Function error? Help to echo?

Hi,

i em trying to build in a comment system on my site on my tutorials. Here is the code for it..

$category = $_GET['t'];
$step = $_GET['s'];

$spp = $sys->R('System.StepsPerPage');


$get_cdata = $db->query("SELECT * FROM tutorials WHERE t_url = '".$category."'");
if($db->numrows($get_cdata) != 0){

	$mtutorial = $db->fetch();

	$loadsteps = array();

	if($spp == 1){
		$loadsteps = array($step);
	} else {
		for($i=(($step-1)*$spp)+1;$i<=($step*$spp);$i++){
			$loadsteps[] = $i;
		}
	}

	$db->rs_create("SELECT * FROM steps WHERE s_for_tutorial = '".$mtutorial['t_id']."' AND s_number IN (".implode(',', $loadsteps).")");
	$msteps = $db->rs_flush();

} else {
	$mtutorial = false;
}



function getComments(){


	$commentquery = mysql_query("SELECT * FROM comments WHERE tutorialid='".$mtutorial['t_id']."' ORDER BY date") or die(mysql_error());


	$commentNum = mysql_num_rows($commentquery);

	echo "<h3 class=\"formtitle\">Current Comments</h3>\n";
	echo $commentNum . " comments so far (<a href=\"#post\">post your own</a>)\n";

	while($commentrow = mysql_fetch_row($commentquery)){

	$commentbb = BBCode($commentrow[4]);

		$commentDate = formatDate($commentrow[6]);

		echo "
		<p>$commentbb</p>
		<p>Posted by ";
		if($commentrow[3]){
		echo "<a href=\"$commentrow[3]\">$commentrow[2]</a> ";
		} else {
		echo "$commentrow[2] ";
		}
		echo "on $commentDate | #$commentrow[0]</p>
		";
		
	}
	
}

PHP:

As you se in the code this statement:

$db->rs_create("SELECT * FROM steps WHERE s_for_tutorial = '".$mtutorial['t_id']."' AND s_number IN (".implode(',', $loadsteps).")");
    $msteps = $db->rs_flush();

PHP:

Its working etc and functional..
Now im trying to add the same here on my function getComments

function getComments(){


    $commentquery = mysql_query("SELECT * FROM comments WHERE tutorialid='".$mtutorial['t_id']."' ORDER BY date") or die(mysql_error());

PHP:

But its not working with this ".$mtutorial['t_id'].", i need to echo that t_id from my tutorials table but how do i do that??


Please help me out, and please post here if you don't know what i mean, i can rewrite it and explain it hopefully!!

 

The variable $mtutorial doesn't exist inside your function unless you globalize it, or pass it in the arguments.

Try adding this line as first line inside your function.

global $mtutorial;
