You are trying to save a file outside of your hosting space.

Show your code so we can see where you are trying to save the file to?

Thank you, @m7vm7v , I went through those link however still have same problem.

Yes, I am trying to save a file outside of my hosting space.

It was working fine, even I have uploaded multiple files before. However, recently some changes has been made by security team on server and from that time I have an error.

And here is my code

$data = [

        'title'=>$request->title,
        'category_id'=>$request->category_id,
        'slug'=>str_slug($request->title),
        'start_time'=>Carbon::parse(strtotime($request->start_time))->format('Y-m-d'),

    ];

    if (request('file')) {
        $file = request('file');
        $file_name = time() . $file->getClientOriginalName();
        $file->move('uploads/Letter', $file_name);
        $data['file'] = 'uploads/Letter/'.$file_name;
    }

Thank you @snapey .

You may have to put images under public_HTML if that is the case. Are you allowed to store images at least one folder above public_HTML. Also what host are you using.

You may want to start a ticket and find out exactly what is and what is not allowed.

Or even consider moving to something like digitalocean. Just a thought.

@jlrdw thank you, it's simple hosting or can say private by organization. and what means of images under public_HTML.

Meaning whatever your public folder is. Give me a minute I'm on tablet I will post another link for you to look at I have to boot up my desktop.

See https://laracasts.com/discuss/channels/laravel/next-issue-fonts-and-images-arent-visible

I don't know your folder structure but in this image main larave is above public_html and public is now inside public_html called laravel54. (public can be renamed, I did).

Also public_html on some host have other names, like www, htdocs, etc.

You may want to show your folder structure for us to help.

Just create an account on imgur.com, upload screenshot, and view image, and place here in an image tag:

Like

<img src="https://i.imgur.com/Oo6k4Fp.jpg" />

Edit: Have you tried to move (store) image under your storage folder.

I will ask to server manager to send the screenshot of server file images so it will help me more. And I will update here.

Thank you @jlrdw

@jlrdw here is link of image

I tried to change the path , it was outside of App_files then I make inside App_files.

Thats some complex setup.

I hope your .env file is not available to download.

Anyway, as tmp is also used to hold the actual upload before you move it, comment out your code that actually saves the file and make sure you can upload without errors (not actually moving the file)

Yes @snapey , thank you.

In .env file is not available to download.

Yes file are not moving.

so where I have to make changes in controler?

Yes file are not moving.

Sorry I don't know what you mean. Do you get an error if you don't try to save the file?

show us config/filesystems.php

Please format your code by putting 3 backticks ``` on a line before and after each code block

No if I am editing the text then there are no error and sorry , my means file are not moving means , not saving on data base.

Thanks @snapey

I don't think you understood what I was asking.

I'll try again.

Do this to your code;

    if (request('file')) {
//        $file = request('file');
//        $file_name = time() . $file->getClientOriginalName();
//        $file->move('uploads/Letter', $file_name);
//        $data['file'] = 'uploads/Letter/'.$file_name;
    }

NOW upload a file. Do you still get the error?

@snapey , I changed the code and still has same error.

here is link of config/filesystems.php

Thank you

@me10071990 somewhere run this

echo sys_get_temp_dir();
die;

EDIT: also check

echo ini_get('upload_tmp_dir');  // probably this one
die;

It will give you the tmp folder.

Then make sure that tmp folder has correct permissions:

chmod -R 777 /your/tmp/folder

And also make sure the folder you move to has correct permissions. But I don't think that's the problem.

But you said it worked until some security changes took place, ask someone,

What they did.

so the problem is with your hosting setup, not your application.

Your web server account cannot read/write php's tmp folder

@m7vm7v @snapey @jlrdw, thank you all, it works , the security check has been updated, so from outside I was not able to upload. Now working.

Thank you so much all.

Good to see you got it working.
