验证字段：required_if url包含Laravel中的参数

Question

Is there any way to validate required field when the requested url contains some parameter?

Answer 1

Assuming you are using Form requsts, you can simple use PHP condition.

public function rules()
{
    $rules = []; // here you put some rules

    // here you check condition and add some rule when it's true
    if (str_contains($this->input('url'), 'something')) {
       $rules['some_other_field'] = 'required';

    }

    return $rules;
}
