How to pass variables to view in laravel
When we develop web applications, we usually do not write static pages. We need to deal with data. So at this time, the question arises. In an MVC framework, how to pass data to the view? ? For example, we want to output a $title variable in the view of the index method of ArticleController. In Laravel, there are several common methods:
Use the with() method
public function index()
{
$title = '文章标题1';
return view('articles.lists')->with('title',$title);
}such with ('title',
title is the value, so we can output this in our articles/lists.blade.php Variables:
<body><h1><?php echo $title; ?></h1></body>
Refresh our blog.dev, you can see a page like this:
In the blade engine, we can output variables like this:
<body><h1>{{ $title }}</h1></body>In fact, in the blade engine, {{ ##title }} will be parsed into output similar to this
title; ?> , but the {{ }} symbol here will output the data as it is. For example, if you write $title like this: public function index()
{
$title = '<span style="color: red">文章</span>标题1'; return view('articles.lists')->with('title',$title);
}<h1>{!! $title !!}</h1>When using this method, you can write like this:
public function index()
{
$title = '<span style="color: red">文章</span>标题1'; return view('articles.lists',['title'=>$title]);
}
public function index()
{
$title = '<span style="color: red">文章</span>标题1'; $intro = '文章一的简介'; return view('articles.lists',[ 'title'=>$title, 'introduction'=>$intro
]);
}['title'=>$title,'introduction'=>$intro]
<h1>{!! $title !!}</h1>{{ $introduction }}
introduction }} instead of {{ intro }}.
Using compact
Using compact is written like this: public function index()
{
$title = '<span style="color: red">文章</span>标题1';
$intro = '文章一的简介';
return view('articles.lists',compact('title','intro'));
}The string of compact() can be the name of the variable, and multiple variable names are separated by commas. At this time, pay attention to changing the variable output of the view.
The above are several methods commonly used in Laravel to pass variables to the view. Just choose a method you like and stick to this way of writing. I use The third type.
