Re: [PHP] Setting up a new box from scratch?
Brian Dunning wrote: Hey all - I have an unused Pentium box here, recent, well loaded with RAM and HD. I want to turn it into a LAMP box. Never done that before; is there a preferred one-stop-shop installer CD or anything (easy - knock on wood)? It would be nice to end up with some kind of decent web GUI for admin. As others have responded, any linux distribution will come with packages to install the different components of LAMP. The 'easy' part depends on which distribution you choose, and how it does the install process. Most people recommend Madrake (now called Mandriva), Fedora (RedHat) or SuSE. Ubuntu is another one I see mentioned quite often. I would recommend you that you give the 'LiveCD' versions of these distributions a try before you decide to install one permanently. I've heard from other users that ubuntu's install process is very easy, but of course, YMMV. Also note that almost all of the distributions I mentioned here are designed for desktop use, which means that unless you customize the install, you will get a complete desktop system (including X, and one of KDE or Gnome). This is fine if you want to use the PC as a workstation from time to time. However, if you just want it to be a server (ie, no monitor, no keyboard, just plug it into the network) then you will have to customize the install process to uncheck those items that you will not need (like X, for example). For your other part -- webmin is a great utility for managing servers if you are uncomfortable with the shell. Your distribution will probably have a package (or RPM) for it, so just install it as per your distribution's install process.

Use call_user_func(). Simple example:

function x2() { print 'x2'; }
$x = 1;
call_user_func('x'.$x);
$x = 2;

[PHP] About Get_meta_tags()
Hi, All, Sorry to trouble you, but I really can not handle this problem now. I want to call get_meta_tags() function to get meta-tags which site I want to know. I searched usage and I did like this: ?php // Call get_meta_tags to fetch meta_tags in brackets. $tags = get_meta_tags(http://www.example.com/;); //Echo meta content print $tags['keywords']; ? But an errors occurred when the page run. Some information liked this: Warning: get_meta_tags(): php_network_getaddresses: gethostbyname failed in d:\apache\htdocs\meta_tag.php on line 3 Warning: get_meta_tags(http://www.pconline.com.cn): failed to open stream: No such file or directory in d:\apache\htdocs\meta_tag.php on line 3 My server is Apache 1.3.27 and PHP4.4.0 that run in Windows 2000 server.

As a result, it can't connect to the site and open a file stream to read the page you want to get the meta tags for, which is what the second error is about. I would suggest getting up a command prompt on the machine you are using (if this is possible) and seeing if you can resolve the domain manually by running 'nslookup pconline.com.cn' (without the quotes). If you can't, then there's almost certain a problem with one of your DNS resolvers, as I can resolve the hostname from here.

Re: [PHP] Re: dynamically selecting a function
hmm, there is an intresting way that AFAIK only exists in PHP which is the
variable variable and variable function.
That is you could have a string to be a function name and then make the call
with it in the following manner:
$step=1;
$func_const_name=step;
$dyn_func=$func_const_name.$step;
and then the function call would look like
$dyn_func(); // which would result in step1();
How about that? isnt it so beautiful? God Bless ZEND

[PHP] Inherit Methods
Is it possible to run inherited methods in the scope of the child class?
In my case I have an abstract class called 'Company' and some child
classes. There is a non abstract function in 'Company' which prints
'$this-phoneList'. That function should be the same to all child
classes, without rewritting it in every class.
I call the printing method via the child class like
$childObject-printPhoneList();
The call seems to be handed over to the parent class 'Company' which is
fine. But the $this points to the phoneList of the abstract parent
class. So the phoneList in the abstract class seems to be unset, since i
have set the phone list in the child class.
Here's a short example, showing what I mean:
?php
abstract class AbstractClass {
private $var;
public function printVar() {
echo('var: ' . $this-var . 'br');
}
}
class ConcreteClass extends AbstractClass {
public function __construct($var) {
$this-var = $var;
}
public function printVarChild() {
echo('var (child): ' . $this-var . 'br');
}
}
$cl = new ConcreteClass(15);
$cl-printVar();
$cl-printVarChild();
?
Output is:
var:
var (child): 15
Has anyone an idea how to print the $var of the child, without copying
the method in every child class?
thanks in advance,
Norbert

private then when yo execute printVar(), you aren't executed on parent
scope you are calling a copie on child scope, then you don't have
access to $var. Only when you use parent scope throw
parent::printVar() , you realy calling the parent class instance into
your child then print result.
Then when you want to have a variable for being used on a public

Before inserting it must verify if the data is unique. The php code

{
/* some more processing */

It's my understanding that a SELECT has a higher priority than an INSERT
on most MySQL setups.
I've ran into this problem on a site I hobby-code on also. It's my guess
that the write isn't hitting the DB in time for the second read to pick
it up, but that's a guess. As far as what to do about it if that's the
problem, I'll let someone else come up with that answer. ;) It's not
*that* critical in my app and it doesn't happen often enough to be a
real problem for me, but I would like to know if there's a way around it.

Re: [PHP] parallel execution of php code?
Hello Martin, Monday, August 8, 2005, 4:07:47 PM, you wrote: MvdB Now here is the problem: when the user enters the page, and MvdB directly refreshes the record is inserted twice Is is MvdB possible that both requests are processed simulatiounsly by the MvdB server (apache on linux)? And can I add something like a MvdB critical section or semaphore to overcome this problem. What data type does the execute function return? You're doing a loose type comparison between $rows and zero (== rather than ===), because it's a loose comparison a number of different results could equal zero in this case. For example if execute() returned false your code would assume an insert is required, which might not be the case. If you're using MySQL then you may want to look at using a different method for checking / inserting this data. Rather than a SELECT followed by INSERT you could use an INSERT IGNORE which won't duplicate data if it already exists. Or possibly REPLACE INTO - depends how you need this to work (i.e. retain the oldest copy of the data, or keep the newest). Look in the MySQL manual for those two functions for more info.

The problem with the approach above is that a race condition exists between the
check for the existence of the row in question, and the insertion of that row.
It's
possible that the two requests can come so close together that both of them
execute
their selects before either do their inserts. It's not very likely in the
simplest
cases, but as the amount of traffic (or the number of users you have who like to
quickly click refresh) increases there is a greater chance that this race
condition
will cause a problem.
In my opinion it's best to let your RDBMS handle this concurrency problem, since
it's best equipped to do that. Ideally you would be using some sort of
constraint
to prevent duplicate rows in your table...whether this is a primary key, unique
index, foreign key, etc. Inserting a duplicate row should result in an error
from
the database. In that case you can trap for the error in your PHP code (using
functions like mysql_error()) and handle it appropriately (for example,
displaying a
friendly error message, or simply ignoring the query).
Another approach would be to start a transaction with a high isolation level
before
executing the select, but to me this is less desirable because depending on your
database system it may cause contention problems if the entire table has to be
locked. Simply attempting the insert and catching the error should be much
lighter,
assuming it's possible to create the appropriate constraint in your database.

[PHP] Environment Variable contamination between vhosts - 1.3.33
Hi all, First time poster here so I apologize in advance for any gaffs. I've Googled, searched the archives and the FAQ but can't find anything close to what I'm experiencing. I have apache-1.3.33, mod_ssl-2.8.22 (with patches), php-4.3.2 (with patches, 4.4.0 tested as well), mod_perl-1.29-5 (with patches) running with the following additional modules -- mod_jk.c, mod_ssl.c, mod_php4.c, mod_perl.c, mod_setenvif.c, mod_so.c, mod_unique_id.c, mod_headers.c, mod_expires.c, mod_auth_db.c, mod_auth_anon.c, mod_auth.c, mod_access.c, mod_rewrite.c, mod_alias.c, mod_userdir.c, mod_actions.c, mod_imap.c, mod_asis.c, mod_cgi.c, mod_dir.c, mod_autoindex.c, mod_include.c, mod_info.c, mod_status.c, mod_negotiation.c, mod_mime.c, mod_log_referer.c, mod_log_agent.c, mod_log_config.c, mod_env.c, mod_vhost_alias.c, http_core.c all on RHEL 3.5. This server is handling a half dozen HTTP/HTTPS vhost pairs. Each vhost is running on a separate IP ala -- Listen 1.1.1.1:80 Listen 1.1.1.1:443 VirtualHost 1.1.1.1:80 ... /VirtualHost VirtualHost 1.1.1.1:443 ... /VirtualHost Listen 1.1.1.2:80 Listen 1.1.1.2:443 VirtualHost 1.1.1.2:80 ... /VirtualHost VirtualHost 1.1.1.2:443 ... /VirtualHost And so forth... We discovered a problem where the HTTPS environment variable was incorrectly being set to ON for normal HTTP requests for one of our vhosts running SquirrelMail. Further investigation revealed that a number of environment variables were being cross-contaminated between virtual hosts.

Re: [PHP] parallel execution of php code?
Check if you're using MySQL 4.1. If Yes use the subquery functionality.
So you could have your query as following:
Insert into sometable where not id=NULL and id=Select id from mytable where
bla like 'some pattern';
Not really sure if it would work thogh. Havent tried it yet.

Does anyone have any ideas about this?
Yes, two of the top of my head.
1. You can send the session variable to the client along with the script.
ex.
function doSomething()
{
sessVar = ?php print($_SESSION['variable']); ?;
// Do some stuff.
}
Of course, sessVar won't be updated if the session variable changes
unless the script is reloaded.
2. My favorite, but probably overkill. Write a php page that outputs
the session variables (as XML would be cool). Then use xmlhttprequest
to retrieve them from javascript (Google AJAX for more information).
Hope this helps,

I tried adding E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_WARNING, E_COMPILE_ERROR and so that whenever they occur, it will log itself to a log file. Another question related to that is how do I log a timeout error for the fopen() function?

[PHP] Possible to read JavaScript results into a string?
I have an external JavaScript that I use on several of my sites. It
returns a web counter and does some other logging. It's accessed like
this:
script language=javascript src=http://www.mydomain.com/log.js;/
script
No rocket science there, this is common and it works great. That call
returns a block like this:
document.write('a bunch of html')
What I want to know is: is it possible to retrieve the above
outputted code into a string, rather than outputting it directly to
the browser? Nothing I've tried works, and I also tried this using a
Google AdSense call to make sure there was not a problem in my
JavaScript. Here's what I tried and what happened:
?php
$x = file_get_contents('http://www.mydomain.com/log.js');
// also tried urlencode() but that did not help
?
The result:
Warning: main(http://www.mydomain.com/log.js) [function.main]: failed

[PHP] set variables based on HTTP_HOST
Is this potentially bad, security wise, to do something like this? Can
you guys recommend any way to tighten this up a bit or do this sort of
thing better/more eloquently?
?
$Host1 = array ('name1.host.com');
if (in_array ($_SERVER['HTTP_HOST'], $Host1))
{
$HeaderImg = /headers/name1_header.gif; // define graphic
$SiteCSS = /css/name1_css.css; // define css
}
$Host2 = array ('name2.host.com');
if (in_array ($_SERVER['HTTP_HOST'], $Host1))
{
$HeaderImg = /headers/name2_header.gif; // define graphic
$SiteCSS = /css/name2_css.css; // define css
}
$Host3 = array ('name3.host.com');
if (in_array ($_SERVER['HTTP_HOST'], $Host1))
{
$HeaderImg = /headers/name3_header.gif; // define graphic
$SiteCSS = /css/name3_css.css; // define css
}
$Host4 = array ('name4.host.com');
if (in_array ($_SERVER['HTTP_HOST'], $Host1))
{
$HeaderImg = /headers/name4_header.gif; // define graphic
$SiteCSS = /css/name4_css.css; // define css
}
else
{
$HeaderImg = /headers/main_header.gif; // define graphic
$SiteCSS = /css/main_css.css; // define css
}
?
link rel=stylesheet href=? echo $SiteCSS ? type=text/css /
img src=? echo $HeaderImg ?
The idea is to use this in the global header of a site that may be
invoked through up to 20-30 different third level subdomains, for the
same content. Standard stuff, one site, one set of tools to run it,
but each subdomain's slightly unique content pulls based on host.

Re: [PHP] Logging fatal errors and timeout

$_SERVER is, thankfully, _mostly_ populated by the web server, not the
client. HTTP_HOST certainly falls into this category. The only thing
you probably shouldn't do is rely on it always being there, so have
some catch-all set of headers / css if it's not set (mind you, if that
happens you've got a bigger problem on your hands! but it'd stop your
site breaking).
JS ?
JS $Host1 = array ('name1.host.com');
JS if (in_array ($_SERVER['HTTP_HOST'], $Host1))
JS {
JS $HeaderImg = /headers/name1_header.gif; // define graphic
JS $SiteCSS = /css/name1_css.css; // define css
JS }
Why are you creating lots of arrays and then using in_array to check
them? Just seems a little pointless in this instance as it gives you
no real benefit - comparing a one element array against a variable is
just... well.. comparing a variable with a variable! So why not do
that? Perhaps a switch block would serve your needs better?
switch ($_SERVER['HTTP_HOST'])
{
case 'name1.host.com':
$header = ..
break;
}
etc - then you can combine multiple hosts into one section and have a
default set at the bottom.
Best regards,
Richard Davey

RE: [PHP] currency class?
Have you ever considered using the Java class within PHP using something like the PHP-Java bridge? Here is a link for the bridge, PHP can call the Java objects natively. It's pretty cool. http://php-java-bridge.sourceforge.net/ I would use the bridge in a few situations: 1. The Java classes do a lot of under the hood things that are to slow in PHP or PHP is unable to accomplish the task 2. The PHP class that does the same thing as the Java class is unwritten and would require a lot of work to port it to PHP. If this is the case and it might be easier/cheaper to just use the Java class Nate Tobik (412)661-5700 x206 VigilantMinds -Original Message- From: Jon Hill [mailto:[EMAIL PROTECTED] Sent: Monday, August 08, 2005 11:22 AM To: php-general@lists.php.net Subject: [PHP] currency class?

[PHP] lack of understanding of sessions
Hello to all,
I think, I have a basic problem of understanding sessions and the
storing of variables in sessions.
I have a simple script I tested on 3 Apache-servers, one with PHP 5.0,
one with 4.3.10 and one with 4.0.6.
I have to develop for the 4.0.6 !!! server.
The output is different for every server.
All servers have session.auto_start off (irrelevant, cause I start the
session myself?) and session.use_cookies on
The PHP4-servers have register_globals on, on the PHP5 it is set to off.
My script is as follows:
session_start();
$test = ;
if (!isset($HTTP_SESSION_VARS['test'])) {
$test = test;
$HTTP_SESSION_VARS['test'] = $test;
echo if, test: . $test . br;
echo if, sesstest: . $HTTP_SESSION_VARS['test'] . br;
} else {
$test = $HTTP_SESSION_VARS['test'];
echo else, test: . $test . br;
echo else, sesstest: . $HTTP_SESSION_VARS['test'] . br;
}
echo test: . $test . br;
echo sesstest: . $HTTP_SESSION_VARS['test'] . br;
$test2 = ;
if (!session_is_registered('test2')) {
$test2 = test2;
session_register('test2');
echo if, test2: . $test2 . br;
} else {
echo else, test2: . $test2 . br;
}
echo test2: . $test2 . br;
When I call the script for the first time the output is:
if, test: test
if, sesstest: test
test: test
sesstest: test
if, test2: test2
test2: test2
on all servers.
Additionaly I get a warning for the session_register-part on the
PHP5-server. Thats ok.
But when refreshing the script, I get different output:
PHP5:
else, test: test
else, sesstest: test
test: test
sesstest: test
else, test2:
test2:
That's, what I would have expected.
PHP4.3.10:
else, test:
else, sesstest:
test:
sesstest:
else, test2:
test2:
I don't understand, why the variables seem to be empty.
PHP4.0.6:
if, test: test
if, sesstest: test
test: test
sesstest: test
else, test2:
test2:
I don't understand, why it won't go to the else in the
HTTP_SESSION_VARS-part.
In the session_is_registered-part, the var seems to be empty, too. Why?
I don't want to make use of the register_globals on, so think I should
prefer the HTTP_SESSION_VARS-part.
But what do I get wrong?
It would be very, very nice of you to explain it to me or to give me a
tip where to read more to approach my understanding.
Thank you in advance
Sabine

Dump out the session contents and see what's in there (if anything): print_r($_SESSION); Equally, dump out the cookie super global to see if the session cookie even got set print_r($_COOKIE); Or use the Web Developer extension for Firefox and Display cookies after the first page load - you should see the PHPSESSID cookie in existence. If not, that's the problem. If so, what does it say? S In the session_is_registered-part, the var seems to be empty, too. Why? Because even 4.0.6 shouldn't be using that function. If you want to check for the existence of a variable, use isset().

[PHP] A bug with RecursiveIteratorIterator?
I'm trying to extend the RecursiveIteratorIterator class, to limit which
children it recurses through.
The documentation here:
http://www.php.net/~helly/php/ext/spl/classRecursiveIteratorIterator.html
says that there is a ahapublic method callHasChildren(), which I figured
was a good place to start. It seemed like it made sense, except for the
fact that that callHasChildren() does not exist. Overloading the
function does nothing, and instantiating my extended object, then
manually calling callHasChildren() results in a method not found error.
Call to undefined method RecursiveIteratorIterator::callhaschildren()
I'm including my complete extension class below
Thanks,
Chris
class CPage_TreeMenuIterator extends RecursiveIteratorIterator
{
function __construct(CPage_Node $it)
{
parent::__construct($it,RIT_SELF_FIRST);
}
function callHasChildren()
{
echo CPage_TreeMenuIterator::callHasChildren();br /\n;
return parent::callHasChildren();

[PHP] Re: Error Suppression with '@'
my guess is that he is just trying to avoid errors in case the variable is not an actual array. arrays can easily be tested for by using: is_array( $myarray ); another way to manage arrays is to initialize them before you do anything with them. i.e.: $myarray = array(); this way if you need to call an array specific function which would normally throw an error because it's expecting an array as an argument, it won't choke. everyone is entitled to their own opinion, but i would just call suppressing errors on EVERY array function just plain lazy and very poor coding practice.

your out on the bleeding edge so to speak - not many people have
played with
this stuff yet - alot will depend on the php build your using - best
bet is to try the
latest RC of 5.1 and see what that has in it I have a felling you
will
have to make a bit of use of the following funcs (and maybe even the
reflection API)
to figure out _exactly_ what is available in your build:
http://php.net/manual/en/function.get-declared-classes.php
http://php.net/manual/en/function.get-declared-interfaces.php
http://php.net/manual/en/function.get-class-methods.php
Thanks for the response. I'm really in love with most of the SPL stuff,
it's most unfortunate that some parts aren't ready yet. Upgrading would
be OK for my test server, but I was hoping to put this code on a PHP
5.0.3 server (upgrading there is an option, but a very undesirable one).
I'll look into precisely what is working on my 5.0.3 development server
at the moment. Any ideas if this functionality is likely to change?
Right now I'm specifically looking the Iterator and RecursiveIterator stuff.
I'll explain my precise situation in more detail in the hopes that
someone can make some suggestions or point out another way I might be
able to do this without filtering the RecursiveIterator.
I'm essentially storing the navigation of a Website in an object tree.
The root node (Home) has children, each of those has children, etc. My
tree definition file (an include that uses method calls to the CPage
object) creates the tree, and assigns different target areas for the
navigation to appear in.
So one CPage_Node might reside in the Top target, but send it's children
to the Left target. and One of those children might Send *it's* children
to the Tab target, while the rest jsut send theirs to the Left target.
So, for each target that is a Tree (displays a tree structure) I
Recursively Iterate the Full page tree, starting at the Root Node point,
but I have to stop displaying children that are being shown in another
target.
I can get it to work with the follwing code (using the
RecursiveIterator, but not the RecursiveFilterIterator)
$iTarget = $oPage-GetMenu(CPAGE_TARGET_LEFT)-GetTarget();
foreach($oPage-GetMenu(CPAGE_TARGET_LEFT)-GetRecursiveNodes() as $oNode)
{
if($oNode-GetTarget() != $iTarget) continue;
// Display the node here
echo str_repeat(' ',$oNode-GetLevel()),$oNode-GetName(),\n;
}
Thanks,
Chris

Re: [PHP] oci8 recursive call in log
It seems to be that last line of your code which is causing the error. I've
no idea why though.

Re: [PHP] set variables based on HTTP_HOST
Hi!

Why are you creating lots of arrays and then using in_array to check
them? Just seems a little pointless in this instance as it gives you
no real benefit - comparing a one element array against a variable is
just... well.. comparing a variable with a variable! So why not do
that? Perhaps a switch block would serve your needs better?
I took your advice and put this up--any thoughts or advice would be
appreciated. Is the switch setup below the sort of thing you were
talking about? I altered it slightly overall to set a specific header
file, instead of a graphic, which is more useful.
?
// header generation script
// define path to includes header folder where
// include files live
$includepath = '/home/user/public_html/inc';
(( would be in a global include file, just here for clarity ))
// see what host is invoked
switch ($_SERVER['HTTP_HOST'])// check hostname
{
case 'domain.com':// define host
$Header = '/inc/main.header.inc'; // define header file
break;// next
case 'www.domain.com':
$Header = '/inc/main.header.inc';
break;
case 'host1.domain.com':
$Header = '/inc/host1.header.inc';
break;
case 'host2.domain.com':
$Header = '/inc/host2.header.inc';
break;
case 'host3.domain.com':
$Header = '/inc/host3.header.inc';
break;
case 'host4.domain.com':
$Header = '/inc/host4.header.inc';
break;
case 'host5.domain.com':
$Header = '/inc/host5.header.inc';
break;
// etc., etc.
default:
$Header = '/inc/illegalhost.header.inc'; // define header
}
// call the include header file for that host
if (file_exists($includepath/$Header)) {// include valid?
include stripslashes($includepath/$Header); // yup, include
} else {
echo FAILURE MESSAGE OF SOME SORT; // nope
exit;
}
?
(rest of page)
I figure I can get a regexp in there somehow so I don't need two
entries for the main domain.com and it's www c name, either... need to
add that.
I'm also sort of paranoid about unchecked includes in PHP and getting
compromised--is doing a check like I am here for the include file's
existence worthwhile or even useful to protect against possible
problems?
thanks,
Joe

[PHP] Re: Logging fatal errors and timeout
Thanks. How do I override PHP settings using .htaccess? Hello RPG, You cannot catch Fatal run-time errors with that method of error handling. The error has occurred before the script settings have had a chance to be picked up. Check to see if your host allows you to use .htaccess settings to over-ride PHP ini settings - for trapping Fatal run-times on a shared server that's most likely your only option. I've seen some hosts dump PHP errors to an error_log in the same directory as the script that caused the error. This might be an option (although not very secure, it's better than displaying the error across the middle of your site) Best regards, Richard Davey -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You're not doing an un-checked include - it's definitely checked.
You've pre-defined the $includepath at the start of your script, so
no-one can over-write this. You've forced $header to be one of the
switch options and *nothing* else. So those two things are certainly
clean.
If someone manages to inject bogus variables into your
$_SERVER['HTTP_HOST'] element then you've got bigger things to worry
about than your code :) (i.e. someone has compromised your server) but
with your switch block and pre-set values even if they had managed
that, you'd still only ever include a valid header.
You have to draw the line somewhere with security - nothing will ever
be 100% safe because there are so many chains in the loop (firewall,
network, server, apache, php, etc). I would say that as it stands
you've done the best you can for this little section of code, but
perhaps some others might post more ideas if they have them.

Security-wise, you can't count on $_SERVER['HTTP_HOST'] , it is passed
to PHP by Apache, but Apache is just passing through the user-supplied
Host header.
So don't depend on that for any security related information (like
restricting logins), but, if it's jsut page layout, and they are all
similarly accessible site, that shouldn't be a problem.

[PHP] Re: parallel execution of php code?
Martin van den Berg [EMAIL PROTECTED] writes:
I have this piece of php-code which inserts data into a database.
Before inserting it must verify if the data is unique. The php code
looks something like:
$query = SELECT id FROM mytable WHERE bla LIKE . $x .;
$rows = execute( $query )
if ( $rows == 0 )
{
/* some more processing */
$query = INSERT INTO mytable .. etc etc
execute( $query )
}
Now here is the problem: when the user enters the page, and directly
refreshes the record is inserted twice Is is possible that both
requests are processed simulatiounsly by the server (apache on linux)?
And can I add something like a critical section or semaphore to
overcome this problem.
There are 2 ways to handle this problem -
- create a UNIQUE index on whatever columns you want to be unique in
your database. This way, when the user refreshes the page, the second
insertion will fail. Of course, it means you will need to handle the
duplicate key error that the database will throw up gracefully.
- When the page loads, check if the $_SESSION[_insert_success] is
set. If not, then do the insert part and if the insert is successful,
set $_SESSION[_insert_success]=true. If the variable is set, then
do not do the insert part , simply display the page again.
