{{$cqh}}
Now the requirement is that every page will use this variable, how to share this data?
Generally, I will set this kind of operation in the boot method of the Laravel service. Here are two ways to share data.
Method 1: use the View:share method, such as in CqhServiceProvider
one
two
three
four
Public function boot ()
{
View::share ('cqh','chenqionghe')
}
This is using the appearance mode, or you can use the view () method directly
one
View ()-> share ('cqh',' chenqionghe')
Method 2: use the composer method to transfer data to the navigation.blade.php separately, as follows
one
two
three
four
five
six
Public function boot ()
{
View ()-> composer ('navigation', function ($view) {
$view- > with ('cqh','chenqionghe')
});
}
The above is done in the form of a closure, which, like routing, can also be replaced by a class, called a component in Laravel, as follows
one
two
three
four
Public function boot ()
{
View::composer ('navigation',' App\ Http\ ViewComposers\ MyViewComposer')
}
This registers the view component, and each time the navigation view is rendered, the MyViewComposer@compose will be executed.
Let's see how this component is defined.
