I believe it should be:
<?
if($NextCourse == 1){ do something; }
elseif(!$NextCourse){ do something other; }
<?
By the way you have your statement, I think you are only looking for the
"1". You might try the following instead.
<?
if($NextCourse == 1){
do something;
}else{
do something else;
}
?>

ok. the key problem is when I click the button to submit.
the value of $NextCourse is not the value of value
of document.form1.NextCourse.value.
just is the pre page's $NextCourse,that's say "null";
how can i get document.form1.NextCourse.value?

How are you passing the variable $NextCourse to this script?

I used to encounter the same problems with reporting in our business
software. You can generate reports and spit out HTML in a new window
and have the user print the report from the browser, but that has many
drawbacks. It only works with simple data sets, its difficult (or
impossible) to control page breaks, lack of precision placing, etc.
Now I use FPDF to generate PDF reports (http://www.fpdf.org/). Its
free, easy to use, and pretty flexible. It allows you to do precision
placement on a page, add headers, footers, etc, etc, etc. Be sure to
check out the "Scripts" section, its got a bunch of useful tips for
expanding functionality of the classes. There is another commerical
product out there (can't thin of the name right now) that is supposed
to be faster, but FPDF is pretty fast in our applications.
I find doing it this way a total pain in the ass, I have in the past
used htmldoc , to generate html to pdf , it has special tags to do
certain things in the pdf's. Seriously drawing it like this is time
consuming. I would suggest report designers like report manager and
jasper reports. Currently for Excel I have built a subclass to the PEAr
structures datagrid which uses the excel spreadsheet renderer, and i
give it a database resultset, currently the dataobject, and then it
will generate the columns dynamically from the query. I have given it
extra methods to display extra stuff in the header and footer ie for
formulas , and special formatting on the cells. But pdf's are nice if
the user doesnt need to collate the data just print it.
The funky thing with Jasper reports is, you can maniuplate the xml
based files, say build a web frontend to build a report builder, so the
user doesnt need to use gui tools like iReport to create report
templates. So you let them select the fields you want, and u do the sql
and xml generating in the backend. To do it currently, the fields have
to be statically setup , it also however requires a Jsp to run a
servlet to compile the reports. Reportman however runs a cgi report
server, but cant do excel on unix.
I also use the JPGraph package for generating graphs
(http://www.aditus.nu/jpgraph/). This is *really* slick. Its free
for personal use, about $125 for commercial use. You need to install
some additional PHP libraries (JPEG, PNG, GD at least), but its fast
and easy. I love playing around with this product because the
possibilities for what you can do are almost endless.
This is really sweet however it doesnt have PHP5 support ?

Hello,
I have a system that uses certain id info. This info is stored in a session
cookie in MD5 format. At certain parts of the code I need to update or
insert to MySQL DB with that id info value in cleartext. Is this possible?
If so, how to put this to a sql query?
$sqlquery = "insert into x_table (team_id,number,) values
('$team_id','$number')
$team_id is the MD5 formatted cookie value and I need to put it to the
x_table column team_id in cleartext.
Thanks a lot

MD5 values are hashes, not encryptions. There's nothing to "decrypt".
It's good for storing the results of some value and than when the person
sends the MD5 back at a later point you can make sure it still matches
the desired value by re-hashing the original value again.

sp_help @objname='{tablename}'
This will actually return several recordsets which are probably
available individually in the other responses I've seen to this
message. I just wanted to make the list of options more complete.

Did you check GIMP? It has an option to make HTML image maps.

Hi!
I need to create an image map on a country map, where people
can click on any state and get some info related to it.. In
such case the regular polygon/circle/rectengle image map wont
do bcoz of shapes of state..
I guess this must be possible someway in PHP.. please tell me
if you have any idea how to go abt this..
Is the problem you're experiencing that the image map isn't being
built properly or are you passing information to it that does not
appear to be consistant.
If it's the former, then PHP has nothing to do with that. I'm sure
you can find some tools to generate image maps for you. There have
always been free ones with a minimum of effort.
If you're having problem with PHP in the mix, can you describe the PHP
problem, provide some code, some sample output, etc.?
I've used image maps in the past (though I try to stay away from
them) and you can create a link with virtually any polygon if you
have the patience to may out the plot points. You could easily create
a star with many, many points and have it be clickable - which would
indicate that most states would be a piece of cake.

Thanks John,
I never knew about any such thing in Gimp :)

Noong 06:24 AM 4/23/2005, Ang sabi ni Richard Lynch...
Is an undefined function one of the examples? If not, try one of those.
I use the examples given in the example and it works but I'm not after
errors inside a function. I'm trying to see, what if I forgot to create a
function or what if I mistyped a function, then it should trigger a fatal
error using the custom error handler.
Also, did you remember to call http://php.net/set_error_handler as well as
to define the function?
As I've said, I copied the sample given from the manual so here it is:
$old_error_handler = set_error_handler("userErrorHandler");
No, I did not define the function because like I said, that's what I'm
after. What if I mistyped a function or forgot to define a function or the
file containing the function goes missing, etc.

Hello,
I writing a script that allows user to update a soccer league table with web
form. I made a script that prints the old values to text fields in the form.
It's done with a loop so that each text field name is numbered +1 higher
than previous.
My problem is how to put the changed data back to the DB with a different
loop since the variable names chance for every team.
Here's the a sample of the update part( only one column to update). This
script gets 14 game and team values from form
like this; $new_games1,$new_games2,$new_games3,$new_games4 etc (and same for
the $team).
$sql="SELECT name FROM x_series WHERE team_type = 'series'";
$result=mysql_query($sql);
$rounds = mysql_num_rows($result);
$count = 1;
while ($rounds >= $count) {
$sql = "UPDATE x_series SET games = '$new_games1' WHERE name = '$team1'";
mysql_query($sql);
$count++;
}
So how can get the game and team variables to change (+1) each time the sql
query is fired? Or can I? Is the alternative to write 14 different sql
queries? Sounds stupid.
Hope someone gets my idea and can help. I've been banging my head against
the wall with this and I'm running out of fresh ideas. I really wouldn't
want to write those separate sql queries for each update if its possible to
avoid that. Thanks a lot.
-William
