Hi guys,

I want to use a snippet that will return a previous and a next link on a page.
these are defined by the menuindex
is there a way to get the menuindex from the current document using the api's?
i couldn't find this

maybe there already is someone who wrote a snippet like this?

[vampke]

okay, i found out how to:

this is the snippet i wrote. I think it could use some tweaking though, i'm manually setting the parent id, where i'm sure i can get it as well using the api's, can anyone gimme any pointers?

this is what i have so far:

// usage: [[prevnext]] 

/* define these lines in the site's css-file and adapt where necessary:
   .prev{
   font-size: 8pt;
   text-align:left;
   float:left;
   padding: 0 0 20px 0;
   }

   .next{
   font-size: 8pt;
   text-align:right;
   padding: 0 0 20px 0;
   }
*/

//define menuindex current page
  $currentid = $etomite->documentIdentifier;
  $fields = "menuindex";
  $doc = $etomite->getDocument($currentid, $fields);
$menuindex = $doc['menuindex'];

$id=140; //parent page - it should be possible to get this automatically

$children = $etomite->getActiveChildren($id); 
$menu = "<div class=\"prevnext\">"; 
$childrenCount = count($children);

for($x=0; $x<$childrenCount; $x++) {

  $childid = $children[$x]['id'];

//define menuindex for sibling
  $fields = "menuindex";
  $doc = $etomite->getDocument($childid , $fields);
  $siblingindex = $doc['menuindex'];

  if ($siblingindex == ($menuindex-1)) {
		  $menu .= "<div class=\"prev\"><a href='[~".$children[$x]['id']."~]' title='".$children[$x]['longtitle']."'><<&nbsp;".$children[$x]['pagetitle']."</a></div> ";
  }

  if ($siblingindex == ($menuindex+1)) {
		  $menu .= "<div class=\"next\"><a href='[~".$children[$x]['id']."~]' title='".$children[$x]['longtitle']."'>".$children[$x]['pagetitle']."&nbsp;>></a></div> ";
  }

}

$menu .= "</div>";

return $menu;

If the rest is correct, you should be able to do this:

$id=$currentid;

$id=$etomite->getParent($currentid, $active=1, $fields='id');

$children = $etomite->getActiveChildren($id['id']);

[EDITED] to add the array $id['id'] to correctly retrieve the parent id[/EDIT]

Nice work vampke, thanks.

I also had to add this before the getActiveChildren in case the current document does not have a parent to stop an error if this is placed in a template.

if($parent['id']==""){ return;}

I've implemented it on my etomite site here, thanks again.

[vampke]

$id=$etomite->getParent($currentid, $active=1, $fields='id');

$children = $etomite->getActiveChildren($id['id']);

Nice work vampke, thanks.

thanks for your help, i'm glad you like my snippet
care to explain what the difference is between my

$children = $etomite->getActiveChildren($id);

and your

$children = $etomite->getActiveChildren($id['id']);

if I add you code

if($parent['id']==""){ return;}

it always returns nothing, shouldn't it be

if($id==""){ return;}

?

[vampke]

I added some more functionality to this.
The first version would only show a link if the previous page had a menu index of 1 less or the next page had a menu index of 1 more than the current page.
This version will generate previous and next links even if difference between the current page's and the previous or next page's menu index is more than 1

// [[prevnext2]]

//define menuindex current page
  $currentid = $etomite->documentIdentifier;
  $fields = "menuindex";
  $doc = $etomite->getDocument($currentid, $fields);
$menuindex = $doc['menuindex'];

$id=$etomite->getParent($currentid, $active=1, $fields='id'); //thank you Chris D. !

if($id==""){ return;}
$children = $etomite->getActiveChildren($id['id']);

$menu = "<div class=\"prevnext\">";
$childrenCount = count($children);

$next=false; //we need to set a boolean in order to know when to generate the "next" link
$pastFirst=false; //we do not need a previous link on the very first page
$quitLoop=false;
$x=0;

while ($quitloop==false && $x<$childrenCount) {

  $childid = $children[$x]['id'];

//define menuindex for sibling
  $fields = "menuindex";
  $doc = $etomite->getDocument($childid , $fields);
  $siblingindex = $doc['menuindex'];

if ($next) {
		  $menu .= "<div class=\"next\"><a href='[~".$children[$x]['id']."~]' title='".$children[$x]['longtitle']."'>".$children[$x]['pagetitle']."&nbsp;>></a></div> ";
		  $next=false; //we only need 1 next link, not a link to all the next pages
		  $quitLoop=true; //we can quit the loop now, because we have our next link
  }

if ($siblingindex == $menuindex) {
		  $next=true; //if loop is in menuindex, next loop should generate the "next" link
  }

if ($siblingindex == $menuindex && $pastFirst) {
		  $menu .= "<div class=\"prev\"><a href='[~".$prevId."~]' title='".$prevTitle."'>&nbsp;<<&nbsp;".$prevPageTitle ."</a></div> ";
   }

//next loop should start with settings from previous loop
$prevId = $children[$x]['id'];
$prevTitle = $children[$x]['longtitle'];
$prevPageTitle = $children[$x]['pagetitle'];

$pastFirst=true; //we are past the first page, the next one needs a previous link
$x++;

}

$menu .= "</div>";

return $menu;

btw: if using this snippet, menu indices should be unique, otherwise more then 1 previous or next link will be generated on 1 page.

edited: bug on first page
edited2: used while instead of for loop, no need to continue looping when a next link is generated

Haven't others already created snippets like it??

care to explain what the difference is between my

$children = $etomite->getActiveChildren($id);

and your

$children = $etomite->getActiveChildren($id['id']);

That's because I got the id from getParent which returns an array, therefore you need to put the array key i to read the id.

Also

if($parent['id']==""){ return;}

it always returns nothing, shouldn't it be

if($id==""){ return;}

Whith the change I made, $id was the current page and $parent['id'] is the id of the parent. Therefore, if there is no parent (at the top of the folder) show no links otherwise you would start viewing siblings. I was using $parent, where you were not.

It's a bit of a moot point now though... and depends on what type of functionality you require, it's good for me though. ta.
