I currently changed a machine application, so the bar code image no longer appears. The PHP version of this new machine is newer, I've tried changing the image call but nothing happens. How could I resolve?

   <?php
      echo "<IMG src='barras.php?num=" .$codigobarras." '>";             
   ?>

Barcode (bar.php)

<?

Header("Content-type: image/jpeg");

$bf = 1;
$ab = 50;
if ($bf == "")
{
    $tamxt = 1;
    $tamxl = 3;
}
else
{
    $tamxt = $bf;
    $tamxl = ($bf * 2) + 1;
}   

if ($ab == "")
    $tamy = 50;
else
    $tamy = $ab;

$aux_len = strlen($num)%2;

if ($aux_len != 0)
    $aux_len = (strlen($num) + 1) / 2;
else
    $aux_len = strlen($num) / 2;

$aux_tamx = ((6 * $tamxt + 4 * $tamxl) * $aux_len) + (6 * $tamxt) + $tamxl;


$im = ImageCreate($aux_tamx, $tamy);

$white = ImageColorAllocate($im,255,255,255);

Resize image with CSS Error fetching external site content

score 2 · Answer 1

There are three possible issues that may have caused the crash:

You used <? instead of <?php , I recommend that you always use <?php .

You used $num instead of $_GET['num']

To solve this problem, add this to the beginning of the script:

    <?php
    $num = $_GET['num'];

    Header("Content-type: image/jpeg");

    $bf = 1;
    $ab = 50;
    if ($bf == "")
    {
       $tamxt = 1;
       $tamxl = 3;
    }
    else
    {
       $tamxt = $bf;
       $tamxl = ($bf * 2) + 1;
    }

GD library is disabled.

The GD library is responsible for the functions imagecreate , imagecolorallocate , etc. To activate it you will need to configure it in php.ini , search in php.ini a line similar to this:

;extension=php_gd2.dll

Remove the ; from the beginning and save the file, if this line does not exist then add this to the file:

extension=php_gd2.dll

If you are using a Debian or Ubuntu distribution (linux servers) then you should also run this line in the terminal:

$ sudo apt-get install php5-gd

(However I believe that GD is already installed, since it previously worked).

After this restart the server and retry the script.

"Debugging" script

If none of this works, then you can try to test your file because it can be a problem on your server that only you can detect, to "debug" your script do the following:

Comment the header like this:
```
    <?php
    $num = $_GET['num'];

    //Header("Content-type: image/jpeg");
```
- Open your file directly in the web-browser / browser without using <img> , something like:
  
  link
  
  You will probably have some error, please report this error in your question or comment here.

HTML and PHP hint

Your php looks like this:

echo "<IMG src='barras.php?num=" .$codigobarras." '>";

When run it does this for example:

<IMG src='barras.php?num=5 '>

See that there was a space at the end, although it does not affect your script, this does not seem right. I also recommend:

Use apostrophes for PHP and HTML pro tags
When using echo use , instead of points
Use html tags in minuscule

It should look like this:

echo '<img src="barras.php?num=', $codigobarras, '">';

These tips will not make a big difference, but will help make the code a little better to work with.
