thank you, it has worked for me ok.
Also managed to solve this reading trough this topic, thank you all! My solution may work for others so also posting it here:
In my “block.json”:
{
"name": "acf/my-acf-block",
"title": "My ACF Block",
"description": "Description of this block.",
"style": "file:./my-acf-block.css",
"category": "my-custom-category",
"icon": "random-icon-or-svg",
"textdomain": "my-textdomain",
"acf": {
"mode": "edit",
"renderTemplate": "my-acf-block.php"
},
"supports": {
"align": [
"full"
]
},
"example": {
"attributes": {
"mode": "preview",
"data": {
"preview_image_my_acf_block": "assets/img/my-placeholder.jpg"
}
}
}
}
And in “my-acf-block.php” I start with:
<?php
if( isset( $block['data']['preview_image_my_acf_block'] ) ) {
echo '<img src="' . CONSTANT_THEME_URL . $block['data']['preview_image_my_acf_block'] . ' " style="width: 100%; height: auto;">';
return;
}
// the rest of my template render..
?>
The “CONSTANT_THEME_URL” is a constant that I normally define within my theme and returns the URL of the current theme, but including trailingslashit().
