[Solved] Re-define template in $this->partials($this->config() ... possible?

[rowild]

I would like to override the filter tree components. In a first step, the templates are overridden in the Typoscript Configuration field of the "aimeos__catalog-tree" extension:

Code: Select all

client.html.catalog.filter.tree.standard.template-body = catalog/filter/tree-body-startpage
client.html.catalog.filter.partials.tree = catalog/filter/tree-partial-startpage

That works fine. Now I would like to use a different template for all categories of level 1. I thought I could do that by manipulating this art of the code:

Code: Select all

 // tree-partial-startpage.php, around line 125ff
 
<?php if( count( $item->getChildren() ) > 0 ) : ?>
	<?= $this->partial(
		$this->config( 
			'client/html/catalog/filter/partials/tree', 
			'catalog/filter/tree-partial-startpage-categories' ),  // <== use new partial in levels > 0?
		[
			'nodes' => $item->getChildren(),
			'path' => $this->get( 'path', map() ),
			'level' => $this->get( 'level', 0 ) + 1,
			'params' => $this->get( 'params', [] )
		]
	); ?>
<?php endif; ?>

pointing to a different template within the

Code: Select all

`$this->config($this->partial-> ...

section.

Unfortunately, this does not work.
What would be the proper way to do that? If it is possible at all?

Thank you!

What exactly does not work? Is the template not loaded?

The same template that is defined in the Typoscript Configuration is displayed again. Not the new one that is refered to in the loop.

I have troubles understanding the "$this->partials($this->config" logic.

E.g., when I take this snippet that is responsible for displaying the media:

Code: Select all

<?= '-->'
. $this->partial(
	$this->config( 
		'client/html/common/partials/media', 
		'common/partials/media-standard' 
	),
	array( 'item' => $mediaItem, 'boxAttributes' => array( 'class' => 'media-item' ) )
) . '<!--'; ?>

and I assign it a non existing template:

Code: Select all

'common/partials/this-template-does-not-exist'
 

then an error is thrown in the FE (one of those "An unrecovereable error...").

But when I assign a wrong template in the loop section of the tree filter:

Code: Select all

<?php if( count( $item->getChildren() ) > 0 ) : ?>
	<?= $this->partial(
		$this->config( 
			'client/html/catalog/filter/partials/tree', 
			'catalog/filter/template-does-not-exist' ),  // <== wrong template here
		[

nothing spectacular happens, no error, everything is displayed using the template assigned via TS.

Why does the second scenario not throw an error?

[aimeos]

You've configured "client/html/catalog/filter/partials/tree" elsewhere so the default value in the second parameter isn't used.

I can confirm that once a template override is done in TypoScript, a "default" is defined. And that means that the respective php functions won't reassign a new template anymore.

In my case, to stay flexible, it seems to be better to override templates directly in the php `$hits->partial($this->config ...` functions.
