Questions and syntax LATTE (Template Engine by Nette)

[sebibu]

I really love LATTE (Template Engine by Nette) but here and there I still have problems with the syntax.

I'm using RockPageBuilder by @bernhard and try to output the html for this module:
https://processwire.com/modules/fieldtype-leaflet-map-marker/

In PHP this would be:

<?php echo $map->render($page, 'YOUR MARKER FIELD'); ?>

And in LATTE? 😆 I tried this variants and more:

{$map->render($page, 'map')}
{$map->render($page, 'block->map')}
{$map->render($page, $block->map)}

Getting: Call to a member function render() on null in block #1158 (rockpagebuilderblock-map)

Maybe this topic can be a collection point for smaller Latte syntax questions.

This

<?php echo $map->render($page, 'YOUR MARKER FIELD'); ?>

would be this

{$map->render($page, 'YOUR MARKER FIELD')}

Your error message means, that $map is NULL. That means $map is not available in your latte file for whatever reason. That means you are not struggling with latte syntax, you are struggling with PHP 😉 😛 

You can easily debug this via TracyDebugger:

{bd($map)}
{bd($page)}

To help you with your specific problem I'd need more info in where you are trying to use this markup...

It looks like you need to make $map available in your Latte file first. Then, as Bernhad has said, you could write in your Latte file

{$map->render($page, 'YOUR MARKER FIELD')}

With https://processwire.com/modules/template-engine-latte/ you would write something like the following in your PHP template file (or ready.php):

$view->set('map', $map);

It might vary depending on which modules you use exactly in your project.

RockFrontend / Latte doesn't provide this syntax as far as I know. What are you referring to?

Ah sorry, now I see $map should be a map marker object. The docs there state this:

<?php $map = wire('modules')->get('MarkupLeafletMap'); ?>

Which you could do in latte like this:

{var $map = wire('modules')->get('MarkupLeafletMap')}

Updated the post to be clear it's an example and varies depending on which modules are used.
