How can I pre-fill form data entered by a user in Laravel 7 - laravel

Question

I'm making a registration form where users will be redirected to a preview page to confirm their details first before submitting the form. I'm using Laravel 7 and I'm quite new to Laravel. Once the user enters their details in registration form, the same details will be pre-filled in the preview form before submission. I have tried some code in my controller but it's giving me an error Trying to get property 'myForm' of non-object In my Controller, $data is an array, I'm not sure how I can achieve this. Please help.
In my Conroller:
public function confirmation(Request $request)
{
$categories = Category::all();
$request->validate([
'first_name' => 'required|string|max:255',
'last_name' => 'required|string|max:255',
'telephone_number' => 'required|digits:10',
'email' => 'required|string|email|max:255|unique:users','regex:/^[\w\-\.\+]+\#[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,6}$/',
'password' => 'required|string|min:6|confirmed',
'password_confirmation' => 'required',
'region' => 'required|string',
'description' => 'required|string|max:2500',
'start_date' => 'required|date',
'client_region' => 'string|max:500',
'client_category' => 'integer|max:255',
]);
$data['myForm'] = $request->all();
return view('auth.client.preview', compact('categories', 'data'));
}
In my blade view:
<div class="form-group">
<label for="first_name">First Name</label><span class="text-danger">*</span>
<input type="text" class="form-control{{ $errors->has('first_name')?'is-invalid':'' }}"
name="first_name" value="{{$data->myForm['first_name']}}"
placeholder="Enter First Name" autofocus tabindex="1" required>
<div class="invalid-feedback">
{{ $errors->first('first_name') }}
</div>
</div>
My Route:
Route::post('/preview-details', 'Auth\Client\PreviewRegisterDetailsController#confirmation')->name('preview-details');
Dropdown List:
<label for="fundi_type">Fundi Type</label><span class="text-danger">*</span>
<select class="custom-select" id="category_id" name="category_id">
#foreach($categories as $category )
<option value="{{ $category->id }}">{{ $category->name }}</option>
#endforeach
</select>

Answer 1

Simplify like this below .So no need to create extra array key .
$myForm = $request->all();
return view('auth.client.preview', compact('categories', 'myForm'));
and in view
<input type="text" class="form-control{{ $errors->has('first_name')?'is-invalid':'' }}"
name="first_name" value="{{$myForm['first_name']}}"
placeholder="Enter First Name" autofocus tabindex="1" required>
Updated
<option value="{{ $category->id }}" {{($myForm['category_id']==$category->id)?'selected':null}}>{{ $category->name }}</option>

Edit your blade file code.
Actually your controller is sending array and you are accessing that array as a collection.
From :
<input type="text" class="form-control{{ $errors->has('first_name')?'is-invalid':'' }}"
name="first_name" value="{{$data->myForm['first_name']}}"
placeholder="Enter First Name" autofocus tabindex="1" required>
To
<input type="text" class="form-control{{ $errors->has('first_name')?'is-invalid':'' }}"
name="first_name" value="{{$data['myForm']['first_name']}}"
placeholder="Enter First Name" autofocus tabindex="1" required>
Hope this will be useful.
