There is a form that has 4 text fields, Name, Mobile, Email & Image. However Image field is optional. When I submit the data without inserting an image it shows "You did not select a file to upload". How to solve it.

My controller function is:

public function addAgent()
$this->form_validation->set_rules('AgentName','AgentName','required');
$this->form_validation->set_rules('mobile','mobile','required');
$this->form_validation->set_rules('email', 'email', 'required');
if ($this->form_validation->run() == FALSE) 
$this->session->set_flashdata('registerMessage',errors(),':old:');
redirect(base_url());
else
$config['upload_path'] = './uploads';
$config['allowed_types'] = 'gif
$data = array(
'AgentName' => $this->input->post('AgentName'),
'mobile' => $this->input->post('mobile'),
'image' => $filename,
'email' => $this->input->post('email')
);
$this->general_model->insert('agent',$data);
$this->session->set_flashdata('registerMessage','AddedSuccessfully',':old:');
redirect(base_url());

Check if the file array for that key image is populated and if it has a tmp_name:

public function addAgent() 
 $this->form_validation->set_rules('AgentName', 'AgentName', 'required');
 $this->form_validation->set_rules('mobile', 'mobile', 'required');
 $this->form_validation->set_rules('email', 'email', 'required');
 if ($this->form_validation->run() == FALSE) 
 $this->session->set_flashdata('registerMessage', errors(), ':old:');
 redirect(base_url());
 
 $filename = ''; // init as blank otherwise notice
 if (isset($_FILES['image']) && !empty($_FILES['image']['tmp_name'])) 
 $config['upload_path'] = './uploads/'; // should have slash at end
 $config['allowed_types'] = 'gif
 $data = array(
 'AgentName' => $this->input->post('AgentName'),
 'mobile' => $this->input->post('mobile'),
 'image' => $filename,
 'email' => $this->input->post('email')
 );
 $this->general_model->insert('agent', $data);
 $this->session->set_flashdata('registerMessage', 'AddedSuccessfully', ':old:');
 redirect(base_url());
