Model help noob

[eluser]dmisterct[/eluser]
I just started developing with models and I need help with the insert portion, I have a Model something along

Code:

<?php
class Mymodel extends CI_Model {
  var field1;
  var field2;
  var field3;
  
  function __construct() {
     parent::__construct();
  }

  function insert_entry($field1, $field3) {
    $this->field1 = $field1;
    $this->field2 = $this->input->post('field2');
    $this->field3 = $field3;
    $this->db->insert('table', $this);   // This line does not work, it does not execute this statement
  }
}
?>

and a Controller like:

Code:

<?php
class MyController extends CI_Controller {
  public function method() {
     $var1 = "hello";
     $var2 = "world";
     $this->load->model('mymodel', 'model', TRUE);
     $this->mymodel->insert_entry($var1, $var2);
  }
}
?>

I used error_logging and I found that the

Code:

$this->db->insert('table', $this);

in Mymodel does not execute and I can't figure out why. I've read CodeIgniter's Models tutorial and this seems like it should work. (http://ellislab.com/codeigniter/user-gui...odels.html) I was wondering if someone could point out what I did wrong.

not test but try this,

Code:

<?php
class Mymodel extends CI_Model {
public $data = array(
                   'field1' => '',
                   'field1' => '',
                   'field1' => ''
    );

  function __construct() {
     parent::__construct();
  }

  function insert_entry($field1, $field3) {
    $this->data['field1'] = $field1;
    $this->data['field2'] = $this->input->post('field2');
    $this->data['field3'] = $field3;

    $this->db->insert('table', $this->data);
  }
}
?>


<?php
class MyController extends CI_Controller {
  public function method() {
     $var1 = "hello";
     $var2 = "world";
     $this->load->model('mymodel', 'model', TRUE);
     $this->mymodel->insert_entry($var1, $var2);
  }
}
?>

That didn't seem to fix my problem.

If it helps here is the software stack on my OS

PHP 5.3.3
CentOS not sure which version.

Insert expects and associate array or a class object!

Code:

public function insert_entry($field1, $field3)
{
    $data = array(
        'field1' => $field1,
        'field2' => $this->input->post('field2'),
        'field3' => $field3
    );

    $this->db->insert('table', $data);
}

I'm just wondering, this database and the tables already existed. I'm actually trying to take an existing application and convert it into a CodeIgniter based application. Does having an existing database with certain existing fields prevent CodeIgniter's data models to combine?

So for example from a mysql vardump I get the previously created table which I am trying to model:

Code:

CREATE TABLE `table` {
    `field1` INT(18) NOT NULL AUTO_INCREMENT,
    `field2` INT(18) NOT NULL,
    `fielrd3` VARCHAR(50) DEFAULT NULL
}

Also @ InsiteFX, I thought that

Code:

$this

meant this class. Is that not a class object of the current class? If not then the tutorial on CodeIgniter's Model page is misleading.

I did try using an associate array and it does not work. I can only assume my problem has to deal with the database itself. I am hoping if anyone could give some insight as to whether or not adding to an existing database with an existing schema affects how I should insert using CodeIgniter's data models.

Ok I figured out what was wrong, I misspelled one of the field names. It was such a small typo.
