If you need to create a simple Infocenter (An endless slideshow of pages), you can do it with this little TypoScript snippet.

The TypoScript will display all subpages to a given ID in an endless loop, by adding a META refresh tag to every page, pointing to the next in line.

When the last subpage is displayed, it will start over with the 1st subpage again.

There's also an additional TypoScript snippet (lib.pagecount) that can be used if you want to display a pagecounter on the pages.

-- constants Start --
# number of seconds befoore the next page is displayed
refreshdelay = 5
# ID of page which subpages should be displayed 
slideroot = 41
-- Constants End --

-- Setup Start --
# Snippet for Infocenter
lib.refresh = COA
lib.refresh {
  10 = CONTENT
  10.table = pages
  10.select {
    pidInList = {$slideroot}
    orderBy = sorting
    andWhere.dataWrap = sorting>{field:sorting}
    max = 1
  }
  10.renderObj = COA
  10.renderObj {
    10 = TEXT
    10.typolink.parameter.field = uid
    10.typolink.returnLast = url
    wrap = {$refreshdelay};|
  }
}
page.meta.refresh.cObject < lib.refresh
page.meta.refresh.cObject.10.select.andWhere >
page.meta.refresh.override.cObject < lib.refresh

# Snippet for displaying pagecounter
lib.pagecount = COA
lib.pagecount {
  10 = TEXT
  10.numRows.table = pages
  10.numRows.select.pidInList = {$slideroot}
  10.numRows.select.orderBy = sorting
  10.numRows.select.andWhere.dataWrap = sorting<={page:sorting}
  10.wrap = |/
   
  20 = TEXT
  20.numRows.table = pages
  20.numRows.select.pidInList = {$slideroot}
  20.numRows.select.orderBy = sorting
}

UPDATE!

I have noticed a problem with using META refresh to load the next page. If the connection drops out, the META refresh will show an error msg. and stop.

A solution to that problem is to make the refresh using JavaScript/AJAX. An example/tutorial can be found here:
