Laravel Eager Loading with Condition | All About

Laravel is a popular PHP frameworks. It offers developers a wide range of powerful features and functionalities.

One such feature is eager loading. It allows us to access related data more easily. Furthermore, we can include conditions in eager loading. Today, we are going to take a look at how to use the whereHas method in Laravel to perform eager loading with custom conditions.

In Laravel, we can use eager loading with conditions using the whereHas method. This method allows us to include additional conditions on the eager loaded relationship.

Let’s take a look at an example:

$posts = Post::with(['comments' => function ($query) { $query->where('approved', true); }])→get();

Here, we have a Post model that has a one-to-many relationship with a Comment model. We will eager load approved comments.

The with method specifies the relationship to be eager loaded. Here, we are eager loading the comments relationship. Then, we use the where method on the $query object to add the additional condition.

As a result, all the posts with their approved comments are loaded. In case a post does not have any approved comments, it will be loaded without any comments.

We can adjust the condition inside the where method to meet our needs. Additionally, we can use other query builder methods to add more complex conditions.

Our experts would like to remind you to replace Post and Comment with the actual model names and define the relationships in the models.
