I get no error when I use my item, but I get this error if I go to it directly:


Fatal error: Class item_firescroll: Cannot inherit from undefined class itemtemplate in

Here it is:

Code: [Select]

You're not meant to go to the item directly, as that will always happen (indeed, I should have implemented better error handling in the items).

Adding something like this just above the 'class item_FireScroll' line would prevent the ugly message (just make sure that the file is indeed called 'FireScroll.php':

Code: [Select]

if (eregi("FireScroll.php",$_SERVER['PHP_SELF'])) die("You can't run this directly!");
Basically, this checks if you're running FireScroll.php, and if you are, show an error. When you're using the item, the user is actually accessing index.php, so the error won't be displayed.

Lol, when I meant I get no error when I use the item, I also meant to put that nothing happens.

It's supposed to return a line from fireattacks.txt, but it does not. Help pls?

Edit:

I changed it by using an array instead of making it read from a file. Longer, but it works so meh.

Now I just need it to send that same message to both the user and Admin :X

hi

how can you use more than four function getAddInput() ? and why does the limitation exist?

awesome tutorial btw Basil Beard

cheers

[Daniel15]

The limitation is because of how I've coded the getAddInput() values - They're stored in 4 seperate database fields in the smf_shop_items table (hence the limitation). I'll try to work on storing these in a better format, which should allow an unlimited number of values
