Why is one of the input values not received?

The front-end framework is mini UI, and the input has already obtained the data. Why can't php receive the data? Other inputs can be received. Please, O (∩ _ ∩) O thank you ~ I can get it by entering it directly in the input of the exchange unit. it is clearly written into. what is the difference?

Does your input element have the name attribute ?? It cannot be accepted without a name.
