Detailed explanation of shared data and view Composer_php examples between Laravel views
1. Share data between views
In addition to passing specified data in a single view, sometimes the same data needs to be passed in all views, that is, we need to share data in different views. To achieve this, you need to use the share
method of the view factory.
Global helper functionview
is similar to response
. If parameters are passed in, an IlluminateViewView
instance will be returned. If no parameters are passed in, an IlluminateViewFactory
instance will be returned. So we can share data between views by using the following method in the boot
method of the service provider:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
|
We define two routes in routes.php
:
1 2 3 4 5 6 7 |
|
Then create a home.blade.php
view file in the resources/views
directory with the following content:
1 |
|
Create another hello.blade.php
view file:
1 |
|
Access http://laravel.app:8000/testViewHello
and http://laravel.app:8000/testViewHome
respectively in the browser, you can parse the value of $sitename
.
2. View Composer
Sometimes we want to bind some specific data to the view every time the view is rendered, such as logged in user information. In this case, we need to use view Composer. View Composer is implemented through the composer method of the view factory. The second callback parameter of this method supports two methods based on controller actions and closure functions.
For the sake of simplicity, we are still based on AppServiceProvider
instead of creating a separate service provider. Here we pass closure parameters (refer to the view document for controller actions):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
|
Modify hello.blade.php
View file:
Welcome to {{$sitename}}!
1 2 3 |
|
Visit http://laravel.app:8000/testViewHello
in the browser, the output content is as follows:
1 2 3 4 5 6 |
|
You can also pass data to multiple views:
1 2 3 |
|
Even all views (use wildcard *):
1 2 3 |
|
The above are the details of sharing data between Laravel views and view Composer. I hope this article will be helpful to everyone learning Laravel.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables.

When developing websites using CraftCMS, you often encounter resource file caching problems, especially when you frequently update CSS and JavaScript files, old versions of files may still be cached by the browser, causing users to not see the latest changes in time. This problem not only affects the user experience, but also increases the difficulty of development and debugging. Recently, I encountered similar troubles in my project, and after some exploration, I found the plugin wiejeben/craft-laravel-mix, which perfectly solved my caching problem.

Efficiently process 7 million records and create interactive maps with geospatial technology. This article explores how to efficiently process over 7 million records using Laravel and MySQL and convert them into interactive map visualizations. Initial challenge project requirements: Extract valuable insights using 7 million records in MySQL database. Many people first consider programming languages, but ignore the database itself: Can it meet the needs? Is data migration or structural adjustment required? Can MySQL withstand such a large data load? Preliminary analysis: Key filters and properties need to be identified. After analysis, it was found that only a few attributes were related to the solution. We verified the feasibility of the filter and set some restrictions to optimize the search. Map search based on city
