I have created a custom block with a dateFrom and dateTo attribute (which work), but would like to hide the block on the front end between these dates.
Not sure if this is even possible?
I don't just want to add a class and hide with css, as i don't want the block to be visible, even in the code. Any advise or pointing me in right direction would be appreciated.

UPDATE
I have tried to add and remove filter as below, but i can't seem to get the BlockName to output
remove_filter( 'the_content', 'do_blocks', 7 );
add_filter( 'the_content', function( $content ) {
$blocks = gutenberg_parse_blocks( $content );
$output = '';
foreach ( $blocks as $block ) {
if ( 'block/timed-block' === $block['blockName'] ) {
$output .= '';
} else {
$output .= gutenberg_render_block( $block );
}
}
return $output;
}, 10, 2 );

Reset to default 7Here's an untested suggestion, to remove an HTML block of type:
<!-- wp:block/timed-block {"dateFrom":"2018-11-14", "dateTo":"2018-12-18"} -->
<section>
...
</section>
<!-- /wp:block/timed-block -->
from the rendered content, using the render_block filter (available in 5.0+):
add_filter( 'render_block', function( $block_content, $block ) {
// Remove the block/timed-block from the rendered content.
if ( 'block/timed-block' === $block['blockName'] ) {
$block_content = '';
}
return $block_content;
}, 10, 2 );
One could further handle date constrains with the parsed attributes $block['attr']['dateFrom'] and $block['attr']['dateTo'] as needed.
Hope it helps!
do_blockfilter, that might have been renamedrender_block. Match the corresponding block, peek into the date attributes and remove the block from the rendered content if it matches the correct condition? – birgire Commented Nov 14, 2018 at 21:17
