next/prev more next and prev. help reques

[dheaven69]

function setPointer(&$array, $set_key) {
reset($array);
while ($set_key != key($array)) {
	next($array);
}
}

 

the function i use for output is a little more complicated

 

function menu($item = THIS_CAT) {
$menuf = file(MENU);
$menuf = array_map('trim', $menuf);
$key = array_search($item, $menuf);
setPointer($menuf, $key);
$prev = prev($menuf);
setPointer($menuf, $key);
$next = next($menuf);
if($prev !== false) {
	$nav = "\n".'$prev';
}
if($next !== false) {
	$nav .= "\n".'$next';
}

 

well i can't make it show prev<-prev<-prev | next->next->next

                                  -3      -2      -1      1      2        3

what exactly is the problem?

[dheaven69]

well this code works but i can't make it output more then this

[boo_lolly]

you can't make it output more than what?

 

and what are you trying to make it output? and what is the desired effect of each of the links?

 

help me help you.

ah sorry for the poor explanation this are my first days of php

 

this was build for a simple navigational menu that shows the previous and the next link.

what i wish from this is to show the previous before previous ..... and the next after next .... links (more the n 2 links)

ok, there are hundreds of ways to do what you want. first, it is called 'pagination'. go to www.google.com and search for tutorials. if you don't understand it after that, then come to the forums.
