Topic: Php warning: undefined variable $descr in html2wordml.php

Hi,

i got the error

[08-Mar-2021 16:09:53 Europe/Paris] PHP Warning:  Undefined variable $descr in [...]/PhpDocx/classes/HTML2WordML.php on line 1455
[08-Mar-2021 16:09:53 Europe/Paris] PHP Warning:  Undefined variable $descr in [...]/PhpDocx/classes/HTML2WordML.php on line 1457

where i use

require_once(__DIR__ . '/PhpDocx/classes/CreateDocx.php');

$docx = new CreateDocx();
$docx->embedHTML($html);

$cheminDocx = DIR_TMP . getUniqId();
$docx->createDocx($cheminDocx);

$html got the value

<p><img src="data:image/png;base64,[...]" alt="" width="321" height="320" />texte</p>

if the link is not dead, you can check the base64 on https://textup.fr/534353xg (it's just a duck meme, any base64 img would have the error)

I'm using Premium 11

Regards.

Hello,

Recent versions of PHP throws a Warning when trying to use a not initialized variable (previous PHP versions throw a Notice). Please apply the following change that is already included in the current testing version of phpdocx that will be included in the next release of phpdocx, that inits that $descr variable always to hide the warning when using a base64 image:

Edit HTML2WordML.php and after line 1291 in the classic package adds the following line:

$descr = 'image' . uniqid(mt_rand(999, 9999));

Instead of the following lines:

case 'img':
case 'svg':
  $this->wordML .= $this->closePreviousTags($depth, $nodo['nodeName']);
  if (isset($nodo['attributes']['src']) && strstr($nodo['attributes']['src'], 'base64,')) {

The code to be used after the previous change is the following:

case 'img':
case 'svg':
  $this->wordML .= $this->closePreviousTags($depth, $nodo['nodeName']);
  $descr = 'image' . uniqid(mt_rand(999, 9999));
  if (isset($nodo['attributes']['src']) && strstr($nodo['attributes']['src'], 'base64,')) {

This minor change should avoid that warning when using a base64 image and the newest versions of PHP.

Regards.
