms/formname.xml which I did?

So why is there a "file" type in the form documented at Joomla, if no-one are able to use it?

I'm sure you can use the xml type.  That should generate the same html as I used above.  The you just need to make sure the rest of the naming lines up.

Thanks,

But I can't get it to work using the forms, only when I am not using the form.

Are there any real example where someone has made it work by using the form to actually upload a file?
