[pmwiki-users] Insert text only once

[Richard Haven]

I am writing some PHP rules (scripts) files.
 
In one, I have some javascript that should exist only once per page in
addition to another tag. How do I detect that the user has use (:tag
blah:) more than once so I can omit emitting the singleton content?
 
I am trying 
 
SDV('$Flag']), 0); 

global Flag;

if ($Flag == 0){

    $codeSnippet .= "<script type=\"text/javascript\"
src=\https://domain.com/init.js <https://domain.com/init.js>
\"></script>";

    $Flag = 0;

}

Am I on the right track ?

 

Thanks
