Modx Chunk Ifs

zzfkelvin — Jun 15, 2018, 06:34 AM

Is it possible to add something like "else if" in Chunks?
[[*id:eq=`resource id`:or:eq=`resource 2 id`:then=``:else=``]]

Don't put all that code on every page -- that's crazy. Think about what happens when you need to change a script.

Put the scripts in three chunks named Chunk28, Chunk23-24-39, and DefaultChunk. Then do this.

Put this where you want the script:

[[!AddScript]]

Create a snippet called AddScript with this code:

/* AddScript snippet */
$chunkName = '';

$template = $modx->resource->get('template');

switch($template) {
   case 28: 
     $chunkName = 'Chunk28';
     break;

   case 23:
   case 24:
   case 37:
     $chunkName = 'Chunk23-24-37';
     break;
   
   default:
     $chunkName = 'DefaultChunk';
     break;
}

return $modx->getChunk($chunkName);

It will be much faster and infinitely easier to maintain.

Stuff like this is infinitely faster and more reliable in PHP, and not very complicated:
(I'm guessing at what you want -- feel free to clarify)
[[!SomeSnippet]]
/* SomeSnippet code */

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

if ($docId == 12 || $docId == 22) {
   $output = 'something';
} else {
   $output = 'something else';
}

return $output;

I'm trying to add some schema codes into our website, I created a chunk named XJTLU_Schema, and call this chunk inside site.head chunk.
In this XJTLU_schema chunk, I set some condition to add schema codes according to different page template, for example,

[[*template:eq=`28`:then=`

`:else=``]]

[[*template:eq=`23`:or:is=`24`:or:is=`37`:then=`

`:else=``]]

I only need to identify some key templates with different types, such as person, organization, event.....But for the other pages, I don't want to type the template ID one by one, I think if it could has some code like "else" to apply one all the other pages.

Yeah but in chunks the placeholder would be a [[+id]] instead of [[*id]]

how should I write the else if code?

[[*id:eq=`resource id`:or:eq=`resource 2 id`:then=`

`:elseif:*id:eq=`b`:then=`

`]]

is it?
