Are you looking for codeigniter get extension of file before upload then i will help you to get file extension in codeigniter from file name. we can get file extension using pathinfo() php function.

I was new to codeigniter application. i was using codeigniter 3 version. i was doing image upload task on my project and i need to make custom name of image when you upload on my server. At that time need to get image file extension from name and then i will rename it form extension. i search a lot about to getting directly for file extension but it was not there in codeigniter docs. i thought and find way to do it using php pathinfo().

I created simple example for getting file extension in codeigniter project. so you can see both example, i hope it can help you.

Example 1:

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


Example 2:

$fileName = $this->upload->data('image');

$fileExt = pathinfo($fileName, PATHINFO_EXTENSION);


I hope it can help you...
