Обсуждение: booleans

Good day all,

I just wrote an HTML form with a PHP script to enter data into a table
witha boolean field.  When I pressed enter it returned the following error
"Warning: PostgresSQL query failed: ERROR: Bad boolean external
representation".  The script is as follows:

if( $id ) {
        pg_Exec($conn, "INSERT into authors
        VALUES ('$pubrelease', '$id', '$first');");
        }

I would appreciate any help.

Thanks,

-Greg

   Postgres supports bool as the SQL3 boolean type. bool can have one of
   only two states: 'true' or 'false'.

Boolean accepts only one of the following values:

   True:  't', TRUE, 't', 'true', 'y', 'yes', '1'
   False: 'f', FALSE, 'f', 'false', 'n', 'no', '0'

- Note that you have to enclose data between '' except for words
TRUE/FALSE.
  Probably you are trying to insert data in a different way.

Initially I was inputing 't' and 'f'.  Then I tried 1 and 0 and it
worked.  PHP3 cannot parse t or f I guess.

Thanks for the info,

Did you echo your query on the page on which you execute it to see exactly
what it looks like when you're trying it with 't' and 'f'??  I'd bet
you're having some problem related to the escaping of quotes.  What is
your magic_quotes_gpc setting?  PHP shouldn't have any problems delivering
this query to Postgres...

I wouldn't think it would have any problem handling this code either,
code I used was :
if( $id ) {
        pg_Exec($conn, "INSERT into authors
        values ('$pubrelease', '$id', '$first');");
        }
First was the variable where the boolean, t or f was to be placed in the
HTML form.  I did not put quotes insert them with quotes for this is
already done with the PHP.  This works for int, text, etc. hich was why I
was surprised by the error message.
