multi image print

[The1corrupted]

I'm having issues with my own multi-image print...

[PHP]//Ifs that make the correct image...
if ($nimg == 0) { $nimg="nfalse.g if";
} else { $nimg="ntrue.gi f"; }

if ($simg == 0) { $simg="sfalse.g if";
} else { $simg="strue.gi f"; }

if ($eimg == 0) { $eimg="efalse.g if";
} else { $eimg="<etrue.g if"; }

if ($wimg == 0) { $wimg="wfalse.g if";
} else { $wimg="wtrue.gi f"; }

if ($uimg == 0) { $uimg="ufalse.g if";
} else { $uimg="utrue.gi f"; }

if ($dimg == 0) { $dimg="dfalse.g if";
} else { $dimg="dtrue.gi f"; }
[/PHP]

Then I try to embed the image names...

[PHP]
echo " <table border='0' align='center' cellspacing='0' >
<tr><td><img src='images/blank.gif'></td><td><img src='images/".$nimg."'> </td><td><img src='images/".$uimg."'> </td></tr>
<tr><td><img src='images/".$wimg."'> </td><td><img src='images/blank.gif'></td><td><img src='images/".$eimg."'> </td></tr>
<tr><td><img src='images/".$dimg."'> </td><td><img src='images/".$simg."'> </td><td><img src='images/blank.gif'></td></tr>";
[/PHP]

I have split this thread. You will receive better responses this way.

What exactly is the issue you are having?

This has been the result of two things breaking at once... When I try to echo out the images, it all goes to one side or the other rather than actually comparing it to the table... Also, it breaks my session variables and they hence don't change where as normally they would..

Basically, I suspect this might not be working:

[PHP]$x=$_SESSION['xcoord'];
$y=$_SESSION['ycoord'];
$z=$_SESSION['zcoord'];

$summon=mysql_q uery("SELECT *
FROM rooms
WHERE ns='$x'
AND ew='$y'
AND ud='$z'");
$ray=mysql_fetc h_array($summon );

$nimg=$ray[3];
$simg=$ray[4];
$eimg=$ray[5];
$wimg=$ray[6];
$uimg=$ray[7];
$dimg=$ray[8];[/PHP]

Are your coordinates in the database as VARCHAR, INT, or FLOAT?
You might not want to have them in 's if they aren't VARCHAR.

I've just narrowed it down. That entire section in the first post is all bad. The coords are actually TINYINTs and are up to three digits long... Sorry for the mistake.

Okay, nevermind. I totally fixed it. With this little snippet of code..

[PHP]
if ($ray[3] == 0) { echo "<div style='position :absolute; top:100; left:480; z-index:1;'>
<img src='images/ntrue.gif' height='30px' width='30px'>
</div>";
} elseif ($ray[3] == 1) { echo "<div style='position :absolute; top:100; left:480; z-index:1;'>
<img src='images/ntrue.gif' height='30px' width='30px'>
</div>";[/PHP]

<img src='images/ntrue.gif' height='30px' width='30px'>
</div>";[/PHP]

Heads up: both cases show the same image.

[The1corrupted]

Actually, they should, but the first one didn't and it managed to completely break my coordinate system...

[Motoma]

I mean, line by line these are the same thing:

<div style='position :absolute; top:100; left:480; z-index:1;'>
<img src='images/ntrue.gif' height='30px' width='30px'>
</div>

<div style='position :absolute; top:100; left:480; z-index:1;'>
<img src='images/ntrue.gif' height='30px' width='30px'>
</div>

You don't need the if statement.

Gah! So you're right... Thanks for catching that error.
