Predefined variables with php code

for example:
form1.html
<html>
<body>
<form action = "action.php" method = "post">
please select comany：
<select name="company" >
<option value="company1">company1
<option value="company2">company2
<option value="company3">company3
</select>
<input type="submit" value="提交">
</form>
</body>
</html>
action.php:
$query = "select * from company_table where company_name = $_POST[company]"
I don' know whether pass $_POST[company] is right or not.
who can help me?
thanks a lot!

Pls don't get confused, to post data from one page to other page you must use either POST/GET methods..once you post your data from one page to second page...in that second page instead of directly using those post data it is always better to validate that data.. say if your data contains single & double quotes then you must add slashes(\) .. there should be some mechanism to prevent malicious data getting inserted into your DB..

Accessing session variables with php

I am trying to access the session variable $_SESSION['MM_Username'] in one of my php pages, but it is somehow showing empty (i.e it does not contain the username that was entered during login).
I checked and confirmed that my login.php function is properly setting the MM_Username session variable by echoing it from the login function.
So why can't I read it from another php file in the same session? Do I need to do something else before the session variables can
be properly read from any php file in the same session? Any help would be appreciated.

Here is a test code I am using to access the session variable $_SESSION['MM_username'] from the php page test.php. But it is not working.
I get an empty string all the time for $username. Can any one see something wrong with this code?
<?php require_once('Connections/MyTestingConn.php'); ?>
<?php session_start(); ?>
<?php
$username = "-1";
if (isset($_SESSION['MM_username'])) {
$username = $_SESSION['MM_username'];
echo $username;
else
echo "Eror: can not access session variable";
?>

A difficult problem with php code and sql code

it's good place to visit(Paged Result Sets with PHP and Oracle)
http://www.oracle.com/technology/pub/articles/oracle_php_cookbook/fuecks_paged.html
maybe below part php code could not be used in above address's php code.
if((isset($l_company) and $l_company != $rows['COMPANY']) or empty($stmt) and empty($total_pages) ) {
echo "<tr bgcolor='#CCFFCC'>";
echo "<td colspan= 3 align='center'>".$l_company."</td>";
echo "<td >".$totalcomany." </td>";
$totalcomany = 0;
echo "<td > </td>";
echo "</tr>";
$l_company = $rows['COMPANY'];
because the same company in one page could calculate sum while if
the same company in two pages could not do that.
and what do you think of ?
thanks !

Hi,
this is because your sql-statement selects only the rows, you need to build this one page.
Neither php nor the given result from your query knows about data wich will be part of the result of another page.

Problem with php code. Please help!

Hello!
I'm using the following syntax to bring content into my
websites' layout template:
Code:
<?php //check in the root folder first
if(file_exists('./' . $pagename . '.php'))
include './' . $pagename . '.php';
//if it wasn't found in the root folder then check in the
news folder
elseif(file_exisits('./news/' . $filename . '.php'))
include './news/' . $pagename . '.php';
// if it couldn't be found display message
else
echo $pagename . '.php could not be found in either the root
folder or the news folder!';
} ?>
What it's essentially saying is, if you can't find the .php
file in the _root folder, look for it in the /news/ folder.
It works perfectly if loading something from the _root folder
but I get an error if I need to bring something from the /news/
folder.
Can anyone see any potential problems with my code?
Thank you very much and I hope to hear from you.
Take care,
Mark

I've never seen the code written like that before, but I'm
assuming it's
legal?
Perhaps try:
<?php
$newsroot = $_SERVER['DOCUMENT_ROOT']."/news";
if (!file_exists("$pagename.php")) {
elseif (!file_exists("$newsroot/$pagename.php")) {
else
Or the other thing you can try is replacing the elseif
statement with:
elseif (!file_exists("news/$pagename.php"))
If not - I'm sure Gary will be on here soon...

Help with php code

Using DW CS4
Have a page with a select that is populated from a recordset that lists products and i am trying to have the select show certain products as being SOLD OUT!
Here is the code i have
<?php
/*START_PHP_SIRFCIT*/ if
($row_rs_options['OptionPriceincrement']!="0"){ ?>
<option value="<?php echo
$row_rs_options['ProductOptionID']?>"><?php echo
$row_rs_options['OptionName']?> $<?php echo
$row_rs_options['OptionPriceincrement']; ?></option><?php } else
echo'<option class="style1" value=""><?php echo
$row_rs_options[\'OptionName\']?> ITEM SOLD OUT!</option>'
/*END_PHP_SIRFCIT*/ ?>
If my else statement is triggered, i want the select option to show the OptionName where the OptionPriceincrement is == to 0 and also the text ITEM SOLD OUT!
With the code as i have it, only the ITEM SOLD OUT! shows in a browser.
You can see this here http://www.comfycampers.info/products.php
Go to Tour Bon Ton Roulet and view the select
thanks for your help,

<?php /*START_PHP_SIRFCIT*/ if ($row_rs_options['OptionPriceincrement']!="0"){ ?>
<option value="<?php echo $row_rs_options['ProductOptionID']?>"><?php echo $row_rs_options['OptionName']?> $<?php echo $row_rs_options['OptionPriceincrement']; ?></option><?php }
else { ?><option class="style1" value=""><?php echo $row_rs_options['OptionName']; ?> SOLD OUT!</option>

Hey,
I'm French so i'll try to explain in my best english.
I had the same problem. And i solved it.
In fact i change the dll because the one which php install give us is not compatible.
I choose the one which is provides with wampserver 2.0i.
php_oci8_11g.dll
with instantclient_11_1g
Next i'll create environnement variables
NLS_LANG=FRENCH_FRANCE.WE8ISO8859P15
TNS_ADMIN=d:\oracle
and in path variable add the way to the instantclient11_1
D:\oracle\instantclient_11_1
Then i restart the server and lucky all services start and run perfectly.

Creating a session variable with PHP

Can anyone offer me a PHP script that creates a session
variable? The Dreamweaver CS3 Help documentation offers coding
samples for ColdFusion and ASP but not for PHP. I tried this
without success:
"$_SESSION['usermail']= $_POST['sub_email'];" in which I am
trying to capture an email address from a form and save it to use
in a confirmation email to a new subscriber. Any help would be
sincerely appreciated.
[email protected]

I use this -
<?php
if (!isset($_SESSION)) {
session_start();
?>
at the top of the page, and then this within the code block
where you are
processing the form's data -
$_SESSION['usermail']= $_POST['sub_email'];

Problem with PHP, CSS & Code Navigator in CS4

Hi,
I've got al little problem with code navigator. To show the problem, I created this 3 files:
test1.html
The CSS-Definition is defined static, with simple HTML.
<html>
<head>
     <style type="text/css">
          @import "test.css";
     </style>
</head>
<body>
      <p>Hello World</p>
</body>
</html>
test2.php
The CSS-Definition is defined dynamic, with PHP-Code.
<html>
<head>
     <style type="text/css">
          <? echo "@import \"test.css\";\n"; ?>
     </style>
</head>
<body>
      <p>Hello World</p>
</body>
</html>
test.css
The CSS-File which is imported in test1.html and test2.php
p {
     font-size:20px;
The Problem in Dreamweaver CS4
When opening the test.html - File in Dreamweaver CS4, I can easily see the CSS-Definition of the <p>-Tag in Code Navigator. To edit these definition I can simple open the test.css by clicking on the definition in Code navigator. For a complex webpage this is a greate feature. Sadly, this does not work, when I open the test2.php. Although when going to Live View and selecting the <p>-Tag I can see the CSS-Definition and the file in which it is defined in Code Navigator. But by clicking on the definition the test.css DOES NOT OPEN!
Has anybody a solution? Because many of our projects have dynamic CSS-Definitions, it would be a shame, if this would not work.
Tanks for help! :-)

I've done some testing, which might point you in the direction of an interim solution.
This is the code for related_files.php:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Related files test</title>
<?php include('include.css'); ?>
</head>
<body>
<p>This is a paragraph.</p>
</body>
</html>
This is the code for include.css:
<style type="text/css">
p {
     font-family:"Trebuchet MS", Arial, Helvetica, sans-serif;
     color:#F00;
</style>
Note that the include file contains the opening and closing style tags.
By including your styles like this in a PHP include file, Dreamweaver applies the CSS in Design view (you don't need to turn on Live View). Holding down the Alt key while clicking in Design view brings up the Code Navigator with all the details of the CSS. The one missing link in the chain is that clicking the style selector in the Code Navigator does not open the CSS file. However...
The file that contains the CSS is listed in the Related Files toolbar, so you can edit it in Split view, and see the results in Design view in exactly the same way as with an HTML page and ordinary style sheet.
As I say, not the full solution that you wanted, but it might be something worth experimenting with.

Variables with upload()

hello!
like the help demonstrate ist, i've this code
var variables:URLVariables = new URLVariables();
variables.date = new Date();
variables.ssid = "94103-1394-2345";
request.method = URLRequestMethod.POST;
request.data = variables;
referenzen[ladezaehler[0]].upload(request);
but how can i get reed the variables with php? the picture i want to upload is uploaded, so there is no problem with the connection ore something else
thank you for helping me

Hey!
Try this:
var variables:URLVariables = new URLVariables();

loader.load ( request );
Hope that helps you.

How Can i use the key file Generated by RSACryptoServiceProvider to encrypt with php?

I need to be able to encrypt data in PHP using a public key generate by .NET(RSACryptoServiceProvider). I will then decrypt the data later in C# using the private key.

As you see this code snippet is a xml format private key. at .net platform,which can use encrypt or dencrypt.
i have try the Extension Crypt RSA ( http://pear.php.net/reference/Crypt_RSA-1.0.0/elementindex_Crypt_RSA.html ) to help me encrypt data by php.but it haven't return a currect result. the data encrypted by php cann't dencrypt by c#.
does the RSA algorithm provider by Crypt_RSA can give a stand result as c#?
BTW :i just use the xmlkeystring like this.

thank you for your reply, i also found this article by google.but this does not meet scene, thank you all the same.
i have already solved the problem now,i'd like to post the Solution .infact it's so easy to use rsakey file generated by .net .

Error bind variable with "like %" clause ?

Hello everybody;
I would like to know how to do a like clause to bind variables, with this code i obtain 'ORA-00933: SQL command not properly ended' error
v_query:= 'UPDATE ' || collection(i) ||' SET REF_PLAN=:quatre_champ WHERE FAM_SIM like ''%'':prem_champ''%'' AND PRISE_V1P like ''%'':deux_champ''%'' AND BROCHE_V1P like ''%:trois_champ%''';
                              EXECUTE IMMEDIATE v_query USING quatre_champ,prem_champ,deux_champ,trois_champ;Maybe my " ' " are in a bad positions ?
Thanks for your help, regards.

Hi,
try this
v_query :=
         'UPDATE '
      || collection (i)
      || ' SET REF_PLAN =:quatre_champ WHERE FAM_SIM like'|| '''%:prem_champ%'''
      || ' AND PRISE_V1P like' || ''' %:deux_champ%'''
      || ' AND BROCHE_V1P like'||''' %:trois_champ%;'''
Of course not tested
Any efforts to give sample data and help us recreated the problem will be appreciated.

Preview of frameset in combination with php fails

Hi,
I've set up a testserver (Apache with PHP5 on Windows XP) on
my local machine.
Previewing pages (with and without PHP-Code) works well, but
if I try to preview a page with a frameset, DW tells me that it
cannot display framesets because the testserver is remote and asks
me if it should do local preview.
(Local preview doesn't help me if I want to preview framesets
that include frames with PHP-Code ...)
In site setup I defined the testserver as "local/network".
What do I do wrong?

Hello,
If I remember correctly, the localhost addon is only needed for PDA deployment. Since MTT is laptop only, you should not deploy it.
Deploying addons of any nature should be done in a second step in MI. You should deploy the application and then deploy the addons. One step installation has never been reliable.
Thank you,
Julien.

Having trouble with my PHP code. Appers to get stuck on a white page.

HI all,
I have just began having trouble with my PHP code. Was working before and haven't made any changes to the code since last time it worked.
What happens is after the form is submitted it goes to a white page (no text just all white page) and in the address bar it has the path for my php page. what supposed to happen is either it goes to a success page or a error page.
I've had a problem where the info entered is correct but was directed to the error page. i managed to fix that issue but i am puzzled what is happening to my php page now.
Mind you that i didn't write this code i just took over the responsiblities of this website and i am hopping that its a quick fix.
I appreciate any help you could give me. Thank you.
CODE:
<?php
   $to = '[email protected]';
      $from = '[email protected]';
        //Make sure we have some info posted from the form...
        if (isset($HTTP_POST_VARS)){
            //Clear the body of the message to be sent
            $body = '';
            //go through all POSTed variables sent
            while (list($key, $value) = each($HTTP_POST_VARS)){
    if($key <> "Submit" && $key <> "submit") {
     $body .= $key . ' = ' . $value . "\r\n";
            //Now building mail headers.....
            $headers = "From: ".$from."\r\n";
            //Mail message
            $success = mail($to, "Email Club" . date("m/d/Y"), $body, $headers);
   // CURL stuff.....
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_FAILONERROR, 1);
   curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
   curl_setopt($ch, CURLOPT_TIMEOUT, 4); //times out after 4s
   curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
             if ($success){
    //readfile('http://www.lvpaiutegolf.com/thankyou.html');
    curl_setopt($ch, CURLOPT_URL,"http://www.lvpaiutegolf.com/thankyou.html");
    header("Location:http://www.lvpaiutegolf.com/thankyou.html");
            else{
             // readfile('http://www.lvpaiutegolf.com/error.html');
     curl_setopt($ch, CURLOPT_URL,"http://www.lvpaiutegolf.com/error.html");

   // Output

Help with php session variables

I am using Dreamweaver 8 to set up a dynamic app with PHP and
MySQL. I want the code that the user logs in with ('UPN') to be
stored as a session variable so that recordsets on subsequent pages
can be set to display personalised data.
I have set the session variable like this: $_SESSION['UPN'] =
'UPN' (UPN is the name of the form textfield, also set as the
username for logging in)
On the data page, I have called the variable like this:
$query_Recordset1 = ("SELECT pupils.pupilID, pupils.UPN,
pupils.forename, pupils.surname FROM pupils WHERE UPN = '" .
$_SESSION['UPN'] . "'");
The recordset returns nothing- the dynamic table returns ony
the column headings (both as headings and immediately under where
you would expect the data to be).
Can anyone help?
Thanks

Your code assigns the literal string UPN to the session
variable. If
it's coming from POSTed form data, you'd need to do it like:
$_SESSION['UPN'] = $_POST['UPN'];
