[英]how to retrieve data using laravel
我是 php 的新手,尤其是 laravel 框架。 有人可以幫我解決嗎? 我不知道如何使用 php: laravel 框架從數據庫中檢索數據。

在您看來,您必須執行以下操作
@foreach($student_id as $student)
<p> {{ $student->name }} </p>
@endforeach
name 屬性是你在數據庫中的表這是如果你使用刀片引擎,否則使用普通的 php 標簽
然后在你的路線中,你必須告訴你想要使用控制器中的什么方法,即使你的函數被稱為 index ,在你的路線上指定函數是一種很好的做法。 要擁有一個好的代碼結構,請記住類總是以大寫字母開頭
我強烈建議您使用 eloquent 而不是查詢構建器
首先,我建議您閱讀Laravel 5 Fundamentals以了解有關該框架的一些知識。 現在,有幾件事。
Student.php
之類的東西。 使用命令php artisan make:migration create_students_table
。 標准命名約定是描述遷移的操作。Student
我非常建議您創建一個模型。 Laravel 是一個 MVC 框架,如果你不習慣 MVC 結構,這可能和你習慣的有點不同。 模型只是邏輯捆綁在一起的某些數據集合的表示。 在您的數據庫中,這些數據最終排在一行。 然后,您可以執行Student::all()
從您的students
表中檢索所有數據。StudentController.php
和class StudentController
routes.php
,指定調用哪個方法: Route::get('student', ['as' => 'student', 'uses' => 'StudentController@index']);
同樣,請查看開頭鏈接的 Laravel 5 基礎知識系列。 您將在那里學習如何正確處理 Laravel。
