  Try to assign information that you extract from the database to a variable, then move this information to the next page by using the variable $_SESSION:

  @session_start ();

  if ("" == "")     {

  $variable = $row_rs_Lodge [GSG_URL'];

  $_SESSION ["Lodge_GSG_URL"] = $variable;

  }

  ?>

• Help with the session variable PHP CS5.5 - Please

  Hi all

  I am needing a little help with the help of a session variable, and I hope someone can point me in the right direction.

  I created a PHP page that uses the Dreamweaver 'User authentication' feature and the basics of this works very well, to direct a user to the correct page depending on whether they are or are not a valid user. I want to customize the page 'user valid' with people, user name entered in the authentication of the user table... a seemingly simple task using a session variable, but I just seem not to be able to make it work!

  The generated code for the AU on page 1 is the following:

  <? PHP

  Validate request to connect to this site.

  If (! isset {})

  session_start();

  }

  $loginFormAction = $_SERVER ['PHP_SELF'];

  If (isset($_GET['accesscheck'])) {}

  $_SESSION ['PrevUrl'] = $_GET ['accesscheck"];

  }

  If (isset($_POST['txtfirst_name'])) {}

  $loginUsername = $_POST ['txtfirst_name'];

  $password = $_POST ['txtsurname'];

  $MM_fldUserAuthorization = "";

  $MM_redirectLoginSuccess = "member_update.php";

  $MM_redirectLoginFailed = 'login.php ';

  $MM_redirecttoReferrer = false;

  @mysql_select_db ($database_panto, $panto);

  $LoginRS__query = sprintf ("SELECT firstname, name OF web_access WHERE firstname = %s AND family name = %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  $LoginRS = mysql_query ($LoginRS__query, $panto) or die (mysql_error ());

  $loginFoundUser = mysql_num_rows ($LoginRS);

  If {($loginFoundUser)

  $loginStrGroup = "";

  If (via PHP_VERSION > = 5.1) {session_regenerate_id (true) ;} else {session_regenerate_id() ;}

  Declare two session variables and assign them

  $_SESSION ['MM_Username'] = $loginUsername;

  $_SESSION ["MM_UserGroup"] = $loginStrGroup;

  If (isset($_SESSION['PrevUrl']) & & false) {}

  $MM_redirectLoginSuccess = $_SESSION ["PrevUrl"];

  }

  Header ("Location:".) $MM_redirectLoginSuccess);

  }

  else {}

  Header ("Location:".) $MM_redirectLoginFailed);

  }

  }

  ? >

  First of all, the text highlighted in red above seems to be setting the session variable that I need. Is this correct?

  If so, what is the code that I need to put on page 2 to use this session variable? or

  I have to do something else on the page 1 to correctly assign the session variable?

  Would be very grateful for your expertise

  Mark

  It seems that you put the columns incorrectly in the user authentication server behavior. This is the SQL query that checks the credentials of the user:

  $LoginRS__query = sprintf ("SELECT firstname, name OF web_access WHERE firstname = %s AND family name = %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  You are looking for first name and last name, while you should look for the user name and password of the user.

  $_SESSION ['MM_Username"] is a session variable that stores the login name of the user. To use it in a page, all that is needed is the page start with session_start(). You can then echo the value to display.

  If you want to display the person's true name, you must create a recordset in the second page, use of $_SESSION ['MM_Username'] to search for the first name and the patronymic. Alternatively, you can change the code like this (I copied only part of it):

  $LoginRS__query = sprintf ("SELECT firstname, surname OF web_access WHERE firstname = %s AND password is %s",

  GetSQLValueString ($loginUsername, "text"), GetSQLValueString ($password, "text"));

  $LoginRS = mysql_query ($LoginRS__query, $panto) or die (mysql_error ());

  $loginFoundUser = mysql_num_rows ($LoginRS);

  If {($loginFoundUser)

  $loginStrGroup = "";

  $row = mysql_fetch_assoc ($LoginRS);

  $_SESSION ['full_name'] = $row ["FirstName"]. ' ' . $row ['name'];

  If (via PHP_VERSION > = 5.1) {session_regenerate_id (true) ;} else {session_regenerate_id() ;}

  Declare two session variables and assign them

  $_SESSION ['MM_Username"] = $loginUsername;

  $_SESSION ["MM_UserGroup"] = $loginStrGroup;

  You can then use $_SESSION ['full_name'] in a page which begins with session_start().

• PHP Mail with session variables

  Here is the code for an email to collect page, which sends two session variables (email and postal code) to an email_sub.php page (data are inserted in MySQL). After submitting the form, I get the email_sub.php? page where this code works normally

  <? PHP echo $_SESSION ['email'];? >

  <? PHP echo $_SESSION ['postal code'];? >

  However, when the email is sent, the "subject" and the "To" is successfully sent, but not the variables $email and $zipcode.

  From:
  Zip code:

  If I hard code for values of and Zip, they appear in the email. It seems therefore that session variables are not available at the email_sub.php page.

  If anyone can point me in the right direction for a fix, I'd be very happy to suggestions.

  It seems that you do not use session variables when you send the mail:

  mail('[email protected], [email protected]',
  'Join Email List',
  "From: $email\r\n Zip: $zipcode");
  

  Change to this:

• How to add an extra session variable to authenticate the connection

  Hello

  IM totally new to php and dreamweaver develop a web application that uses the user name and password to authenticate the connection, and works very well. My question is, how do I add an extra session variable to capture another field in the users table for example type to redirect some pages based on the value of the type?

  If you're completely new to Dreamweaver and PHP, it sounds as if you're using Dreamweaver server behaviors. Take a friendly piece of advice and stop using the server now behaviors. They have been removed from Dreamweaver CC a couple of years because they use functions that had to be stripped on the next version of PHP. This version (PHP 7) was released in November. If you rely on Dreamweaver server behaviors, you are living on borrowed time. For a person to debut, it makes no sense to learn how to use a dead technology. The server behaviors work only in PHP 5. As soon as your server is upgraded to 7 PHP, you will have to start all over again. To understand the problem, see the following page in the PHP online documentation: PHP: Introduction - manual.

  If you want Dreamweaver to generate the code for you, you will need to use (paid-for) third-party extensions, such as those created by DMXZone or WebAssist. You can also learn how to write PHP code yourself. It is not as difficult as it sounds.

  To create a variable session, just to assign a value to an element in the superglobal array $_SESSION:

  $_SESSION ["$myvariable"] = "value";

  Session variables are available only on the pages that begin with session_start().

  I think that session is only valid for the base App., if you switch to a new app a new session is created.

  Problem solved.

• Can I use a username of the php session to select a mysql table?

  In my site, I have a situation where

  $_SESSION ['MM_Username"]

  will be the same name as a MYSQL table prepared.

  (There will be a limited number of users and tables)

  Instead of writing a long series of "else if" to deal with each user of each page, I want to use the $_SESSION ['MM_Username'] to point to the correct MSQL table.

  For example

  <? PHP $query_rstPalabs = "SELECT * FROM patricia WHERE YesNo > = 1";  ? >

  How can I replace the $_SESSION ['MM_Username'] for 'patricia' here in a way that the SQL would choose the table 'patricia '?

  Please be aware that I am not a professional designer and wading in the shallows of PHP/MSQL.  I use DW2004MX to help.
  Thank you.

  Smiffy47,

  Assign a variable with $_SESSION ['MM_Username"]. Call the variable in your query:

  Example:

  $user = $_SESSION ['MM_Username"];

  $user WHERE yesno >= 1" ; =""?>

  Be sure to use session_start at the beginning of your page so that you are allowed to call session variables in your application.

  This should be added before your declaration DOCTYPE (the very beginning of your page).

• Creating a connection with Session variables

  Hey everybody! I've never used session variables so I'm not sure how they work, so I have a simple question for their use with a login form!

  I created a small form of login in the top right of my Web page, and what I want to do is when the user connects, the newspaper in the form of skins and is replaced by 'Welcome (username)' and stays that way while browsing the Web site. I think it's simple to do, ive just never used before

  Here is my login information for the code: (note this div tag is inside a table, do not know if it matters)

  <div id="login">
        <form ACTION="<?php echo $loginFormAction; ?>" id="form1" name="form1" method="POST">
          <label for="U_name"></label>

  How do I filter the recordset based on the value of the session variable

  Each test returned correct results.  We checked one) your session variable is set correctly, b) the SQL statement is properly filtered by email, and c) the returned results are as expected.

• being lost ColdFusion session variables

  Okay, so when my users login I create session variables. one of them is the employee id. in my Application.cfc I have this at the top:

  < cfscript >
  myIdName = "My App";
  This.SessionTimeout = CreateTimeSpan ("0", "0", "45", "0");
  This. SESSIONMANAGEMENT = "YES";
  This. SetClientCookies = "true";
  this.setDomainCookies = "true";
  < / cfscript >

  I also put the timeout for sessions at 45 in the CFadmin too.

  After a successful login, I capture their session.employeenumber by is authenticating through our enterprise LDAP. no problem. Note: this app has run smoothly for 6 years now but recently something has gone wrong.

  on every page I reference a file in my application directory called "check_session.cfm" like this:

  "< cfmodule template="/myApp/Tags/check_session.cfm ">

  In this file, I have the code that verifies the existence of the session.employee_number. If there is no they expired or book marked a page in the application in which they need to be logged in to view:

  < cflock timeout = "30" throwontimeout = "Yes" type is 'READONLY' scope is "SESSION" >
  <! - checks to ensure that the user has a session - >
  < CFIF NOT IsDefined ("Session.employee_number") >
  "< CFLOCATION URL ="http://#cgi.HTTP_HOST#/myApp/LoginAgain.cfm">."
  < / CFIF >
  < / cflock >

  time to time (I would say on average 5 times a week) I get a message to a user error (I redirect errors to my email with information on the diagnosis). the error reads "EMPLOYEE_NUMBER element is not defined in the SESSION". when I look at the page the error came I see my call to the file check_session.cfm about 50 lines above where this error occurred when I tried to reference session.employee_number. Why wouldn't he not find it and redirect the user to the page timeout? I can't reproduce this error on my machine... I always get the good result without the error message. It's a random, sporadic, intermittent error.

  A long time ago (but in this Galaxy) we found isDefined() can give false positives with session variables, exactly the way you describe.  Or indeed something as simple as this could mistake with "session.foo does not exist" on line 2 (ie: the line inside the if() function.)

  If (isDefined ("session.foo")) {}

  something = session.foo.

  }

  And the session variable absolutely did NOT exist (or a similar variable was in none of the controls isDefined() extended, for example: variables.session.foo).  If the error was right... but the isDefined() call did not work.

  The problem was occasional, so hard to follow.

  We changed the calls to structKeyExists() and the problem disappeared.

  It was in CFMX7 well, and we had not never really much time investigating her in addition, after that we have treated the symptom.  However, I have been conscious of others with similar experiences.

  However we have stopped using isDefined() right there (for all) and has never ever had similar problems.

  Maybe try it.

• Impossible to filter a recordset using a session variable

  I have a voluntary application page, then when volunteers press < Submit > their info is stored in a MySQl db table and a session variable is created containing the primary key of the record in the table, control is passed to a page of 'success' The success page accesses the session variable (I proved this by displaying the session on the success page variable) so my next step was to create a recordset in the success with a filter page using the session variable to select the appropriate line in the table, allowing me to view the volunteer to the info They argued.

  I created a page to pass the test that displays the session variable and a field of the volunteer info. When I test this I can't see the session variable is displayed, but the corresponding volunteer info of the recordset field is not displayed.

  The volunteer application page is here www.hollisterairshow.com/volunteerapp.php and the successpage is here www.hollisterairshow.com/thanksvol.php

  The code that creates the session variable in the voluntary application page is displayed below

  $_SESSION ['volunteer_id'] = mysql_insert_id();

  The code to display the session variable in the success page is shown below

  <? PHP echo $_SESSION ['volunteer_id'];? >

  The code to display the volunteer info is shown below

  Thank you < h1 > <? PHP echo $row_rsVolunteerApp ["FirstName"];? >! < / h1 >

  The recordset definition is shown below

  

  The result of the test success page is shown below, as you can see the name of the volunteers is not displayed immediately after the "Thank you" message, but the session variable containing the correct primary key (41) is displayed correctly.

  

  Someone has an idea what I am doing wrong?

  Thank you

  Tony

  Where did you put session_start()? It should be before the variable is accessible. This is obviously before the line that displays the value in your page, but that's before the SQL query is generated?

  Also, have you checked in phpMyAdmin to see if volunteernumber 41A all values in the database?

• Strange behaviour of PHP session on IIS server

  Everything worked fine until tonight. PHP has started having a strange behavior with session variables. I use a test server for IIS.

  The session of a form is not deleted, it remains for always in the cache. Even when I restart the computer the session keeps being restored. Now, I have a forum running phpbb on the started testserver and phpbb to store the session variable in the string. I tried, but here's where I'm stuck.

  It has worked well so far and I didn't make any changes to the php.ini file.

  Here's a form part of the ini file to the session regarding:

  [Session]
  ; Manager used to store/retrieve data.
  session.save_handler = files

  ; Argument passed to save_handler.  In the case of files, this is the path
  ; where the data files are stored. Note: Windows users have to change this
  ; variable in order to use PHP's session functions.
  ;
  ; Since PHP 4.0.1 you can set the path as:
  ;
  ;     session.save_path = "N; ' / path '.
  ;
  ; where N is an integer.  Instead of storing all the session files in
  ; / path, what this will do is use subdirectories N-levels deep, and
  ; store session data in these directories.  This is useful if you
  ; or have problems with a lot of files in a directory of your operating system and is
  ; a more efficient layout for servers that handle a lot of sessions.
  ;
  ; NOTE 1: PHP will not automatically create this directory structure.
  ;         You can use the script in the directory ext/session to that end.
  ; NOTE 2: See the section on the garbage collection below if you choose to
  ;         use subdirectories for the session storage
  ;
  ; The file storage module creates files with mode 600 default.
  ; You can change this by using
  ;
  ;     session.save_path = "N; MODE; ' / path '.
  ;
  ; where the MODE is the octal representation of the mode. Note that this
  ; does not overwrite the umask of the process.
  ; session.save_path = "/ tmp".

  ; Whether to use cookies.
  data = 1

  ; session.cookie_secure =

  ; This option allows administrators to make their users invulnerable to the
  ; attacks which involve passing the ID of session in the URL; 0 by default.
  ; IDs = 1

  ; Name of the session (used as cookie name).
  session. Name = PHPSESSID

  ; Initialize the session at the start of the request.
  session.auto_start = 0

  ; Duration in seconds of cookie or, if there are 0, until the browser is restarted.
  session.cookie_lifetime = 0

  ; The path for which the cookie is valid.
  session.cookie_path = /.

  ; The domain for which the cookie is valid.
  session.cookie_domain =

  ; Whether you want to add to the cookie httpOnly flag or not, which makes it inaccessible to the browser JavaScript scripting languages, for example.
  session.cookie_httponly =

  ; Handler used to serialize data.  PHP is the standard serializer of PHP.
  session.serialize_handler = php

  ; Define the probability that the process of "garbage collection" is launched
  ; on every session initialization.
  ; The probability is calculated using gc_probability/gc_divisor,
  ; for example 1/100 means there is a 1% chance that the GC process starts
  ; at each request.

  session.gc_probability = 1
  session.gc_divisor = 1000

  ; After this number of seconds, the stored data will be considered as 'garbage' and
  ; cleaned up by the garbage collection process.
  session.gc_maxlifetime = 1440

  ; NOTE: If you use the subdirectory option to store session files
  ;       (see session.save_path above), then garbage does * not *.
  ;       be done automatically.  You need to do your own waste
  ;       collection using a shell script, input cron or any other method.
  ;       For example, the following script would be the equivalent of
  ;       definition of session.gc_maxlifetime on 1440 (1440 seconds = 24 minutes):
  ;          CD/path/to/sessions; find - cmin + 24 | XARGS rm

  ; PHP 4.2 and less have an undocumented feature/bug that allows you to
  ; to initialize a session variable in the global scope, even if register_globals
  ; is disabled.  PHP 4.3 and later you will warn, if this feature is used.
  ; You can disable the feature and warning separately. Right now,.
  ; the warning that, if bug_compat_42 is enabled.

  session.bug_compat_42 = 0
  session.bug_compat_warn = 1

  ; Check HTTP Referer to invalidate stored outside URL that contains identifiers.
  ; HTTP_REFERER must contain this substring for the session to be
  ; considered valid.
  session.referer_check =

  ; How many bytes to read from the file.
  session.entropy_length = 0

  ; Specified here to create the session id.
  is =

  ; session.entropy_length = 16

  ; is = / dev/urandom

  ; The value {nocache, private, public}, to determine aspects of HTTP caching
  ; or leave empty to avoid sending anti-mise headers cached.
  session.cache_limiter = nocache

  ; Document expires after n minutes.
  session.cache_expire = 180

  ; Note that all valid entries require a '=', although no value follows.
  url_rewriter. Tags = 'a href, area = href, frame = src, input is is src, form = fakeentry'

  Can someone tell me please in the right direction?

  Some things to check after I google a bit.

  1. in the ini files, check these settings

  session. Lifetime

  session_gc_maxlifetime

  Also are the permissions correctly on the folder containing the session files.  Perhaps incorrect permissions are disabling php to delete the files.

  Finally,.

  What version of php?  Maybe it's a bug and you need to upgrade php?

• Display a session variable in a table of shopping cart.

  I try to view a session variable generated from a connection to a shopping cart page so that I can then filter the content of the cart by user.  The cart is a table in a MYSQL/PHP database.

  I have very little experience in php/mysql, so I'm probably doing something wrong.

  1. At the present time, the user must connect before adding a product to the cart - this has been implemented in the behaviors panel.
  2. A form has been implemented on my product page so that when the user clicks on the "buy" button, the product_id, quantity of the item etc is inserted in the table of shopping cart.
  3. I tried to use the bindings panel to add also the user name which I believe has been implemented as a session variable in the login page and included in a hidden field on the form, but when I look at the table in phpMyAdmin, that the following text is displayed in my column of variabe session:
  4. < br / > < b > view < /b >: Undefined variable: _SESSION in < b > C:\wamp\ www\boutique_wines \wine.php < /b > on line < b > 114 < /b > < br / >
  5. Line 114 reads as follows: < input name = "username" type = "hidden" id = "username" value = "<?" PHP echo $_SESSION ['MM_Username'];? ">" / >

  Help, please

  Mark

  Mark,

  Basically, you are saying this: my car does not start. I want it to start, but when I put the key in all I see is a lightweight control engine. Help, please.

  It is difficult to help you if you show us what is under the hood.

  I guess that the session is not started on the page, resulting in an undefined variable error message. Also, it is not a good idea to insert a field hidden dynamics of information if you are just using the hidden field to insert information into a database. Form fields can be hacked. What is to stop someone to visit your page, copy the source of your form, changing the value of the hidden field, download the form altered on their server and submitting the form to your processing script? Bypass the hidden field method and simply insert the session username variable directly in the database via a query to avoid manipulation of the input field.

• Session variable in the WHERE clause of the SQL statement

  Hey all,.

  I was wonering just if there is a way to set the WHERE clause of the query that the session variable?  I have the following so far and have tried to go through a ton of tutorials, but it doesn't seem to work.  Is it still possible?  I don't know what follows is wrong, but can someone help me with changing the following code, or pointing me to a good tutorial?  (I write it with PHP)

  $query = "SELECT * from members where user_id = ' $_SESSION ['members']";

  Thanks for your help.

  $member = "-1";
  If (isset($_SESSION['members'])) {}
  $member = $_SESSION ['members'];

  }

  What you want to do? Given the nature of your question, it seems that you probably don't know what a session variable is used. The PHP manual describes the purpose of sessions here: http://docs.php.net/manual/en/intro.session.php.

  I need to change all the form variables in $msg in session variables. The $to part is supported. What remains are the $subject and $msg fields.

  $à = « à : ». $_SESSION ["toemail"];

  Why do you need to change the form variables in session variables? They are already stored in session variables, or they come directly from the form?

  The $to part is not supported. When you pass $to to the mail() function, it should contain only an e-mail address, not a string that begins with "to:
