{
// Verify using VerifyRequest
$validated = array_merge($request->validated(), ['token' => Str::random(127)]);
// the error in this line
if($validated->validate()->fails()){
return redirect(url()->previous() . '#verify-email')->withErrors($request)->withInput();
}
// end the error
// create
Pengaduan::create($validated);
// Setup the email message
$data = [
'content' => 'to create complaint please click the link below',
'url' => 'http://127.0.0.1:8000/complaint/create/' . $validated['token'],
];
// Send to email
Mail::to($validated['email'])->send(new VerifyAlternative($data));

->route('complaint.check')
->with('success', 'Register success. Please Check your email');
}
#endif
here's in my VerifyRequest
class VerifyRequest extends FormRequest
{
public function authorize()
{
return true;
}
public function rules()
{
return [
'email' => ['required', Rule::unique('complaints')],
];
}
public function messages()
{
return [
'email.unique' => 'This email is making a Complaint. Wait for the complaint to be completed to make a complaint again'
];
}
protected function prepareForValidation()
{
$this->merge([
'email' => $this->email . '#univesity.com',
]);
}
}
Can anyone help me to solve this as soon as posible. Thank you in advanced
