You should be seeing all the File attributes from your var_dump($data) which you created from the $this->upload->data(). So you just need to grab what you want from that. — TimBrownlaw

custom upload filename codeigniter
first you can to explode with (.) in filename, then you get array, then catch the end array with function end().
and last i can to join filename with this date.

$dname = explode(".", $_FILES['gambar']['name']);
$ext = end($dname);
$_FILES['gambar']['name'] = strtolower('fitur_h_'.date('YmdHis').'.'.$ext);

//fitur_h_20200120143157.png  //output filename

i hope my answer can help you

After you uploaded the file, you can get its property by:

$saved_file_name = $this->upload->data('file_name');
// will give you the filename along with the extension

If you want to get the file extension before uploading it, use core php:

$file_ext = pathinfo($_FILES["file"]["name"], PATHINFO_EXTENSION);

or to make it clean

$filename= $_FILES["file"]["name"];
$file_ext = pathinfo($filename,PATHINFO_EXTENSION);

Simply use the below code for image name with extension on post to solve issue,

$config['file_name'].$this->upload->data('file_ext')

I know this is too late, still I'm giving the answer.

If you want to get the image extension, then use pathinfo function with PATHINFO_EXTENSION parameter. eg.

$imageExtention = pathinfo($_FILES["image"]["name"], PATHINFO_EXTENSION);
echo imageExtention;

I was having the same problem and i just figured it out.

I was trying to get the name with this: $this->upload->data('file_name'); but it was always empty, and i just finded out that you need to set something before you can access the data() array.

When your code successfully uploads the file, type this: $data = array('upload_data' => $this->upload->data());

after that, all the data() indexes will be accessible, 'file_name' included. The list with all indexes is in the documentation: https://codeigniter.com/user_guide/libraries/file_uploading.html#preferences

ps: I know it's been 2 years since this post but maybe someone can find it helpful if they stuck with this too.

you can get file name using this code

$file_name = $data['file_name'];
echo $file_name;

and extension for file

$ext = implode('.',$file_name);
echo $ext[1];
