Edit post with CodeIgniter

Jmz · 11-11-2009, 10:25 PM

I'm playing with CodeIgniter for the first time and I've managed to confuse myself. I've made a very simple blog script which I can add posts with, now I want to make an edit post page.

My controller looks like:

PHP Code:


			
    function edit_posts()

    {

        $this->load->helper('form');

        $this->load->model('posts_table');

        $data['posts'] = $this->posts_table->edit_post();

        $this->load->view('edit_posts', $data);

    }

And the model:

PHP Code:


			
    function edit_post() 

    {

        $this->db->where('id', $this->uri->segment(3));

        $query = $this->db->get('posts');

    }

How do I display the stuff it gets from the database in my view? All the examples I can find use loops but I'm only displaying one result so I don't need a loop do I?

I'm not very familiar with Code Igniter, but if it's just one result I wouldn't think you would need a loop. Atleast, I have never seen a loop used to print just one single result. I am not too familiar with CI's database abstraction, but check out the manual and see about pulling just one row set. If anything you might have to loop through an array of one rows data, but that depends on how CI returns its row set.

If you're practicing by writing a blog script, there's no reason not to use a loop either. Always design with the other side of the tunnel in sight - who would want a blog that only ever displayed a single post? Loops can be used to display a single item, or multiple items, the beauty of them is that they don't need to know beforehand, they'll just do their job.

As for a useful answer to your question, I have none. Never used CodeIgniter. The name freaks me out, cause the last thing I need is for my computer to spontaneously combust.

The second argument of $this->load->view(); takes the array with values. The arraykeys (names) of easy value in the array is transformed into a variable in the view itself. (extract() function)

So when I call the view like this from my controller:

$this->load->view('test', array('test' => 'hello world'));

I can read it like this in my view:

My testvalue: <?=$test?>

Another thing would be for you to name your methods a bit different. Both of the mentioned methods should simply be named edit(), seeing as the class name says - or should at least - either Post (model) or Posts (controller) (or something similar to that).
