getPage: Property &totalVar and Output filter

Hi all,

this getPage call

[[!getPage@fooPropertySet? 
	&element=`migxLoopCollection` 
	&packageName=`foo` 
	&classname=`Foo` 
	&tpl=`theRowTpl`
	&limit=`20`
	&totalVar=`itemsTotal`
]]

allows to output the total number of items using the tag [[+itemsTotal]].
But in case there are no items found, instead of 0 the output is empty.

Trying the output filter

[[+itemsTotal:is=``:then=`0`]]

I always get the output 0, whatever be the value.

What am I missing?

I think it has to do with the parsing-order of the uncached getPage - call and when the output-filter is parsed.

You might try another uncached snippet:

[[!getIntPlaceholder? &placeholder=`itemsTotal`]]

return (int) $modx->getPlaceholder($placeholder);

does this work?

No, this always results in 0, too.
Omitting the type casting (int), the result is empty (whatever the number of items found).

was trying this:

[[!getPage?
&element=`migxLoopCollection`
&classname=`modResource`
&limit=`20`
&totalVar=`itemsTotal`
&tpl=`@CODE:[[+pagetitle]]<br>`
&where=`{"parent":"99999"}`
]]

[[+itemsTotal]]

and get as result 0, which is correct.

without the &where, I get the correct number of resources, too.

I should have mentioned that my &classname=`Foo` refers to a CMP table, so it's not modResource.

This all worked very well, I just wanted to replace the empty result of [[+itemsTotal]] by the number 0, in case.

Testing around, I removed the @fooPropertySet reference from the getPage call, resulting in the snippet not being rendered at all.
(That fooPropertySet is nothing special, just a copy of the default property set for modifications in the future.) Why does this happen?

And now a real disaster: putting it back (exactly how it was before), nothing changes: getPage is not rendered anymore!
What the hell is going on here?

modResource or another table. This shouldn't make any difference.
I get allways the number 0, if no results.

Are you sure, you have the snippet-call exactly as it was before and you didn't change anything else?

To repair my disaster I had to restore the database from a backup.

Now only when I omit the property &totalVar=`itemsTotal` from the getPage call, I get back the rendered output like before.

Including this property to the call however results in the following message:

Fatal error: Call to undefined function getpage_buildControls() in /www/htdocs/########/#####.de/core/cache/includes/elements/modsnippet/112.include.cache.php on line 88

This is the code around line 88:

    if (empty($properties[$properties['totalVar']]) || empty($properties['actualLimit']) || $properties[$properties['totalVar']] <= $properties['actualLimit'] || ($properties['page'] == 1 && $properties[$properties['totalVar']] <= $properties['pageOneLimit'])) {
        $properties['page'] = 1;
    } else {
        $pageNav = getpage_buildControls($modx, $properties);
        $properties[$properties['pageNavVar']] = $modx->newObject('modChunk')->process(array_merge($properties, $pageNav), $properties['pageNavOuterTpl']);
        if ($properties['page'] > 1) {
            $qs[$properties['pageVarKey']] = $properties['page'];
        }
    }

So why this function is undefined?

Sounds like there is more corrupted than just the database.
Does this file exist?

Thank you, Bruno - indeed the whole getPage folder was missing in core/components/. I should have restored the files from the backup, too.

But there remains the mystery how it could disappear.
The only action I performed these days was deleting the Articles Extra. Is it imaginable that this was deleting getPage too?
(If so, there should be a warning of such an unwanted side effect.)

I think getPage is included within articles.
So, if you delete the articles-extra, this might also delete the extras which are included with the articles-package.
