But for now, let’s see how can we use it. Now we won’t cover how does it work, but if you are interested, you can read further here. ![]() We can’t use the LIKE keyword here, but we don’t have to since we have the SOUNDS LIKE keyword. What if the user mistypes the expression? It would be nice to check if is there any record in the database that is similar to the given expression. Now let’s move on the last thing we want to cover today. A little bit tricky solution, but works perfectly! It “Sounds Like” … We convert the given value, and the stored valued to lower case, then compare them. Now let’s move on the real point: we use lower() function because this way we can ensure case-insensitivity on JSON columns. The first item of the array goes for the first binding, the second one for the second binding and so on. As you can see, we pass an array as the second parameter. It’s a nice way to protect yourself against vulnerable values. The other thing is the ? sign in the second lower function. First of all the syntax is not that clean like above, because we are passing a raw expression here and not a sanitized one. We can use the % character for wildcards: get() We can use wildcard expressions, and those make things a lot more fun.

The point is, we have a lot more flexibility than a regular equality check. To take a step further, let’s take a look at the LIKE MySQL keyword. It is lightning fast by using a bounding box to cut down the possible results and calculating the distance only on the remaining subset. Laravel Geoly provides a convenient way for your Laravel Eloquent models to query in a certain radius around a position. The isDirty method determines if any of the model's attributes have been changed since the model was retrieved. We strongly suggest reading the docs about it. Perform fast and efficient radius searches on your Laravel Eloquent models. Eloquent provides the isDirty, isClean, and wasChanged methods to examine the internal state of your model and determine how its attributes have changed from when the model was originally retrieved. This property maps various points of the Eloquent model's lifecycle to your own event classes.There are a lot of possibilities to combine your where clauses. To start listening to model events, define a $dispatchesEvents property on your Eloquent model. ![]() Event names ending with -ing are dispatched before any changes to the model are persisted, while events ending with -ed are dispatched after the changes to the model are persisted. ![]() The saving / saved events will dispatch when a model is created or updated - even if the model's attributes have not been changed. The updating / updated events will dispatch when an existing model is modified and the save method is called. When a new model is saved for the first time, the creating and created events will dispatch. The retrieved event will dispatch when an existing model is retrieved from the database. Want to broadcast your Eloquent events directly to your client-side application? Check out Laravel's model event broadcasting.Įloquent models dispatch several events, allowing you to hook into the following moments in a model's lifecycle: retrieved, creating, created, updating, updated, saving, saved, deleting, deleted, restoring, restored, and replicating. In addition to retrieving records from the database table, Eloquent models allow you to insert, update, and delete records from the table as well. When using Eloquent, each database table has a corresponding "Model" that is used to interact with that table. Laravel includes Eloquent, an object-relational mapper (ORM) that makes it enjoyable to interact with your database.
