[...]CodeIgniter and Doctrine from scratch. Day 9 – Templates & Data Hydrators | PHP and Stuff[...]…

please tell me where how can find step by step process of codeigniter frame work!

thank you to all

And in “content_view” you have $categories variable. How you can get $categories there if you don’t passed it like this:
$this->load->view($content_view, $vars);

Sorry for my English.

at: system/application/models/forum.php
replace the line-code:
->addSelect(‘p.id, (COUNT(p.id) – 1) as num_replies’)
into this:
->addSelect(‘p.id, COUNT(p.id) – 1 as num_replies’)
note: so, remove the brackets – strange! but that worked for me.

ps: Burak, thanks for the tuts, this is great!!! I am following your tuts from Holland.

I just came across this issue myself, and solved it like this:

// added to the doctrine_tools controller that creates the tables
// from the models, and loads fixtures

function create_sessions_table()
	{

		$this->load->dbforge();

		$fields = array(
            'session_id' => array(
	             'type' => 'VARCHAR',
	             'constraint' => '32',
	      	),
            'user_agent' => array(
	             'type' => 'VARCHAR',
	             'constraint' => '255',
	             'null' => true,
	        ),
            'ip_address' => array(
	             'type' => 'VARCHAR',
	             'constraint' => '20',
	             'null' => true,
	      	),
            'last_activity' => array(
                 'type' => 'INT',
                 'constraint' => '12',
                 'null' => true,
          	),
             'user_data' => array(
                 'type' => 'TEXT',
          	),
        );

		$this->dbforge->add_field($fields);
		$this->dbforge->add_key('session_id', TRUE);
		$this->dbforge->create_table('ci_sessions');
	}

// then just use it in another method from that controller:
$this->create_sessions_table();

hope this helps!

//$thread['num_replies'] = $thread['Posts'][0]['num_replies'];

Because $thread itself has the num_replies element.. Its “Post” element dont have..

Does anyone know why?

A PHP Error was encountered

Severity: Notice

Message: Undefined index: num_replies

Filename: models/forum.php

Line Number: 42

You are correct, afterall

You create the newly structure $thread array and then return the array first obtained by the first DQL query..

Help……
