在您看来,您必须执行以下操作
@foreach($student_id as $student)
<p> {{ $student->name }} </p>
@endforeach
@foreach($student\u id作为$student)
{{$student->name}
@endforeach
name属性是数据库中的表
这是如果您正在使用刀片引擎,或者使用普通的php标记
然后在你的路径中,你必须告诉你的控制器中你想要使用什么方法,即使你的函数被称为索引,在你的路径上指定函数是一个很好的实践。要有一个好的代码结构,请记住类总是以大写字母开头
我强烈建议您使用eloquent而不是query builder。首先,我建议您仔细查看一下,以便了解一下框架。现在,有几件事
在Laravel中,在编写迁移时,不要将它们命名为Student.php
。使用命令php artisan make:migration create_students_table
。标准命名约定用于描述迁移的操作李>
如果要插入某些数据,请不要在迁移中插入。相反,请查看设置李>
对于你的学生
,我非常建议你创建一个模型。Laravel是一个MVC框架,如果您不习惯MVC结构,这可能与您习惯的有点不同。模型只是逻辑上捆绑在一起的一些数据集合的表示。在您的数据库中,这些数据最终是一行中的数据。然后可以执行Student::all()
从students
表中检索所有数据
Laravel中的命名约定规定了camelCase的使用。因此,您的所有文件都应该像您的类一样以驼峰大小写命名。也就是说StudentController.php
和class StudentController
在routes.php
中,指定要调用的方法:Route::get('student',['as'=>'student','uses'=>'StudentController@index']);代码>
再次,请看一看开始链接的Laravel 5基础系列。在那里你将学会正确处理拉威尔 您必须在Laravel中打开调试,以查看错误是什么。下面是方法:你为什么不使用种子?@madforstrength我试过使用它,但它说,无效参数例外你发布的代码没有显示你如何试图检索视图中的数据?它如何检索@Jeemusu?你能帮我一下吗?因为查询生成器返回了一个数组,所以它不起作用,所以宁可$student['name']
:)@phroggy不,它不返回数组,看看这个@phroggy没问题:)谢谢大家的分享!!最后,我做到了!:')
@foreach($student_id as $student)
<p> {{ $student->name }} </p>
@endforeach
