  // migrations/****_**_**_******_create_category_post_table.php
Schema::create('category_post', function(Blueprint $table) {
    $table->integer('category_id')->unsigned();
    $table->integer('post_id')->unsigned();
    $table->primary(['category_id', 'post_id']);
    $table->foreign('category_id')->references('id')->on('categories')->onUpdate('cascade')->onDelete('cascade');
    $table->foreign('post_id')->references('id')->on('posts')->onUpdate('cascade')->onDelete('cascade');
});


// Post.php
public function categories()
{
    return $this->belongsToMany(Category::class);
}

// Category.php
public function posts()
{
    return $this->belongsToMany(Post::class);
}

In post.php, use this relation: public function categories(){ return $this->belongsToMany(Category::class, 'category_post', 'post_id', 'category_id'); }

//controller
    $post = new Post();
    $post->title = $request->title;
    $post->body = $request->body;
    $post->categories()->attach($request->categories_id);
