Codeigniter - Passing multiple parameters

Question

I am trying to pass multiple parameters to my model from my controller. It seems that the $scholId that I am trying to pass won't go through to the model after I submit the form. However, the $userId goes through to the database just fine. Is there something wrong with $this->uri->segment(4) that won't pass through correctly?

function apply() 
{
    $this->load->helper('form');
    $this->load->library('form_validation');

    $scholId = $this->uri->segment(4);

    $userId = '2'; //User query -> this will be taken from session

    $this->data['scholarship'] = $this->scholarship_model->getScholarship($scholId);
    $this->data['title'] = "Apply";

    $this->form_validation->set_rules('essay', 'Essay', 'required');

    if ($this->form_validation->run() === FALSE)
    {
        $this->load->view('templates/header', $this->data);
        $this->load->view('student/page_head', $this->data);
        $this->load->view('student/form', $this->data);
        $this->load->view('templates/footer', $this->data);
    }else{
        // Validation passes
        $this->users_model->applySchol($userId,$scholId);
        redirect('/scholarships');
    }
}

can you do var_dump($schoId) before submitting and post it here? — mamdouh alramadan

Make sure you're getting the right segment. Controller is 1, function is 2 etc. Don't count the base url (sort of obvious I suppose) Can you show an example URL that isn't working? Do what mamdouh said dump it out, if it isn't returning what you think or anything try changing it to 3. — Rick Calder

you need to check up the segment whether it exists or not before passing it Like:

if ($this->uri->segment(4) === FALSE)
{
    $schoId = 0; //or anything else so that you know that does not exists
}
else
{
    $schoID= $this->uri->segment(4);
}

or simply:

$product_id = $this->uri->segment(4, 0);
//which will return 0 if it doesn't exists.
