[MySQL/PHP Math Problem - Greater than or less than $variable problem.]

So i'm assuming the 'newtotal' goes gets lower as the 'total' gets higher
and from you're first example.....10 is the highest...newtotal will ever get

so make $newtotal start at 10
and decrement it gradually


[code=php:0]
$newtotal = 10;
if ($total > 15)
    $newtotal -= 5;
if($total > 21)
    $newtotal -= 5;

echo $newtotal;
[/code]

Yes....
genious....it worked perfect
thanks

question....if I had used inner join, right join, or just join
would it had made any difference

[morph to a foreign key]

I hate asking for code but what would that look like
I knew I'd have to use a combination of UPDATE and SELECT but I couldn't get the syntax right

when I first tried it..I got the error
that there was more than one row returned.
a query like this
UPDATE course2 a SET curr = (SELECT b.id from curriculums b where b.prefix = a.curr)

["mysql_num_rows(): supplied argument..." common error]

that's not true
people do it all the time.

[quote=From MySQL documentation]
The index can also be used even if the ORDER BY does not match the index exactly, as long as all of the unused portions of the index and all the extra ORDER BY columns are constants in the WHERE clause. The following queries use the index to resolve the ORDER BY part
SELECT * FROM t1
  ORDER BY key_part1,key_part2,... ;
   
SELECT * FROM t1
  WHERE key_part1=constant
  ORDER BY key_part2;
   
SELECT * FROM t1
  ORDER BY key_part1 DESC, key_part2 DESC;
   
SELECT * FROM t1
  WHERE key_part1=1
  ORDER BY key_part1 DESC, key_part2 DESC;

["mysql_num_rows(): supplied argument..." common error]

If you look at your query you'll notice $id is empty
that's your problem

[quote]FROM playerlist WHERE id= ORDER[/quote]

have you made sure you put the value in the URL.
I notice you're taking it from $_GET
so make sure in your URL your saying
yourplace.com/thisphppage.php?id=7

or something like that

["mysql_num_rows(): supplied argument..." common error]

tell me what this gives you
[code]$result = mysql_query($sql) or die("SQL Query: {wordwrap($sql)}br />Error because:  " . mysql_error());[/code]

["mysql_num_rows(): supplied argument..." common error]

you need to post the error it's giving you

on the $result line
put

$result = mysql_query($sql) or die("Error because:  " . mysql_error());

[Best way to edit your PHP code???]

I use Zend Studio...
it automatically closes your brackets for you, and keeps up with all your variables and functions/classes
so while you're typing it gives you suggestions.

It also doesn't work off Your PHP installation, it has it's own PHP parser, and you can choose between either php4 or php5
a really useful program

maybe someone's caught on by now, but I can't figure how I would do this;

I want to create new field in courses.....easy
go through every record's coursenum field...add the corresponding curriculum id to the new field leaving just the numbers.....WHAT how..

I'm clueless here....
anyone have any advice or suggestions...I know I could make a PHP script to do this, with an array
but that would take quite a bit of processing power

My goal is to get it to look like this
[code]

[Is there an 'OR' statement in PHP?]

I don't know exactly why you're DROP statement fails, but I'm almost sure that users is reserved somewhere in MySQL, maybe if you put backticks around it it would work, but nevermind that way anyway..

It's better to use the IF EXISTS method...example


[code]
DROP TABLE IF EXISTS `my_users`;
CREATE TABLE IF NOT EXISTS `my_user` (
......blah-blah-blah[/code]


[quote]And what about the fact that mysql_select_db does take 2 arguments?  You only show one in your code.  Is this correct?  Thanks zanus![/quote]

[quote]Description
bool mysql_select_db ( string database_name [, resource link_identifier] )
[color=green]Notice the second argument is in brackets.
In most all programming syntax manuals, brackets mean optional.[/color]


Sets the current active database on the server that's associated with the specified link identifier. Every subsequent call to mysql_query() will be made on the active database.
Parameters

database_name

    The name of the database that is to be selected.
link_identifier

    The MySQL connection. [b]If the link identifier is not specified, the last link opened by mysql_connect() is assumed.[/b] If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning is generated.[/quote]

Probably the most asked question there is.
yes it's your SQL query

http://www.phpfreaks.com/forums/index.php/topic,95376.0.html

You need to switch your ORDER by and WHERE in your query

i.e
the Where condition should come before ORDER

[Is there an 'OR' statement in PHP?]

[quote]What purpose does the variable '$connection' serve?[/quote]
You're right on one note....
theoretically you don't have to assign the connection to a variable
once you initialize the function it does it's thing and connects like you want, which is all you want at that point.

But then you might want to error check.
when you run mysql_connect();
it will try to connect and if it does it....for the sake of less explanation..........it doesn't return FALSE.

that way later you can check your variable to make sure it's not FALSE to make sure you actually connected.



Also, suppose you had multiple MySQL servers.
I've never seen anyone do it, but you can assign a connection to a multiple variables....
that way you can say
select database A on this Server
and then select database Y on another Server.
otherwise, whenever you try to select a database with
mysql_select_db()
it just uses the default connection, or the ONLY connection you've made

[Is there an 'OR' statement in PHP?]

you STRINGified the rest of your code and exited PHP at the same time, that's why it doesn't work

look here
[quote]
<?php
//opens a new file and writes the database connection string to it then closes this new file
$connectfile = fopen("dbconnect.php","w");
fwrite($connectfile, [size=16pt]"[/size] [b]<-- You forgot to close your quote[/b]
<?php \$dbh=mysql_connect (\"$serverurl\", \"$nameofuser\", \"$passofuser\")
or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db (\"$databasename\");?>[size=16pt]"[/size]); <--So it thinks this is the end of the string I.E. your argument for fwrite
[/quote]

and also you, for some reason opened another PHP tag (labeled in green above)

change that snippet to this and you should be fine

[code=php:0]
<?php
//opens a new file and writes the database connection string to it then closes this new file
$connectfile = fopen("dbconnect.php","w");
fwrite($connectfile, "");
$dbh=mysql_connect ($serverurl, $nameofuser, $passofuser)
or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ($databasename);
[/code]

[Is there an 'OR' statement in PHP?]

yes OR exists in PHP

you can also use ||

[Search code redirect when nothing entered]

When you include a file, especially PHP files
you don't use the URLs

give a relative location
like
require_once "../includes/dbconnect.php";


reason for that is to keep people from stealing other people's scripts

[quote]1. My sql connections are correct, as they work [size=12pt]everywhere else.[/size][/quote]

by everywhere else do you mean another computer.
If you're trying to log into your MySQL server from somewhere else
you must make sure that that MySQL server allows that IP, or at least the range or domain.


If that's not the case double check your connection anyway, cuz it does say you're not issueing a password
