Variable Substitution

[ConX]

Reported on dokuwiki.org by

It would be great to be able to insert other data as well, eg dates, username etc

eg I have a button that inserts

<todo startdate:yyyy-mm-dd @user>//my text here//</todo>

I'd like to be able to have custom button fill in information such as the date, time and username (or any other info calculated from that eg:

<todo startdate:@Date@ due:@date@+10 @@user@>Update AVG boot disk</todo>
would show as

<todo startdate:2015-02-25 due:2105-03-07 @Chris>Update AVG boot disk</todo>
To achieve the above date substitutions edit your action.php file in the plugin folder to include these additional lines:

    protected function loadCBData() {
        $json = new JSON(JSON_LOOSE_TYPE);
        $file = @[file_get_contents](http://www.php.net/file_get_contents)(DOKU_PLUGIN . "custombuttons/config.json");
        if(!$file) return false;
 
/** Start of new lines */
        $file = [str_replace](http://www.php.net/str_replace)('@@TODAY@@',[date](http://www.php.net/date)("Y-m-d"),$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@USER@@',$client,$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@ONEWEEK@@',[date](http://www.php.net/date)("Y-m-d",[strtotime](http://www.php.net/strtotime)('+7 days')),$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@TWOWEEKS@@',[date](http://www.php.net/date)("Y-m-d",[strtotime](http://www.php.net/strtotime)('+14 days')),$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@THREEWEEKS@@',[date](http://www.php.net/date)("Y-m-d",[strtotime](http://www.php.net/strtotime)('+21 days')),$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@FOURWEEKS@@' ,[date](http://www.php.net/date)("Y-m-d",[strtotime](http://www.php.net/strtotime)('+28 days')),$file);
        $file = [str_replace](http://www.php.net/str_replace)('@@ONEMONTH@@',[date](http://www.php.net/date)("Y-m-d",[strtotime](http://www.php.net/strtotime)('+30 days')),$file);
/** End of new lines */
 
        return $json->decode($file);
    }

I'm still working on getting the username substituted in… If I'd known it was this simple I'd have done it ages ago. The placeholders to put in your button text are @@today@@, @@oneweek@@ etc. Hopefully, it's obvious enough to make your own tweaks.
