Set value to NULL in MySQL

Question

I want a value to be set to NULL if nothing is put into the text box in the form I\'m submitting. How can I make this happen? I\'ve tried inserting \'NULL

You're probably quoting 'NULL'. NULL is a reserved word in MySQL, and can be inserted/updated without quotes:

INSERT INTO user (name, something_optional) VALUES ("Joe", NULL);
UPDATE user SET something_optional = NULL;
