Auto-Template edits with RegEx

[JamesGunner]

Hello,

I created my product here:

https://vborg.vbsupport.ru/showthrea...hreadid=231363

Now I wanted to add auto-template edits. Since it's multiple line edits I thought of using regex. Now this is the actual part where I'm stuck. After getting plenty of errors, I fixed those but now I'm stuck at the point where it still doesn't seem to replace the cached template but no errors pop up. I searched for a couple of Tutorials for auto-templates but those don't work for me since I have to replace multiple lines. I found the most useful:

Anyways this is my product code:

<plugin active="1">
      <title>Do first template edit</title>
      <hookname>forumdisplay_complete</hookname>
      <phpcode>
        <![CDATA[$templatefind1 = '~<vb:if condition="$show[\'newthreadlink\']">(.+?)id="newthreadlink_top"(.+?)vb:if>~s';
$templaterepl1 = '<vb:if condition="$show[\'newthreadlink\']"><vb:if condition="$foruminfo[\'new_thread_link\']"><a href="{vb:raw foruminfo.new_thread_link}" rel="nofollow" class="newcontent_textcontrol" id="newthreadlink_top"><span>+</span> {vb:rawphrase post_new_thread}</a><vb:else /><a href="newthread.php?{vb:raw session.sessionurl}do=newthread&amp;f={vb:raw foruminfo.forumid}" rel="nofollow" class="newcontent_textcontrol" id="newthreadlink_top"><span>+</span> {vb:rawphrase post_new_thread}</a></vb:if><vb:else />&nbsp;</vb:if>';

$vbulletin->templatecache['FORUMDISPLAY'] = preg_replace ($templatefind1, $templaterepl1, $vbulletin->templatecache['FORUMDISPLAY']);]]>
      </phpcode>
    </plugin>

1. I tried many things also the stuff described in the above named thread, it still didnt work. I hope you guys are able to help me in some way

2. I also couldn't find a way to display the ouput of $vbulletin->templatecache['FORUMDISPLAY']. Is there any standard way?

I just found that RegEx would be the best solution if you guys could suggest any better than that would be appreciated.

Thanks for the help ahead.
