problem with mysqli

[SimonIoa]

I have a problem with mysqli syntax. I really can't see what the problem is in this code. I dont know much about it.
When i use it on a function like this

public function Somefunction()
{

$query=mysqli_query($this->db,"SELECT title,url,img FROM table WHERE status='1' ORDER BY id DESC")or die(mysqli_error($this->db));
while($row=mysqli_fetch_array($query,MYSQLI_ASSOC))
{
$data[]=$row;
}
return $data;
}

its ok when i am trying to use it like i did natively on a page it doesnt work.

<?php 
echo '<label style="font-size:16px">'. $message.'</label><label> at </label>
<a style="font-size:14px">' .$venue.'</a>';?><br><br/>
<?php echo '<label>'. date('l, F d, Y H:i a', strtotime($dategig)).'</label>';
$query=mysqli_query($this->db,"SELECT fan_count FROM messages WHERE msg_id='$msg_id'")or die(mysqli_error($this->db));
$row=mysqli_fetch_array($query,MYSQLI_ASSOC);

$show1='style="display:block;"';
$show2='style="display:block;"';

if ($row['fan_count'] == 0 )
{
    $show1='display:block;';
    $show2='display:none;';
}
else {
    $show1='display:none;';
    $show2='display:block;';
}
?>

what i am missing?

Line 5 uses $this which references the current object instance, which isn't available in your script.

I don't get what you are trying to express. Your first script has no relation to the second one. Can you express yourself vividly?

[tobyITguy]

why dont you consider using procedural instead of object oriented?

that way you have

$link = mysqli_connect('yourHost','username','password','database');

$q = SELECT fan_count FROM messages WHERE msg_id='$msg_id'";

$result = mysqli_query($link,$q) or die('sorry an error ocurred');

$resultRows = mysqli_fetch_assoc($result); 

Then you can access the data like so

echo $resultRows['column']; 

That should work.

Thanks Pritaeas. I should have called it as an function $this->db = $db; I it was a stupid mistake Gideon. The two posts had nothing to do with each other. I just posted them as examples. Pritaeas has shared the solution
