Promotional Code empty still calls server

[codedsun]

The Apply promo code section while ordering tickets for an event hits the API even when the promocode text field is empty.

To Reproduce

2. Click on apply promocode
3. Click on tick without entering any value -Hits the API

Expected behaviour
Shouldn't hit api and should be handled client side.

@codesun , i want to work on this.

[maze-runnar]

@codedsun so it should validate from client side when promotion code field is empty?

[maze-runnar]

@codedsun , what about this solution -
make the submit promotional code button dissappear when there is not any promotionalCode,and i made frontend validation working too -

make the submit promotional code button dissappear when there is not any promotionalCode

See how it's working for other input fields. This also looks good to me.
