question regarding default view - El Forum - 11-07-2007
[eluser]Unknown[/eluser]
Hi,
I am writing an application that has urls like:
http://domain.com/profiles/view/3/
This would view the profile with id = 3.
I have this working. Here's a snippet of the controller: (yeah, it's dirt simple)
Code:
function view($id)
{
$this->load->model('Blogmodel');
$data['query'] = $this->Blogmodel->get_by_id($id);
$this->load->view('blogview', $data);
}When I load : http://domain.com/profiles/view/, I get an error, because id is missing.
How do I set the behavior when someone does not include an id?
Thanks.

Code:
function view()
{
if(!$this->uri->segment(3))
{
$this->load->view('someview');
}
else
{
$this->load->model('Blogmodel');
$data['query'] = $this->Blogmodel->get_by_id($this->uri->segment(3));
$this->load->view('blogview', $data);
}

you can also default id to NULL
Code:
function blog_view($id=NULL)
{
if ($id) {
$this->load->model('Blogmodel');
$data['query'] = $this->Blogmodel->get_by_id($id);
$this->load->view('blogview', $data);
} else {
}
}be careful VIEW is a reserved word in php4 I read a post where someone had a problem with naming the functions view as it worked on php5 their locahost but not php4 where there server was hosted.

I've been using something like this:
Code:
function view( $id=FALSE )
{
if (!$id)
show_404();
$this->load->model('Blogmodel');
$data['query'] = $this->Blogmodel->get_by_id($id);
// Assuming get_by_id returns false when that $id isn't found
if (!$data['query'])
show_404();
// whatever else
