how to add ordering tool in to a customized component

pixeltrace · 27.04.2007, 13:05

hi,

joomla newbie here.
i got this tutorial called daily message from
w3.jlleblanc.com/content/view/9/54/
and the way it works, its exactly what i needed for my thesis project. unfortunately, it doesnt have a ordering/reorder tool so with that, i need to add it. since i cannot read php codes that well yet, i just took all related codes from other components like com_weblinks but i dont know if i was able to do it right.

the first page (view page) dont have any errors, but when i click on the "new" button, this is the error message that i am getting

Code:

Warning: Missing argument 3 for HTML_BrandName::edit() in /var/www/html/memoryworld/administrator/components/com_brandname/admin.brandname.html.php on line 6

Warning: Missing argument 4 for HTML_BrandName::edit() in /var/www/html/memoryworld/administrator/components/com_brandname/admin.brandname.html.php on line 6

Ordering:  
Fatal error: Cannot use object of type BrandName as array in /var/www/html/memoryworld/administrator/components/com_brandname/admin.brandname.html.php on line 19

i have 2 page, admin.brandname.html.php and admin.brandname.php

hope you could help me with this, because i really really need to it fix real soon.
