如何从数据库中检索数据到laravel PHP中表单的输入值中以完成更新操作？

Question

I'm trying to populate data into input values from mysql database so that I can see and change the data.

I have a form named form.blade.php which will be included in both create.blade.php and edit.blade.php . What I need is to know is how to retrive data from database to populate data to those inputs when I click on edit.Then when I click on Add button in index.blade.php ,I'll be redirected to create.blade.php and then inputs must be empty.

I tried to add some code functions to every input value

{{old('title',$page->title}}  then {{ isset($page) ? page->title: ''}}

but its not working

I'm using one form to perform create and update actions

This is the edit.blade.php

@extends('layouts.master')
@section('content')

    <div class="card">
        <div class="card-header card-header-success">
            <h4 class="card-title ">Pages Data Table</h4>
            <p class="card-category"> Here you can update Page data</p>
        </div>
        <div class="card-body">

            {!! Form::open(['action' => 'PagesController@store', 'method' => 'POST' ]) !!}
                @csrf
                @method('PUT')
                @include('pages.includes.form')
            {!! Form::close() !!}
    </div>
    </div>


@endsection

and this is the child form form.blade.php

    <div class="form-group">
        {{Form::label('title', 'Title')}}

  {{ Form::text('title', '',['class' => 'form-control', 'placeholder' => 'Title']) }}

    </div>
    <div class="form-group">
        {{Form::label('content', 'Content')}}
        <br>
        {{ Form::textarea('content', '',['class' =>'form-control', 'placeholder'=> 'Content']) }}
    </div>
    <div class="form-group">
            <div class="form-check form-check-radio">
                    <label class="form-check-label">
                            {{Form::input('radio','status', '0',['class' => 'form-check-input','checked'=>'checked'])}} Status Off
                        <span class="circle">
                            <span class="check"></span>
                        </span>
                    </label>
                </div>
                <div class="form-check form-check-radio">
                    <label class="form-check-label">
                            {{Form::input('radio','status', '1',['class' => 'form-check-input'])}} Status On
                        <span class="circle">
                            <span class="check"></span>
                        </span>
                    </label>
                </div>

    </div>

    <input type="submit" name="submit" class="btn btn-success" value="Save">

When you are using the same form for create and update, you can use the optional method.

<input type="text" class="form-control{{ $errors->has('date') ? ' is-invalid' : '' }}" name="date" id="date" value="{{ old('date', optional($expense)->date) }}">

In the create function send the variable as null like $expense = null; And in edit function the variable has its own value from database. So when the variable has its value the input field will be filled by value from database otherwise it will be empty.
