RE: [PHP] getting a number range from user input.. (weight)

[Murray @ PlanetThoughtful]

I don't understand why you have the 'Weight_kg = "6"' clause in your WHERE
statement?

Aren't you attempting to return one of the zone values depending on a value
that falls between range and weight_kg?

Let's say, for example, that the value you're searching for is .45. The
following statement would correctly return the record below:

SELECT * FROM rates_dhl WHERE .45 BETWEEN range AND Weight_KG

In your PHP code, you'd probably use a variable when building the SQL
statement.

Something like:



This is assuming range and Weight_KG are both decimals in your db, rather
than VARCHARS etc.

It may be that I've misunderstood what you're attempting to do.

Much warmth,

Murray

RE: [PHP] Reservation technique

[Roger Thomas]

Yes. I flipped thru the manpages and found:
expr BETWEEN min AND max
If expr is greater than or equal to min and expr is less than or equal to max, 
BETWEEN returns 1, otherwise it returns 0. This is equivalent to the expression (min 
<= expr AND expr <= max) if all the arguments are of the same type.

Thanks again.

Re: [PHP] getting a number range from user input.. (weight)

[Louie Miranda]

I have this on my db.

mysql> select * from rates_dhl where weight_kg = "6" between range and
Weight_KG;
++---+---+++++++++
| id | range | Weight_KG | Zone_A | Zone_B | Zone_C | Zone_D | Zone_E

| 18.48  | 21.32  | 23.63  |
++---+---+++++++++
1 row in set (0.00 sec)

When i did try the between, even when i try to change the weight_kg to
any number, it only display the first entry.

Put the weight ranges in a MySQL table and use the BETWEEN operator to
retrieve the appropriate weight.

Something like:

fromweight, toweight, value
0,0.5,9.45
0.501,1.0,10.71
1.001,1.5,11.97

Then, the following SQL statement will pull the appropriate value:

SELECT value FROM weights WHERE 1.3 BETWEEN fromweight AND toweight

RE: [PHP] Reservation technique

[Murray @ PlanetThoughtful]

> Great! Thanks Murray.

Hi Roger,

On second thoughts, perhaps the BETWEEN operator isn't what you're looking
for, since it will probably return false matches on bordering reservations.

In other words, someone attempting to make a reservation between 10am and
12pm might be told there's a conflicting reservation if there is already a
reservation for between, for example, 12pm and 2pm on the same day. The end
time of 12pm on the new reservation will return a match for the start time
of 12pm on the existing reservation using the BETWEEN operator.

As an alternative, you might try something like:

SELECT * FROM reservation_table WHERE (new_start_datetime >
reservation_start_datetime AND new_start_datetime <
reservation_end_datetime) OR (new_end_datetime > reservation_start_datetime
AND new_end_datetime < reservation_end_datetime)

This should exclude false matches on bordering reservations.

Much warmth,

Murray

[PHP] Reservation technique

[Roger Thomas]

I would like to do some sort of facilities reservation system. Suppose this is for 
booking , say, a meeting room.

Booking detail to be stored in db:
- name or id of person
- meeting room number
- date and time (when room will be used)
- number of hours to be allocated

Now say Peter booked room R1 for 20th Nov starting from 9am to 12pm.
Then Mary try to book the same room on the same date beginning 10am for 4 hours.

How will a PHP script perform such checking to prevent that sort of overlapping in 
reservation ? Or could it be that my database design is bad that's blocking ideas into 
my head ?

I need help.

Re: [PHP] getting a number range from user input.. (weight)

[Louie Miranda]

OK, here is what it should do.

I have a fixed range of weights from .5 to 20.0 Kg (kilogram) and for
each weight it has a succeeding value, i cannot jump or just round off
the numbers. So i need a range detector to do it.

Because for each of the item below:

> weight   value
> .59.45
> 1.0 10.71
> 1.5 11.97
> 2.0 13.23

I must get the exact value, so let say for example. I have 1.3 it
should fall under 1.5 the idea i had was to do this, so i can detect
where the number should fall..

range:
. => .5
1.001 => 1
1.501 => 2
2.001 => 2.5
2.501 => 3
3.001 => 3.5

and so on..

But i dont know how to do this on PHP

Hi Roger,

I think you need to check out the BETWEEN operator in MySQL (assuming you're
using MySQL? Look for the equivalent operator in whatever db platform you're
using, if otherwise). Essentially what you're looking to do is find out if
either the start time or the end time of the new booking falls BETWEEN the
start time or the end time of an existing booking. If either of them does,
it's safe to assume there's a booking conflict.

[PHP] getting a number range from user input.. (weight)

[Louie Miranda]

How can i match a range of numbers from a given input?
i tried round() but it rounds off the numbers to the next number, so
that will be wrong.

My example below show 4 examples of what my db tables looks like.

weight   value
.59.45
1.0 10.71
1.5 11.97
2.0 13.23

How can i get the range of:

.1 to fall under .5 and
1.3 to fall under 1.0 and
1.6 to fall under 2.0

and so on.. any ideas?

I'm a big PHP programmer, and would love to be able to test my scripts on my Axim.

RE: [PHP] getting a number range from user input.. (weight)

[Vail, Warren]

Not sure I completely understand what you are trying to do.  In your
problem, seems to me that both 1.3 and 1.6 would fall under 2.0 and neither
of them would fall under 1.0.  You must be using some logic that I am not
getting.  Can you be a little more specific?

Subject: [PHP] getting a number range from user input.. (weight)


How can i match a range of numbers from a given input?
i tried round() but it rounds off the numbers to the next number, so that
will be wrong.

My example below show 4 examples of what my db tables looks like.

weight   value
.59.45
1.0 10.71
1.5 11.97
2.0 13.23

How can i get the range of:

.1 to fall under .5 and
1.3 to fall under 1.0 and
1.6 to fall under 2.0

and so on.. any ideas?

[PHP] $_SERVER['HTTP_REFERER'] does not work

[Michelle Konzack]

Hello, 

I have a Host on DynDNS.org with the URL



In the Pages I like to check, whether the URL was called from
inside my Domain or not. For testing I have added 

echo $_SERVER['HTTP_REFERER'];

but it returns every time 

http://onlinestore.tamay-dogan.net/u/controller.php

which is the local Domain. In my 'apache' Include I have

  ( '/home/PUBLIC_HTTP/Configs/vh_/onlinestore.conf' )__
 /
| 
| ServerAdmin  [EMAIL PROTECTED]
| DocumentRoot /home/PUBLIC_HTTP/onlinestore/
| 
| ServerName   onlinestore.tamay-dogan.net
| ServerAlias  onlinestore.tamay-dogan.homelinux.net
...
 \__

But if I look in "Page Info" of Mozilla, it tells me the right Domain. 

Then I have the same problem with

echo $_SERVER['SERVER_NAME'];

which tell me every time the "ServerName" but not the public 
"ServerAlias".

WHY ?

Does anyone have an example, which I can put at the beginning
of my Web-Pages which allow or deny access to the HTML-Page ?

I need to protect my php-Scripts, because I have had already
a DoS by calling my php-scripts several tenthousandth times.

Usually you need to do this when the data is collected from a POST 
and/or you don't want the user to reload the page. The best solution 
(IMHO) is to use meta refresh.

[PHP] Session object destruction failed

[Pablo Gosse]

Hi folks.

Earlier today I received the following error when I tried to log out of
my CMS:

Session object destruction failed in [blah blah blah file info].

I googled this and took a look on bugs.php.net but couldn't find much
useful info.

Everything worked fine before, and has worked fine since, so I'm not
overly concerned.  I'd just like to know what caused it.

Any ideas?

Cheers and TIA,

Pablo

E_STRICT has a different purpose though.. it will report about
things that have been deprecated.

E_NOTICE is more like perls strict, which will complain that a
variable is being used that hasn't been initialized. But E_NOTICE
happens at runtime not at compile time.

[PHP] Getting all namespaces of a DOM document.

[David Schlotfeldt]

This should work perfectly. Thanks a lot!
David
---
Hello David,
I had the same problem some weeks before and solved it with the use of xpath 
(thus it isn't in the dom documentation of w3c but you'll find it under xpath 
recommendation):



	$xml = "http://anynamespace.tld/\";>nodeValue";
	
	$doc = new DOMDocument();
	$doc->loadXML($xml);
	
	$xpath = new DOMXPath($doc);
	$result = $xpath->query("//namespace::*");
	
	foreach($result as $node) {
		print $node->localName . " = " . $node->nodeValue . "\n";
	}
?> 


The xpath expression "//namespace::*" selects all nodes of the namespace axis, 
the namespaces. Maybe it is a bit heavy for bigger documents to traverse all 
nodes but it does its work...

If this is an acceptable solution to your problem, it would be nice if you 
could post our conversation on php.xml.dev news repository (news.php.net, but 
i think you'll know:). Thanks.

Furhter it would be nice if you would take just a minute to get to know my new 
project called eecoo - if you're interested in oop concepts of php5 and of 
course xml & co. you'll there be quite right!! You can find it under 
http://eecoo.dyndns.info/~brainbug/ (leave out ~brainbug to see the 
developement server, but currently under construction).

Thanks, and nice to meet you. hope i could help.

Vivian Steller,
Hi, I saw your documentation of PHP5's DOM at
http://www.eecoo.de/downloads/domdocumentation.txt and was wondering if
you could help me solve a issue. I have been using W3's website to
figure out everything I know about PHP's DOM since they follow it very
closesly. On a project I am working on I need a list of all the
namespaces in the dom document. I find that you can get the namespcace
uri if you have the prefix and the prefix if you have the namespace uri,
but i can not find out how to get a complete list. I do see the NameList
(DOMNodeList in PHP5) but I see no way of getting to it; or even if it
is implemented.
Anyways, my question is if your have learned of a way to get a complete
list of namespace uri's (or namespace prefixes) when using PHP5's DOM?
Thanks a lot for any help you can provide.

OK, I checked things out, and based on some private emails, and pointers, 
from Francisco M. Marzoa [EMAIL PROTECTED], I have now

replaced:
   readfile($name);
with:
while(!feof($fp)) {
$buf = fread($fp, 4096);
echo $buf;
$bytesSent+=strlen($buf);/* We know how many bytes were sent 
to the user */
}

I restarted apache (to free all the memory), and we will see how it goes 
overnight.

-Robin
BTW - output buffering is turned OFF. ob_get_level() returns 0, but both 
functions readfile and fpassthru seem to allocate memory (and never 
release) the size of the file.

Ok, so much for the theory. What about the output buffering? Have you 
checked if you have output buffering enabled? What das ob_get_level() 
return?

If it's activated but you can't find where it is activated then this may 
help to disable it in your script:

while (ob_get_level()) ob_end_flush();

I'm still a bit fuzzy on how to write it out.

So if field is labelled f5
Then I'm doing a $_SESSION['f5'] = $_POST['MyText'];
then I think it would be 
$f5 = htmlentities($f5, ENT_QUOTES);

insert $f5 into database ?

The only difference between readfile() and fpassthru() is what parameters 
you pass it.

Something else is the problem, what version of php are you running?
I am using php 4.2.2
OK - I lied.
The same problem exists with fpassthru (now that I have let it run a little 
longer) I now have 5 sleeping httpd processes on my system that are

No Mysql won't do it.  PHP validation would have to be

RE: [PHP] Question: Validation on a text field

[Vail, Warren]

Assuming that the pasting is done into a  on an html
form, I believe the Textarea will limit the past to just "text" characters.


I suppose this could be dependent on the browser.  

I don't know of any html input control that would allow "blob" (binary)
values.

I also don't know if MySQL will police things input to a text column to make
sure they are valid ascii text characters.

RE: [PHP] Strange query

The second limit parameter is the actual number of rows to limit to, and in
most situations this is usually the same number (i.e. 0,15; 15,15; 30,15;
etc).  It is too bad this clause is not supported by some of the other
databases I have had to use, it makes a convenient way of paging where the
second paging parameter specifies the page size in terms of rows to retrieve
(first parameter is the starting row number starting with zero).

On a number of sites a message and/or graphic is displayed asking you to
wait or be patient whilst some processing is being performed to compose the
next page.

How are these done within PHP scripts?
Could output buffering be used for this purpose?
For example is it possible to do something like:

The only difference between readfile() and fpassthru() is what

Which may get you close but either way would probably be more indicative
of the service providers location then the actual user and even
narrowing it down to a single city does not mean you have only a single

I find it hard to believe that your choice of browser affects the

Where is this report?
I may have been mistaken about the "report":  "Windows versions of PHP 
prior to PHP 4.3.0 do not support accessing remote files via this 
function, even if allow_url_fopen is enabled."  (Found at 
http://us2.php.net/manual/en/function.imagecreatefromjpeg.php)  The 
server is running Linux, so it's not Windows PHP, it's the client (IE).

I find it hard to believe, too.  The error is (as I recall) "call to

Yes, I understand, but not to know even if you are in the right order of 
magnitude, is kind of scary isn't it?

For example on my system, I have 1 Gig of physical memory, and 3Gig of 
swap. If I end up with only 512k free - something is very wrong, and I 
should disallow functions I know that eat up memory. There is a low 
probability that multiple connections will pass the test, and then consume 
the memory, so yes this is not 100% coverage.

Maybe what I am seeing is actually a bug in the way that readfile() handles 
low memory situations. If there is not enough memory for internal functions 
to run, they should error, not crash your system.

I assume that the way the converstation is moved is that there is not a way 
to see what free system memory is, without calling a command line function 
(free or mem).

A second problem, and why I want to create some PHP to mimic crypt()

A side note; I am amazed that no one else on this list can or is jumping 
into this discussion about using PHP to mimic PHP's crypt() function in 
order to create "unix style" MD5 passwords.  I know it has been done 
before, and can be done probably many different ways.  The idea of using 
system() or exec() to call MD5 is an option I will be looking into, 
however, I know there must be another option.  I have considered 
rewriting my own version of crypt() to not use libmcrypt but the 
information on the C-like Zend language used to write your own embedded 
PHP functions is a bit vague in regards to me "getting over the learning

my existing crypt() based code will resume functioning as expected.

Where is your PHP package coming from? If you've already been using 
the http://entropy.ch binary, maybe you should try compiling your own. 
Or get (and either compile yourself or just install binaries) it via 
fink (http://fink.sf.net/) which often gives you different options for 
libraries to use and such during install. Or any number of other 
options. I wonder if there is some build option or something setup in 
the configuration process that affects this. I seriously wonder how 
libmcrypt could have this sort of limitation under OS X, but I am not 
that type of programmer.

I would encourage you to play with this and post your results to the

Galen,
Thank you for the response.  I understand where you are coming from; 
your use of MD5 hash.  In short, my goal is to recreate crypt()'s 
method of creating "unix style" passwords without using PHP's 
built-in crypt() function... (as seen in /etc/shadow on a *nix 
server, ie. $1$sed$blaaah instead of standard MD5 hash which 
does not use $1$$ to store a "seed".)

Ultimately, my problem exists related to the server I am using, where 
the server's PHP crypt (using libmcrypt) returns with the fact that
CRYPT_MD5 = 0 .

In researching, I have been told that this is a limitation of Mac OS 
X, that "there is no way to have libmcrypt support both DES and MD5" 
on this OS.. but I know there must be a way because it is easy to 
have a FreeBSD server use both DES and MD5.

I had an old BSD box online for years.. where old account passwords 
in /etc/shadow were encrypted via two character salt DES.  One day, I 
made a simple change to the box's config and then any new accounts 
created would use MD5.  The "coolest" part is that any old passwords 
in DES could remain DES, and BSD's libmcrypt could determine if a 
passwd in /etc/shadow was DES or MD5 and handle accordingly.  
Obviously, this kept me from having to call clients and change their 
password so as to re-encrypt their respective /etc/shadow entry into 
MD5.

I hope this email better explains my situation.   I'll check out man 
md5 on the Mac box and see what I can figure out.  In the meantime, 
if this email helps to generate any ideas which may be helpful in my 
current quest, your input would be most appreciated.

Thanks again,
Kris

On any system, the md5 binary, md5 php function, and MySQL md5 (in 
most cases - though in certain situations you could have problems if 
you have a field of the wrong type or length) all work exactly alike.

This is how I have always thought of md5 and considered it to be

There have never been seeds or anything else involved in my

Well, you *could* have a form that displays asking for their zip code;
on submission, it sets a cookie with their zip code, and this allows
them to see their personalized movie times on subsequent visits. (You
could even hide the zipcode form if the cookie is set)

$free = shell_exec('free -b'); $i=0; while ( $i != strlen($free) ) {
i = strlen($free);
free = str_replace('  ',' ',$free);

$free = str_replace("\n",'',$free);
$freeArray = explode(' ',$free);
$total_free = $freeArray[9] + $freeArray[18];

Does anyone have any ideas that could be used on all OSes? i.e. 
Without shell_exec()?

Thanks in advance.

Something like this should work:

You would have to determine their IP, which, some being dynamically
assigned at log on, would not necessarily indicate the users location.
Then you would have to be able to map the IP to a zip code. The short
answer is no.

well ofcourse it "keeps the get variables" as you put it. PHP_SELF is 
the path and arguments that php was called with. use phpinfo(); to find 
out which variables hold the real path, make sure to add some random 
"get variables" when calling that script so you see the difference

No. I must admit, It don't understand it. Let me try: You have a script

b.php outputs the static content "
This can't work. You browser tries to download an image with the name

did not understand you problem. If you use a PHP script inside an img 
src attribute then this PHP-Script must output an image. Complete with 
content-type header and the image as binary data in the body.

Or another solution for a.php:

 
  
 

but I don't see the sense here. You can just do all this in one script:

  $img = 'a.jpg';
}
else {
  $img = 'b.jpg';
}

It's not clear what your PRINT macros are doing. Maybe you forgot to

[PHP] Very wierd issue with pdf's and rotating images

[Brent Clements]

I have tried this with pretty much every pdf library available to use with PHP and all 
have the same results.

1. I create a new pdf.
2. I rotate a jpeg using gd's imagerotate 
3. I output the jpeg to a new pdf page
4. I then output the pdf to the browser and/or to a file.

When I view the pdf, the image that was embedded in the pdf page has a large black 
rectangular area taking up the first 1/4 of the image.

If I do not rotate the image, there is no large black rectangular area.

Anybody has an idea what's going on?

Thanks,
Brent

I'd read the (free) online docs first:

It's a CMS system, it can't be _that_ difficult to learn to run. 
Since it's a 'system' you probably don't have to know much about PHP

Not unless the docs were insufficient.

Why not download it, install it and find out all these answers for

Very true. In Java (with Tomcat for example) you have a real session 
scope and application scope where you can put objects and directly 
access them. These objects are hold in memory and they are REAL objects 
between the requests. In PHP it's different. If a HTTP request is 
finished then the session (with all data including objects) is 
serialized and stored on the harddisk (or database or whatever the 
session backend is). On the next HTTP request the session is loaded from 
harddisk and unserialized. So new objects are created and filled with 
data from the harddisk at every request.

It would be REALLY REALLY cool to have an application-server-like thingy 
in PHP. But as far as I know there is none. Correct me if I'm wrong.


The other issue is running a thread that enable in some time interval to 
write snapshots from the log files that are being generated. Is it 
possible to have part of the script alive in some sort of a thread even 
after the script is dead. For example with the use of the sesssion 
variable.
You can write a command line PHP script and run it as a separate daemon 
or call it from the crontab.

If you store huge variable names then it will be slower than if you
store small ones.  Same with the session variable values.

PHP sessions variables are stored as a semi-colon delimited string of
text, with other appropriate seperation characters and descriptions of
the variables included.  I minimize my session variable names to a
single character and document them somewhere for future reference.  I
make sure and store minimum values for each variable, for example the
integer 1 instead of the string 'true' or 'yes', things like that add
up.  Sessions are as efficient as you make them.

Also, PHP doesn't have threads.  You can use some of the execution
functions to simulate them to some extent however:

[PHP] Sessions and threading

[Devraj Mukherjee]

Hi everyone,
I am attempting to write an implementation of Prevayler 
(http://sourceforge,net/projects/prevayler), which has originally been 
written for Java and provides a prevalance layer for storing objects 
using incremental log files and taking snapshots of in fixed time intervals.

It seems the Java guys are widely using the implementation even for web 
applications. There are many advantages to using the system, backups and 
restores are very easy and reliable and it is very efficient for small 
sized projects, as the Prevayler guys claim about 9000 times faster than 
Oracle ;-)

I have near worked out everything that has to be done, I think I am 
going to try and write it as a PEAR module for it to be available to 
everyone. I am stuck with a few concepts and I thought I might float the 
ideas here to get some feedback before I start scripting.

The first part of the problem is that I need to be able to at all times 
maintain a readable set of objects in memory, I am planning to achieve 
that using session variables, but I hear that session variables can 
become very inefficient, how true is that?

The other issue is running a thread that enable in some time interval to 
write snapshots from the log files that are being generated. Is it 
possible to have part of the script alive in some sort of a thread even 
after the script is dead. For example with the use of the sesssion variable.

Any feedback is very welcome.
Kind regards,
Devraj

[PHP] Shorthand functions (was: Code Snippets' you couldn't live without)

[Klaus Reimer]

Murray @ PlanetThoughtful wrote:
with exploring include files to find out what a function does or how a class
operates. I doubt half-a-dozen shorthand functions in that include file
would place a measurable strain on the readability or maintainability of a
project. 
I disagree on that. The problem here is not that the functions are 
short. The problem is, that their names gives absolutely no clue about 
what they are doing. mfr() can be mysql_free_result() but it also can be 
mysql_fetch_row(). So it's not only unreadable, it's also error-prone. 
Sure, it's possible to look up what this function is doing. But is it 
necessary? Everybody (even coders not knowing the mysql functions) can 
understand what "mysql_free_result()" is doing, without decyphering it 
first.

But I agree that many PHP functions are named too long. But this is 
because they are non-OO functions living without namespaces. So if you 
don't use OO (where you may write something short like $res->free()" you 
have to live with that, I fear. Or write shorthand functions, nobody can 
keep you from doing so. I just said, that it is problematic for more 
professional projects where new programmers may begin to work on at any 
time).

And I agree that there are even some very short function names in PHP 
like nl2br(). This looks like a bad naming, but it is not really. "nl" 
is a well known shorthand for newline. "2" makes clear that it converts 
something. And "br" is named after the HTML-Tag. So this function name 
GIVES some clues about what it is doing. But for newcomers it may not be 
clear at the beginning what this function is doing. But after a quick 
lookup the newcomer can remember the meaning very well. And I think this 
is different with functions like mfr() and asl() which gives no clue 
about their meaning.


when first viewed by someone new to PHP. Also witness the deprecation of
variables such as $HTTP_GET_VARS in favour of $_GET etc. 
$_GET and $_POST are well named. It's clear what they are doing. Thank 
god their were not named $_HGV and $_HPV.


Or the .=
concatenation assignment operator as a shorthand to $var = $var . ' added
string.' 
"$a .= $b" is not a shorthand of "$a = $a . $b". The result is the same 
but the internal processing is totally different. "$a .= $b" is a lot 
faster then "$a = $a . $b" because $b is directly appended to $a. The 
second form constructs a completely new string and overwrites the old 
value of $a. At least this is the case if no optimizer is used. Maybe 
optimizeres are transforming the second form into the first form, don't 
know.

So you can't compare this to a shorthand function. It was not introduced 
because coders are to lazy to write the long form. It was introduced 
because it is absolutely intuitive to do so if the language already has 
something like "+=". But I can't tell if these operators were introduced 
into the C programming language (or wherever it appeared first) because 
lazy coders. ;-)


Back to the intent rather than the form of my original question: what are
the code snippets you can't live without?
I already posted some. But this thread is interesting, too. So I changed 
the subject ;-)

Re: [PHP] what am i doing wrong..??

[bbonkosk]

Echo out your queries!
$query = "insert into joke values('',".$_POST['joke_text'].",'date')";
---> echo $query;
$result= mysql_query($query);

This will tell you what is going on, perhaps some of the information is not set?  You 
can even copy and paste the output to run against your mysql backend on the command 
line to see if additional information/errors are present.

[PHP] what am i doing wrong..??

[Aalee]

Hi there please have a look the code below...I dont know wht am doing wrong
here...
This code is suppose to show the number of jokes in a mysql database and
allows user to add a joke when the user clicks addjoke link. And when the
joke is added, it suppose to say that "Joke inserted, Thank you" and list
all the jokes below this line. So far am able to view all the jokes and take
the user to add joke page. But the problem is when the user clicks insert
joke button, it does not display the message "Joke inserted, Thank you" and
the jokes are not listed. Infact it does not give any error aswell, it just
stays on the add joke form page. I checked the database and no joke is
added. Working on PHP ver 4.3.8 with register_globals turned OFF and Apache
1.3.31. MySQL ver 4.0.20a on winXP pro SP1.
Recently i started using registre_globals OFF and all these probs strted
coming up. This code was working fine with globals ON. But my hosting has it
off. So need to do so. I was able to fix all the other issues came coz of
this global thing in this code. But stuck on the issue i just mentioned. Any
help would be GREATLY appreciated.



  Type your joke :
  
   
  



";
 echo mysql_error();
}
$color1 = "#66CCFF";
$color2 = "#66CC99";
$row_count = 1;

// -- Following lines list the jokes in the
database 
echo " These are the jokes we have got so far";
$db = mysql_connect("localhost","homesite","test")  or die(mysql_error());
mysql_select_db("jokes",$db);
$sql = "SELECT id, JokeText, JokeDate from jokes";
$query = mysql_query($sql);
echo "
   
ID
  Joke Text
  Joke Date";
while ($myrow = mysql_fetch_array($query))
 {
 $row_color = ($row_count % 2) ? $color1 : $color2;
  echo"".
  "". $myrow["id"]."".
  "". $myrow["JokeText"]. "".
  "". $myrow["JokeDate"]."";
  $row_count++;
 }
echo "";

$current_url = $_SERVER['PHP_SELF'];
echo("" ."Add a Joke!");


} // end main else statement
?>
