assuming that list_type is the name of the select box to choose from (values : selling or rent)
use it this way
"sale_price" => "required_if:list_type,==,selling"
what does this mean? :
the sale price is only required if the value of list_type is equal to selling
do the same for rent_price
edit
public function rules()
{
return [
'list_type' => 'required',
'sale_price' => 'required_if:list_type,==,For Sale',
'rent_price' => 'required_if:list_type,==,For Rent'
}
There can be another situation when, the requirement will be required if another field is not present, if someone is in this situation, you can do
'your_field.*' => 'required_unless:dependency_field.*,
You could use the Illuminate\Validation\Rules\RequiredIf
rule directly.
Note: This rule is available in Laravel 5.6 and up.
class SomeRequest extends FormRequest
{
...
public function rules()
{
return [
'sale_price' => new RequiredIf($this->list_type == 'For Sale'),
'rent_price' => new RequiredIf($this->list_type == 'For Rent'),
];
}
}
And if you need to use multiple rules, then you can pass in an array.
public function rules()
{
return [
'sale_price' => [
new RequiredIf($this->list_type == 'For Sale'),
'string',
...
]
];
}
You can use Illuminate\Validation\Rule
in Laravel as given below to build the validator.
$validator = Validator::make( $request->input(), [
'list_type' => 'required',
'sale_price'=> Rule::requiredIf( function () use ($request){
return $request->input('list_type') == 'For Sale';
}),
'rent_price'=> Rule::requiredIf( function () use ($request){
return $request->input('list_type') == 'For Rent';
}),
]);
