Develop my website's functions -- 2

I have a website running on AWS and i need to fix or develop two things: 1, every week, there should be a button embedded with a survey url link showing up on the user's normal webpage. However, the url link is wrong now. The link is embedding last week's url 2, For the user's normal webpage: right now if the user uses the website and click submit button, there is a date sent to my database, but I want this: if the person does not use the website or does not click the submit button, there is still a date sent to the database without any data shown. Just the date.
