An error occurred during database statement execution

Question

An error occurred when the database executed this statement:

insert into liuyan (title,content,id) values ​​('$title','$content','$_SESSION[id]');

Error: #1366 - Incorrect integer value: '$_SESSION[id]' for column 'id' at row 1

How can I modify the statement or database to solve this problem?

Answer 1

The ID of your data inventory is auto-incremented. If you pass it in yourself, please make sure it is unique and an int type number. You can try it without passing the ID.
