Question

I am writing the logic for an edit form and have some complications when displaying data in the inputs.

When I initially show the form, I show the records values like:

Answer 1

There is nothing wrong with the way you are doing things as Laravel gives multiple ways to handle the situation you're describing.

What I would suggest is using the Laravel Collective Form and HTML packages to build your form. This package will automatically handle binding old request values to your form if validation fails

I solved that issue in my application if you want to get old previous inserted value in input you should try this one I did like this.

function SaveData(Request $request)
{
       $sValidationRules = [
        'firstname' => 'required',
        'lastname' => 'required',
        'email' => 'required',
        'phone' => 'required',
      ];

      $validator = Validator::make($request->all(), $sValidationRules);

      if ($validator->fails()) // on validator found any error 
      {
        // pass validator object in withErrors method & also withInput it should be null by default
         return redirect('Your Route Hare')->withErrors($validator)->withInput();
      }


      Employee::create($request->all());

      return redirect(' your route hare ');
}

& after then get old data in input field value like this using {{ Request::old('firstname') }} Happy Coding. :)

<input type="text" name="firstname" id="firstname"  value="{{ Request::old('firstname') }}" class="form-control" placeholder="First Name">

Old Data: input type text | phone | number | ...

 <input type="text" name="my_text" value="{{old('my_text')}}">

Old Data: input type checkbox | radio

 <input type="checkbox" {{ old('my_checkbox') == 'on' ? 'checked' : '' }} name="my_checkbox">

Answer 4

I know this has already been answered but I thought I would leave a little snippet here for others in the future.

Setting old value on input as @ikurcubic posted can be used the same way on radio button or select:

<input type="text" name="name" value="{{ old('name', $DB->default-value) }}" />

Select option:

<option value="Jeff" {{ old('name', $DB->default-value) == 'Jeff' ? 'selected' : '' }}>Jeff</option>

Radio Button:

<input type="radio"  name="gender" value="M" {{ old('name', $DB->default-value)== "M" ? 'checked' : '' }} />

Another way of doing it; write a small if statement to determine which value should be evaluated:

@php                                  
if(old('name') !== null){
    $option = old('name'); 
}
else{ $option = $database->value; }
@endphp

<select name="name">
   <option value="Bob" {{ $option == 'Bob' ? 'selected' : '' }}>Bob</option>
   <option value="Jeff" {{ $option == 'Jeff' ? 'selected' : '' }}>Jeff</option>
</select>


<input type="radio"  name="gender" value="M" {{ $option == "M" ? 'checked' : '' }} />

<input type="radio"  name="gender" value="F" {{ $option == "F" ? 'checked' : '' }} />

Setting old value of input with an array name e.g name="name[]":

<input type="text" name="name[]" value="{{ old('name.0) }}" />

This will give you the old value of the input with an index of 0.

I have tested this and it works.

Answer 5

Another way to do that is get the data from the dog class, like this:

value="{{old('title') ?? $dog->title }}"

Why? Because old() is for validation; when you fail validation, the input will remain available in the field. In the case where validation hasn't fired yet, value will be filled with $dog->title.

Answer 6

Function old have default parameter if no old data found in session.

function old($key = null, $default = null)

You can replace expression in template with

value="{{old('title', $dog->title)}}"
