CodeIgniter Upload Class Allowed File Types - php

Question

I'm using Codeigniter Upload Class but I have a problem with allowed file types. I need to allow only pdf files to upload but any kind of file can be upload. Here is my code;
model (muser.php);
function cv_ekle()
{
$config['upload_path'] = 'uploads/cv';
$config['allowed_types'] = 'pdf';
$config['max_size'] = '0';
$config['max_width'] = '0';
$config['max_height'] = '0';
$this->load->library('upload', $config);
$this->upload->do_upload();
$data = $this->upload->data();
$this->load->library('upload', $config);
$upload_data = $this->upload->data(); //Returns array of containing all of the data related to the file you uploaded.
$file_name = $upload_data['file_name'];
$data = array
(
'userid' => $this->session->userdata('id'),
'kullanici' => $this->session->userdata('isim'),
'kategori' => $this->input->post('kategori'),
'tarih' => time(),
'dosya' => $file_name
);
if($this->db->insert('cv', $data))
{
return true;
}
else
{
return false;
}
}
controller (cv.php);
function cv_ekle()
{
if($this->muser->cv_ekle())
{
$this->session->set_flashdata('ok', 'CV başarıyla gönderildi!');
redirect('cv');
}
else
{
$this->session->set_flashdata('hata', 'Sadece PDF, Excel ya da Word formatında yükleme yapabilirsiniz!');
redirect('cv');
}
}
view (cv.php);
<form method="post" action="<?php echo site_url('cv/cv_ekle'); ?>" class="login" enctype="multipart/form-data">
<div class="controls">
<label for="email">Dosya: <span class="text-error">*</span></label>
<input type="file" id="pass" class="input-block-level" name="userfile" >
</div>
<div class="controls">
<label for="email">Kategori: <span class="text-error">*</span></label>
<select class="input-block-level" name="kategori">
<?php foreach($kategoriler as $kat) { ?>
<option value="<?php echo $kat['isim']; ?>"><?php echo $kat['isim']; ?></option>
<?php } ?>
</select>
</div>
<div class="controls">
<button type="submit" class="btn btn-primary">CV Yükle</button>
</div>
</form>
Thanks in advance!
