[RESOLVED] PHP and GD lib help

aksdad

I am a newbie at PHP and was looking through codes and made something up today.
The problem is it doesn't work at all and doesn't show any errors too.
This is supposed to generate a gamer tag after taking values from the db.
Please check and tell me how to correct the errors.
This is my first time here 🙂
Thanks in advance🙂

Is display_errors set to On and error_reporting set to E_ALL?

aksdad

How do I check that?

bradgrafelman

Easy way is to look at a [man]phpinfo/man output.

aksdad

error_reporting 6135 6135
display_errors Off Off

Yup display errors are off.
Could you check the syntax/missing stuff 'coz I think I must've done a mistake there

bradgrafelman

Yup, you've got a parse error:

G:\php>php -l test.php
PHP Parse error:  syntax error, unexpected T_STRING in test.php on line 26

Your problem is here:

$cardavatar = '<?php echo $setting['site_url'];?>/uploads/avatars'$row['avatar'];

You're trying to start another set of PHP tags and [man]echo/man (e.g. output) some data in the middle of a string. If you just want to get the value of $setting['site_url'] at that point in the string, then you should use concatenation:

$cardavatar = $setting['site_url'] . '/uploads/avatars' . $row['avatar'];

The period is used as a concatenation operator.

EDIT: Also, while developing applications, you should turn display_errors on (either in php.ini or in a .htaccess file if using Apache).

On your production server, turn on log_errors and set the error_log directive to store all PHP errors in a file for later review.

Thanks for that but it still doesn't come.
It displays a invalid image file.

Sorry for the other post.
Its working now just the text isnt coming up in the image.

bradgrafelman

Can you post a fresh copy of your code?

aksdad

They ain't many changes I just hardlinked a few things :

<?php
// mySQL information
$server = 'localhost';                   // MySql server
$dbusername = 'xxx';                      // MySql Username
$password = 'xxx' ;                         // MySql Password
$database = 'xxxx';                  // MySql Database

// The following should not be edited
  $con = mysql_connect("$server","$dbusername","$password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("intergal_arcade", $con);

$user = $_GET['name']; //sets the name specified after name= as variable '$user'

$q = mysql_query("SELECT username, plays, points, avatar,favourites FROM ava_users WHERE username='$user' LIMIT 1"); //this will need modified to fit your setup

//$r = @mysqli_query($con,$q); //this will need modified to fit your setup
$row = mysql_fetch_array($q);

$cardname = $row['username'];
$cardplays = $row['plays'];
$cardpoints = $row['points'];
$cardavatar = 'http://www.intergalacticwars.info/games/uploads/avatars/' . $row['avatar']; 
$cardfavourite = $row['favourites']; 
$rImg = ImageCreateFromPNG('http://www.intergalacticwars.info/games/cardback.png');
$white = imagecolorallocate($rImg, 255, 255, 255);
$grey = imagecolorallocate($rImg, 128, 128, 128);
$black = imagecolorallocate($rImg, 0, 0, 0);
$font = 'http://www.intergalacticwars.info/games/arial.ttf';
$src = ImageCreateFromPNG($cardavatar); //loads avatar image to be edited (from the variable)

imagecopyresized($rImg, $src, 4, 4, 0, 0, 60, 60, 60, 60);
// Add the username
imagettftext($rImg, 20, 0, 129, 88, $grey, $font, $cardname);
// Add the EXP
imagettftext($rImg, 20, 0, 129, 112, $grey, $font, $cardplays);
// Add the rank
imagettftext($rImg, 20, 0, 129, 136, $grey, $font, $cardpoints);
// Add the scores
imagettftext($rImg, 20, 0, 129, 161, $grey, $font, $cardfavourite);

header('Content-type: image/png');
imagepng($rImg);
if (!mysql_query($q,$con))
  {
  die('Error: ' . mysql_error());
  }

mysql_close($con);
?>

Is 'www.intergalacticwars.info' your server (e.g. the same server this script is being run on)? If so, you should not use URLs to include local files on the same server. Instead, use a local file path (absolute or relative) to the files.

If that doesn't fix it, try commenting out the header() and call to imagepng() and then enabling display_errors (if there are no parse errors, you can enable this setting on-the-fly via [man]ini_set/man) to see if PHP is trying to warn you about something going wrong.

EDIT: Also, set your error_reporting to E_ALL (again, without parse errors, you can use [man]error_reporting/man to change this value on-the-fly) to make sure you can see every possible error PHP is trying to warn you about.

aksdad

I just want to confirm is it imagefttext or imagettftext?

aksdad

Something Weird : I changed the cardback.png's black background to transparent it appears fine :cardback.png
But with the script it looks like this : http://www.intergalacticwars.info/games/gamertag.php?name=eXo
