<input type="text" name="date[]" class="form-control datepicker" placeholder="Date">
</div>
this array should be have atleast one field filled . If all the values are null i don't to submit this form how shoult i validate in request
public function rules()
{
return [
'date.*' => '?'
];
}
I suppose you can try to make sure date is an array with a minimum size and then try to validate the elements of it:
'date' => 'array|min:1',
'date.*' => 'filled',
Laravel 7.x Docs - Validation - Available Rules array
this array should be have atleast one field filled . If all the values are null i don't to submit this form
This will pass
['some date', NULL, NULL, NULL]
This will fail
[NULL, NULL]
This will fail
[]
Anything other than array will fail.
Use a combination of
array, min:1 and a custom rule that checks the null condition.
https://laravel.com/docs/7.x/validation#rule-array
https://laravel.com/docs/7.x/validation#rule-min
https://laravel.com/docs/7.x/validation#custom-validation-rules
public function rules()
{
return [
'date' => ['array', 'min:1', new DateCheck]
];
}
DateCheck rule will check, that there should be at least one element in the array, that is not null.
Inside DateCheck Rule
public function passes($attribute, $value)
{
$dates = $value;
foreach($dates as $date){
if(isset($date)){
return TRUE;
}
}
return FALSE;
}
public function message()
{
return 'There should be at least one date that is not NULL.';
}
