How to show old data of dynamic checkbox in Laravel

Question

I am using Laravel 5.3,this is a form demo below:

<div class="container">
    <form>
        <div class="form-group row">
            <label for="name" class="col-sm-2 col-form-label">Name</label>
            <div class="col-sm-10">
                <input type="text" class="form-control" id="name" name="name" value="{{ old('name', $student->name)}}">
            </div>
        </div>

        <fieldset class="form-group row">
            <legend class="col-form-legend col-sm-2">Gender</legend>
            <div class="col-sm-10">
                <div class="form-check">
                    <label class="form-check-label">
                        <input class="form-check-input" type="radio" name="gender" value="1" @if(old('gender',$student->gender)=="1") checked @endif>
                        Male
                    </label>
                </div>
                <div class="form-check">
                    <label class="form-check-label">
                        <input class="form-check-input" type="radio" name="gender" value="2" @if(old('gender',$student->gender)=="2") checked @endif>
                        Female
                    </label>
                </div>
            </div>
        </fieldset>
        <div class="form-group row">
            <label class="col-sm-2">Hobbies</label>
            <div class="col-sm-10">
                <div class="form-check">
                    <label class="form-check-inline">
                        <input class="form-check-input" type="checkbox" name="hobby[]" value="1" @if(...) checked @endif> football
                    </label>
                    <label class="form-check-inline">
                        <input class="form-check-input" type="checkbox" name="hobby[]" value="2" @if(...) checked @endif> basketball
                    </label>
                    <label class="form-check-inline">
                        <input class="form-check-input" type="checkbox" name="hobby[]" value="3" @if(...) checked @endif> swimming
                    </label>
                </div>

            </div>
        </div>
        <div class="form-group row">
            <div class="offset-sm-2 col-sm-10">
                <button type="submit" class="btn btn-primary">Submit</button>
            </div>
        </div>
    </form>
</div>

My question is:

I can show old data in input type="text" like this:

<input type="text" class="form-control" id="name" name="name" value="{{ old('name', $student->name)}}">

And I can show old data in input type="radio" like this:

<input class="form-check-input" type="radio" name="gender" value="1" @if(old('gender',$student->gender)=="1") checked @endif>

But I don't know how to show old data in input type="checkbox":

<input class="form-check-input" type="checkbox" name="hobby[]" value="3" @if(...) checked @endif>

How to do it?

Hello @kartik,

This will work:

        <div class="form-check">
            <label class="form-check-inline">
                <input class="form-check-input" type="checkbox" name="hobby[]" value="1" @if(is_array(old('hobby')) && in_array(1, old('hobby'))) checked @endif> football
            </label>
            <label class="form-check-inline">
                <input class="form-check-input" type="checkbox" name="hobby[]" value="2" @if(is_array(old('hobby')) && in_array(2, old('hobby'))) checked @endif> basketball
            </label>
            <label class="form-check-inline">
                <input class="form-check-input" type="checkbox" name="hobby[]" value="3" @if(is_array(old('hobby')) && in_array(3, old('hobby'))) checked @endif> swimming
            </label>
        </div>

Also as brokekidweb suggested :

<label class="form-check-inline">
    <input class="form-check-input" type="checkbox" name="hobby[]" value="1" {{ (is_array(old('hobby')) and in_array(1, old('hobby'))) ? ' checked' : '' }}> football
</label>

Hope it works!!

Thank You!!

<label class="form-check-inline">
    <input class="form-check-input" type="checkbox" name="hobby[]" value="1" {{ (is_array(old('hobby')) and in_array(1, old('hobby'))) ? ' checked' : '' }}> football
</label>

The repopulation part is working, but how do you pass/read the from that part?
for example,

$data = array(

            'hobby' => $request->hobby,

);
