Re: [PHP-DB] Modify MySQL Record
When you have an auntoincremente field inyour table, you don't have toespecify the field name in the query,as the following:
$query = "INSERT INTO cnrl_db (kwo, lsd, date, well, field, uni,
license, formation, perfs, event, fluid, mode, type, vhd, file, kb, grd,
open, sour, tube, landed, casing, landed2, shut_date, shut_time, pres, tag)
VALUES ('$kwo', '$lsd', '$date', '$well', '$field', '$uni',
'$license', '$formation', '$perfs', '$event', '$fluid', '$mode', '$type',
'$vhd', '$file', '$kb', '$grd', '$open', '$sour', '$tube', '$landed',
'$casing', '$landed2', '$shut_date', '$shut_time', '$pres', '$tag')";
hope it helps

Ok, so I added what you suggested, but it still doesn't assign any numbers
to the records.
$query = "INSERT INTO cnrl_db (gradient, kwo, lsd, date, well, field, uni,
license, formation, perfs, event, fluid, mode, type, vhd, file, kb, grd,

$result = mysql_query($query, $link_id) OR die(mysql_error());

Jeff,
When you want to increment an autoincrement field, you just put NULL into
the query. For example:
INSERT (NULL,'Jeff','php list','Modify MySQL Record') INTO mail;
Where NULL is in the same spot in the field list as your autoincrement
field.
That concept is covered in the MySQL manual. Pretty simple stuff. If
you're
in a situation where you have an autoincrement field that you sometimes
autoincrement and sometimes manually assign a value to, I think you're
misusing the autoincrement field (IMHO). If you have that situation, use
the
autoincrement field to assign a unique ID to the table row and use a
separate field with another name for the manually assigned data.
As far as the stuff you mentioned about clicking things and getting the
messages you expected, I'm kinda' lost. But if you use the autoincrement
field as it is intended, the logic should present itself.

Ok, so it sorta works now *grin*
Two new problems
I added an auto increment field in my table and changed the
php to reflect
that field - But for some reason, it doesn't work..
When I submit a new record, do I need to tell SQL to add one to the
greatest, or should it do it automatically when a new record
is created?
gradient MEDIUMINT(10) DEFAULT '0' NOT NULL AUTO_INCREMENT,
and I made it the primary.
Problem two,
If I manually enter a number into that field, I can make
changes to the
record no problem! but... it goes into some kind of
continuous loop. It
comes up with a window that says what I told it to say --
user_message("All
records regarding $kwo have been changed!",
"$PHP_SELF?action="" --
I hit OK and it jumps to -- if(empty($kwo)) error_message('Empty
Gradient!!'); -- if you hit ok again, it just loops.
This might be solved as soon as I get that one field to auto
populate. :P

Jeff,
No problem. Happens to everyone, trust me.
Anyway, I see you're using mysql_affected_rows($link_id) to
get see how
many
rows were affected by the UPDATE. Try getting rid of the
$link_id in the
declaration and just use mysql_affected_rows(). Personally,
I have always
had trouble when specifying a resource in a mysql function
like this (it's
probably just me). But, the mysql_affected_rows() function will, by
default,
use the last connection used by your script.
Also, you're checking to see if it's not set e.g.,:
$num_rows = mysql_affected_rows($link_id);
if(!$num_rows) error_message("Nothing changed!");
According to the documentation, mysql_affected_rows()
returns a -1 if the
query failed. And I'm pretty sure it returns 0 if your query was
successful
but didn't affect any rows. I'm pretty sure ! checks for
FALSE which is
not
one of mysql_affected_rows() valid return values. So your
check isn't
doing
what you think it should.
Give that a shot and see if it helps out at all.
Good luck.

RE: [PHP-DB] Modify MySQL Record
That's ok Richard,I posted the message'cause i haven't seen yours.
As a matter of fact. I'm really new to MySQL, my DB background is MSSQL, so, in the MSSQLBooks Online I found this:
A. Use the IDENTITY property with CREATE TABLE
This example creates a new table using the IDENTITY property for an automatically incrementing identification number.USE pubs
IF EXISTS(SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'new_employees')
DROP TABLE new_employees
GO
CREATE TABLE new_employees
(
id_num int IDENTITY(1,1),
fname varchar (20),
minit char(1),
lname varchar(30)
)
INSERT new_employees
(fname, minit, lname)
VALUES
('Karin', 'F', 'Josephs')
INSERT new_employees
(fname, minit, lname)
VALUES
('Pirkko', 'O', 'Koskitalo')
The only one thing i have to do was to try it in MySQL and fortunately it works.
Anyway, Jeff have 2 options to select, right?...

Yup, Fernando is correct. But it is not incorrect to specify a NULL value in
your query for an autoincrement column. Right out of the MySQL manual:
"If you insert NULL into an AUTO_INCREMENT column, the next number in the
sequence is inserted."
Although the MySQL manual implies it by giving examples where rows are
inserted into tables with an autoincrement column, I could not find a spot
where it explicitly states that you don't have to provide a value for that
column in an INSERT query.
Probably just falls into the personal preference category.
