[PHP] frustrating problem
I hope that I can explain this problem in a logical and clear way. In MySQL, I have two tables for information:: foo, which contains FooID, FooLName, FooFName and foocontact, which contains FooID, FooContactID, FooEmail, FooPhone, FooAddress1, etc. Honestly, I can't remember why I split up the names and contact info into two separate tables, but that's the way it is... In the first hundred or so entries of foocontact, FooID and FooContactID are identical (both columns are auto-increment). But because I've occasionally had problems loading data into the database, and have had to reload some entries while delete or forgetting to delete others, the numbers are now out of synch. For some entries, that doesn't seem to be a problem (I might have fixed them by hand at an earlier date, but I can't remember), but for others, it might be. That may not matter, though. What I'd like to do is call up info from both foo and foocontact using only the FooID, which is passed in the url. I can't understand, though, why the where clause in the folllowing line isn't working the way I want it to: SELECT FooLName, FooPhone, FooEmail FROM foo, foocontact WHERE foocontact.FooID=$FooID and foo.FooID=$FooID; I've also tried: WHERE foocontact.FooID=$FooID and foo.FooID=foocontact.FooID; any idea why that doesn't work? does any of this make sense? sorry if it doesn't, and thanks in advance for your help.

[PHP] what is http://127.0.0.1?
ever since I put up a personal firewall, when I start MySQL I''ve been getting alerts that MySQL is trying to access this ip address when I start it... what, exactly, is it, and is there any reason why MySQL would need to access the internet if I have apache on my own machine? thanks, Matt - Original Message - From: Jadiel Flores [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, July 26, 2002 6:33 PM Subject: Re: [PHP] Installed PHP on home Win98se, now how can I get browser to see it? Obiously you need a WebServer too, you can install Apache or Personal Web Server, and configure php to work with it, next you can browse you own server with the address http://localhost or http://127.0.0.1, maybe you will have to install mysql for windows too if you wanna work with databases too.

Re: [PHP] sessions
re php info:
put this into a file, put it on your server, and call up the page in a
browser:
?php
phpinfo();
?
it will show the settings for php on your server. As Jim suggested below,
you should check the register_globals setting. If register_globals is on,
you'll need to use the _Get function. see more on this by looking up
register_globals and _Get in the php manual at php.net

Sorry, pretty new to all of this.
Do you have register globals off?

Subject: [PHP] sessions
I used this logout page using sessions a while ago and it used to work
great, but now it doesn't work. The only thing i have changed is my
version
of php. Can someone take a look and see what i have to change?
?
session_start();
$old_user = $valid_user;
$result = session_unregister(valid_user);
session_destroy();
?
then a little further down i have this
php?
if (!empty($old_user)) {
if ($result) {
echo Logged out.br;
} else {
echo Could not log you out.br;
}
} else {
echo You have not logged in; therefore, you cannot logout.br;
}
?
It seems to log me out still, but it always gives me the you have not
logged in; therefor, you cannot logout message. i also checked it
with
a
script to see if my original sessions were actually registering and it
seemed that they were. i am stumped. Any ideas would be greatly
appreciated.
Thanks.

[PHP] Re: arrays, variables, and register_globals--solved--thank you
Thank you very much, David--you understood the problem exactly and your solution worked perfectly! I'd like to add a comment about mysql_data_seek to the php manual entry on mysql_fetch_row, because I would think that this might be a common problem... Matt - Original Message - From: David Robley [EMAIL PROTECTED] To: GOLD, MATTHEW [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Thursday, July 25, 2002 5:37 AM Subject: RE: [PHP-DB] Re: arrays, variables, and register_globals So what you want to do is print a field from the first row extracted from the table, then loop through all the rows and print several fields? I think you want mysql_data_seek. Whenever you do a mysql_fetch_row, php grabs the current row from the result set, and shifts a pointer to the next record in the result set. In this case it seems you need to print from the first record, then reset the pointer to the first record and print from all records found. So: $row = mysql_fetch_row ($result)) print ($row[4]); mysql_data_seek($result, 0); // Add this while ($row = mysql_fetch_row ($result)) Unless I misunderstand what you are trying to do Cheers -- David Robley Temporary Kiwi!

Re: [PHP] How come this will echo No or nothing?
this is from the O'Reilly _Programming PHP_ (Rasmus Lerdorf Kevin Tatroe):
Because echo is not a true function, you can't use it as part of a larger
expression:
// parse error
if (echo(test)) {
echo(it worked!;
}
Such errors are easily remedied, though, by using the print() or printf()
functions.
p. 76
Here's how I solved a similar problem:
if ( $foo != '' ) print ( yes);
and then just add the else statement...
best,
Matt

Subject: RE: [PHP] How come this will echo No or nothing?
I've come up with this before and solved it like this (guess it'll
work):
if($row['plevel'] == '0'){
echo 'No';
} else if($row['plevel'] != '0'){
echo 'Yes';
}
Notice the *ELSE IF* instead of a simple else statement. Try it.

Subject: [PHP] How come this will echo No or nothing?
here is the portion of the script:
if($row['plevel'] == '0'){
echo 'No';
} else {
echo 'Yes';
}
here is my table structure dump:
#
# Table structure for table `docs`
#
CREATE TABLE docs (
id int(11) unsigned NOT NULL auto_increment,
name varchar(200) NOT NULL default '',
note varchar(200) NOT NULL default '',
author varchar(200) NOT NULL default '',
path varchar(200) NOT NULL default '',
plevel tinyint(3) NOT NULL default '0',
type char(3) NOT NULL default '',
cat tinyint(3) NOT NULL default '0',
file_size int(11) unsigned NOT NULL default '0',
date int(11) unsigned NOT NULL default '0',
PRIMARY KEY (id)
) TYPE=MyISAM;
the row plevel is either 0 or 1.
why won't this script echo Yes?
The reason that the plevel is set in numbers is because I may add
higher
ones later.

[PHP] is_null question
Hi Everyone,
Here's my problem: I'd like to make the printing of some text dependent on
whether or not a variable is null. In the following example, when $row[1]
is null, what gets printed on the page is Email: . I'd like the
script to not print Email: if row[1] is null.
It looks like I should be using is_null(), but I'm not sure how to use it,
especially since all of this is embedded in a print statement.
while ($row = mysql_fetch_row ($result))
{
print (\ttr bgcolor=\#ff9900\\n\t\tth$row[0]/th\n/tr\n\ttr
class=\default\ bgcolor=\#ff\\n\t\ttdp$row[10]/ppEmail: a
href=\mailto:$row[1]\;$row[1]/abr /Phone: $row[2]/p\n\npAddress:
$row[3]br /$row[4]br /$row[5] $row[6] $row[7]/p pURL: a
href=\$row[8]\ target=\_blank\$row[8]/a/p/td/tr);
}
Instead of just printing Email: $row[1], I'd like to test whether it's null
first--maybe something like this?
if (is_null($row[1])) print else print (Email: $row[0])
but can I put that line inside of another print statement? if so, do I have
to escape the quotation marks? Please forgive my confusion--I'm new to
programming in general and PHP in particular.
Thanks in advance for your help.
best,
Matt

Re: [PHP] Re: Development Tools
The difference between Dreamweaver and Homesite is that Homesite is easier to customize, and it doesn't mess with your code the way that Dreamweaver does. If you're happy with Dreamweaver, you should stick with it. But if you want more control over your code, you should consider switching. Of course, Macromedia recently bought Allaire, so who knows what the next version of Homesite will look like...

Re: [PHP] how to resort results of a query
Thanks very much for your response, Chris--it sounds like that's exactly what I need to do. I'm sorry to trouble you further, but if you have a second, can you give me some advice on how to store results in a temporary table with the columns indexed? I'm very new to PHP, and I'm not sure how to go about it. Thanks in advance. best, Matt - Original Message - From: Chris Hewitt [EMAIL PROTECTED] To: Matthew K. Gold [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Friday, July 05, 2002 7:34 AM Subject: Re: [PHP] how to resort results of a query Matthew, Its a new query unless you want to sort using php routines. For a small amount of data this is fine but for large amounts there is a performance hit. Your choice as to the balance with the amount of data you have. Where I have a lot of data, extracted from a very large amount of data, I store my results in a new, temporary, table that has each field indexed. I make the column headings on my html page into links that extract the data from the temporary table, ordered by that column. As its multi-user, I have a field in the temporary table with the username so that each user gets their own data (its first part of the indices too). Hope this helps Chris Matthew K.
