Using corcel to add a category to a post

Question

I am using "jgrossi/corcel": "3.0.0", Laravel 6.16.0 and PHP 7.4.1

I would like to add an existing category Product to my new post in wordpress. However, I am not sure how to do this.

I can create a wordpress post the following way:

        $post = new Post();
        $post->post_title = $title;
        $post->post_content = $msg;
        $post->save();

Any suggestions how to use corcel to add an existing category to the post?

Appreciate your replies!

The Post model has a belongsToMany relationship to the taxonomies model, as you can see here...

/**
 * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
 */
public function taxonomies()
{
    return $this->belongsToMany(
        Taxonomy::class,
        'term_relationships',
        'object_id',
        'term_taxonomy_id'
    );
}

//Source: https://github.com/corcel/corcel/blob/5.0/src/Model/Post.php
//Lines: 185-196

Therefore you should be able to link the post to a category using the category id like so...

$post->taxonomies()->associate($taxonomyId);
