laravael 9 Validation Segment with some condition - php

Question

I am working on the online application. it has several sections. some of the sections are shown in some conditions only. some of the validation rules also apply in the dynamic section .how do i segment the validation rule based on the condition.I try following the way and it does not work for me.
$validatedData = $request->validate([
'titel_id' => ['required'],
'initials' => ['required','regex:/^[A-Za-z.]+$/'],
'name_denoted_by_initials' => 'required',
'last_name' => 'required|alpha',
'phone_no' => 'max:12',
/********************************* */
],[
'titel_id.required' => 'the title required',
'initials.required' => 'the name initials required',
'initials.regex' => 'initials only can include letters and dots',
'name_denoted_by_initials.required' => 'the initials denoted name required',
'last_name.required' => 'the last name required',
'phone_no.max' => 'you entered phone number invalid',
]);
if($vacancy->main_category_id == 46){
$validatedData = $request->validate([
'index_no' => 'required',
'year' => 'required|max:'.(date('Y')),
],[
'index_no.required' => 'O/l Exam number is required',
'year.required' => 'O/l Exam year is required',
]);
}
this only shows the without condition validation rule only. how do I manage it?

Answer 1

You can use sometimes() which helps to create Complex Conditional Validation
$validator = Validator::make($request->all(), [
# default validations
]);
$validator->sometimes('index_no', 'required', function ($vacancy) {
return $vacancy->main_category_id === 46;
});
$validator->sometimes('year', 'required|max:'.(date('Y')), function ($vacancy) {
return $vacancy->main_category_id === 46;
});

Update
Saw in the old Laravel doc. If both fields use the same validation, you can merge them.
$validator->sometimes(['index_no', 'year'], 'required', function ($vacancy) {
return $vacancy->main_category_id === 46;
});
Method 02
Create formRequest and validate
php artisan make:request VecancyRequest
In VecancyRequest.php
class VecancyRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
if ($this->get('main_category_id') === 46) {
$rules['index_no'] = 'required';
$rules['year'] = 'required|max:' . (date('Y'));
}
$rules['titel_id'] = 'required';
$rules['initials'] = 'required|regex:/^[A-Za-z.]+$/';
# other validations
return $rules;
}
public function messages()
{
return [
'index_no.required' => 'O/l Exam number is required',
'year.required' => 'O/l Exam year is required',
'titel_id.required' => 'the title required',
'initials.required' => 'the name initials required',
'initials.regex' => 'initials only can include letters and dots',
'name_denoted_by_initials.required' => 'the initials denoted name required',
'last_name.required' => 'the last name required',
'phone_no.max' => 'you entered phone number invalid',
];
}
}
In controller
public function store(VecancyRequest $request)
Remove all validations from the controller. Form Request do the trick
