Database results will not display. New to CI - El Forum - 04-25-2009
[eluser]cpeele[/eluser]
Hey guys, I am very new to codeIgniter and am trying to get my page to display some database results but no rows show.
1) I have data in my database
2) I have set autoloading
3) Here is my database configuration:
Code:
$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "qno";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";4) Here is my Controller
Code:
<?php
class Questions extends Controller
{
function index()
{
$data['query'] = $this->db->get('questions');
$this->load->view('questions', $data);
}
}
?>5) Here is my view
Code:
<?php if($query->num_row() > 0): ?>
this does not show :(
<?php endif; ?>
<ul>
<?php foreach($query as $row): ?>
<li><?=$row->name?></li>
<?php endforeach; ?>
</ul>6) Here is my output when I do a print_r($data);
Code:
Array ( [query] => CI_DB_mysql_result Object ( [conn_id] => Resource id #28 [result_id] => Resource id #29 [result_array] => Array ( ) [result_object] => Array ( ) [current_row] => 0 [num_rows] => 2 [row_data] => ) )Please if anyone can help me I would really appreciate it. I would like to start using CI over CakePHP but I can't even get this to dispaly database results.
Thanks for any help,
Chris

Code:
$query = $this->db->get('questions');
$data['query'] = $query->result_array();That will convert yout mysql resource into the array you need.

But he's using the query object in the view (num_rows)
And he's using it as an object, not an array
Changing the foreach loop to be
Code:
<?php foreach($query->result() as $row): ?>Database results will not display. New to CI - El Forum - 04-25-2009

My bad, didn't see the view part
just use
Code:
$data['query'] = $query->result()That will pull an object data from the resource so you don't have to change the view file.

He will still have to change the view, as he calls num_rows, which is called on the query object
So he either converts the query to a result after that, or uses sizeof on the results

Hey guys, thanks for all the responses.
I tried all your suggestions to no avail unfortunately
Code:
<?php
class Questions extends Controller
{
function index()
{
$query = $this->db->get('questions');
$data['query'] = $query->result();
}
}
?>I even tried using
Code:
$data['query'] = $query->result_array();here's the view
Code:
<ul>
<?php foreach($query->result() as $row): ?>
<li><?=$row->name?></li>
<?php endforeach; ?>
</ul>it shouldn't be this hard to pull some data...any additional ideas would be greatly appreciated.

you now alppear to be calling ->result() on the query in the controller, and you try calling it on what is now the result (although called query in the view
try
Code:
<?php
class Questions extends Controller
{
function index()
{
$query = $this->db->get('questions');
$data['questions'] = $query->result();
}
}
?>
// view
<ul>
<?php foreach($questions as $question): ?>
<li><?=$question->name?></li>
<?php endforeach; ?>
</ul>Database results will not display. New to CI - El Forum - 04-26-2009

Does that give you an error, or just doesn't have the results you expect?
