Handle conditional validation

[FARUK-YILDIRIM]

What version of this package are you using? 3.22.1

What problem do you want to solve?

I'll try explain case with under below code. I want to retrieve the "birthday" value only when the entityType is INDIVIDUAL. The current implementation works for this case, but I don't need the "birthday" parameter when the entityType is CORPORATE. To handle this, I created an ignore_if rule that ignores the "birthday" field if the entityType is CORPORATE.

const rules = {
    entityType: "required|integer|in:" + `${Object.values(entityType).join(",")}`,
    birthday: [
        "date",
        { required_if: ["entityType", entityType.INDIVIDUAL] },
        { ignore_if: ["entityType", entityType.CORPORATE] },
    ],
};

What do you think is the correct solution to this problem?

The ignore_if rule can be a solution for this case. I solved this problem by adding the following code to the rules.js file.

 ignore_if: function (val, req, attribute) {
   req = this.getParameters();
   if (this.validator._objectPath(this.validator.input, req[0]) === req[1]) {
     delete this.validator.input[attribute];
   }
 },

Are you willing to submit a pull request to implement this change?

Yes, I can
