Update mysql timestamp

Question

I have a table with a field:

'last_modified - timestamp NOT NULL'

• I set the default value to the current timestamp. However this only works when updating or inserting from phpMyAdmin and not from my script.

I have tried

$sql = sprintf("UPDATE %s SET timestamp=now(), %s WHERE id='%s'", $table, $implodeArray, $_POST['id']);

and it still doesnt seem to work. How can I make the timestamp update when I update or insert by table from a script?

Also heres a sample of the scripts output:

UPDATE about SET timestamp=now(), page_header = 'Page header goes here', sub_header = 'Sub header goes here', content_short = 'This is where a short description of the about page goes', content = 'This is where the full content description goes' WHERE id='1'

Answer 1

May be I misread,but your column name is last_modified (typed timestamp), so the query should be:

UPDATE about SET last_modified=now(), 
page_header = 'Page header goes here', 
sub_header = 'Sub header goes here', 
content_short = 'This is where a short description of the about page goes', 
content = 'This is where the full content description goes' 
WHERE id='1'
