"Deprecated" warning

Hi,
you could fix that warning editing wp-code-highlight.php files located in
wp-content/plugins/wp-code-highlight/wp-code-highlight.php
Comment line 67-68 and add this line:

//return preg_replace("/<pre(.*?)>(.*?)<\/pre>/ise",
//      "'<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$2').'</pre>'", $content);

return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$m[2]').'</pre>'; },$content);

Hi,

Just updated my PHP version from 5.4 to 7 and I was getting that error too. Your solution, @simone-camporeale, didn’t completely worked for me. I was getting literally this in each pre:

$m[2]

So I have modified simone.camporeale solution, and got this one that is working for me:

return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).''; },$content);

Note it’s almost the same, but modifying a little bit the pre tag’s class and removing the apostrophes in the wch_strpslashes() parameter.

EDIT: sorry for editing a lot. First time posting here and I was trying to figure out how to correctly put code in the code blocks.

EDIT2: btw, I had to check all my code snippets since, on some, some symbols like & or > were automatically changed to the HTML name (& amp; and & gt; respectively)

Hi @pauguillamon, noticed that your snippet is missing the closing element in case others are using your patch.

return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).''; },$content);

@michael Visser: Sorry, but you also forgot the closing pre tag.

Here’s the code that works for me ATM.

//	return preg_replace("/<pre(.*?)>(.*?)<\/pre>/ise",
//		"'<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$2').'</pre>'", $content);
return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).'</pre>'; },$content);

*headsmack* Thanks @hoelli, we’ll get there on the third attempt (or more) ??
