Find Replace into Template PlugIn Code

[SorentoUltimate]

Hi all,

in vb3 i use that code to make changes to templates (parse_templates hook)

PHP Code:

    require_once(DIR . '/includes/adminfunctions_template.php'); 

    $string_fnd = compile_template('<if condition="$show[\'contactus\']"><a href="$vboptions[contactuslink]" rel="nofollow" accesskey="9">$vbphrase[contact_us]</a> -</if>'); 
    $string_add = fetch_template('terrabyter_about_us_footer_link'); 
    $vbulletin->templatecache['footer'] = str_replace($string_fnd, $string_add . "\r\n" . $string_fnd, $vbulletin->templatecache['footer']); 

    unset($string_fnd, $string_add); 


how i do the same in vb4 ?

Thanks in Advance
