codeigniter upload images from different inputs - codeigniter

Question

my code is working fine in the single upload, but I want to make a loop for my code that I won't repeatedly create a function over and over because of using two different inputs.
public function uploadImage_1()
{
$config['upload_path'] = './uploads';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '2608';
$config['max_width'] = '2608';
$config['max_height'] = '2608';
$this->load->library('upload', $config);
if ( !$this->upload->do_upload('userfile1')){
$error = array('error' => $this->upload->display_errors());
}else{
$fileName = $this->upload->data();
$post_image = $fileName['file_name'];
return $post_image;
}
}
public function uploadImage_2()
{}
` View
<input type="file" name="userfile1" size="20" required/>
<input type="file" name="userfile2" size="20" required/>`

You can pass the input field name as parameter into your function.
like this:
public function uploadImage($input_field_name)
{
$config['upload_path'] = './uploads';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '2608';
$config['max_width'] = '2608';
$config['max_height'] = '2608';
$this->load->library('upload', $config);
if ( !$this->upload->do_upload($input_field_name)){
$error = array('error' => $this->upload->display_errors());
}else{
$fileName = $this->upload->data();
$post_image = $fileName['file_name'];
return $post_image;
}
}
Now use the above function like this:
// These variables stores the name of your files
$fileName_1 = $this->uploadImage('userfile1');
$fileName_2 = $this->uploadImage('userfile2');
