Hi there, I have a db with only one table in it called "CONSULTANT". I'm
using sqlServer and would like to do record paging, say 5 at a time. I'm
aware that sqlServer doesn't support the LIMIT statement so I've decided to
do it using arrays.
So I've written the appropriate query statement, managed to grab details for
each consultant and dump that array into a new array called
$consultantarray.
Now, what I'd like to be able to do is this...return 5 records at a time.
Have 2 links called "next" and "previous" that when clicked adjusts the
$consultantarray accordingly.
Can someone take a look at my code below and tell me where I have to go from
here. So far the arrays are fine (meaning they are holding the appropriate
values), just the display of the appropriate records from the array is my
big problemo. :) I currently have a foreach loop being used, but am unsure
if this is the correct route to take, in fact, I know this isn't right
because it's displaying the records oddly.
Thx for your help, Joe :)
<?php
#connect to db
$connectionToDB = odbc_connect("cdxcet", "joecqon", "joecoqdsn");
#create query statement
$sqls = "SELECT consultantid, firstname, lastname, city, stateprovince,
country, category, yearsexp FROM CONSULTANT WHERE category ='$category'
ORDER BY yearsexp DESC" ;
#execute the sql statement (query) on the connection made
$resultset = odbc_do($connectionToDB, $sqls);
print "<h4 align='left'><font color='#663399' face='verdana'>Consultant

Why not just add a simple check inside that while loop?
if($temprow['div_id'] != $home_div_id)
echo "<option value=\"" . $temprow['div_id']
. "\">" . $temprow['div_name'] . "</option>\n";
Seems more logical to me than to mess with the array itself.

I would do it another way.
say you have all the possible choices in an array that come out of a
database, and ypou want, if the user already selected one, this one to
be selected, right?
Then i would set the selected atribute only if the value out of the
database is the same as the one submitted by the form:
like this (omitting the surrounding html):
$query= "select distinct * from sometable";
$result=mysql_query($query);
// the select field is named selectfield,
echo "<form name=\"myform\" action=\"$PHP_SELF\" Method=\"post\">";
echo "<select name=\"selectfield\">";
// the variable $selectfield is, if set the value submitted by the form
$selectfield = $_POST["selectfield"];
while ($row=mysql_fetch_array($result)){
echo "<option";
// assuming the second element of this array holds your
// choices then
if($selectfield == $row[1]){
echo " selected";
}
echo ">" . $row[1] . "</option>\n";
}
echo "</select>"
echo "<input type=\"submit\">\n";
echo "</form>";
i think this is a more straightforward solution for your problem...

Because, as a dope, I forget that you can invert IF statements like
that -- you're right, I'd rather do that than mess with the array.
Although the feedback on unset($arrayname['index']) was extremely useful
knowledge! Thank you everyone.

It happens a lot here that people ask questions that could easily be found
by browsing the manual or searching the PHP FAQ and website.
Some people really should read the FAQ and manual (php.net) when they have a
question and preferrably search an archive of this list (deja.com).
It really won't hurt to at least check those first chapters of the manual, so
you know what answers you can find there.
Also, a searchengine (google.com) can answer almost any programming question.
This would save the people on this list much time reading messages,
answering (or referring to the FAQ, manual or previous posts) and will
ultimately save yourself some time waiting for replies.

May I add that using an appropriate and descriptive subject text would
increase the chances of questions being read and answered. It also helps
others who may be having similar problems to easily determine which posts
they should be reading.
Subjects like:
"Quick question"
"Please help!!!"
etc usually find their way into my trashcan without being read :)

one of my biggest problems, which happens here a lot, is that some people
will ask a completely different question (with a different topic header)
under an existing thread rather than starting a new thread. all it takes is
a few minutes to familiarize oneself with the newsreader, but apparently a
few minutes is too much..

Many people use mail clients that don't do any sort of threading to follow
what's going on on this list; I use Eudora, personally, when in Windows,
and the Mozilla mail client when I'm in Linux. It was, quite literally,
years before someone finally pointed out to me that in a mail reader or a
news reader that supports threading, if I start a new thread I shouldn't
reply to an old thread with a new subject line. I'm now very careful to
follow that procedure. In my mail client, it makes no difference, but I
know it affects other readers.
That's just why it happens; because not everyone uses a newsreader to read
this newsgroup, so many people don't even realize what's happening.

On a related note, outside of strings one should always surround keys with
quotes, so:
$arr = array('a' => 'apple', 'b' => 'banana');
print $arr['a']; // apple
print $arr[a]; // apple BUT this is bad
Without the quotes is bad because PHP first:
a) looks for the constant named 'a'
b) if constant 'a' is not found, an error of type
E_NOTICE is thrown.
So, let's do this:
define('a','b');
print $arr['a']; // apple
print $arr[a]; // banana (no error)
Because constants are not looked for within strings, the following is
appropriate:
print "an $arr[a]"; // an apple
As are:
print "an {$arr['a']}"; // an apple
print "an ". $arr['a']; // an apple
Anyway, maybe that helps explain a few things :)

It seems that you are saying that not using quotes is bad (first), but
then later you show that omitting the quotes does not result in an error.
Or are you saying that the quotes can be omitted if the array element is
being used in a string (between quotes), but generally the quotes around
the constant are needed to perform non-string operations?
Thank you,
Erik

Hi again Michael:
Digging documentation I found out that this behaviour (string and int keys)
is native for mysql_fetch_arrow() (found into the help: 'In addition to
storing the data in the numeric indices of the result array, it also stores
the data in associative indices, using the field names as keys. ')
So the question is answered. Thank you for your help.

Hi again Michael:
Digging documentation I found out that this behaviour (string and int keys)
is native for mysql_fetch_arrow() (found into the help: 'In addition to
storing the data in the numeric indices of the result array, it also stores
the data in associative indices, using the field names as keys. ')
So the question is answered. Thank you for your help.
Best regards

You need to install MsSQL support for PHP, by getting the right PHP module
and adding it in your 'php.ini' file .... see this file for the exact syntax.

this question is too general - you should describe your idea of what you
want to do and where your problem is a bit more.
In general is is you who would be responsible to write the code that
checks if a user is authenticated and should have access to something,
and you have to include that piece of code at the beginning of each page
you want to limit access for.

this either a mysql related question - as mysql deals with the problem
that a user has to be authenticated within mysql_connect or
mysql_pconnect to access some information - or it is a matter of your
application design - if you want only special users to do something or
to get some views of the data you queried from mysql you can go and
create a user table with users and poasswords, and a permission table
where users are designated to specific tasks, then, before you show some
data in your script, you ask the user for a password, look him up in
your users table, and only let him view the things he is allowed to.
but, again, this is a very general answer on a general question, which
might be the reason why nobody answered until now, to get some real
useful answers or solutions to your problem you have to be more specific.
maybe you want to go through some basic tutorials first before doing
such comlicated things and learn the basics of php and mysql before
playing around with big applications, permissions for users, etc...
(sorry, got no URL for something lkike this at hand now, use google)
hope this still helps

You mentioned that {$num_recs} and ${num_recs} both work -- I'm familiar
with the second form from bash shell scripting, but not the first. Do
they both work in all instances, or is one "preferred" over the other?
Thanks Mike

Hi
I built PHP on an ALPHA running OSF V5.1
I did the install after the make just like i did in the past.
This time, however, when i do:
apachectl start
i get this:
/usr/local/apache/bin/apachectl: 323331 Memory fault
/usr/local/apache/bin/apachectl start: httpd could not be started
There are no error messages being print to any apache logs.
Now, I had apache running previously with PHP. I realized that imap had
not been properly installed into my PHP so i went back and rebuilt PHP.
Now I get this problem.
This is my configuration:
./configure --with-apxs=/usr/local/apache/bin/apxs
--with-mysql=/usr/local/mysql --with-gd=/usr/local/src/gd-1.8.4
--with-png-dir=/usr/local/src/libpng-1.2.0
--with-zlib-dir=/usr/local/src/zlib --with-curl=/usr/local/lib
--with-calendar --with-jpeg-dir=/usr/local/src/jpeg-6b/ --with-imap
(imap was installed by putting c-client.a in /usr/lib and the appropriate
header files in /usr/include)
This time around I had to edit a php source file:
in ext/standard/scanf.c
and make the function scan_set_error_return to NOT be an inline function.
Has any had this problem before?
thanks!

Quick tip -- locate and whereis are your friends in the shell. They make
finding executables like php are a snap.
As for emailing from php/cron, it depends on how your system is set up.
Many email servers bounce any emails they receive from IPs that they can't
reverse map or otherwise identify. If your machine is on a LAN for
instance, the emails will probably get bounced.
Another thing to check is that your user account can actually use your
system's SMTP service. Email sent with php's mail() function are usually
sent by the owner of the script (or the web server's user).

Hi Everybody,
Has anyone doing it sucefuly? I can compile it. The phpinfo(); call
returns ok! (UCD-Snmp enable) but when I call the snmp functions I got a
SegFault (on PHP-CGI). I already tried with an without
--enable-ucd-snmp-hack, and recompiling the UCD-Snmp packages as told on
the PHP manual pages (http://www.php.net/snmp).
Any tips on this?
Thanks in advance,
Antonio.

Hi,
I am currently developing a site which makes use of SSL and sessions.
However, sometimes when I submit
form data (from an SSL page to another SSL page on the same server), I get
an error saying "This page
contains both secure and unsecure items. Do you want to display the
nonsecure items" (I have had these
results in IE5.5 and IE6, possibly IE5 too). If I press yes, a DNS error
page appears. If i press no,
a page saying simply "NavigationCancelled" (without any spaces) appears.
This error seems to happen
randomly, and only when form data is being sent with POST (I haven't tried
it with GET or anything else
as it may be a security risk to have the form contents displayed in the
query string).
I have found a way to fix this, however, it had some undesirable affects
with pages being cashed (and
therefore not being displayed with any changed session variables). This
"fix" was done using session_cache_limiter('private'),
but I don't want to use this due to these caching effects.
Does anyone have any suggestions that could fix this problem? I would be
very grateful.

Well, I did not configure it any particular way.
I just tried to build the mod_php4 port on FreeBSD. I assumed it would
work. Why would the FreeBSD port developers commit something to the stable
release that doesn't work?
Thanks,

I think FreeBSD uses rc.conf - check the shlib_dirs variable, IIRC.
And a note about your earlier reply in this thread: I'm only guessing
this will fix the problem. That's been the fix when I've seen error
messages like that in the past when trying to load mod_php.

Hi,
I am rather new to PHP so I hope somebody can help me.
I have a normal button (HTML code). Then I have made a function
function multiply($X)
{
return 2*$X;
}
The button has an OnClick, which calls my function.
<INPUT TYPE="BUTTON" name="HH" value="Mul" onClick="<? $XX=multiply(5);?>" >
I then writes $X to the screen.
<?php echo $X ?>
The problem is I dont even have to press the button. When the page loads it
already has calculated 2*$X. Why is that. I would like to only call my
function when I press my button.
Please help

PHP is a server-side language (i.e. Perl when used with mod_perl), not a
client-side language (i.e. JavaScript). All of the processing is done on
the server BEFORE it is sent to the user. Therefore, you can't call a PHP
function directly from a web page after the user has received it, since all
of the processing has already been done.

What value is it returning 5, or 10?

Of course, I think in my case the expresion is 'barking up the wrong

PHP is entirely server-based. So when you load this page into your
browser, all of the PHP is being parsed BEFORE it ever loads into the
browser. So the function will be executed even before the page loads.
Do it in JavaScript if you want it to be done in the browser. What you
have written down will show up in the source code of your browser as:
<INPUT TYPE="BUTTON" NAME="HH" value="Mul" onClick="1">
(or something like that).
PHP runs entirely on the
server. Server! Server! Server! Server! Honest, I promise that it
doesn't get interpreted by the browser. If you have any doubts, try
writing a PHP script, reading it in your browser, and then viewing the
source code to see what gets rendered.
For browser-side scripting, I suggest you pick up a book on JavaScript
programming. Nothing you do in PHP will ever be interpreted by a browser.

I am curious if using the same mysql_query() function twice causes some
kind of problem.
It seems that if I use
$result = mysql_query($sql, $db);
if (mysql_fetch_array($result)) {
while ($row = mysql_fetch_array($result) or die("You lose. No data
fetched.")) {
// print some data
// print a simple sentence to see if the WHILE statement even
executes
}
} else {
// print "No results match your criteria"
}
In this, I have used the $result variable twice. $result is essentially
nothing more than a mysql_query() function. If I do the above, then the
IF statement is true but the WHILE statement doesn't seem to produce its
intended effect. In other words, I get the die() message "You lose. No
data fetched."
This leads me to believe that I can't run two instances of mysql_query()
or perhaps mysql_fetch_array().
Does anyone know for sure if this is the case?

I'll most likely be corrected (I just joined the list to brush up on my
php) but I think that if you change this
> while ($row = mysql_fetch_array($result) or die("You lose. No data

You'll be on the right track.

No, of course you can.

EXCELLENT!
It worked perfect.
So $result can't be used twice -- I wonder if it somehow is altered by
the mysql_fetch_array() that is performed upon it.
Thanks Nick.

That's not it. Your first $result is a resource indicator (container for
results) so if you re-assign it (put another value into it) it becomes
useless as your while statement depends on it.
Happy to help :)

(This may be redundant, but I'm hoping that someday someone will find
this info in the archives as helpful:)
<INSIGHT!>
Now I understand. I was mistaken in the way that I first conceptualized
the following:
$sql = "some SQL code";
$result = mysql_query($sql, $db);
Originally, I thought that $result was just a variable that represented
the function "mysql_query($sql, $db)". And when $result is called by,
for instance, mysql_fetch_array(), in the form
"mysql_fetch_array($result)", all I was really doing was making a more
organized form of this:
mysql_fetch_array((mysql_query($sql, $db)))
But no! It appears that defining the variable $result like so:
$result = mysql_query($sql, $db);
Is actually performing an operation! The mysql_query() function happens
at this time! Not during the mysql_fetch_array() as I previously
thought.
If what I have written above here is correct (and I hope it is) then you
have helped me learn a fundamental element of the way PHP works, at
least with this command. I had not been thinking of $result as a
"container for results" before, rather as a "container for another
function for later use".
Awesome.

After lots of trial and error I traced the problem back to a missing
browscap.ini, I commented out that line in php.ini and it worked
fine. I guess it was causing php to think the it wasn't dealing with
a browser so it sent the headers differently (or something)
thanks to everyone.

Hi,
I am currently developing a site which makes use of SSL and sessions.
However, sometimes when I submit
form data (from an SSL page to another SSL page on the same server), I get
an error saying "This page
contains both secure and unsecure items. Do you want to display the
nonsecure items" (I have had these
results in IE5.5 and IE6, possibly IE5 too). If I press yes, a DNS error
page appears. If i press no,
a page saying simply "NavigationCancelled" (without any spaces) appears.
This error seems to happen
randomly, and only when form data is being sent with POST (I haven't tried
it with GET or anything else
as it may be a security risk to have the form contents displayed in the
query string).
I have found a way to fix this, however, it had some undesirable affects
with pages being cashed (and
therefore not being displayed with any changed session variables). This
"fix" was done using session_cache_limiter('private'),
but I don't want to use this due to these caching effects.
Does anyone have any suggestions that could fix this problem? I would be
very grateful.
Richard Hilton.

This is probably more of an HTML question, but...
I would like to have the ability to upload files onto a site, however using
the normal HTML <input type=file...> results in a somewhat disgusting
looking control which I cannot seem to get to fit into my site's theme.
Is there a better way - remembering of course that I still need the facility
to browse the local system for a file
Thanks

Hi.
I´m trying to develop a search engine where users could search not only individual

Hi,
It all started when I wanted to create a photography competition and forum
on my web site. I searched and searched for a program (script) on the web
that would help me.
I found one and paid $125.00 for it, but I am very unhappy with the way it
works. It is not very user friendly and I'm loosing potential members
because of it. I have asked the programmer to assist me in creating it the
way I want it, he said he would,
I have yet to see the updates I requested. So I've taken it upon myself to
create a script tailored to my needs.
I have written HTML, some JavaScript, and very little CGI. I thought I
could handle creating this script. I went to my nearest Barnes and Noble
and bought 5 books on PHP and MySQL. I have been reading them for 2 weeks
and doing the lessons in one of the books until I'm bleary eyed. I have a
basic understanding, but I don't know where to begin.
I'm looking for someone with a little patience, who can get me on the right
path and guide me through. I don't know what I can give you in return...we
can talk about it if you're interested.

Cold Fusion, as far as I'm concerned, stinks. However, I have been involved
in porting a website from Cold Fusion to PHP and during this
transmogrification, I've come across something I'm not sure how to emulate
in PHP. Perhaps if there are any CF/PHP gurus out there, they can help me
out.
The tag I am talking about is <CFHTTP>. This tag allows you to emulate the
posting of a form, but also allows you to capture the results of the post.
There are a couple of forms written in CF that connect to the merchant
account, check a credit card, for example, and then wait for the
approval/denial response.
Is there anything in PHP that can do this same kind of thing? Any help
would be appreciated.
Best regards,

Google for something called PostToHost I wrote ages ago. Lots of
variations of that around. Basically you just fsockopen() to the site in
question and fputs() your request and POST data and then fgets() the
result.

I have need to be able to replace text within a string to turn it into a
link. In other words, I might have a phrase lik:
"blah, blah, blah, please visit my site at www.mysite.com. blah,
blah,blah".
I need to have the string converted to "blah, blah, blah, please visit my
site at http://www.mysite.com. blah, blah,blah". The link might have more
than 3 sections and won't necessarily end in .com (.net,.com.nl, etc.).
Here is what I have been testing (then I get stuck):
$myLink = "Please visit my web site at www.mysite.com. You will be glad you
did!";
$repLink = preg_replace("/(www.)/i","<a href=http://\\1",$myLink);
which yields
Please visit my web site at <a href=http://www.mysite.com. You will be glad
you did!
What I would need is
Please visit my web site at <a
href=http://www.mysite.com>www.mysite.com</a>. You will be glad you did!
To be truthful, pattern matching is giving me migraines! Programming has
always been natural to me (32 years of it), but this challenge (eregi,
preg_match,etc.) is making me crazy! Can someone recommend a good tutorial
or book on this subject?
Thanks!

Hi,
If I have en ENUM column in a mysql table, can I leverage
this through PHP to restrict user entry with a list?
Other option that I have is to create a lookup table, or
use an array.

You'll need to adapt this for your own use, but hopefully you'll get the
general idea.
