I'm using flutter to upload files to a Php codeigniter 4 server. My problem is when I add validation for the uploaded file type. It always return file does not have a valid file extension.

Upload.php

$rules = [
 'file' => 'uploaded[file]|max_size[file, 4096]|ext_in[file,jpg,jpeg,png,doc,docx,pdf]'
];

Here is the debug of $_FILES that I recieved.

{"file":{"name":"file_test.jpg","type":"application\/octet-stream","tmp_name":"C:\\xampp\\tmp\\php623C.tmp","error":0,"size":169233}}

  • Have you tried to add ".tmp" extension in your ext_in? Because your file is not actually a .jpg when importing it through $_FILES variable but a .tmp. – ViLar Nov 27 '20 at 07:28
