Need help: understanding of the Session Variables

• 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().

• How to filter the Recordsets using the session variable?  Please help this makes me crazy...!

  I'm having the same problem as user "Gabe the facilitator" in a message sent in 2007.

• Help with the Session Variables

  It has been a long time since I used CF, probably 5 years. I remember a lot, but it seems that I forgot something.

  I have a form that accepts user data. These data are posted and another form appears. Before the CFQUERY in the in the post, I set a session variable, just before the cflocation which brings the following form.

  If I take the scflocation, I can exit the session variable.

  But when the 2nd form appears, the same session variable is not set.

  Any suggestions?

  Thank you.

  I could do this instead:

• How to check the Session Variables using the analytical web dashboard

  This is my first post. Easy points to the first right answer... If I can figure out how to give points.
  
  Problem: I need to know how to check that the Session Variables with the Administration of Oracle BI tool are used by the web analytics tool.
  
  Environment: Windows running Oracle 10g BI. Connect to the database using web analytics http:// < server >: 9704/analytics, web analytics is running in a windows Explorer browser.
  
  Current situation: the analytical tool is connected to the database and I can use the screen of "Answers" to the table edge to probe the tables look and things as expected.
  In the administration Oracle BI tool I can see the session of web analytics and I see that he thinks that the Session Variables are set correctly.
  I have reasons to doubt that the analytical tool is to get the right variables and I need to check it out.
  I know that I should use the 'Answer' window to create a shape any of a query that includes NQ_SESSION. < my variable >, but I can't understand what the format should be doing the work.
  
  That's all I need.

  What I do is insert a text in my dashboard object and then set the properties of the text object to display the variable.

  for example to display the DISPLAYNAME variable, the text object properties are:

  User: @{biServer.variables ['NQ_SESSION.]} {[DISPLAYNAME']}

  Dashboard invites on Month Name but the report on the ID of the month filter:
  Re: Guest dashboard on the name of the month but the report on the necessary month ID filter

  If you have dashboard guest (name), then you can have that one report that is filtered by a name but present card to display or not id but use id in the service. Or two reports as in the solution in the second link above and the second report has id in the function and filter by the id of the first report. You need not define this ID in the session for this example variable.

• I need help to Flash the bios. I have an Aspire 5810TZ. I start and it just says: "acer".

  I need help to Flash the bios. I have an Aspire 5810TZ. I start and he just says "acer" and goes no further. I went to the download page for BIOS on us.acer.com and it has a zip file with 5 files:
  JM4151135.exe
  IN FLORIDA...
  GPC_V135.bin
  Readme.txt
  FLASH. BAT
  What should I do? I tried to copy the files on a USB key and turn on/off with Fn + ESC key. After the release the power button and pressed Fn - Esc another screen appears after 30 seconds. I gave up and gave her 30 minutes but it does nothing. I read another person that should be flashing power button online. I have to rename one of the files. Help, please!

  Aspire 5810TZ menu of frozen startup.

  I finally understand it.

  I couldn't start a back b/c drive, it me did not start anything.

  I followed this chain of logic:

  -Downloaded the bios (2.35 is the one that worked for me)
  -Find the exe file in the winflash file.
  -Extract the files in archive exe using the 7-Zip program
  -Find the .fd file and rename it to JM41X64. FD (I read in a forum was unique in my laptop)
  -Copied JM41X64. FD and FLASH it is. EXE on a USB
  -A the battery and the hard drive out.
  -With its trendy diet I supported Fn + Esc and that you press the power button once while ensuring that the Fn + Esc has been always held down.
  -J' waited 6 seconds and release the Fn + Esc and seen the flashing flash player
  -After about 10 minutes, restarted the machine and the bios as like new.

  Later, I found that there was a hard drive problem.

  I want you guys should help more. All I needed was the name of the JM41X64 file. FD and you don't know how many hours I put into trying to find how simpy bios flash. It is not that difficult for someone with a b.s. in computer science to learn how. Couldn't we a m.s. back b/c the bios drive was messed up. F12 didn't work.

• Need help to identify the type of object in the loop of pl/sql

  Hello

  I need help to identify the Type of object declared beneath a procedure as shown below:

  I need to pass the parameter to the procedure as a TYPE of OBJECT and also refer to variables of Type Object in a loop

  create or replace type TEST_VALIDATION_REC is RECORD (order_num varchar2 (30),)

  number of inventory_item_id

  reserved_YN varchar2 (1).

  error_flag varchar2 (1).

  Error_message varchar2 (2000)

  );

  CREATE OR REPLACE TYPE VALD_TBL AS VARRAY (10000) OF TEST_VALIDATION_REC;

  PROCEDURE ADD_TO_ORD)

  p_lot_number_list IN VALD_TBL,

  p_ord_number IN Varchar2,

  p_user_id in NUMBER: = fnd_profile.value ('USER_ID'),-change 1.10

  p_responsibility_id in NUMBERS: = fnd_profile.value ('RESP_ID'),-change 1.10

  p_application_id IN VARCHAR2: = 'PO',-change 1.10

  x_error_flag OUT Varchar2,

  x_error_msg OUT Varchar2

  )

  In the above procedure, I had the VALD_TBL. Is it OK?

  And how in the loop if the records if I use:

  FOR indx1 IN 1.p_lot_number_list. COUNTY

  LOOP

  BEGIN

  SELECT

  inventory_item_id

  IN

  ln_item_id

  Of

  dummy_lot_tab

  WHERE

  lot_number = p_lot_number_list (indx1); - > how direct the item here?

  EXCEPTION

  WHILE OTHERS THEN

  ln_item_id: = NULL;

  END;

  Records are PL/SQL objects.  They are not the SQL objects.  You can create a SQL TYPE (schema level) as a collection (variable-tables only, tables nested).

  So therefore your first statement is syntactically incorrect

  CREATE OR REPLACE TYPE TEST_VALIDATION_REC IS RECORD
  (order_num VARCHAR2(30),
  inventory_item_id NUMBER,
  reserved_YN VARCHAR2(1),
  error_flag VARCHAR2(1),
  Error_message VARCHAR2(2000)
  );
  

  You must put in an anonymous PL/SQL block or the stored procedure

  DECLARE
  
     TYPE test_validation_rec IS RECORD
     (
      order_num VARCHAR2(30),
      inventory_item_id NUMBER,
      reserved_YN VARCHAR2(1),
      error_flag VARCHAR2(1),
      error_message VARCHAR2(2000)
     );
  
     TYPE vald_tbl iS VARRAY(10000) OF test_validation_rec;
  
     lv_tbl vald_tbl;
  
  BEGIN
  
     lv_tbl := vald_tbl();
    -- insert your code here 
  
  END;
  

• Cannot get the value of the session variable (using row wise initialization).

  Hi all

  I have a scenario where I'm trying to get the value of the variable session of two columns.

  Table of database consists of the name of USER, Country_Region, columns Country_SubRegion.

  For example: ChadraKanth, Americas, America West is the data.

  I wrote a Sql query in the block of session initialization:

  Select "CR", Country_Region, Country_SubRegion

  of row_wise_init

  where USERID = ": the USER"

  When I test the RPD code gives the result like this:

  CR WesternAmerica of Americas.

  In my report I have two columns, a region and an another subregion.

  When I try to filter with the session variable "CR" for the column region his error giving: session variable is not initialized with

  This is the default.

  Question:

  1. session variable is contains several values in the column?

  2. how to filter the report on columns of region and sub region?

  Please suggest me.

  Kind regards

  Chandra Khalil.

  Hello

  A session variable cannot store more than one column, 1 variable = 1 value (column 1), horizontal initialization allows to store several lines, multiple values in the same variable.

  If to a user, you have several lines with multiple values, you need horizontal initialization, but it cannot store in the variable the value of the region and subregion.

  You do not have access on the interfaces between itself or this info is not visible in vCenter? Probably, you should talk to one who is in charge of your nexus dvSwitch.

  I don't know how it works on the nexus 1000v switch, but the output of the net-dvs provides information on balancing policy for all ports (note that he understands the uplink ports that may still occur as "port id of virtual source"):

  # net-dvs. "grep EI ' (Balancing | port)"

  port 320:

  source port = load balancing virtual id

  port 321:

  source port = load balancing virtual id

  port 177:

  source port = load balancing virtual id

  You should also be able to enter this info from esxcli, but I don't know if there is a hook to esxcli for the link. Perhaps, you can branch off with cisco of dvs esxcli vswitch network or something. On the dVS of vmware, you could do:

  # esxcli dvs lacp vmware vswitch network status

  Can someone help me please. I'm new and I have no experience with the available filters.

  The session variable, NQ_SESSION. has no definition of value. (HY000)

  
  

  This means that your init block does not work. Check the init block why its not leading is not to any data.

  only when the init block fails in the data, the server checks for the default value of the variable.

  Since there is no default value, you get this error.

  
  

  Init blocks can fail because

  1 connection pool does not work.

  2. the table or view does not exist

  3. no data in the table

  4. the filter in the sql in init block is not initialized if his coming of another variable of session.

  
  

  in general, no data should bring no results in a report.

  Since you have a session variable as part of the report, and this variable initialization failed, you get this error.
  

• Value of the session Variable does not get updates.

  Hello
  I have a Session variable, I am assigning it an initial value [3] during the loading of the page. But, during the drop value menu selection and the "submit" button hit, I update the value of the Session variable.
  The update is unsuccessful and the session variable is preserved the initial value. Here's the code used to assign the value to the Session variable:
  
  < ISdefined ("FORM.submit") cfif >
  < cfset Session.numTasksDisplayed EQ #FORM.filter # >
  < cfelse >
  < cfset Session.numTasksDisplayed EQ 3 >
  < / cfif >
  
  When to use cfoutput after these instruction to check the value of the Session variable, its gives me the initial value of 3. Form.Filter is the value from the drop-down list menu option selected.
  #FORM.filter # #Session.numTasksDisplayed # < cfoutput > < / cfoutput > < cfabort >
  
  Any help is appreciated.
  Thank you and best regards,
  Vijayvijay77.

  First of all, you cannot use EQ with CFSET comparison operator. It should result in an error. If this is done on the bottom, there will be an error and nothing is set.

  Also, are you sure that FORM. Offer exists during the validation of the form?
