Hi,

To solve my previous question i just need to add the creation and the returns (that's what I can't figure out how to do) in the pdoNeighbors snippet;

This snippets get exactly what I need ($prev and $next ) that contains early in its code the values of the previous and next sibling pages ID
I really need to get those ids returned as placeholders like +prev_id and +next_id for instance.

Can someone tell me how to do this, as I'wont desperately never be enough PHP friendly...

Thanks a lot.

I think, this is what you want:

<?php
//[[getNext? &field=`longtitle` &menueindex=`[[+menuindex]]` &parent=`[[+parent]]`]]

$field = $modx->getOption('field',$scriptProperties,'pagetitle');

$c = $modx->newQuery('modResource');
$c->where(array('parent'=>$parent,'menuindex:>'=>$menuindex));
$c->sortby('menuindex');
$c->limit(1);

$output = '';

if ($object = $modx->getObject('modResource',$c)){
    $output = $object->get($field); 
}

return $output;

called like that should give you the longtitle of the next resource in the same parent-container:

[[getNext? &field=`longtitle` &menueindex=`[[+menuindex]]` &parent=`[[+parent]]`]]

-------------------------------

you can buy me a beer, if you like MIGX

hum..Thanks a lot!
it's almost this, But I should have to give it only the current id of a page to find the id of its next (or prev) .

So I tried to change your code into this..and of course I get a blank page when called.

<?php
//[[getNext? &field=`id`
 &menueindex=`[[+menuindex]]` &parent=`[[+parent]]`]]

$field = $modx->getOption('field',$scriptProperties,'pagetitle');

$c = $modx->newQuery('modResource');
$c->where(array('parent'=>$parent,'menuindex:>'=>$menuindex));
$c->sortby('menuindex');
$c->limit(1);

$output = '';

if ($object = $modx->getObject('modResource',$c)){
    $output = $object->get($field); 
}

return $output;

you don't need to change the snippet - code.

Try to call it like that:

[[getNext? &field=`id` &menueindex=`[[+menuindex]]` &parent=`[[+parent]]`]]

Yes but there was some typo 'menueindex' -> menuindex
however blank page

it's alaways called inside the PDO Resource tpl

where I have the current id inside [[!+id]]

[[!+id]]- <a class="down-arrow-btn" href="[[!getNext? &field=`[[!+id]]` &menuindex=`[[!+menuindex]]` &parent=`[[!+parent]]`]]"><i class="glyphicon glyphicon-chevron-down"></i> </a>

Even if I test with hardcoded value (id 9 and menuindex 10 for examples, no way..blank page..

Once the snippet code coorected from some typo. no more blank page BUT no output from the snippet it returns nothing [ed. note: elz064 last edited this post 12 years ago.]

with this in your code

<?php
//[[getNext? &field=`id`
 &menueindex=`[[+menuindex]]` &parent=`[[+parent]]`]]

you will get a blank page, of course!

in fact, I'm trying to modify the pdoNeighbors to make it output 2 nex PL.
But I'm really not PHP friendly and I just can't understand the array mess this snippet deals with:

After line 65 it displays in the log all the wanted ids I'd like to become place holders

$pdoFetch->addTime('Found ids of neighbors: ' . implode(',', $ids));

I'm pretty sure is a piece of cake to genate +prev_id and +next_id from this start ..?

I found a solution but this don't works if used in the template &tplNext (or &tplPrev).

Into the pdoResource tpl pdoNeighbors is called and

inside this tpl :

[[!pdoNeighbors? &id=`[[!+id]]` &tplWrapper=`PDON-tpl` &tplNext=`@INLINE ` &showLog=`0`]]

and
$PDON-tpl:

<p class="text-center la_suite pdon[[!+id]]">
<a class="down-arrow-btn" href="#[[!pdoField?
    &id=`[[!+neighbor_next_id]]`
    &field=`pagetitle`
]]"><i class="glyphicon glyphicon-chevron-down"></i> </a>
</p>

here's where I hacked the pdoNeihbors snippet :

$ids = array_merge($prev, $next, array($resource->parent));

        for($i=0;$i<count($next); $i++) { 
		//elz  ajout d'un placeholder contenant l'id de la page next. Ce PL n'est vu que dans le &tplWrapper (?)
		$neighbor_next_id = $next[$i];
        //echo "(l'élément next[$i] est  $neighbor_next_id )"; 
		$modx->setPlaceholder('neighbor_next_id', $neighbor_next_id);
		//
        } 
$pdoFetch->addTime('Found ids of neighbors: ' . implode(',', $ids));
