Hi, i have an error in this code. It simply displays nothing. I have pasted it on a paste website.

One thing (that doesn't cause the problem you have) is that you have one more <table> than </table>.

As a suggestion, rather than echo'ing a load of standard html, do it like this:

?>
<table width = '770' border = '1'>
<tr>
<td>Credits:<?=$userinfo["credits"]?></td>
<td>Power:<?=$userinfo["power"]?></td>
<td>Metal:<?$userinfo["metal"]?></td>
<tr>
<td><tr><td width="150" align= "center" bgcolor= "#cccccc">
Main</td>

The reason for doing it this way is that the php parser doesn't need an echo to output pure html, anything outside the <? ?> tags gets streamed as html. Second, if you have a decent editor (like ACE HTML Pro 5, or the fantastic freeware TSW Webcoder 4) it will correctly parse the html to make it easy to spot the errors.

Without access to your server, so that the db calls will work, the only obvious coding not done accoding to the manual is the include on line 4:

include'lord.php';

which should read:

include ('lord.php');

Any use?

Actually, it is valid according to the manual (see the basic example on the [man]include[/man] page). "include" is a statement rather than a function.

You say you get a "blank page". Is this really a blank page (empty response), or is it HTML that doesn't render to anything visible?

Thanks, i have worked it out. At title, i had the "; of the echo, before <title> so it never finsihed the title 🙂

Again thnks to those who helped.

"global" declarations go inside functions, not outside. In PHP, variables are local by default, and if you want a function to use a global variable, you have to tell it so (using the [man]global[/man] statement).

So instead of using the global $userinfo array (because you didn't tell it to), main() is trying to use its own local $userinfo variable, which doesn't exist yet because it hasn't been given a value. So it complains.
