Creating a product

[Taragon]

When creating a product, what would be the best way to add a line of code to an existing template?

Currently I'd like to add

<script type="text/javascript" src="clientscript/jquery/1.3/jquery-1.3.2.min.js"></script>

to the headerinclude template like this

<meta http-equiv="Content-Type" content="text/html; charset=$stylevar[charset]" />
<meta name="generator" content="vBulletin $vboptions[templateversion]" />
<if condition="$show['threadinfo']">
<meta name="keywords" content="<if condition="$threadinfo['taglist']">$threadinfo[taglist], </if>$threadinfo[prefix_plain_html] $threadinfo[title], $vboptions[keywords]" />
<meta name="description" content="<if condition="$pagenumber>1"><phrase 1="$pagenumber">$vbphrase[page_x]</phrase>-</if>$threadinfo[prefix_plain_html] $threadinfo[title] $foruminfo[title_clean]" />
<else /><if condition="$show['foruminfo']">
<meta name="keywords" content="$foruminfo[title_clean], $vboptions[keywords]" />
<meta name="description" content="<if condition="$pagenumber>1"><phrase 1="$pagenumber">$vbphrase[page_x]</phrase>-</if>$foruminfo[description_clean]" />
<else />
<meta name="keywords" content="$vboptions[keywords]" />
<meta name="description" content="$vboptions[description]" />
</if></if>

<!-- CSS Stylesheet -->
$style[css]
<if condition="is_browser('opera') AND !is_browser('opera', '8.0.1')">
<style type="text/css" id="vbulletin_opera8fix_css">
ul, ol { padding-$stylevar[left]:20px; }
</style>
</if>
<if condition="$show['editor_css']">
$editor_css
</if>
<!-- / CSS Stylesheet -->

<script type="text/javascript" src="$stylevar[yuipath]/yahoo-dom-event/yahoo-dom-event.js?v=$vboptions[simpleversion]"></script>
<script type="text/javascript" src="$stylevar[yuipath]/connection/connection-min.js?v=$vboptions[simpleversion]"></script>
<script type="text/javascript">
<!--
var SESSIONURL = "$session[sessionurl_js]";
var SECURITYTOKEN = "$bbuserinfo[securitytoken]";
var IMGDIR_MISC = "$stylevar[imgdir_misc]";
var vb_disable_ajax = parseInt("$vboptions[disable_ajax]", 10);
// -->
</script>
<script type="text/javascript" src="clientscript/vbulletin_global.js?v=$vboptions[simpleversion]"></script>
<if condition="$show['popups']"><script type="text/javascript" src="clientscript/vbulletin_menu.js?v=$vboptions[simpleversion]"></script></if>

<script type="text/javascript" src="clientscript/jquery/1.3/jquery-1.3.2.min.js"></script>

<if condition="$vboptions['externalrss']">
	<link rel="alternate" type="application/rss+xml" title="$vboptions[bbtitle] RSS Feed" href="external.php?type=RSS2" />
	<if condition="$show['foruminfo'] OR $show['threadinfo']">
		<link rel="alternate" type="application/rss+xml" title="$vboptions[bbtitle] - $foruminfo[title_clean] - RSS Feed" href="external.php?type=RSS2&amp;forumids=$foruminfo[forumid]" />
	</if>
</if>

	<plugins>
		<plugin active="1" executionorder="5">
			<title>test</title>
			<hookname>global_start</hookname>
			<phpcode><![CDATA[$find = '<if condition="$show['popups']"><script type="text/javascript" src="clientscript/vbulletin_menu.js?v=$vboptions[simpleversion]"></script></if>';
$replace = '<if condition="$show['popups']"><script type="text/javascript" src="clientscript/vbulletin_menu.js?v=$vboptions[simpleversion]"></script></if>

<script type="text/javascript" src="clientscript/jquery/1.3/jquery-1.3.2.min.js"></script>';
$vbulletin->templatecache['headinclude'] = str_replace($find, $replace, $vbulletin->templatecache['headinclude']);]]></phpcode>
		</plugin>
	</plugins>
