RE: blog form - PaulD - 04-25-2016
Like Cartalot said, this usually happens when you do not load the form helper in the controller.
PHP Code:
$this->load->helper('form');
Best wishes,
Paul
RE: blog form - davy_yg - 04-26-2016
I already load the helper.
controllers/blog.php
PHP Code:
<?php
class Blog extends CI_Controller {
public function index()
{
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->model('blog_model');
$data['title'] = $this->blog_model->select_blog();
$data['content'] = $this->blog_model->select_blog();
$data['date'] = $this->blog_model->select_blog();
$this->load->view('blog', $data);
//$this->load->view('blog');
}
public function blog_form()
{
$this->load->view('blog_form');
}
}
?>RE: blog form - mwhitney - 04-27-2016
The index() method does not run when you are routed to the blog_form() method. If you want code to run for every method in a controller, you need to create a constructor:
PHP Code:
class Blog extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
$this->load->model('blog_model');
}
public function index()
{
$data['title'] = $this->blog_model->select_blog();
$data['content'] = $this->blog_model->select_blog();
$data['date'] = $this->blog_model->select_blog();
$this->load->view('blog', $data);
}
public function blog_form()
{
$this->load->view('blog_form');
}
}
