Eloquent Queries 291 Update We don’t have to simply retrieve model instances, we can also change them. Using the update() method we can update the values of the table rows that are the result of the Eloquent query. Simply pass a key-value array as the first parameter to the update() method to change the column values for each row. The array key represents the name of the column to change, and the value represents the new intended value for the column. The update() method is special, and cannot be used without a constraint, therefore I will use a simple where() constraint within the example. If you don’t understand it, then don’t worry about it. We will cover constraints in detail within the next section. Here’s an example that will modify our albums table. (Don’t worry, I will restore it for the next example.) 1
Eloquent Queries 292 15 }, 16 { 17 id: 3, 18 title: "Leaving Through The Window", 19 artist: "Something Corporate", 20 genre: "Piano Rock", 21 year: 2002 22 }, 23 { 24 id: 4, 25 title: "North", 26 artist: "Something Corporate", 27 genre: "Piano Rock", 28 year: 2002 29 }, 30 { 31 id: 5, 32 title: "...Anywhere But Here", 33 artist: "The Ataris", 34 genre: "Punk Rock", 35 year: 1997 36 }, 37 { 38 id: 6, 39 title: "...Is A Real Boy", 40 artist: "Say Anything", 41 genre: "Indie Rock", 42 year: 2006 43 } 44 ] As you can see, I’m now a rockstar. Awesome! Delete Much like the update() method, the delete() method will not return any instances. Instead, it will remove the rows that are the result of the query from the database table.
