* I`m trying to build testimonial blocks, and want to add stars equal to the ACF
custom field. For now, I have this code:
* ```wp-block-code
$stars_value = get_post_meta(get_the_ID(), 'stars', true);
// Maximum stars to display
$max_stars = 5;
for ($i = 1; $i <= $max_stars; $i++) {
// Check if the current star
$star_class = ($i <= $stars_value) ? 'filled' : 'empty';
// Modify the block content here
echo '';
}
```
* which works correctly except for the fact that WP get_post_meta(get_the_ID(),‘
stars’, true); returns the current page ID, which is correct behavior, so I used
render block to change the query loop block like this:
* ```wp-block-code
add_filter('render_block', function($block_content, $block) {
if (!empty($block['attrs']['className']) && 'stars-holder' === $block['attrs']['className']) {
$stars_value = get_post_meta(get_the_ID(), 'stars', true);
// Maximum stars to display
$max_stars = 5;
for ($i = 1; $i <= $max_stars; $i++) {
// Check if the current star
$star_class = ($i <= $stars_value) ? 'filled' : 'empty';
// Modify the block content here
$block_content .= '';
}
}
return $block_content;
}, 10, 2);
```
* But it’s not working for some reason; perhaps you can help me identify my mistakes?
Thanks.
