PHP mysql auto insert timestamp

Question

Say I have a table name auto_parts with these fields. id, part, price, timestamp and I insert a new row via php as so:

$query = \"insert into auto_p         


        

Answer 1

$query = "insert into auto_parts(id, part, price, timestamp)
  values(1, 'axle', 200, 'NOW()')"
mysql_query($query);

Answer 2

Do it in SQL itself instead of passing it ... its more efficient ... This is the corresponding post:

Auto TimeStamp new entry to DB (phpMyAdmin)

Answer 3

What you need to do is declare timestamp to be of type in your sql

timestamp TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

and modify the query to

$query = "insert into auto_parts(id, part, price)
  values(1, 'axle', 200)"
mysql_query($query);

Answer 4

I know there are already answers to this question so I am kind of combining all answers and explaining a little bit. There may be two ways to do this,

1. Change your table and make timestamp column to default CURRENT_TIMESTAMP

ALTER TABLE tablename MODIFY timestamp TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP

and modify your query like this, timestamp will be inserted automatically

$query = "insert into auto_parts(id, part, price) values(1, 'axle', 200)"; mysql_query($query);

2. If you have more than one timestamp table then you can make one as current timestamp and for other one use like this

ALTER TABLE tablename MODIFY timestamp TIMESTAMP NOT NULL

and modify your query like this

$query = "insert into auto_parts(id, part, price, timestamp) values (1, 'axle', 200, now())"; mysql_query($query);
