square instead of number

[thosecars82]

Hello

I do not know why but this code seems to work fine only in my xampp local insallation but not in the remote server. I just see a black square instead of the number 0000000 when I run this code in the remote server through the link http://www.arreglaordenador.com/numberimage.php

 

and the code in numberimage.php is:

 
<?php
$fontDir = $rootPath . "fonts\\";
$fn = (isset($_GET['fn'])) ? $_GET['fn'] : "ARIAL.ttf";
$fs = (isset($_GET['fs'])) ? $_GET['fs'] : 10;
$maxWidth = 80 * $fs;

//$colorArray = array ("red", "green", "blue", "cyan", "magenta", "yellow", "black", "white", "gray");
  $colorArray = array ("black", "black", "black", "black", "black", "black", "black", "black", "black");
$color = (isset($_GET['color'])) ? $colorArray[$_GET['color']] : $colorArray[rand(0, ];
$txt = (isset($_GET['txt'])) ? $_GET['txt'] : "0000000";
$coords = imagettfbbox($fs, 0, $fontDir . $fn, $txt);
$w = abs($coords[4]) + 8;
$h = abs($coords[5]) + 8;
$img = imagecreatetruecolor($w, $h);
$red = imagecolorallocate($img, 255,0,0);
$green = imagecolorallocate($img, 0,255,0);
$blue = imagecolorallocate($img, 0,0,255);
$cyan = imagecolorallocate($img, 0,255,255);
$magenta = imagecolorallocate($img, 255,0,255);
$yellow = imagecolorallocate($img, 255,255,0);
$black = imagecolorallocate($img, 0,0,0);
$white = imagecolorallocate($img, 255,255,255);
$gray = imagecolorallocate($img, 127,127,127);
$fill = ($color == "white") ? $black : $white;
imagefill($img, 0, 0, $fill);
$position = 4;
if (isset($_GET['position'])) $position = $_GET['position']; 

imagettftext($img, $fs, 0, 0, $h-$position, $$color, "$fontDir$fn", $txt);

header("content-type: image/jpeg");
imagejpeg($img, "", 100);
imagedestroy($img);
?>

 

Does any of you have any suggestion?

Thanks

is your paths for your fonts proper ? thats the only thing I can think of which might go wrong.

For debugging purposes, add the following two lines of code immediately after the first opening <?php tag and temporarily comment out the header() and imagejpeg() statements -

 

ini_set("display_errors", "1");
error_reporting(E_ALL);

 

I see three possible problems -

 

1) You are not defining $rootPath

2) You are using a \\ as a path separator, which on a UNIX/LINUX operating system has no meaning. You should always use / as a path separator (under Windows, php converts it to a \ before it passes it to the operating system.)

3) Under UNIX/LINUX, you generally must use an absolute file system path for the font files.

 

There are about a half dozen more possible problems which the error_reporting/display_errors lines should uncover.

Ok, thanks for those two lines for debugging. They helped me to know the problem was the $rootPath variable. Now, if you see the number is displayed, however the background is displayed in black color making the number very difficult to see. However, I do not understand why this just happens remotely and not locally.

 

<?php
$fontDir = "fonts/";
$fn = (isset($_GET['fn'])) ? $_GET['fn'] : "arial.ttf";
$fs = (isset($_GET['fs'])) ? $_GET['fs'] : 10;
$maxWidth = 80 * $fs;

$colorArray = array ("red", "green", "blue", "cyan", "magenta", "yellow", "black", "white", "gray");
// $colorArray = array ("black", "black", "black", "black", "black", "black", "black", "black", "black");
$color = (isset($_GET['color'])) ? $colorArray[$_GET['color']] : $colorArray[rand(0, ];
$txt = (isset($_GET['txt'])) ? $_GET['txt'] : "0000000";
$coords = imagettfbbox($fs, 0, $fontDir . $fn, $txt);
$w = abs($coords[4]) + 8;
$h = abs($coords[5]) + 8;
$img = imagecreatetruecolor($w, $h);
$red = imagecolorallocate($img, 255,0,0);
$green = imagecolorallocate($img, 0,255,0);
$blue = imagecolorallocate($img, 0,0,255);
$cyan = imagecolorallocate($img, 0,255,255);
$magenta = imagecolorallocate($img, 255,0,255);
$yellow = imagecolorallocate($img, 255,255,0);
$black = imagecolorallocate($img, 0,0,0);
$white = imagecolorallocate($img, 255,255,255);
$gray = imagecolorallocate($img, 127,127,127);
$fill = ($color == "white") ? $black : $white;
imagefill($img, 0, 0, $fill);
$position = 4;
if (isset($_GET['position'])) $position = $_GET['position']; 

imagettftext($img, $fs, 0, 0, $h-$position, $$color, "$fontDir$fn", $txt);

header("content-type: image/jpeg");
imagejpeg($img, "", 100);
imagedestroy($img);
?>

 

Thanks
