PHP CodeIgniter load view issue, loading full path twice - php

Question

I'm new to PHP CodeIgniter and I'm creating my first app, I've created the controller, model and views to add records to my DB and so far so good,
The problem starts when I click 'submit' in my form,
as instead of redirecting to the same form again if there is an issue in the form or redirecting to the success page, it redirects to the same page but with the full path twice,
like this:
form page - localhost/index.php/news/create
expected results:
form data is valid ->localhost/index.php/news/success
form is invalid -> localhost/index.php/news/create (same page)
but instead it does this when I click submit:
localhost/index.php/news/localhost/index.php/news/create
as you can see, it takes the full path again and puts it afterwards the already existing url.
this is my code
routes.php
$route['news/create'] = 'news/create';
$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';
$route['news/create'] = 'news/create';
main controller
public function view($page = 'home')
{
if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
controller that has the function create of the form
class News extends CI_Controller {
public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Create a news item';
$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('text', 'Text', 'required');
if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('news/create');
$this->load->view('templates/footer');
}
else
{
$this->news_model->set_news();
$this->load->view('news/success');
}
}
}
model:
public function set_news()
{
$this->load->helper('url');
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$data = array(
'title' => $this->input->post('title'),
'slug' => $slug,
'text' => $this->input->post('text')
);
return $this->db->insert('news', $data);
}
Form
<h2><?php echo $title; ?></h2>
<?php echo validation_errors(); ?>
<?php echo form_open('news/create'); ?>
<label for="title">Title</label>
<input type="input" name="title" /><br />
<label for="text">Text</label>
<textarea name="text"></textarea><br />
<input type="submit" name="submit" value="Create news item" />
</form>

Answer 1

Thanks to #tobifasc for the answer,
The problem was in config.php
I replaced
$config['base_url'] = 'localhost';
to this:
$config['base_url'] = 'http://localhost/';
and everything is working properly now

It's happening because you have already view loaded and when your validation failed again you loaded your same view so you don't need to view again. Replace your News controller the create method by this code EX:
class News extends CI_Controller {
public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Create a news item';
$this->form_validation->set_rules('title', 'Title', 'required');
$this->form_validation->set_rules('text', 'Text', 'required');
if ($this->form_validation->run() === FALSE)
{
}
else
{
$this->news_model->set_news();
$this->load->view('news/success');
}
}
}
