Fetching data from Database in Laravel

Title: Efficiently Fetching Data from Database in Laravel for Table Display Introduction Fetcing data from your database is an essential task in any web application development process. In Laravel, there are multiple ways to access and display the data on your website. This comprehensive guide will teach you how to fetch users' data stored in a 'users' table using Laravel 5.5 and show it in an organized table format. Getting Started Firstly, let us examine the provided code snippet:

@extends('layouts.app')

@section('content')

<div class="container">

<h2>Admin Panel</h2>

<p>Data of the Registered Users.</p> 

<table class="table table-bordered">

<thead>

<tr>

<th>Id</th>

<th>Name</th>

<th>Email</th>

</tr>

</thead>

<tbody>

$users = DB::table('users')->select('id','name','email')->get();

@foreach($users as $value)

<tr>

<td>{{ $value->id }}</td>

<td>{{ $value->name }}</td>

<td>{{ $value->email }}</td>

</tr>

@endforeach

</tbody>

</table>

</div>

@endsection

The error message ("Undefined Variable: users") indicates that the $users variable is not defined correctly or at all. To rectify this, we'll first discuss the proper way to fetch data from a database using Laravel 5.5, and then show how to fix your code snippet. Fetching Data from Database in Laravel - Importantly, you should use Eloquent ORM (Object Relational Mapping) for querying your database tables. It offers several advantages over raw SQL queries such as simplicity, flexibility, and readability. - Firstly, define a model class that extends the Laravel's Model class. The model file will contain all the relationships between various entities in your application logic. This helps you easily access and manipulate data without writing complex query statements. - Alternatively, you can use the Eloquent Query Builder for advanced queries. It allows you to perform complex operations on database tables while maintaining a well-defined structure. Fixing the Code Snippet Let's rewrite the code snippet with correct usage of Laravel's Eloquent ORM:

@extends('layouts.app')

@section('content')

<div class="container">

<h2>Admin Panel</h2>

<p>Data of the Registered Users.</p> 

<table class="table table-bordered">

<thead>

<tr>

<th>Id</th>

<th>Name</th>

<th>Email</th>

</tr>

</thead>

<tbody>

$users = User::all();

@foreach($users as $user)

<tr>

<td>{{ $user->id }}</td>

<td>{{ $user->name }}</td>

<td>{{ $user->email }}</td>

</tr>

@endforeach

</tbody>

</table>

</div>
