Inserting a block of JavaScript code into a PHP script -

-

a friend of mine wanted me gather statistics website gave him following code insert in page footers:

<div>     <script>        var wandtopsitesuserid;        match = document.cookie.match(new regexp("wandtopwildlifesites" + '=([^;]+)'));        if (match)           wandtopsitesuserid = match[1];        else {           wandtopsitesuserid = (+new date * math.random()).tostring(36).slice(2, 12);           document.cookie = 'wandtopwildlifesites=' + wandtopsitesuserid + '; expires=tue, 1 jan 2030 00:00:00 utc; path=/';        }         document.write('<div style="visibility: hidden;"><a href="http://www.www.fxxxxx.com/"><img src="http://xxxxxx.azurewebsites.net/log/logvisit/?siteid=2&userid=' + wandtopsitesuserid + '&pagename=' + location.pathname + '" alt="wand top wildlife sites" /></a></div>');     </script>  </div>

what didn't know he's using php , know absolutely nothing php. when attempts insert code php script, gets following error:

string(125) "smarty error: [in globalcontent:footer line 9]: [plugin] unknown tag - 'wandtopsitesuserid' (core.load_plugins.php, line 198)" string(137) "smarty error: [in globalcontent:footer line 9]: syntax error: unrecognized tag 'wandtopsitesuserid' (smarty_compiler.class.php, line 590)"

not knowing php, have idea how fix this.

he uses samrty template engine requires escape javascript encapsulating within {literal}...{/literal}:

<div>     {literal}     <script>        var wandtopsitesuserid;        match = document.cookie.match(new regexp("wandtopwildlifesites" + '=([^;]+)'));        if (match)           wandtopsitesuserid = match[1];        else {           wandtopsitesuserid = (+new date * math.random()).tostring(36).slice(2, 12);           document.cookie = 'wandtopwildlifesites=' + wandtopsitesuserid + '; expires=tue, 1 jan 2030 00:00:00 utc; path=/';        }         document.write('<div style="visibility: hidden;"><a href="http://www.www.fxxxxx.com/"><img src="http://xxxxxx.azurewebsites.net/log/logvisit/?siteid=2&userid=' + wandtopsitesuserid + '&pagename=' + location.pathname + '" alt="wand top wildlife sites" /></a></div>');     </script>     {/literal}  </div>
