Re: [PHP-DB] Index on email or ID?
Something I used was this: id | username | password | cookie_string $foo = the id was rot13'ed then base64-encoded $str = the cookie_string was an md5 hash generated at the time of registration then a cookie was set: setcookie(cookie_string,$foo.|.$str); When the user returns, we checked for the cookie, and if it existed, split on the |, de-crypted (haha) the ID, looked up the cookie_string in the DB and saw if it matched. If it did, it was pretty unlikely that it was hacked so we logged them in. Peter On Wed, 4 Dec 2002, Jim wrote: Always, always, always use a value that has no other significance other than being a unique ID. Email addresses change and so do passwords, so those are poor choices for linking data. They are fine and good choices for login, but that's about the only thing they should be used for. I understand what your saying, but if I just use the ID, then it makes it extremely easy to login as another user, simply change the ID in your cookie. Atleast if I have email/password aswell it takes someone with access to the network and a sniffer to get the values. If a user changes his email and/or password, then the cookie gets updated, simple. I can't see that its that much of an issue. If we were talking about a credit card number or something else critical then I'd agree.

Hi,
I'm using some form fields on a page to pick up existing data from a MySQL

I've picked up the data ok, now i want to process the update...
How do i call a function(?) on the same page rather than use another page

what i'd like to do (in seudo-code) is:
form action=myfunction()

Re: [PHP-DB] I got this idea...
Another option might be to list out the web sites that have paintball products, and then use google's site: functionality to search fo a product on each site. Store the results in a table or array, and diplay then for the user. So it would work like this: User says find me the MegaBlaster5000. You have a list of 20 sites that carry paintball equipment. Use Google to find MegaBlaster5000 on site1, site2, etc. and store the results in an array. Display the contents of the array to users. Unless you're willing to use a spider to search the other sites on a regular basis, I'd say do it in realtime. Mark --- Ignatius Reilly [EMAIL PROTECTED] wrote: Well, we can only offer very general guidelines at this stage. What you can do is write a script that: - call all the URLs showing paintball prices (btw what is a paintball?) - extract the product name and price. this will require a specific REGEX for each URL called, and regular testing vs change of page design. the only difficult part is just this: writing and testing custom REGEXes.

Thanks for the responses. I chose to use this method as it appears

Get yourself an editor that does syntax highlighting (Vim is very good for
this and is available for most platforms). That way you can see at a glance
whether you have unbalanced quotes (both ' ), and you can easily check for
match brackets (, {, [. You would have to manually check for missing ;
though.

Re: [PHP-DB] MSSQL Problems
mssql_pconnect cannot be closed as you mentioned: http://www.php.he.net/manual/en/function.mssql-pconnect.php I am using this as well, calling MSSQL on a Windows box from PHP/Apache on Linux, and I am also getting some of the results you mentioned, although it behaves differently at different times so I'm sticking with it to tinker. My advice would be to simply drop using mssql_pconnect and use mssql_connect. You don't gain much in the way of speed by using mssql_pconnect and I have seen several people come away with varied results. Your sys admin (or you if you do double duty) should be able to see if this is actually the case through SQL Server Enterprise Manager. It should show the calling server, the PHP version, and that the connections are sleeping.

Re: [PHP-DB] MySQL Array
I think he meant that he is only pulling one column, i.e. field1 with each
mysql_fetch_array and he wants that in four columns.
$c = 1;
echo tr;
while($ar = mysql_fetch_array($result))
{
echo td{$ar['field1']}/td;
if(($c % 4) == 0) { echo /trtr; }
}
You'll have to account for incomplete rows and clean up the output, but
hopefully that gives you an idea.

Make sense?

Subject: [PHP-DB] MySQL Array
Hello,
I am pulling one column out of a MySQL table in an array. I want to place
each element into a HTML table 4 rows across. I am currently doing this
with the mysql_fetch_array() function. How can I pull out 4 array elements
in one pass through a while loop?
Thanks

[PHP-DB] ANNOUNCE: Metastorage object persistence API generator
Hello, Finally I made time to release a full blown application based on MetaL compiler persistence module. Here is the release announcement that may also be found on the site: http://www.meta-language.net/news-2002-12-05-metastorage.html _ Released Metastorage generator Manuel Lemos, 2002-12-05 16:11:44 GMT Metastorage is an application that is capable of generating persistence layer APIs. It takes a component definition defined in the Component Persistence Markup Language (CPML), a XML based format, and generates classes and storage schemas in a given target programming language. Using CPML, developers can focus their efforts on the modeling of data structures that hold the information and the relationships between the entities that their applications deal with. Metastorage takes care of generating all the necessary code to store and retrieve such data structures from persistent storage containers like relational databases. The main goal of Metastorage is to drastically reduce the time to develop applications that traditionally use on SQL based relational databases. The generated APIs consist of a sets of classes that provide an Object Oriented interface to the objects of the classes modeled using CPML. The generated APIs are also capable of installing the data schema in the persistence container, which in the case of a relational database is the set of tables that will hold the persistent objects. This completely eliminates the need to write any SQL queries manually. CPML is independent of the type of persistent container. This means that while it can be used to model classes of persistent objects that may be stored in relational databases, such objects may as well be stored in other types of persistence containers. For instance, if an application needs to move a directory of objects with user information from a relational database to a LDAP server to increase the application scalability, the same CPML component definition would be used. Metastorage would then generate classes objects that implement the same API for interfacing with a LDAP server that is compatible with the API generated to interface with relational databases. This make the migration process easier and with reduced risks. Another possible benefit of the persistence container independence of the APIs generated by Metastorage, is the case where an application may need to run in environments where a SQL based database server is not available. In that case the same API could be generated to store persistent objects in flat file databases or plain XML files. For now, the current version of Metastorage only supports the generation of PHP code based on the database independent Metabase API. This means that it may also interface with PEAR::MDB database abstraction layer using its built-in Metabase API wrapper. In consequence, many types of relational databases are already supported. Since this is the first release of Metastorage, there is plenty of room for improvement in the possibilities of the generated persistence APIs and the level of optimization of the generated code. In the future it will be supported other languages besides PHP, other database APIs besides Metabase and other persistence containers besides relational databases. Metastorage is based on MetaL compiler persistence module. Like MetaL, Metastorage is Open Source and is distributed with BSD like software license. Downloadable archives and documentation with an example of component definition are available from the MetaL site. -- Regards, Manuel Lemos -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] mysql_use_result()
Hi, I was trying to do a simple equal join with two tables (one has more than 2,500,000 records; the other one has more than 34,000 records) on indexed attributes. But it took a long time for MySQL to run the join and eventually it returns a error msg Out of memory... needed 8136 bytes). Then I used mysql --quick to run the same query and it returns the results very fast. My question is: which PHP function can I use to query the MySQL database in the mysql --quick mode? That is which PHP functions represents the mysql_use_result()? Thanks! Qunfeng Dong __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
