Old data can not display in "edit page"

'Old data' is a term related to validation errors. You want to show the values from the database?

the second parameter to the old() function is the original value;

    value="{{ old('name', $person->name)}}">

@Snapey How to show the original values of select,radio and checkbox?

Yes, a bit trickier.

In the case of radio and checkboxes you have to use the old(x,y) function as part of a test to know if the checkbox should be checked or the radio set active.

Checkboxes;

  <input type="checkbox" name="bike" value="Bike" 
    @if(old('bike',$transport->bike))
        checked
    @endif
    > I have a bike<br>

  <input type="checkbox" name="car" value="Car" 
    @if(old('car',$transport->car))
        checked
    @endif
    > I have a car<br>

Same with radio, but you have to compare the value with the radios to see which radio is selected

  <input type="radio" name="gender" value="male"  @if(old('gender',$profile->gender)=='male') checked @endif > Male<br>
  <input type="radio" name="gender" value="female"@if(old('gender',$profile->gender)=='female') checked @endif > Female<br>
  <input type="radio" name="gender" value="other" <?php old('gender',$profile->gender)=='other')?'checked':''; ?> > Other

in the final row, I show it using plain old php instead of blade syntax

Selects are more tricky because you have to test the old value against each of the options.

<select name="cars">

    @foreach($carTypesList as $type =>$name)

          <option value="{{ $type }}"
            @if(old('cars',$profile->car) == {{ $type }})
                selected
            @endif 
                >{{ $name }}
        </option>
        
    @endforeach 

</select>

if you don't like mixing in the test in with the html so much, you could duplicate the line like;

<select name="cars">

    @foreach($carTypesList as $type =>$name)

        @if(old('cars',$profile->car) == $type )
             <option value="{{ $type }}" selected >{{ $name }}</option>
        @else
             <option value="{{ $type }}">{{ $name }}</option>
        @endif
        
    @endforeach 

</select>

Whilst this is not 'dry' it's easier to read and therefore quicker to work with.

@Snapey thanks a lot!

@Snapey How to show the original values of textarea, and input type="file"?

No idea for file I'm afraid since the server will not remember the file that you selected.

Textarea is very straightforward;

        <textarea name="notes" rows=5 >{{ old('notes',$profile->notes) }}</textarea>

ps. I fixed a couple typos in the earlier posts

@Snapey
Radio: if set rule 'application_way'=>'required',it can not be submitted,if delete this rule ,database can not get checked radio value.

view

<fieldset class="row form-group{{ $errors->has('aplication_way') ? ' has-error' : '' }}">
    <label class="col-xs-2 control-label">aplication way：</label>
    <div class="col-xs-10">
        <div class="c-inputs-stacked">
            <label class="c-input c-radio">
                <input id="radioStacked1" name="aplication_way" type="radio" value="1"
                       @if(old('aplication_way',$person->aplication_way)=='1') checked @endif>
                <span class="c-indicator"></span>
                telephone
            </label>
            <label class="c-input c-radio">
                <input id="radioStacked2" name="aplication_way" type="radio" value="2"
                       @if(old('aplication_way',$person->aplication_way)=='2') checked @endif>
                <span class="c-indicator"></span>
                email
            </label>
        </div>
        @if ($errors->has('aplication_way'))
                                <span class="help-block">
                                        <strong>{{ $errors->first('aplication_way') }}</strong>
                                    </span>
        @endif
    </div>
</fieldset>

controller

    public function store(Requests\StorePersonRequest $request)
    {
        $person = new Person($request->except('photo'));
        $person -> user_id = \Auth::id();

        $file = $request->file('photo');
        $destinationPath = 'uploads/';
        $extension = $file->getClientOriginalExtension();
        $fileName = \Auth::user()->id . '_' . time() . '.' . $extension;
        $file->move($destinationPath, $fileName);
        $person -> image = '/'.$destinationPath.$fileName;

        $person->save();

        return redirect()->action('PersonController@show', ['id' => $person->id]);
    }

StorePersonRequest

    public function rules()
    {
        return [
            'name'=>'required',
            'email'=>'required',
            'profile'=>'required',
            'application_way'=>'required',
            'image'=>'image'
        ];
    }

well, I don't know if its this, but in your rules you have application with two 'p' but in the form its only one.

@Snapey Thanks again! It works!

Hi, I have a form, say for eg. a student edit form inside which contains another form for adding their work experience. After I entered all details like name and all, I clicked on the link to edit my work experience. By the time I return from that form after updating work experience, I lost all that data I entered before (username, email etc.). How can I preserve my data in the first form? I know that's because of page reloading but how can I do this?

@bincy the link to the work experience needs to turn into a form submit button. Then before you show the new form, save all the values of the first.

Then when returning, pull back the data and repopulate the first form.
