Codeigniter 4: Uploading files with move_uploaded_file

问题

I just started moving CodeIgniter 3 project to CodeIgniter 4.

Everything works fine except file upload.

I would like to keep the user uploaded files in /writable/uploads. Below is the code I use to move the uploaded file to desired location.

            $target_dir = '/writable/uploads/recordings/';
            $target_file = $target_dir . basename($_FILES["gfile"]["name"]);
            $FileType = pathinfo($target_file,PATHINFO_EXTENSION);

            if($FileType != "mp3") {            
             $vmuploadOk = 1;
            }               
            else
             $vmuploadOk = 1;   


            if ($vmuploadOk == 1) {
                $greetfile = $id . "g" . basename($_FILES["gfile"]["name"]);

                $target_filenew = $target_dir . $greetfile;     

                move_uploaded_file($_FILES["gfile"]["tmp_name"], $target_filenew);                 
            }

I assume that it is because CI4 keeps writable folder outside public folder.

This worked for me and I hope it will also work for you. In codeigniter 4 please use this to upload your files and move it in your controller.


if($imagefile = $this->request->getFiles())
{
    if($img = $imagefile['gfile'])
    {
        if ($img->isValid() && ! $img->hasMoved())
        {
            $newName = $img->getRandomName(); //This is if you want to change the file name to encrypted name
            $img->move(WRITEPATH.'uploads', $newName);

            // You can continue here to write a code to save the name to database
            // db_connect() or model format

        }
    }
}


        if($img = $this->request->getFile('gfile'))
        {
            if ($img->isValid() && ! $img->hasMoved())
            {
                $newName = $img->getRandomName();
                $img->move('./public/uploads/images/users', $newName);

                // You can continue here to write a code to save the name to database
                // db_connect() or model format

            }
        }

Then in your html Use this

<input type="file" name="gfile">

I hope this will help you else call my attention.

You are not using CodeIgniter's built in functions. Everything shown in your code are PHP functions. If you want to leverage built in CI functions, then look through the documentation as linked by @Boominathan Elango.

To get the file from the request:

$file = $this->request->getFile('here_goes_input_name');

As specified here

To move the file using CI function:

$file->move(WRITEPATH.'uploads', $newName);

As specified here
