    {
        $item = $this->input->post('item');
        $sortname = $this->input->post('sortname');
        $sortorder = $this->input->post('sortorder');

        if (!$sortname) $sortname = 'a.user_id';
        if (!$sortorder) $sortorder = 'DESC';
        
        $page = 1;
        
        $this->db->start_cache();

help anyone. i've been working on a master-detail grid. But to be able to do this i must get the value of $item. If i replace the $item to 1 or 2, records display.

FYI: this is what my firebug gets:
Code:
{
page: 1,
total: 0,
rows: []
}

any pointers/ suggestion will do..

cheers to all.,

try a var_dump on post or echo "---" . $item . "---"; that way if it's null or zero.

#5

tried echoing with this:
Code:
$item = $this->input->post('item');
        var_dump($item);
        echo "—-" . $item . "—-";
....
....
        $this->db->where("sec_companyaccess.user_id", $item);
        var_dump($item);
        echo "—-" . $item . "—-";

and got this error in firebug
Code:
bool(false)
—-—-bool(false)
—-—-<br />
<b>Fatal error</b>:  ob_start() [&lt;a href='ref.outcontrol'&gt;ref.outcontrol&lt;/a&gt;]: Cannot use output buffering in output buffering display handlers in <b>C:\xampp\htdocs\comunion\system\libraries\Exceptions.php</b> on line <b>162</b><br />

thanks again for the help

turn off gzip compression in the config file and re-enable it when you've finished testing everything.

I don't know CI enough on this matter, perhaps this is what the debug option is in the config(figured output was being buffered)?? I'm still thinking in non framework mode.

Basically what it seems is
Code:
$this->input->post('item')
is not being populated. Probably could try
Code:
if (!isset($this->input->post('item')) || $this->input->post('item') === "") { throw new Exception("Nothing here");} else {$item = $this->input->post('item');}

Or set item to 1 as I assume it's an index for a unique record. I have yet to read error handling and debugging so I'm not sure how else to get around this.
