Backend firebstore validation approve forms?

how can I make any one send a form data from Ionic to firebase database a form content name phone email select options and Main image and a 4 album Image and it will be under approved and when i accept this form data I can show it in the app ? its like some normal classifieds app

What is the reason for phrasing the question without formatting and putting almost all the content in one sentence and not saying what you have done what the error is and not sharing any code, nor the output of ionic info in the posting so at least it is not so difficult to understand how people can help?


i want to send a form inputs to firebase to be under approved from admin to accepted/decline data that will show in the app
