Search and replacing issue

[ShadowMage]

Making a plugin for a site and when I try to do the search and replace for activate/deactivate it completely screws over and doesn't work as it should.


The code is:

function gradient_activate()
{
    include MYBB_ROOT."/inc/adminfunctions_templates.php";
    find_replace_templatesets("usercp_nav_misc", '#'.preg_quote('<tr><td class="trow1 smalltext"><a href="{$profile_link}" class="usercp_nav_item usercp_nav_viewprofile">{$lang->ucp_nav_view_profile}</a></td></tr>').'#', '<tr><td class="trow1 smalltext"><a href="{$profile_link}" class="usercp_nav_item usercp_nav_viewprofile">{$lang->ucp_nav_view_profile}</a></td></tr><tr><td class="trow1 smalltext"><a href="page.php" class="usercp_nav_item usercp_nav_usergroups">The link</a></td></tr>');
}

function gradient_deactivate()
{
    include MYBB_ROOT."/inc/adminfunctions_templates.php";
    find_replace_templatesets("usercp_nav_misc", '#'.preg_replace('<tr><td class="trow1 smalltext"><a href="{$profile_link}" class="usercp_nav_item usercp_nav_viewprofile">{$lang->ucp_nav_view_profile}</a></td></tr><tr><td class="trow1 smalltext"><a href="page.php" class="usercp_nav_item usercp_nav_usergroups">The link</a></td></tr>').'#','<tr><td class="trow1 smalltext"><a href="{$profile_link}" class="usercp_nav_item usercp_nav_viewprofile">{$lang->ucp_nav_view_profile}</a></td></tr>'); 
}
