Dynamic Signature breaks with hyphens in album name Options

[gotroot801]

Any time I have a song whose album contains a hyphen (i.e.: "Genesis Archive 1967-1975"), I get the following errors from the PHP script when attempting to display the image:

CODE

Warning: imagettftext() [function.imagettftext]: Problem rendering glyph in /[...]/signature.php on line 240

Warning: Cannot modify header information - headers already sent by (output started at /[...]/signature.php:240) in /[...]/signature.php on line 327

Warning: Cannot modify header information - headers already sent by (output started at /[...]/signature.php:240) in /[...]/signature.php on line 331

Warning: Cannot modify header information - headers already sent by (output started at /[...]/signature.php:240) in /[...]/signature.php on line 332

Warning: Cannot modify header information - headers already sent by (output started at /[...]/signature.php:240) in /[...]/signature.php on line 333

At that point, it starts dumping out the PNG headers like it normally would.

Of course, the only workaround I can think of is to just not play albums with hyphens in them, but since I don't know enough PHP to figure out how to get around this (or even to just suppress the errors), I was hoping someone here might.

EDIT: I'm able to suppress the warning by throwing a @ in front of the whole imagettftext function (line 233), but that's less than optimal - it starts drawing the album title, but stops as soon as it hits the hyphen.

Try different font or use a function to strip/replace them with some other character.

The font didn't change things (I think the psge parses - as a mathematical operand), but I was able to find a workaround and made the following (admittedly ugly) change to signature.php at around line 194:

CODE

  if(strlen($SONG['album'])>0) {
    $alb = "$SONG[album]";
    if(strlen($SONG['year'])>0) {
      $alb .= " ($SONG[year])";
      $alb_temp = str_replace("-", "–", $alb);
      $alb = $alb_temp;
    }
  } else {
    $alb = "";
  }
