CodeIgniter - Returning uploaded file data

Question

Im using codeigniters file upload library .... everything works fine except i want to output the uploaded file details.

I have the following code

$uploaddata = $this->upload->data('userfile');
foreach($uploaddata as $details){
    echo $details['file_name'];
}

The above code keeps erroring with the following

Message: Undefined index: file_name

Could someone let me know where im going wrong,

Cheers

Could you provide more code. The form validation, the full callback, etc. — NexusRex

I don't know the problem, but I think it will help you if you first know "what is the content of $uploaddata" by writing: var_dump($uploaddata) just before foreach loop...

The results from the var_dump are very confusing .... it echoed the following ... array(13) { ["file_name"]=> array(1) { [0]=> string(21) "Air-Max-1-Premium.jpg" } ["file_size"]=> array(1) { [0]=> float(63.78) } ["file_type"]=> array(1) { [0]=> string(10) "image/jpeg" }

I sent one comment, but it was wrong and I deleted it... I looked at my codes: $upload_data = $this->upload->data(); $file_name = $upload_data['file_name']; $file_path = $upload_data['full_path']; I think you can not use foreach in that way, because in every cycle it will return it's content...

When i echo out $file_name, it just returns 'Array'

try this one: foreach($uploaddata as $detailkey => $detail){ if (is_array($detail)){ echo $detailkey ." = ". $detail[0] ."<br>"; } elseif(!is_null($detail)) { echo $detailkey ." = ". $detail ."<br>"; } }

That works perfect if there is only one file ... what happens if there are multiple file fields with names like userfile[] ... it only echos out the information for the first file uploaded ... weird
