Block assign doesn't break, but doesn't work?

[rudiedirkx]

In the child template:

{block content}
  Content with lots of html here
{/block}

In the parent template:

{block name=content assign=content}{/block}
{$content|strlen}

But $content is empty. assign seems to be a valid parameter, but it's not used?

It is supported, but probably not in the way you expected it to be. The child block completely overwrites the block with the same name in the parent. So in your example, the assign=content part is never executed. If you set assign=content on the child block, it does work though:

038_parent.pl

{block name=content}{/block}Captured content is: {$content}

038_child.tpl

{extends file='038_parent.tpl'}
{block name=content assign=content}Content with lots of html here{/block}

result

Captured content is: Content with lots of html here

But I can't have the assignment depend on the child template.... The parent template decides what to do with the block output. Is my case not possible? In a different way, not with assign.

In Twig you can 'call' a block from the parent in 2 ways:

1. {% block content %}{% endblock %} if you just want to print/stream it inline, like a Smarty block.
2. {% set content = block('content')|trim %} if you want to do something with it, like check if it's empty after trimming the output, or show it twice, etc.

Does Smarty have 2.?

Blocks can be nested, or you can nest the block in a {capture}. SimonOp 6 feb. 2023 om 03:06 heeft Rudie Dirkx @.***> het volgende geschreven: But I can't have the assignment depend on the child template....
