//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');

  $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 ($bars[$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");

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.

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">
...

 

Any clearer?
