Question

In my MySQL database, I have a table with structure

username - varchar
insert_time - timestamp

This table was created in MySQL using the phpMyAdmin tool and for the insert_time column, I have mentioned default value as 0000-00-00 00:00:00.

Now the problem is, I have to update this default value with the current timestamp later on, using a PHP script.

I tried doing the following PHP code:

$update_query = 'UPDATE db.tablename SET insert_time=now() '.
                'WHERE username='.$somename;

When the PHP script is run, it fails, and is unable to insert anything into the database.

What am I doing wrong?

Answer 1

What error message are you getting?

I’d guess your actual error is because your php variable isn’t wrapped in quotes. Try this

$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='" .$somename . "'";
