You cannot rely on undefined variables in PHP. You must test to see if they exist and contain useful values before you use them in a script.

In case you're new to PHP and want to get a foundation (necessary for working on PHP internals of CodeIgniter or any other framework) this article might help.

I think you get that error when you load the page before to submit your query: this means that the chek
if($this->input->post('sub
fails and then the variable $dt['val'] is never filled and when the view is loaded it raises the error. Put a check in the View:
And the error will go away :-)

<?php echo $va['namehost'];?><br>

About your model, here you'll find the info you need:https://ellislab.com/codeigniter/user-guide/database/active_record.html
public function mgetclinds($a,$b,$c,$d,$e,$f,$g,$h,$i,$j)
{
$array = array(
'state' => $f,
'city' => $g,
'area' => $h,
'cate' => $i,
'for' => $j
);
$this->db->like($array);
$query=$this->db->get($a,$b,$c,$d,$e);
return $query->result_array();
}?>

Ok, I'd have to look at your code with more attention. It is inconsistent. Look at this: your model method accept 10 parameters
Let's summarize: you want look for records which have area, city, state etc LIKE the ones submitted by the user, right? Okay rewrite code this way and see if it makes sense:
Controller:
Model:
public function mgetclinds($a,$b,$c,$d,$e,$f,$g,$h,$i,$j)
$dt['val']=$this->demomod->mgetclinds('reg',$selected1,$selected2,$selected3,$selected4,$selected5);
Let's summarize: you want look for records which have area, city, state etc LIKE the ones submitted by the user, right? Okay rewrite code this way and see if it makes sense:
Controller:
<?php //ON CONTROLLER//
public function extra1()
{
if($this->input->post('submit'))
{
$selected1=$this->input->post('state');
$selected2=$this->input->post('city');
$selected3=$this->input->post('area');
$selected4=$this->input->post('cate');
$selected5=$this->input->post('for');
$dt['val']=$this->demomod->mgetclinds($selected1,$selected2,$selected3,$selected4,$selected5);
}
$this->load->view('extra1',$dt);
}
?>
Model:
public function mgetclinds($state,$city,$area,$cate,$for)
{
$array = array(
'state' => $state,
'city' => $city,
'area' => $area,
'cate' => $cate,
'for' => $for
);
$this->db->like($array);
$query=$this->db->get('city', 'state', 'area', 'cate', 'for');
return $query->result_array();
}?>

I strongly discourage you from hiding errors, warnings and even notices: if there is an issue, then solve it now. Hiding it just grant you to accumulate an incredible amount of small issues which, all together, can make your life a nightmare.
That error is probably because the creation of $dt variable depends on the submission of values. If the user doesn't submit anything, that is if you access the page directly typing in the adddress bar of your browser www.yourdomain.com/controller_name/extra1, then the $dt array doesn't exsist, but you pass it to the view anyway: from here the warning. Do this instead:
