A java tutorial would be really awesome! And it is not completely not web-related.

It dies at the point where it does: $sql = "SELECT * FROM topic WHERE name = 'Rants'"; if(!($result = mysql_query($sql, $con))) die("<br />" . mysql_error($con) . "<br />"); if (!($row = mysql_fetch_assoc($result))) die("<br />" . mysql_error($con) . "<br />"); if($row['name'] != "Rants"){ $sql = "INSERT INTO topic(parent_forum, name, description) VALUES(1, 'Rants', 'Things you don't like about our site.')"; mysql_query($sql, $con); }

Why is this code not working? It should display the forums and their topics, but instead one of the "die()" functions executes, and I do not know why. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><style type="text/css"> body{ background: #3399FF; font-family: Arial; } td.center{ text-align: center; } a{ text-decoration: none; color: black; font-family: Arial; } a:hover{ color: white; text-decoration: underline; } a:visited{ color: purple; }</style><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /><title>REDEYEGAMEZ</title></head><body><table width="100%"> <td width="33%"></td> <td width="33%" class="center"><h1>FORUM</h1> <p>This is the redeyegamez forum.

ASP.NET is microsoft, and that should be enough for you not to learn it.

It would be really cool if you were to give tutorials on things like C++!

Thanks, I would not have thought of that!

Is it possible to use a php form to edit xml? I was thinking something like this. <html><head><title>xml editor</title></head><body><form method="post"><input type="text" name="xml_code" /><input type="submit" value="change xml file" /></form><?php$fp = fopen("edited.xml", "w");fwrite($fp, $_POST['xml_code']);?></body></html>

you can just do it by embedding it in html <embed src="foo.mp3" />

<form name="myform" id="myform"><input type="text" name="mytext" id="mytext" /><input type="submit" value="enter text" /></form><script type="text/javascript"><!--var text = document.myform.mytext.value;document.write(text);--></script> Why does this not work?
