In Laravel, the controller can pass data to the view through the view() function or the with() method. 1. When using view(), data is passed in as the second parameter, such as return view('welcome', ['name' => 'John']), which is suitable for passing multiple variables at once; 2. When using with(), add variables one by one through chain calls, such as return view('welcome')->with('name', 'John'), which is suitable for using when dynamically judging conditions; 3. You can also pass in arrays in with() to pass multiple variables at once to keep the code neat. Two methods can be selected according to habits or scenes.
In Laravel, it is a common operation for the controller to pass data to the view. Usually we will use the view() function and pass an array or use the with() method to implement this process.
Use view() to pass data
When you call the view() function in the controller, you can pass the data in as a second parameter. For example:
return view('welcome', ['name' => 'John']);
In this example, welcome is the view name and the second parameter is an array containing the data to be passed to the view. You can access this variable through $name in the view.
This method is suitable for passing multiple variables at once, with clear structure and easy to maintain.
Use the with() method to pass data
Another way is to use the with() method:
return view('welcome')->with('name', 'John');
This has the same effect as the example above, but the writing method is different. with() is more suitable for adding variables one by one, especially when you need to dynamically decide whether to pass a variable based on the conditions.
for example:
- If you only pass one variable, using
with()is more intuitive. - If there are multiple variables, it is more convenient to use
with()multiple times or use the array directly.
Notes and details
Sometimes novices will confuse the order of variable names and values. Remember, the first parameter of with($key, $value) is the variable name in the form of a string, and the second is the actual value.
If you want to pass multiple variables, you can also write this:
return view('welcome')->with([
'name' => 'John',
'age' => 30
]); This also keeps the code neat and avoids repeated writing with() .
Basically that's it. Both methods can be used depending on which style you prefer.

How do I define methods (actions) in a controller?
Jun 14, 2025 am 12:38 AM
Defining a method (also known as an action) in a controller is to tell the application what to do when someone visits a specific URL. These methods usually process requests, process data, and return responses such as HTML pages or JSON. Understanding the basic structure: Most web frameworks (such as RubyonRails, Laravel, or SpringMVC) use controllers to group related operations. Methods within each controller usually correspond to a route, i.e. the URL path that someone can access. For example, there may be the following methods in PostsController: 1.index() – display post list; 2.show() – display individual posts; 3.create() – handle creating new posts; 4.u
