PrevJumpNext for 2.1.1

I had PrevJumpNext working but have now updated my site to 2.1.1 and it has stopped working.

A quick look and it seems getActiveChildren has been depreciated and removed and thats causing the problem.

I have read I can replace getActiveChildren with getCollection but how do I get it to return the same as getActiveChildren so the snippet will work again?

I have added

$children = modX->getCollection(’modResource’, $criteria);

but don’t know how to get the $criteria setup to create the required output.

Any help much appreciated.

thanks

From the original GetActiveChildren :-



There may be a better way to do this now in the 2.1 API.

Thanks for the quick response.

Is that the actual code from getactivechildren, or have you modified it to work.

I have tried implementing it by adding it to the prevjumpnext snippet but just get a blank page.

am I missing something?

Cheers

Its from the code base, so you need to set the $id, in the line ’sc.parent => $id’ substitute the id passed in the snippet for $id. I’ve not looked at the snippet itself but you should be able to blend this into it.

Hi,

I have replaced

$children = $modx->getActiveChildren($startID, $sortBy, $sortHow, $fields);

with


$fields=’id, pagetitle, description, parent, alias, menutitle, class_key, context_key’;
$columns = explode(’,’, $fields);
foreach ($columns as $colKey => $column) $columns[$colKey] = trim($column);

$criteria = $this->newQuery(’modResource’);
$criteria->setClassAlias(’sc’);
$criteria->select(’id’);
$criteria->select($columns);
$criteria->where(array(
’sc.parent’ => $startID,
’sc.published’ => ’1’,
’sc.deleted’ => ’0’
));

$children = $modx->getCollection(’modResource’,$criteria);


But this just gives me a blank white page

If I comment out

//$children = $modx->getCollection(’modResource’,$criteria);

the page will display but the prevjumpnext function outputs no links

am I missing something, I have followed it through and it all seems to make sense

Cheers

The ’$criteria = $this-’ should be $modx, not $this, try that.

Hi, Thanks for the suggestion,

have updated the $this to $modx but I am still getting a blank page when I remove the // from the line below

//$children = $modx->getCollection(’modResource’,$criteria);

is there a problem with getCollection, how would I check this?

Many Thanks

I use selfLink instead of PrevJumpNext.
It has been developed very simple but I asked Bruno17 to extend it so this came out:

<?php
/**
* selfLink
* To navigate up, next or previous from the current resource or from the given resource
*
* Options
*
* id - The id where the direction is from. Default the current resource id
* direction - To create a link in the direction up, previous or next
* tpl - The chunkname wich is used for the view of the link
* linktext - The text used for the link instead of the pagetitle
*
* Example usage:
* [[!selfLink? &id=`[[*id]]` &direction=`next` &tpl=`commonName`]]
*

$resource = $modx->getOption(’id’, $scriptProperties, $modx->resource->get(’id’));
$direction = $modx->getOption(’direction’, $scriptProperties, false);
$tpl = $modx->getOption(’tpl’, $scriptProperties, false);
$linktxt = $modx->getOption(’linktext’, $scriptProperties, false);

if ($res = $modx->getObject(’modResource’, $resource)) {
$menuindex = $res->get(’menuindex’);
$parentid = $res->get(’parent’);
$c = $modx->newQuery(’modResource’);
$c->limit(1);

switch ($direction) {

case ’up’:

$c->where(array(’id’ => $parentid));
break;

// parse chunk
$chunk = $modx->getObject(’modChunk’, array(’name’ => $tpl));

if (!$chunk) {

$useChunk = ’<a href="[[~[[+id]]]]">[[+menutitle]]</a>’;
$chunk = $modx->newObject(’modChunk’);
$chunk->setCacheable(false);

return $chunk->process($placeholders, $useChunk);
}

return $chunk->process($placeholders);
