Please help with logical or syntactical problem!

[gilbert.havlik@gmail.com]

Greetings!

Please be so kind and take a few minutes, I believe any mind other than
mine can solve this. I am writing a game. As you wander through the
gameworld, you may come upon signs. I have a DB where the signs are
listed, with "longitude" and "latitude". Anytime someone takes a step,
I want to show a grid where any square can be reached within 3 steps.
And if there's a sign in one grid, I want to show it, so the player can
walk directly to it.
In my test environment I have three signs located very close and around
to 100|50. The routine I wrote below works. But it only gives me the
last of the three signs. And I just can't tell if it's a logical
problem with my two loops and the foreach, or if there's a hook with
PHP itself.

So why does it only show me the last of the three signs????
Also, how can I make this with POST?
And I know this is messy, how could I make it faster?

I am grateful for any pointer!

Helpless regards, Gilbert.

PS: $lire is for x, $raru is for y

<pre>
$signr = $db->get_results("S ELECT text,longitude, latitude FROM signs
WHERE longitude>$lire-4 and longitude<$lire +4 and latitude>$raru-4 and
latitude<$raru+ 4",ARRAY_A);

for ($j = 3 ; $j <= 9 ; $j++) {
for ($i = 3 ; $i <= 9 ; $i++) {
$cps[$i][$j] = "<td width=30 height=30 align=center valign=center>< a
href='main.php? dir=$i$j'><img src='images/";
$icon = "gravel.gif ";
if (is_array($sign r)) {
reset($signr);
foreach($signr as $check) {
$x = $lire+$i-6;
$y = $raru+$j-6;
if ($check['longitude'] == $x && $check['latitude'] == $y ) {
$icon = "scroll.gif ";
}
else $icon = "gravel.gif ";
}
}
$cps[$i][$j] .= $icon;
$cps[$i][$j] .= "' style='border:2 px outset black'
border=0></a></td>";
}
}
// $cps[6][6] = "<td></td>";
$compass = "<form action='main.ph p' method='POST'>" ;
$compass .="<table cellspacing=0 cellpadding=0
background='ima ges/xmap.jpg'>";
$compass .= "<tr><td></td><td></td><td></td> ".$cps[6][3]."
<td></td><td></td><td></td></tr>\n";
$compass .= "<tr><td></td><td></td>
".$cps[5][4].$cps[6][4].$cps[7][4]."<td></td><td></td></tr>\n";
$compass .= "<tr><td></td>
".$cps[4][5].$cps[5][5].$cps[6][5].$cps[7][5].$cps[8][5]."<td></td></tr>\n";
$compass .=
"<tr>".$cps[3][6].$cps[4][6].$cps[5][6].$cps[6][6].$cps[7][6].$cps[8][6].$cps[9][6]."</tr>\n";
$compass .= "<tr><td></td>
".$cps[4][7].$cps[5][7].$cps[6][7].$cps[7][7].$cps[8][7]."<td></td></tr>\n";
$compass .= "<tr><td></td><td></td>
".$cps[5][8].$cps[6][8].$cps[7][8]."<td></td><td></td></tr>\n";
$compass .= "<tr><td></td><td></td><td></td> ".
$cps[6][9]."<td></td><td></td><td></td></tr>\n";
$compass .= "</table></form>";
unset($cps);

Re: Please help with logical or syntactical problem!

I wrote that part again. This time the $cps is premade, and I only
foreach $signr and replace the $cps where necessary. Learning by
doing...
Thanks anyway to anyone who read it.
Greets, Gilbert.
