Conditional Validation Issue with mimes Rule in Laravel for Different File Uploads

Hello,

I'm currently facing an issue with conditional validation in Laravel when using the mimes rule. Here's the problem:

I have two fields in my form: company_tin_number and company_tin_certificate. The validation rules for these fields should vary based on the company_type selected by the user.

For company_tin_number, it should be required when company_type is "partnership," "limited," or "others," and it should have a maximum length of 50 characters. This part is working correctly.

However, for company_tin_certificate, I want it to be required and validated as a PDF file (with a maximum size of 7000 KB) only when the company_type matches the specified values. The problem I'm encountering is that the mimes rule is being triggered even when company_type doesn't match the conditions, resulting in an error message that says, "company_tin_certificate must be a file of type: pdf."

Here's my current validation rule for company_tin_certificate:

'company_tin_certificate' => 'required_if:company_type,partnership,limited,others|mimes:pdf|max:7000',

Is there a way to conditionally apply the mimes rule based on the company_type? Any insights or suggestions on how to resolve this issue would be greatly appreciated.

Thank you!
