getPage: Property &totalVar and Output filter

ottogal — Apr 14, 2015, 02:52 PM

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'm having this same problem every time there are no elements for the totalVar to count it doesn't output anything and none of the solutions that were put forth have worked

Tried this:

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

The output is, in any case, the same as for

[[+itemsTotal]]

I tried various snippets similar to yours in Reply #2, to no avail.
For $modx->getPlaceholder($placeholder) I always get an empty string.
It seems that the &totalVar property is not handled like other properties.

there must be something else wrong, because

xPDO::getCount(), which is used internally, does allways return an integer, not an empty string.

you can try to change the &totalVar to something different

you can try, if you get something with:

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

(perhaps the value is 0, but gets removed somehow)

Tried it: The output is empty, not 0.

this is strange, because I get 0, if there are no results.
Can you test, what you get with that, what I posted earlier?

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

Thanks again. Glad I have back getPage, but my original question remains open:

There's a &where property too in my call, working well. In case there are no items matching the criteria,
the output of [[+itemsTotal]] is empty, not 0.
Type casting did not help, and Output filters are not working.
What else could I try?

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.

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.)
