Why would $_FILES be empty when uploading files to PHP? (20 answers)

Closed 3 years ago.

i have this input type

  <input class="btn btn-success" type="file" name="profile_image" style="margin-top:10px; margin-left:20px;"></input>

user will add the image file from here, and the PHP code to upload the file

if(isset($_FILES['profile_image']))
            {
                $image_type = $this->getImageType($_FILES['profile_image']);

                if($image_type == 'image')
                {
                    $extension = pathinfo($_FILES['profile_image']['name'], PATHINFO_EXTENSION);
                    $filename = '123_'.uniqid().'.'.$extension;
                    move_uploaded_file($_FILES['profile_image']['tmp_name'], '../functions/images/images/'.$filename);
                }
            }
else
            {
                $filename = 'default_profile_image.jpg';
            }

and the getImageType

public function getImageType($file)
    {
        $imageMime = getimagesize($file['tmp_name']);
        $type = explode('/', $imageMime['mime']);
        return $type[0];
    }

but it does not read $_FILES['profile_image'] and rather moves to else part. why does it not read $_FILES ? is there anything missing?

add this code in form tag
enctype="multipart/form-data"

<form action="upload.php" method="post" enctype="multipart/form-data">
