'text' => NULL,
),
15 =>
array (
'value' => 'value_per_conversion',
'text' => NULL,
),
),
)
I am validating this data like this:
$validator = Validator::make($request->all(), [
'name' => 'required',
'import_period' => 'required',
'google_ads_account' => 'required',
'period' => 'required',
'period_date_from' => 'required_if:period,custom',
'period_date_to' => 'required_if:period,custom',
'id_campaigns.*.id_campaign'=> 'required',
'id_adgroups.*.id_adgroup' => 'required',
'campaign_name_contains' => 'required',
'adgroup_name_contains' => 'required',
'mapping_list.*.text' => 'required|min:1',
'click' => 'required',
'click_value' => 'required_if:click,greater_than,less_than',
'click_from' => 'required_if:click,between',
'click_to' => 'required_if:click,between',
'cost' => 'required',
'cost_value' => 'required_if:cost,greater_than,less_than',
'cost_from' => 'required_if:cost,between',
'cost_to' => 'required_if:cost,between',
'impressions' => 'required',
'impressions_value' => 'required_if:impressions,greater_than,less_than',
'impressions_from' => 'required_if:impressions,between',
'impressions_to' => 'required_if:impressions,between',
'conversions' => 'required',
'conversions_value' => 'required_if:conversions,greater_than,less_than',
'conversions_from' => 'required_if:conversions,between',
'conversions_to' => 'required_if:conversions,between',
]);
Here on this line 'mapping_list.*.text' => 'required|min:1' I am trying to validate this mapping_list array.
I want at least one field should be filled up but I have to fill up every element of this array.
Can you tell me is there anyting I am doing wrong?

Answer 1

If you want to validate that at least one field is filled, you must specify which field you want to validate. For example (in your code):
'mapping_list.*.text' => 'required|min:1',
you can change
'mapping_list.[0].text' => 'required|min:1',
or
'mapping_list.[1].text' => 'required|min:1',
That should be all you need to do. Hopefully that helps!
