GingerRobot Posted January 8, 2009 Share Posted January 8, 2009 The problem is that you're telling the browser that the content it is expected to receive is a png image. You then try and display HTML too, which it has no idea what to do with. You need to move the image creation to a separate file, and display it using an HTML image tag.

GingerRobot Posted January 8, 2009 Share Posted January 8, 2009 A browser is capable of displaying lots of different formats - text files, images, HTML pages etc. You're asking it to display two different types simultaneously - a png image and HTML. It can't do that. To display images in an HTML page, you must use the image tag. You need to move the image creation to a separate file. Let's call it image.php: <?php session_start(); include("dbconfig.php"); $code =$_SESSION['ran_barcode']; //echo "$code"; if (!$_SESSION['loggedIn']) { header("location:login.php"); die (); } else { function UPCAbarcode($code) { $lw = 2; $hi = 100; $Lencode = array('0001101','0011001','0010011','0111101','0100011', '0110001','0101111','0111011','0110111','0001011'); $Rencode = array('1110010','1100110','1101100','1000010','1011100', '1001110','1010000','1000100','1001000','1110100'); $ends = '101'; $center = '01010'; /* UPC-A Must be 11 digits, we compute the checksum. */ if ( strlen($code) != 11 ) { die("UPC-A Must be 11 digits."); } /* Compute the EAN-13 Checksum digit */ $ncode = '0'.$code; $even = 0; $odd = 0; for ($x=0;$x<11;$x++) { if ($x % 2) { $odd += $ncode[$x]; } else { $even += $ncode[$x]; } } $code.=(10 - (($odd * 3 + $even) % 10)) % 10; /* Create the bar encoding using a binary string */ $bars=$ends; $bars.=$Lencode[$code[0]]; for($x=1;$x<6;$x++) { $bars.=$Lencode[$code[$x]]; } $bars.=$center; for($x=6;$x<12;$x++) { $bars.=$Rencode[$code[$x]]; } $bars.=$ends; /* Generate the Barcode Image */ $img = ImageCreate($lw*95+30,$hi+30); $fg = ImageColorAllocate($img, 0, 0, 0); $bg = ImageColorAllocate($img, 255, 255, 255); ImageFilledRectangle($img, 0, 0, $lw*95+30, $hi+30, $bg); $shift=10; for ($x=0;$x<strlen($bars);$x++) { if (($x<10) || ($x>=45 && $x<50) || ($x >=85)) { $sh=10; } else { $sh=0; } if ($bars[$x] == '1') { $color = $fg; } else { $color = $bg; } ImageFilledRectangle($img, ($x*$lw)+15,5,($x+1)*$lw+14,$hi+5+$sh,$color); } /* Add the Human Readable Label */ ImageString($img,4,5,$hi-5,$code[0],$fg); for ($x=0;$x<5;$x++) { ImageString($img,5,$lw*(13+$x*6)+15,$hi+5,$code[$x+1],$fg); ImageString($img,5,$lw*(53+$x*6)+15,$hi+5,$code[$x+6],$fg); } ImageString($img,4,$lw*95+17,$hi-5,$code[11],$fg); /* Output the Header and Content. */ header("Content-Type: image/png"); ImagePNG($img); } UPCAbarcode($code); } ?> You then call the file in an image tag: ... <img src="image.php" /><br /> <input type="text" name="hello" value="hello"> ...
