Laravel validation rules if field empty another field required

Question

I have a Laravel 5.3 app, and an update form where I send user profile values. One of them is user image as well, I am creating a hidden input field for it, so if the user is not uploading any new image, I can still see that he has the hidden field with the old image value.

<input type="hidden" class="form-control" name="old_image" value="{{ $player->image_filename }}" id="oldImage">

If he removes the image, the hidden input value becomes empty.

document.getElementById('oldImage').value = '';

That is how I thought of updating a user image. But I don't know how to set up validation rules for that form. Something that would be similar to this:

    public function rules()
    {
        return [
          'first_name' => 'required|max:50',
          'last_name' => 'required|max:50',
          'birthday' => 'required',
          'image' => required if old_image empty
        ];
    }

I have tried with 'image' => 'required_without:old_image', and also with 'image' => 'required_if:old_image, null', but none of them showed any error message for missing image. I am showing error messages like this:

you can use required_if validation rule . refer : laravel.com/docs/5.3/validation — mith

You can work with two rules

'image' => 'required_if:old_image'

Or:

'image' => 'required_without:old_image'

doesnt work anymore : Validation rule required_if requires at least 2 parameters

Foad Tahmasebi Over a year ago

required_if:old_image,null

eithed Over a year ago

Atm (Laravel 8) required_if:x,null isn't the same as required_without:x

For new laravel versions, if you need to use required_if, it requires at least two parameters, so you should use the second and third parameter as if conditions.

  'old_image'=>'required_if:image,=,null',
  'image'=>'required_if:old_image,=,null'

this is can be done by required_without rule, if it's not working please show an actual sample request data ( dd(request()->all() )) and the validation rules you are using. the scenario you want to catch is simple: if both fields is empty.

in your example, applying this rule should work:

return [
          // ...
          'image' => 'required_without:old_image'
        ];

required_without:foo,bar,...

The field under validation must be present and not empty only when any of the other specified fields are not present. Validation - Laravel 5.3

Example:

$rules = [
        'new_value' => 'required_without:old_value'
        ];

validator(
        ['new_value' =>'',
        'old_value' => 'old value is preserved here']
    , $rules)->errors()->toArray();

// output: [] <-- no errors!

validator(
        ['new_value' =>'New value!',
        'old_value' => '']
    , $rules)->errors()->toArray();

// output: [] <-- no errors!

validator(
        ['new_value' =>'',
        'old_value' => '']
    , $rules)->errors()->toArray();

// output: ["new_value" => ["The new value field is required when old value is not present."]]

This should be the accepted answer. Some integrations with Laravel rules require array configuration (such as Folklore GraphQL), and any non-pure validation will not suffice.

You missing nullable validation

'old_image' => 'required'
'image' => 'required_without:old_image|nullable'

I know this is an old question but I came across it during my search. So I'll post my solution here as well for future visitors.

I think this solution is what the OP wants. This solution is not using other packages or custom validation methods so that's a plus as well imo.

What I did was this:

public function rules()
{
    return [
      'first_name' => ['required', 'max:50'],
      'last_name' => ['required', 'max:50'],
      'birthday' => ['required'],
      'old_image' => ['nullable'],
      'image' => [
          Rule::requiredIf(function() {
              return empty($this->request->get('old_image'));
          })
      ]
    ];
}

Try this

if (empty($request->input('old_image'))){
     $this->validate($request, [
       'image' => 'required',
     ]);
}
else {
     // Validation in case of else goes here
     $this->validate($request, [
      // rule
     ]);
}

There's a Laravel wrapper for this; $request->has('old_image')

use Illuminate\Validation\Rule;
'image' => Rule::when($request->image != null, 'required|string')

You will need to use required_with:

'image' => 'required_with:the_other_field_name_here'
