Page Navigation

[codenut]

One of our users had requested if something like this would be possible for page navigation:

Pages: « < 1  ... 3 4 [5] 6 7  ... 27 > »

and since I didn't see anything that could mod the existing structure I thought I might as for it.

You can do that very easily by modifying the constructPageIndex(); function.

good idea, especially the arrows < >>

well considering my php skills are none existant I will have to wait until some enterprising modder decides to help out

Here's the modified constructPageIndex(); function
Replace the one in Sources/Subs.php

thank you very much that is greatly appreciated and worked like a charm. I'll head over and have a look at the Go to now
