How to filter the post that titis is empty

[liunaijie]

When generate post, it will read all files under _posts folder, I want to filter some file that not write the title.

I try to use Filter function to do this, I write a simple code like this and post it to scripts/filterNoTitle.js

hexo.extend.filter.register('before_post_render', function(data) {
    if (!data.title) {
        console.log('No title post, Skip generate file');
        return false;
    }
    return data;
}, 1);

When run this, it can list the file that title is empty, but It will get exception like this

TypeError: Cannot read properties of undefined (reading 'includes')
    at Hexo.backtickCodeBlock

It looks the downstream Filter still run.

Hexo allows posts to have empty titles, so it doesn't perform any special handling for them. If you want to hide these posts, you can set published: false in the Front-matter. See #5122

Hi, thanks for the response.
Is there any posible to use Filter feature to do this? https://hexo.io/api/filter
When find the title is empty, ignore to generate the post. When I add the code I mentioned above, it looks the filter is not working, it will still run the next filteres.

You mentioned published : false need to add on each postes, So I want to look up is there any posible to use code to filter those postes.
