בעיה בפורום רקורסיבי- הצגת הפורום
אוקי, זה הקוד שהכנתי:
קוד PHP:
<?php
header("Content-type: text/html; charset=utf8");
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html dir="rtl">
<head>
<title>פורום!</title>
<style type="text/css">
div.cat_main
{
margin-top: 8px;
color: #9F6363;
}
div.cat_sub
{
margin-right: 20px;
color: #CFA8A8;
}
.vis
{
display : block;
}
.nvis
{
display : none;
}
</style>
<script type="text/javascript">
<!--
function disNabale(divObjects)
{
if(document.getElementById(divObjects).className== 'vis')
document.getElementById(divObjects).className='nvi s';
else
document.getElementById(divObjects).className='vis ';
}
//-->
</script>
</head>
<body>
<?php
include('db.php');
function printTreePost($deep, $id)
{
global $cats;
foreach($cats[$id] as $key => $cat)
{
if($key == 0)
{
echo '<div class="cat_main">'.$cat['title'].'</div>';
}
$nDeep = $deep * 20;
echo '<div style="margin-right: '.$nDeep.'px; color: #CFA8A8;" >'.$cat['title'].'</div>'."\n";
if(isset($cats[$cat['id']]))
printTreePost(++$deep, $cat['id']);
}
}
$start = mysql_query('SELECT * FROM `forum_messeges` ORDER BY `parent`') OR die('Error on query MySQL said: '.mysql_error());
$post = 1;
while($info = mysql_fetch_array($start))
{
if($info['parent'] == 0)
{
$cats[$info['id']][0]['parent'] = TRUE;
$cats[$info['id']][0]['title'] = $info['title'];
$cats[$info['id']][0]['id'] = $info['id'];
//all over information.. here
continue;
}
$key = count($cats[$info['parent']]);
$cats[$info['parent']][++$key]['parent'] = FALSE;
$cats[$info['parent']][++$key]['title'] = $info['title'];
}
foreach($cats as $sub)
{
printTreePost(1, $sub);
}
?>
</div>
</body>
</html>
וזה מחזיר לי את ההודעות שגיאה הבאות:
Notice: Undefined index: 2 in C:\Apache2\htdocs\lowar\forum_display.php on line 79
Notice: Undefined index: 3 in C:\Apache2\htdocs\lowar\forum_display.php on line 79

Warning: Illegal offset type in C:\Apache2\htdocs\lowar\forum_display.php on line 54

מישהו יכול לפתור את הבעיה או לכוון אותי לפיתרון?
