Code:
return getmyurl("storycattitle", $var1, $var2, $var3); After line 683:
Code:
If ($x == "storycattitle") {return my_pligg_base."/" . $var1 . "/" .$var2 ."/";} and replace by:
Code:
If ($x == "storycattitle") {return my_pligg_base."/" . $var1 . "/" . $var3 . "_" .$var2 ."/";} It's all ! But don't forget to put the redirection line in your .htaccess, like this (before this line: ##### URL Method 2 End #####):
Code:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/([0-9]+)_([^/]+)/?$ story.php?title=$3&category=$1 [L]
