Why does PHx evaluate the "else" clause when it's false?

If I'm understanding you, you don't need a switch. Just something like this:

$id = $modx->resource->get('id');
$parent = $modx->resource->get('parent');

if (($id == 1) || ($parent == 1)) {
    return '[[Ditto . . .]]';
}
return '';

Oh, Oh. I just realized that if it's Ditto, you're probably using Evolution. You could leave out the first line, but I can't remember how to get the parent ID in Evo. It might be set, if so, you can just delete the first two lines.

This should work for Evolution:

$id = $modx->documentObject['id'];
$parent = $modx->documentObject['parent'];

$output ='';
if( $id == 1 || $parent == 1 ){
    $output .='[[Ditto . . .]]';
}

return $output;

Thanks guys, I haven't tried ditto directly into the snippet.

Evolution user, I like the back-end speed and simplicity

Or you could runSnippet('Ditto', array(...)) and return it; that would save further processing in the next pass of the parser.

I'm busy with an other project, and need to be able to say;

if id=1 then load chunk main-home
if id=4 then load chunk main-gallery
else = chunk main-standard

But main-home has also some ditto call into it, this doesn't work.

So I can probably use a phx:modifier which allows dittocalls into it?!
https://github.com/Jako/PHx-Modifier

But how do I use it?

I think I did do one some time ago but can't remember how I did it and on what project.

Documentation says:

[+string:switch=`xx:{{Chunk}}|yy:[*DocVar*]|default:[+TemplateVar+]+]

I have paste the snippet code and called the snippet switch but doesn't work:

[+string:switch=`1:{{main-home}}|4:{{main-gallery}}|default:{{main-standard}}+]

Anyone can point me in right direction?
Can't load a snippet into a snippet

####EDIT####

I guess it does work when I call my Ditto uncached!
For peoples who might want to use this:

My call:

[!main-switch?
&parent_ids=`1,4`
&chunk_names=`main-home,main-pizza`
&def_chunk_name=`main-default`
!]

My snippet:

<?php
// set the default ids of the top level parent containers
$default_parent_ids = array();
 
// set the default names of the chunks to display
// based on the same order as the $parent_ids
$default_chunk_names = array();
 
// set the overall default chunk name
$default_chunk_name = isset($def_chunk_name) ? $def_chunk_name : '';
 
// ===== end setup ===== //
 
 
$parent_ids = isset($parent_ids) ? explode(',',$parent_ids) : $default_parent_ids;
$chunk_names = isset($chunk_names) ? explode(',',$chunk_names) : $default_chunk_names;
 
if(count($parent_ids) > 0 && count($chunk_names) > 0){
 
    $uparent = $modx->runSnippet('UltimateParent');
    $check_array = array($modx->documentObject['id'],$modx->documentObject['parent'],$uparent);
 
    for($x=0; $x < count($parent_ids); $x++){
        if(in_array($parent_ids[$x],$check_array)){
            $print_chunk = $chunk_names[$x];
        }
    }
     
    // if $print_chunk is empty set to overall default
    if($print_chunk ==''){
        $print_chunk = $default_chunk_name;
    }
     
}
 
return $modx->getChunk($print_chunk);
?>

Main-home chunk has this dittocall:

[[Ditto? 
&parents=`9`
&total=`3`
&showPublishedOnly=`1` 
&orderBy=`menuindex ASC` 
&noResults=`No news..` 
&tpl=`news-ditto`
]]
