In the next and final part of this series, you’ll create a new command to delete a list of links. You have upgraded the demo application to include a new command that allows users to edit existing links in the database. In a previous part of this series, you learned about how to query the database using Eloquent models. In this guide, you learned how to update database records with Laravel Eloquent. If you must allow the user to select certain columns to query against, always validate the column names against a white-list of allowed columns.

Therefore, you should never allow user input to dictate the column names referenced by your queries, including "order by" columns, etc. As in Laravel > 5.3, if someone is still curious how to do so in easy way its possible by using: updateOrCreate (). PDO does not support binding column names. There is no need to clean strings being passed as bindings. Fortunately, Laravel provides the update(.) method on both the Eloquent and the regular query builder to assist with this. The Laravel query builder uses PDO parameter binding to protect your application against SQL injection attacks. You could use the Laravel query builder, but this is not the best way to do it. The Eloquent collection object extends Laravel's base collection, so it naturally inherits dozens of methods used to. It can be used to perform most database operations in your application and works on all supported database systems. All Eloquent methods that return more than one model result will return instances of the Illuminate\Database\Eloquent\Collection class, including results retrieved via the get method or accessed via a relationship. SELECT, WHERE, HAVING, etc.) have dedicated support methods for using the DB::raw(.) method with them ( selectRaw(.), whereRaw(.), havingRaw(.), etc.), no such method exists for the UPDATE portion of the query (or perhaps more accurately, the SET portion of an update query.)īecause of this, it's also not possible to use PDO parameters with the Eloquent query builder.Laravel's database query builder provides a convenient, fluent interface to creating and running database queries.

The laravel eloquent provides many types of eloquent methods. Unfortunately, usage of this method within the update(.) method is not well documented or supported.

For example, you may want to use a builtin database function (like one of PostgreSQL's JSON functions) in the query to update a column. It can be used to perform most database operations in your application and works perfectly with all of Laravel's supported database systems. It's a common desire to reference other database columns rather than updating records with a static value. Laravel's database query builder provides a convenient, fluent interface to creating and running database queries. Fortunately, Laravel provides the update(.) method on both the Eloquent and the regular query builder to assist with this. It's often more performant to rely on your database's storage engine to do bulk updates to database records rather than looping thru the Eloquent objects and updating them in PHP.
