I have an insert script with mySQL. I need to place the date and time when the record is created in the \'add_time\" column.
Can anyone show me how to modify my existin
You do not need to insert data to that column from PHP at all:
TIMESTAMP and DATETIME columns can be automatically initializated and updated to the current date and time (that is, the current timestamp).
So change the add_time column definition to
add_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP
and then it will automatically populate the column for you when you insert a new row
See: MySql Manual on Timestamp Initializations
