Display multiple rows in codeigniter - php

Question

I have query where I fetch the content of about 5 rows each with different content, but i dont now to display them individually in my views.
When I pass the the query->result() from my model back to my controller as $query, and then load a view with the $query data, I don't know how to echo out the e.g. content field of row 1.
I only know how to do this: foreach($query as $row) { echo $row->content; }
But this doesn't allow me to select what row content data (out of the 5 retrieved) I wanna echo out.
Could someone please explain how this is done?

Answer 1

The CodeIgniter documentation includes a section titled Generating Query Results which has some examples of what you are looking for.
Here's an (obviously contrived) example:
model:
class Model extends CI_Model
{
public function get_data()
{
return $this->db->query('...');
}
}
controller:
class Controller extends CI_Controller
{
public function index()
{
$data['query_result'] = $this->model->get_data();
$this->load->view('index', $data);
}
}
view:
<?php foreach ($query_result->result() as $row): ?>
<?php echo $row->field_1; ?>
<?php echo $row->field_2; ?>
<?php // and so on... ?>
<?php endforeach; ?>

function a(){
$this->db->select('*');
$this->db->from('table');
$this->db->where(array('batch_id'=>$batchid,'class_id'=>$classid));
$this->db->where(array('batch_id'=>$batchid,'class_id'=>$classid));
$query=$this->db->get();
for($i=1;$i<=$query->num_rows();++$i){
$data[$i]['task'] = $query->row($i)->task;
$data[$i]['subject_id'] = $query->row($i)->subject_id;
$data[$i]['postdate'] = $query->row($i)->postdate;
$data[$i]['cdate'] = $query->row($i)->cdate;
}
}
