You can insert a textarea into a page without a name and mozilla will work.
If the textarea is named have you tried this....

echo $_POST['textareaName'];

CF has an application scope - PHP does not.
the strength and simplicity of PHP stem from the decision to make/keep
PHP a "share nothing" architecture.

with regard to shoving stuff in the SESSION superglobal:

1. it not shared between requests by different users - meaning
that the SQL query you gave as an exmaple would still be run once
by every visitor and each visitor would have a copy of the
result set object.

2. performance-wise sticking objects in the session is possibly
something to be avoided is possible - storage and retrieval of 'complex'
structure (i.e. objects in this case) comes with a certain performance
penalty (you might want to consider using an array to store the query results)

3. you MUST load the class definitions of ALL the objects that are in your 
session
BEFORE you start the session.

Christopher Jordan wrote:

Hi folks,
I'm a ColdFusion developer, but I'm branching out into PHP because alot of my smaller clients don't want to pay for CF. Anyway, a bit of background: I've got a page that does a search on one of my tables. I'm using Justin Vincent's ezSQL (http://php.justinvincent.com) to fetch the result set into an object that can be referenced nicely. Here's what his example code looks like: // Select multiple records from the database and print them out.. 
          $users = $db->get_results("SELECT name, email FROM users");
          foreach ( $users as $user ){
                       //  Access data using object syntax
                      echo $user->name;
                      echo $user->email;
          }
So far so good. So I've got an iframe on the page which (I hope) will eventually display the results of the search. The user will then click on the search result for which they want to view the details, and the information from that row will be populated inside the main page (the one that houses the iframe). Hope that makes sense. Okay, so my trouble is that I don't know how to enable the page inside the iframe to have access to the result object created by Justin Vincent's nifty little class. In CF I can just say: session.oResults = queryname CF automatically returns any query as an object with the name of the query as the object name (i.e. queryname.MyIdField, or queryname.EmployeeNumber, etc.) Using a line like the one above (assigning the query object to a session variable) all of my subsequent requests would have access to that result set simply by using the object. I'm *sure* there's a way to do this in PHP. I'm just falling short of finding the answer. I've tried: $_SESSION["SearchResult"] = $db->get_results($query); But it doesn't seem to work. I may have some other problem using the object. I just re-read my error and it says: Fatal error: Call to a member function get_results() on a non-object in inventorymanager.php on line 93 hmm... I sure would appreciate a little guidence here. Even if my problem is with the way I'm using the object, is the idea of assigning that object to the session scope the right way to do this or is there a better approach. To that end, I suppose I'm looking for an idea of the best practice. Thanks!

use google, see where it gets you?

I searched for 'php pop3 connection'

and found this straight away:

I would take a look at the get() method - it might do what you want, or inspire

Leonard,

this is a mailing for helpinmg people understand PHP and
solve PHP problems.

the fact that you need a complete webbased interface to a container loading
algorythm does not really constitute a 'php problem'.

what you are asking for is, softly put, quite complex & rather specialized.
people have spent years developing software to this end ... the price you pay
for it is reflected in that. chances are it does not exist in the open source
arena. you might consider looking beyond php though, given that conceptually
the mathematics involved are probably above you (unless you major in mathematics
or something similar :-) there is little need to have such a tool written in
a language you [fully] understand. (I found at least one tool which had an ASP
api available for linking in a webbased interface).

HI all,

I am working on a project where it would be nice to be able to create
a load plan for a semi trailer or ocean container.  There are some
commercially available programs to do this in windows but nothing in
PHP.

Does anyone know of a PHP script that will do this?

Basically it needs to know the size of the trailer and the size of the
items being loaded and then it will go through and create a load based
upon the density of each piece and distribute the weight evenly across
the trailer and fill the trailer up.

Thanks,

Yes, there is.


$_SERVER['REFERER'] will give you the referer mosy of the time. More info

Hi Dave,

You can look for the value of     $_SERVER['REMOTE_ADDR'], and then you can
serve users as per your preferences.

REFERER is the URL the client came from though, not the local IP address of 
the client.  Methinks the OP wants REMOTE_ADDR.

That is why I said it would "give the referer most of the time". There is no
other way, at least that I am aware of, to accurately gain the referer of
the user each and every time.

Any external data introduced into a script can't be trusted... including
$_GET and $_POST

That doesn't mean they shouldn't be used... just used carefully

Also if you want to use the IP address maybe REMOTE_ADDRESS would be
favourite

I'm sure Jay is well aware of that issue - I'll expand the concept for you...

every freaking bit (as in 8 bits make a byte) sent to your script from a
user agent (e.g. your browser) cannot _really_ be trusted (what so f***ing 
ever).

BUT HTTP_REFERER is not what you want I think ... because that gives you the
domain/ip of the server which referred the visitor to your page and not the 
domain/ip
of the client.


consider that there might a better/safer solution at the level of the
webserver (e.g. virtual hosts combined with conditionally set env vars) or at
the level of the networking subsystem of your server (e.g. seperate interface 
for
local subnet traffic?).

also you might find something useful in the couple of IP related
functions I include below....



/* Determine if an ip is in a net.
 * E.G. 120.120.120.120 in 120.120.0.0/16
 */
function isIPInSubnet($ip, $net, $mask)
{
    $firstpart  = substr(str_pad(decbin(ip2long($net)), 32, "0", STR_PAD_LEFT) 
,0 , $mask);
    $firstip    = substr(str_pad(decbin(ip2long($ip)), 32, "0", STR_PAD_LEFT), 
0, $mask);

    return (strcmp($firstpart, $firstip) == 0);
}

/* This function check if a ip is in an array of nets (ip and mask) */
function isPrivateIP($theip)
{
    foreach (array("10.0.0.0/8",
                   "172.16.0.0/12",
                   "192.168.0.0/16") as $subnet)
    {
        list($net, $mask) = explode('/', $subnet);
        if(isIPInSubnet($theip,$net,$mask)) {
            return true;
        }
    }

    return false;
}

/* Building the ip array with the HTTP_X_FORWARDED_FOR and REMOTE_ADDR HTTP 
vars.
 * With this function we get an array where first are the ip's listed in
 * HTTP_X_FORWARDED_FOR and the last ip is the REMOTE_ADDR
 */
function getRequestIPs()
{
    $ipList = array();

    foreach (array('HTTP_X_FORWARDED_FOR', 'HTTP_FORWARDED_FOR', 'REMOTE_ADDR') 
as $key) {
        if (isset($_SERVER[$key]) && $_SERVER[$key]) {
            $ipList = array_merge($ipList, explode(',', $_SERVER[$key]));
            break;
        }
    }

    return $ipList;
}

/* try hard to determine whAt the users/clients public IP address is */
function getRequestIP($allowPrivIPs = false)
{
    foreach (getRequestIPs() as $ip) {
        if($ip && ($allowPrivIPs === true || !isPrivateIP($ip))) {

Yes, there is.


$_SERVER['REFERER'] will give you the referer mosy of the time. More
info
from TFM can be found here;

http://us3.php.net/reserved.variables

Header can then be used to redirect

header("Location: http://www.example.com/";); /* Redirect browser */.

'HTTP_REFERER'

 The address of the page (if any) which referred the user agent to
 the current page. This is set by the user agent. Not all user agents
 will set this, and some provide the ability to modify HTTP_REFERER
 as a feature. In short, it cannot really be trusted.

That would be something along the lines of:

preg_match("/^192\.168/",$_SERVER['REMOTE_HOST']);

I'm a little rusty on my regex, but that should do it.

REMOTE_HOST contains the resolved DNS name of an IP address.  This value is 
dependent on your web server doing DNS resolution (and most people configure 
it not to due to the speed impact).

REMOTE_ADDR contains the IP.

preg_match() probably does what you want.

Oops... REMOTE_ADDR should have been used.

No, it is not possible. These are browser based controls that are not
exposed to scripting of any type.

As far as I know, "AJAX" is just the use of the Javascript
XMLHttpRequest object to make HTTP requests of the server; it looks
like you have some AJAX framework that tries to automate things.  Can
you be more specific about what you're using?
