Insert text before and after a value on a dynamic block

Hi there,

You may try something like this:

add_filter(
    'generateblocks_dynamic_content_output',
    function($content, $attributes) {
        $class_name = $attributes['className'] ?? '';

        if ('dynamic-shortcode' !== $class_name) {
            return $content;
        }

        // Check if the content is a URL (coming from an ACF field)
        if (filter_var($content, FILTER_VALIDATE_URL)) {
            // Create the shortcode
            $shortcode = sprintf(
                '[iframe src="%s" width="640" height="480"]',
                esc_url($content)
            );
            return $shortcode;
        }

        return $content;
    },
    10,
    2
);

Then give the dynamic headline block this CSS class in the “Advanced” panel: dynamic-shortcode

Let me know if that works.

My code might not be working because it’s still outputting the URL even everything looks in order. I tried hardcoding the shortcode with the URL, but it still doesn’t show up on the frontend. Is the URL in the correct embed format?

Try replacing the snippet with this:

add_filter( 'render_block_generateblocks/headline', function( $block_content, $block ) {
    if ( 
        !is_admin() && 
        ! empty( $block['attrs']['className'] ) && 
        strpos( $block['attrs']['className'], 'dynamic-shortcode' ) !== false 
    ) {
        $clean_content = strip_tags($block_content);
        
        $shortcode = do_shortcode('[iframe src="' . esc_url($clean_content) . '" width="100%" height="500"]');
        
        return $shortcode;
    }
  
    return $block_content;
}, 10, 2 );

Glad to hear that!
