Hi there,
Are these parameters in the URL? If so, it wouldn’t be too hard to do right now..
For example, if you’re using the block editor, you could do this:
add_filter( 'render_blocks', function( $content ) {
$text_to_replace = isset( $_GET['my-param'] ) ? $_GET['my-param'] : false;
$text_to_look_for = '{{replace_me}}';
if ( $text_to_replace ) {
$content = str_replace( $text_to_look_for, esc_html( $text_to_replace ), $content );
}
return $content;
} );
Just a very basic example 🙂
