Filter getSaveElement and innerBlocks

[sbouey]

Hi,

I'm the author of the Falang multilanguage plugin for wordpress (https://wordpress.org/plugins/falang/), trying to add a feature allowing site admins to translate their site from inside the gutenberg bloc editor

I have already make this with Elementor/Divi/Yootheme/WPbakery

The principle is to dynamically add some attributes you have to translate like input text/content/image depending of the block type

• The content for the heading block
• The image and alt text for the image block
• ...

For this i use the filter getSaveElement from #gutenberg/packages/blocks/src/api/serializer.js

The serializer.js funtion has this signature
export function getSaveElement(blockTypeOrName,attributes,innerBlocks = [])

in the serializer the filter i used but the innerBlocks are not in the parameters

return applyFilters('blocks.getSaveElement',element,blockType,attributes);

my Filter getSaveElement parse the attribute for each languages and i store the render

All work fine for simple blocks but for block like core/list-item it doesn't , probably due to the innerBlocks not set correctly (not set an empty array is used)

Here is a part of the function use for the getSaveElement Filter (call saveContentOrg function)

`
function saveContentOrg( element, blockType, attributes ) {

.......

Object.values(langues)
.forEach((langue) => {
let locAttributes = {...attributes}
attribs_to_change_content.forEach(attr => {

       let encodedValue = attributes[attr + langue.js_locale];
       if (encodedValue) {
           locAttributes[attr] = decode64(encodedValue)
       }
   })
   if (blockType.name != 'core/list-item'){
       var localised_content = blockType.save({attributes: locAttributes, innerBlocks: []})
   } else {
       //var localised_content = '<li>'+attributes['content']+'</li>'
   }
   if (localised_content) {
       attributes["render" + langue.js_locale] = encode64(renderToString(localised_content))
   }

})

// return the element wrapped in a div
return element;
}`

my Question is, is there a way to get the innerBlocks of the getSaveElement from the serailized.js in the 'blocks.getSaveElement',

Thanks a lot.
if this is not the right place, just let me know.
