Hi,
I’ve looked through the code around how the flag gpRemoveContainerCondition in the $block[‘attrs’] goes about removing a container where there is no post meta, and was looking to filter/extend this in the same way that the filters like generate_dynamic_element_XXX modify the text.
My use case is that I have a Generate Blocks headline displaying the term meta on an element of a taxonomy term page, and I’d like to hide the container it’s in if the term meta isn’t present.
Is there any way to achieve this through a filter of the block that I’ve not noticed?
Thanks,

Hi there,
you could use the core
render_blockfilter to remove the $block_content for example:add_filter( 'render_block', function( $block_content, $block ) { if ( !is_admin() && is_category() && ! empty( $block['attrs']['className'] ) && 'your-custom-class' === $block['attrs']['className'] ) { $block_content = null; } return $block_content; }, 10, 2 );Hi David,
Thanks – that looks really promising and like it should achieve what I need.
I’ve just tried it, and it looks like the conditional is evaluating false on is_category() (I have removed the two last conditions to see if it was an issue with class name). The element’s display rule is set to render on a custom taxonomy archive that is rendering a WooCommerce template – would this have an effect on this working?
I can’t remove the is_category() check without triggering a critical error, so am not sure where to go from here to diagnose.
For what it’s worth, I also noticed that GenerateBlocks is having an issue in the element on the archive page – it’s not rendering a headline with dynamic content where there are no posts in the loop of the archive page – not sure if it’s related to this issue, but just thought I’d mention as that’s two issues on the same archive.
Thanks in advance for any light you can shed – and sorry for coming back to you on what should have been an easy answer!

Hi Sam,
render_block()should work anywhere even on Custom Taxonomy archive pages. Try replacingis_category()withis_tax().David’s code is just an example of its usage. It needs modifications for it to work as you would prefer.
Can you provide admin login credentials so we can have a better grasp of the concept?

Ah, all sorted now – thanks for coming back to me. Turns out it needs to return a blank string rather than null or else a core function trips out:
[15-Nov-2022 07:16:24 UTC] PHP Fatal error: Uncaught TypeError: Argument 1 passed to Automattic\WooCommerce\Blocks\BlockTypes\ClassicTemplate::add_alignment_class_to_wrapper() must be of the type string, null given, called in /home/wp-includes/class-wp-hook.php on line 310 and defined in /home/wp-content/plugins/woocommerce/packages/woocommerce-blocks/src/BlockTypes/ClassicTemplate.php:233Still need to figure out the weird GB dynamic data thing, but looks like that’s now not for this thread.
Thanks for your help with this.
I see. You’re welcome Sam! Feel free to raise a new topic if you have any further issues.
