[PHP-DB] Cookie problem
Hi,
I'm trying to use PHP to set a cookie to recognize people returning within a month.
However no matter how i use the code, no cookie is being set. I've been in touch with
my host, who assures me that cookies function in the 'normal' way on their servers, so
its probably something wrong with my code. I'm using this:
$time = mktime()+(60*60*24*30);
setcookie('lifevision', $dist_id, $time, '/', 'www.dono.co.uk','0');
i've also tried without the www and without the www. in the domain. To test if the
cookie is being set, the url www.dono.co.uk/testing/ should set a cookie. It also
starts a session for people who can't accept cookies. (i've also put a print_r at the
end of the page to print the cookie contents, if any) However the cookie just isnt
appearing. Any suggestions appreciated,
Don
[PHP-DB] Re: Subject: Cookie problem
First check that you are not sending any content before trying to set the
cookie :
It effectively is sending a header, and headers must be sent before any
other content - even a white space before your PHP script which sets your
cookie will send headers so then your cookie will not be set.
You can check if headers have been sent with the convenient headers_sent()
PHP function, which returns true if headers have already been sent.
That's the most likely diagnosis IME, if everything else checks out.
Cheers - Neil.

[PHP-DB] Re: substr() problems
I don't see anything initially wrong with this statement, but you might try a variation and see what you get. First: condense this: $DB_sub_ref = substr($DB_temp_ref , 0, 1); $DB_sub_ref .= substr($DB_temp_ref , 1, 1); to this: $DB_sub_ref = substr($DB_temp_ref , 0, 2); Your code will run slightly faster... Second change the third line there to: $DB_sub_ref .= substr($DB_temp_ref , -1); That should do the same thing, grab the last character in that string. Try that and see what you get. Jeremy James Meers [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi all, I am trying to use substr() negative start, but I get nothing returned - if i do a positive start then i do get something back, below is my code and a line of what i get returned: $DB_ref = 210020007; $DB_temp_ref = $DB_ref; $DB_sub_ref = substr($DB_temp_ref , 0, 1); $DB_sub_ref .= substr($DB_temp_ref , 1, 1); $DB_sub_ref .= substr($DB_temp_ref , -1, 1); echo $DB_sub_ref - $DB_ref; RESULT: 21 - 210020007 note: 210020007 is an example this is actually within a while statement using mysql_fetch_array from a SQL query - all results are not returning the negative string.

Dear friend,
I changed
$_POST['testField']
instead of

Before it was returning parse error now it doesnt return any error nor writes
to mysql database, however I used following sql staatement which wrote to
database before
// create the SQL statement
$sql = INSERT INTO testTable values ('', '$_POST[testField]');
Now I have added more columns to database and form and made similar changes
in the php script, now it doesnt write with this sql statement to database

Re: [PHP-DB] Rules in a database
If you string-concatenate atomic rules in a field, IMHO you will never
manage to extract any information.
Parsing these strings will be a nightmare.
With the fully normalized model I have in mind, your SQL should be a breeze.
This is quite logical after all: your flattened rules are polynoms of
degree 1 in an arbitrary number of variables; each monome of which is
homéomorphic (?) to a subset of the rule set. This structure matches well
the representation of records in a SQL table as set elements:
- it is easy to check that a given monome exists,
- then it is easy to check that the required monomes have been associated as
a complex rule.

Subject: Re: [PHP-DB] Rules in a database
Thanks for that. I understand you'd have one table with simple phrases
like a=b being atomic rule 1,
c=d being atomic rule 2...e=f being atomic rule 4, say; the second table
with 1,2 as an AND group
rule 1, being the 2 alternative - OR - conditions, one of which must
exist; and the third table with
1-4, stating that AND group rule 1 would lead to result 4. In total, if
1 or 2 is true then e=f.
I think, however, that I might find it easier to combine:
- store AND rule groups in a table (1-n relation to the atomic
table)
- store full rules in a table (1-n relation to the AND table)
into one table column and use string functions to extract the rule. The
first table remains the same,
being a list of a=b rules. The second table might have a record in the
IF field +(12 OR 3) AND (13 OR
4) and 4 in the THEN field..
Looking beyond to the sort of queries I might want to run. If I knew a
condition was true, say
condition 12, I would want to know what possible rules might be relevant
(I think of a rule as an
IF:THEN set). Or if I knew two conditions were true, say 12 and 13, I
would want to know what rules
applied when those two conditions were true. The queries would be: SELECT
full_rule FROM
full_rules_table WHERE INSTR('/12/',IF) - I don't know if that INSTR works
as shown. That would tell
me if the rule might apply. To know whether the rule would actually
apply - is fully qualified - I
need to know if condition 13 - or alternative 4) is also true. I envisage
parsing the expression +(12
OR 3) AND (13 OR 4) into array elements (12 OR 3) and (13 OR 4) and then
going through each and
comparing to the conditions I know exist, then reporting various facets of
the rule, including
alternatives or additional conditions required.
The report would contain information like:
These conditions are true to start with.
The following results follow (since all conditions needed are true)
- the same result would occur in alternative conditions:
..instead of condition 12 condition 3 applied etc
The following results could occur if additional conditions were true:...
- result 1 ...the following extra conditions are requiredetc.
Do you think this is feasible?

John

Subject: Re: [PHP-DB] Rules in a database
A bit of algebra first:
any expression formed of atomic expressions, AND, OR and parentheses can
be
reduced to a canonical form, by using the De Morgan laws:
a AND ( b OR c ) is equiv. to a AND b OR a AND c
So a rule can eventually be reduced to AND groups, joined by OR:
a(1) AND... AND a(n) OR ... OR z(1) AND ... AND z(p)
Each AND group contains 1 or more rules.
Therefore, to model input rules:
- store atomic rules in a table
- store AND rule groups in a table (1-n relation to the atomic
table)
- store full rules in a table (1-n relation to the AND table)
Now you can model output rules likewise, and finally create a table of
associations between input and output rules
Problem is: once you've flattened your rules to the canonical form, they
can
become illegible. So perhaps a hierarchical data model (XML) would be
more
appropriate, for your rules would remain human-legible (and thererfore
human-maintainable)

Re: [PHP-DB] FW: db design - which is better
Hmmm... What of maintenance? One day your pointed-headed boss asks you to add a civility field (Mr|Mrs|Colonel|...), a birthdate, etc. How do you do that with a 1-table design? You will have to create 1-NF temporary tables in the process... How do you search for an author? You will have to create a needlessly large and inefficient index on (LastName + FirstName), instead of a nice integer index. And when querying the articleID, I do not think that there should be a significant performance penalty, if your indexes are properly designed. cheers Ignatius _ - Original Message - From: mayo [EMAIL PROTECTED] To: php-db [EMAIL PROTECTED] Sent: Sunday, February 08, 2004 00:10 Subject: RE: [PHP-DB] FW: db design - which is better Let's say you have a page that is hit fairly frequently and spits out 100s of results.

You will have to create 1-NF temporary tables in the process... How do you search for an author? You will have to create a needlessly large and inefficient index on (LastName + FirstName), instead of a nice integer index.

[PHP-DB] Re: Form doesnt write to database
Dear friends,
Form doesn't write to mysql database. I have pasted code of mysal
table structure,html form and php script. Any comments, please.
// create the SQL statement
$sql = INSERT INTO testtable values ('{'', $_POST['testField']}','
{'', $_POST['testFielda']}','{'', $_POST['testFieldb']}','{'',
$_POST['testFieldd']}','
{'', $_POST['testFieldc']}','{'', $_POST['testFielde']}');
I tried your code on my system and got an error of 'incorrect number of
parameters'. That's when I realized you need NULL as the first
parameter in your values. I didn't see in the MySQL docs where it
requires the NULL, but in one of the examples, it was there.
Insert NULL as the first parameter and it should work.
I also got a parse error because of the '{' and '}' symbols around your
$_POST variables. I changed it to:
$sql = INSERT INTO testtable values ( NULL, '.$_POST['testField'].',
'.$_POST['testFielda'].', '.$_POST['testFieldb'].',
'.$_POST['testFieldd'].', '.$_POST['testFieldc'].',
'.$_POST['testFielde'].' );
and got a working solution.
Suggestion: You could try using the mysql_errno() and mysql_error()
functions. Print them out after your failed statement and you'll see
why the mysql call failed.
Example:
print Error # .mysql_errno(). - .mysql_error().BR\n;
will print the error number and message. This will give you some idea
of what went wrong.
Good coding practice dictates that you check for an error condition
after mysql calls [using mysql_errno()] and handle any errors
appropriately.
If you don't already have it, you'll want a list of the error codes and
their meanings. You can find it in the mysql source code
Docs/mysqld_error.txt file. If you can't find that right now, copy this
web page I whipped up right now:
http://web.netmask.com/2004/02/mysql-error-codes.html
or, if you prefer a flat, text file:
http://web.netmask.com/2004/02/mysql-error-codes.txt
Good luck!

[PHP-DB] Re: php-db Digest 8 Feb 2004 01:40:01 -0000 Issue 2250
Hi, I want to grab a value from one table field and place another value in another table fied. So If I had table value1 and it was set to 3 I want to recognise the value 3 and put value 1 in table value2. Example: value1: 3 value2: (blank) So now I need to check value1 and MAKE SURE 3 is the value, if a lower value I want to do nothing. If 3 than I want to use the value Example 2: value1: 0 (grab 3 and reset to 0, if higher than 3 do the same) value2: 1 (If value1 is 3 than value 1 needs to go in value2) But how can I achieve this? The queries are ran once a day, no more. So when the query is ran I could than execute the second query to change the value#'s. Would I be right in saying that I'd use a 'IF statement' for this? Or is there another way to do this? I am not sure exactly about executing a query with the IF statement, I do know how to execute a message or HTML information to output to the webpage. I've done some reading online, but have not found what I am requiring ... Could be looking in the wrong place, as usual. All help appreciated. Jerry http://greetings.yahoo.com.au - Yahoo!

Re: [PHP-DB] FW: db design - which is better
There just seems to be times when non-normalized table structures are easier to work with. There are times when de-normalizing is acceptable. One of the more common uses of denormalized data is in data warehousing. Such as pre-summing sales, and storing pre-calculated aggregate information to relieve the db of doing heavy or complex calculations when summary data is going to be queried on a frequent basis. Often php-based message boards will use columns of pre-sumed data as part of a normal table (for example, a count of total user posts stored in the user table, that is incremented/decremented when a user adds/deletes a post, or the total number posts in a given thread stored in the topic table). This helps to allieviate the need for a count() whenever a message thread is built and you want to show the number of posts each user in the thread has, etc. So there are some acceptable situations :) Cheers, Keith. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hello Again: Another release of PEAR DB was made yesterday, 1.6.0RC5. The most important change was fixing the bug for people who use arrays for the DSN information when connecting. It also adds a new method called quoteIdentifier(), which is used for delimiting identifiers (such as field names and table names). I'm planning to issue the stable 1.6.0 release on Tuesday. So, please download the package and test it out. File bug reports if stuff doesn't work or is unclear.
