getPage + getResources display message "No Results"

Hi.
I'm using getPage with getResources. It returns all results I need with this code:

[[!getPage? &elementClass=`modSnippet` &element=`getResources` &parents=`8` &showHidden=`1` &tpl=`chkresources` &includeContent=`1`  &includeTVs=`2`  &processTVs=`2` &sortby=`menuindex` &sortdir=`ASC` &limit=`12` &tvPrefix=`` &hideContainers=`1`  &pageLimit=`5`   &pageNavVar=`page.nav`]]

I'm trying to get a message if there is no results. And for some strange reason it does not work. I put this code

&element=`getResources:default="No Results"`

instead of

&element=`getResources`

Thanks

Please highlight your code (snippet tags) and click on the <> icon in the toolbar so we can see the code clearly.

The getPage snippet calls the getResources snippet something like this:

$snipppet = $scriptProperties['element]';
$modx->runsSnippet($snippet);

So, if &element is set to `getResources`, that's the equivalent of this:

$modx->runSnippet('getResources');

In your case, though the &element property is set to `getResources:default="No Results"`, so it's trying to do the equivalent of this:

$modx->runSnippet('getResources:default="No Results"');

There is no snippet with that name, so you get no results.

Thank you. Now I understand. So, my next question would be the following. Is it possible to display the message after there is no results returned from getResources if getResources is used with getPage.

Thanks again

You could try this. I'm not sure if it will work:

[[!getPage:default="No Results"? 
    &elementClass=`modSnippet` 
    &element=`getResources` 
    &parents=`8` 
    &showHidden=`1` 
    &tpl=`chkresources` 
    &includeContent=`1`  
    &includeTVs=`2`  
    &processTVs=`2` 
    &sortby=`menuindex` 
    &sortdir=`ASC` 
    &limit=`12` 
    &tvPrefix=`` 
    &hideContainers=`1`  
    &pageLimit=`5`   
    &pageNavVar=`page.nav`
]]

If it doesn't this might:

[[!+MyResults:default="NoResults"]]

[[!getPage:default="No Results"? 
    &toPlaceholder=`MyResults`
    &elementClass=`modSnippet` 
    &element=`getResources` 
    &parents=`8` 
    &showHidden=`1` 
    &tpl=`chkresources` 
    &includeContent=`1`  
    &includeTVs=`2`  
    &processTVs=`2` 
    &sortby=`menuindex` 
    &sortdir=`ASC` 
    &limit=`12` 
    &tvPrefix=`` 
    &hideContainers=`1`  
    &pageLimit=`5`   
    &pageNavVar=`page.nav`
]]

If neither of those works, see if you can post the actual code returned from getPage when there are no results by wrapping the tag in pre tags.

Thanks a lot!!!

[[!getPage:default=`No Results`? 
&elementClass=`modSnippet` 
&element=`getResources` 
&parents=`8` 
&showHidden=`1` 
&tpl=`chkresources` 
&includeContent=`1` 
&includeTVs=`2`  
&processTVs=`2` 
&sortby=`menuindex` 
&sortdir=`ASC` 
&limit=`12` 
&tvPrefix=`` 
&hideContainers=`1`  
&pageLimit=`5`  
&pageNavVar=`page.nav`]]

Here it is. Works as it should. [ed. note: webpaul64 last edited this post 12 years, 6 months ago.]

I'm glad to hear it. I really didn't think it would be that simple. wink

BTW, it's completely up to you, but I find that formatting my snippet calls as in my post above makes it much easier to maintain them. MODX parses them fine that way.

Absolutely! I'll do it next time. Just a simple addition. Instead of

:default=`No Results`

better to use a chunk

:default=`[[$chkempty]]`

The best solutions are the simple ones.
