RE: [PHP-DB] Can't Insert more than 1 record
Hello All, I am having a problem inserting records into my Database. I am passing fields from a FORM to my php program that adds 1 record to my DB. It will create the first attempt just fine, however any attempt after the 1st fails. I have to delete the existing row in order to add a new record. Anyone know what I am doing incorrectl? KJ Do you have unique indexes on your table? On each insert are you sure that the unique index columns are actually unique? What errors do you get on the second++ inserts?

RE: [PHP-DB] PHP script execution - display issue
Hello, I have a display problem with one of my sites. Because there is an big amount of information in the pages, which is extracted from database, using IE browser I see only the background of the site, and then, after a time, the whole page. My client has recently requested to make something to improve the site speed and display time. So because all the site is done using the classes, and the information is extracted through them, I reduced the instruction numbers, and I compacted as much as I could the classes. But I still have the display problem using IE browser : I see the background, and just after that I see the whole site. I mention that the classes are included, and the class function is called through $this_class-function($parameters); Not all the classes used in the page are called In the beginning; and another mention is that the site pages contains 4 sections. Top, left, middle, right. My question is: Is there a way to display sequentially the site. After the background, to display the first section (top), then left part, middle part and right part after that ? Again, the site loads like this : the background, then the whole page. This doesn't matter if I use dial-up or T1. My client saw, for example, that cnn or yahoo site loads sequentially. Knowing that yahoo is done in php, I'm wondering how they did it.

RE: [PHP-DB] Real Killer App!
I'm having a heck of a time trying to write a little web crawler for my intranet. I've got everything functionally working it seems like, but there is a very strange problem I can't nail down. If I put in an entry and start the crawler it goes great through the first loop. It gets the url, gets the page info, puts it in the database, and then parses all of the links out and puts them raw into the database. On the second loop it picks up all the new stuff and does the same thing. By the time the second loop is completed I'll have just over 300 items in the database. On the third loop is where the problem starts. Once it gets into the third loop, it starts to slow down a lot. Then, after a while, if I'm running from the command line, it'll just go to a command prompt. If I'm running in a browser, it returns a document contains no data error. This is with php 4.3.1 on a win2000 server. Haven't tried it on a linux box yet, but I'd rather run it on the windows server since it's bigger and has plenty of cpu, memory, and raid space. It's almost like the thing is getting confused when it starts to get more than 300 entries in the database. Any ideas out there as to what would cause this kind of problem? Nick Can you post some code? Are your script timeouts set appropriately? Does memory/CPU useage increase dramatically or are there any other symptoms of where it is choking...? What DB is it updating? What does the database tell you is happening when it starts choking? What do debug messages tell you wrt finding the bottleneck? Does it happen always no matter what start point is used? Are you using recursive functions?

Subject: [PHP-DB] Session variables when global variables switched off
[Sorry, first message accidentally fired off to quickly ]
[sorry for the incomplete posting of a couple moments ago. I hit ctl
something or other and outlook fired off the e-mail against my wishes!]
I am making a section on a web site which requires that visitors log-in.
Log-in, password, etc are in an MySQL table. I am using (via a
web host) PHP
4.2.2 with global variables turned off. Until now, I have worked with a
different host in which global variables were switched on.
The way it works
The user logs in at index.php. When she does so successfully, index.php
returns a menu of links. However, if she clicks on any of those
links, which
are different pages, she gets a please log-in first message because each
page includes...
if ($_SESSION['verified'] yes){
echo Pa href='index.php'Please log in first/a/P;
exit();
}
Returning to index.php requires a log-in again.
So, it seems the session variable is not being sent being sent between
pages, although it works within the same page. I expect I am missing
something obvious. I've made this kind of thing work with global variables
on - so I assume I am misunderstanding something related to lack of global
variables.
I use
session_start();
at the top of all pages and
session_register($_SESSION['okbabe']);
on index.php.
Your enlightenment will be highly appreciated.

Subject: [PHP-DB] Data won't insert
I've learned the basics of PHP and MySQL by using a web hosting service over
the past few weeks. Call this site 1. And I am finally feeling that I am
getting the hang of things.
Now, another web host that I have been using is letting me try out PHP and
MySQL on their server. Call this site 2.
The problem I am having is that if I take pages with php scripts from site
1; change the user, password and database names; and upload them to site 2 -
data does not insert into tables. However, the scripts are connecting to the
database (no die messages or other error messages are appearing) and the
tables have been prepared via phpmyadmin without problem. Likewise, I can
insert data via phpmyadmin without problem.
Below is a sample script that is causing such a problem. I appreciate that
it is sloppy (it was one of my first). But it works on site 1 and not site
2. Could this be a matter of the permissions the site 2 web host has
granted me? And if so, why can I do things with phpmyadmin but not via my
own scripts?
Many thanks,
