Question

$config['file_name'] allows us to set the filename, while uploading files in CodeIgniter. Here we need to write the filename with the file extension. For example, filename.pdf or filename.zip. I want to set the filename, but the extension. So, if someone uploads a pdf file, the filename will be myfilename.pdf. And if someone uploads a zip file, the filename will be myfilename.zip.

Answer 1

start off the upload stuff in your controller like this and you can name it whatever you want. just replace ‘new_file_name’ with whatever you want it to be called. Make sure you change the do_upload() function variable to the name of your file input as well.

if ($this->upload->do_upload('your_filename')) {
            $img_data=$this->upload->data();
            $new_imgname='new_file_name'.$img_data['file_ext'];
            $new_imgpath=$img_data['file_path'].$new_imgname;
            rename($img_data['full_path'], $new_imgpath);
