The count() method basically returns the total number of records in result.

All the solutions I can find are those in which there is a deeper relation table1 id is foreign key of table2 and table2 id is foreign key of table3. With SQL if you wanted to get how many records match a specific query, you could use the COUNT(*) function, the syntax would look like this: SELECT COUNT(*) FROM posts WHERE active= '1' I have two tables sizevariations and subcategories, these tables are linked through another table that has both of their ids as foreign key. This could be quite handy when displaying the posts on a website for example, that way you could indicate that the user has not yet added any posts. The syntax is the same: $posts = Model::where( 'active', true)->get() Similar to the isEmpty() method, there is a isNotEmpty() method. Returns true when there are *no* posts
