Adding multiple dates at once?

[Strick92]

Hello, I have a table and I want to save multiple dates in it. I can do this with varchar, but it seems like it would be easier to do it with date and fetch it. I added an array to the column that is date (varchar 250) and it contains 4-5 dates. How can I call this when selected with a datepicker? I would appreciate it if anyone has an idea or has done this before and can help. In the past, I have used datepicker coming from POST. If($_POST){ $datepicker = $_POST[$par]; $query = mysqli_query("select * from tables where date"); //date is my date table if(mysql_affected_rows()){ while($row = mysqli_fetch_array($query){ How can I convert the system that works with a single date normally to the system above? Thank you, have a good day.
