mime-type problem-solving tricks.

[eluser]Unknown[/eluser]
I had problems when uploading files. with the error: "The filetype you are attempting to upload is not allowed.".

after I learned the cause. I changed the code Function is_allowed_filetype on upload.php file (library).

before :

Code:

function is_allowed_filetype()
    {
        if (count($this->allowed_types) == 0 OR ! is_array($this->allowed_types))
        {
            $this->set_error('upload_no_file_types');
            return FALSE;
        }

        $image_types = array('gif', 'jpg', 'jpeg', 'png', 'jpe');

        foreach ($this->allowed_types as $val)
        {
            $mime = $this->mimes_types(strtolower($val));

            // Images get some additional checks
            if (in_array($val, $image_types))
            {
                if (getimagesize($this->file_temp) === FALSE)
                {
                    return FALSE;
                }
            }

            if (is_array($mime))
            {
                if (in_array($this->file_type, $mime, TRUE))
                {
                    return TRUE;
                }
            }
            else
            {
                if ($mime == $this->file_type)
                {
                    return TRUE;
                }    
            }        
        }
        
        return FALSE;
    }

changed :

Code:

function is_allowed_filetype()
    {
        if (count($this->allowed_types) == 0 OR ! is_array($this->allowed_types))
        {
            $this->set_error('upload_no_file_types');
            return FALSE;
        }

        $image_types = array('gif', 'jpg', 'jpeg', 'png', 'jpe');

        foreach ($this->allowed_types as $val)
        {
            $mime = $this->mimes_types(strtolower($val));

            if (is_array($mime))
            {
                if (in_array($this->file_type, $mime, TRUE))
                {
                    // Images get some additional checks
                    if (in_array($this->file_type, $image_types))
                    {
                        if (getimagesize($this->file_temp) === FALSE)
                        {
                            return FALSE;
                        }
                    }

                    return TRUE;
                }
            }
            else
            {
                if ($mime == $this->file_type)
                {
                    // Images get some additional checks
                    if (in_array($this->file_type, $image_types))
                    {
                        if (getimagesize($this->file_temp) === FALSE)
                        {
                            return FALSE;
                        }
                    }

                    return TRUE;
                }    
            }        
        }
        
        return FALSE;
    }

probably not good writing structure. but my problem solved with that.

good luck.
