To my knowledge this should make 2 black squares, 10x10 one starting at 0,0 and the other at 10,10. It is currently making 1 black square at 0,0....or maybe 2 on top of each other at 0,0

 

Why isn't it? It is running the IFs correctly

[Barand]

is "x" a predefined constant?

[almightyegg]

In map1.php (the file that is included) it says:

$p1d3 = o;

$p2d3 = o;

$p3d3 = x;

$p4d3 = x;

$p5d3 = o;

$p6d3 = x;

$p7d3 = o;

$p8d3 = x;

$p9d3 = o;

etc...

 

That answer your question or not?

[Barand]

Those should be 'o', 'x'.

 

Your problem is you use imagecreate twice.

 

You should create 1 image at start, draw squares, output the image

[almightyegg]

Right....

So if I want 150 blacksquares to show, 15 per row, 10 rows, how do I do that?

Because no matter what I try it shows one 10x10 square

[almightyegg]

I'm done that. Though I'm not sure I have done it right/...

$im = imagecreate(10, 10);

if($p1d2 == x){
imagefilledrectangle($im, 0, 0, 10, 10, imagecolorallocate($im, 0, 0, 0));
}elseif($p == $p1d2){
imagefilledrectangle($im, 0, 0, 10, 10, imagecolorallocate($im, 255, 0, 0));
}elseif($p1d2 == v){
imagefilledrectangle($im, 0, 0, 10, 10, imagecolorallocate($im, 255, 0, 0));
}else{
imagefilledrectangle($im, 0, 0, 10, 10, imagecolorallocate($im, 255, 0, 0));
}

if($p3d1 == x){
imagefilledrectangle($im, 10, 10, 20, 20, imagecolorallocate($im, 0, 0, 0));
}elseif($p == $p3d1){
imagefilledrectangle($im, 10, 10, 20, 20, imagecolorallocate($im, 255, 0, 0));
}elseif($p3d1 == v){
imagefilledrectangle($im, 10, 10, 20, 20, imagecolorallocate($im, 255, 0, 0));
}else{
imagefilledrectangle($im, 10, 10, 20, 20, imagecolorallocate($im, 255, 0, 0));
}

if image is 10 x 10 all other squares are outside the image

 

<?php 

header("Content-type: image/png");
include "map1.php";

$im = imagecreate(150, 100);

if($p1d2 == 'x'){
imagefilledrectangle($im, 0, 0, 10, 10, imagecolorallocate($im, 0, 0, 0));
}
if($p3d1 == 'x'){
imagefilledrectangle($im, 10, 10, 20, 20, imagecolorallocate($im, 0, 0, 0));
}


imagepng($im);
imagedestroy($im);
?>

[Barand]

You shuld only allocate color once

 

<?php 

header("Content-type: image/png");
include "map1.php";

$im = imagecreate(150, 100);
$black = imagecolorallocate($im, 0, 0, 0);

if($p1d2 == 'x'){
imagefilledrectangle($im, 0, 0, 10, 10, $black);
}
if($p3d1 == 'x'){
imagefilledrectangle($im, 10, 10, 20, 20, $black);
}


imagepng($im);
imagedestroy($im);
?>

[almightyegg]

That just makes a solid black square 150x100 :-/

[almightyegg]

The problem is sorted. Thanks. But I have another now Instead of typing 150 ifs out I thought I would try and be clever and use a while to do it...

 

This is it:

$i = 1;
$h = 1;
while($i <> 16 && $h <> 11){
$p = ${"p" . $i . "d" . 1};
$f = ($i-1)*10;
$s = $i*10;
$g = ($h-1)*10;
$r = $h*10;

$black = imagecolorallocate($im, 0, 0, 0);
$red = imagecolorallocate($im, 255, 0, 0);
$brown = imagecolorallocate($im, 255, 255, 255);
$turq = imagecolorallocate($im, 153, 255, 255);
if($p == x){
imagefilledrectangle($im, $f, $g, $s, $r, $black);
}elseif($p == v){
imagefilledrectangle($im, $f, $g, $s, $r, $turq);
}elseif($p == o){
imagefilledrectangle($im, $f, $g, $s, $r, $brown);
}

if($i == 15 && $h == 10){
$h = $h+1;
$i = $i+1;
}elseif($i == 15){
$i = 0;
$h = $h+1;
}else{
$i = $i+1;
}

}

$i represents the 15 columns

$h represents the 10 rows

 

 

Instead of showing what it's meant to it shows:

 

What is the problem??
