Hi i have a problem
Fatal error: Call to a member function on a non-object in /3w/zaridi.to/s/spagi/system/application/views/rubrika_detail.php on line 27
Code:
function detail(){
$this->db->where('id_rubriky', $this->uri->segment(3));
$data['query']=$this->db->get('rubriky');
$this->db->where('id_rubrik', $this->uri->segment(3));
$data['diskuze']=$this->db->get('rubdisk');
$this->load->view('rubrika_detail', $data);
$this->db->select('*');
$this->db->from('klienti');
$this->db->join('rubdisk','autor','autor=id_klienta');
$data['ut']=$this->db->get();
$this->load->view('rubrika_detail', $data);
}Code:
<?php
include_once "hlavicka.php";
?>
<div id="welcome" class="post">
<?
if ($query->num_rows() > 0){
$row = $query->row();
?>
<h1 ><?echo $row->seznam;?></h1>
<h2>Citace literatury</h2>
<p> <? echo $row->citace?> </p>
<h2>Postoj autora</h2>
<p><?echo $row->postoj?></p>
<?
}
?>
<h2 align="center">Diskuze:</h2>
<hr>
<? if ($diskuze->num_rows() > 0){
$row = $diskuze->row();
if ($ut->num_rows() > 0){ ////line 27
$ukaz = $ut->row();
?>
<?echo $ukaz->jmeno?>
<p><? echo $row->obsah ?></p>
<?
}
exit;
}
exit;?>
</ul>
<?
include_once "paticka.php";
?>Can anyone explain what is wrong?

I am not exactly sure, but you may want to try in your view rather than having $row = $query->row(), try $row = $query->result(). That's what I use anyway.
If that doesn't work as it is, then I would suggest that you put the results into a foreach statement to loop through all the results:
Code:
foreach($query->result() as $row){
// code in here

I do not know what is wrong, but it still does not work :-S

also, make sure that you have loaded the Database library. I suppose that could be the problem...

why are you loading the same view twice in the same function? also, the error that you are getting points to a problem with your sql query itself, basically it isn't returning anything so when you try to pull something out it errors out.

You are calling the view for the first time before setting $data['ut']. Try removing the view call after the line $data['diskuze']=$this->db->get('rubdisk');
