store session variables and retrieve the

A few months ago, I wrote a web application that uses the session to store user entries that move from one page to another. It was very successful. Then I tried to recover the data in the fromt the database field when the user connects after disconnection, but I was unssuccessful. This is my script. All I want to know who is there at - it a way to store and retrieve my session or fill my entry complete with data from the database.

I use cf9 and mysql on a window7

< cfset numberofSteps = 5 >

<! - the session.registration structure contains the user input - >

<!-who move in the wizard, make sure that there is->

< cfif not isdefined ("session.registration") >

<!-if structures are not create / initialize it->

< cfset session.registration = structNew() >

<!-start current wizard step represent one - >

< cfset session.registration.stepNum = 1 >

<!-we will collect these user; departure at one->

<!-we will collect these user; departure at one->

< cfset session.registration.firstname = "" >

< cfset session.registration.lastname = "" >

< isDefined ("form.fname") cfif >

< cfset session.registration.firstname = form.fname >

< cfset session.registration.lastname = form.lname >

< action = 'action =' index.cfm cfform? "" StepNum = #URLEncodedFormat (session.registration.stepNum) method # ' = 'post' preservedata = "yes" ' method = "post" >

< cfswitch expression = "#session.registration.stepNum #" >

< cfcase value = "1" >

< cfinput name = "Pnom" type = "text" VALUE = "" #session.registration.firstname # "onChange =" javascript:this.value=this.value.toUpperCase(); "class ="EGIT-txt"required ="true"validateat ="onSubmit"message ="You must enter a first name."/ >

< cfinput name = "lname" type = "text" VALUE = "" #session.registration.lastname # "class ="EGIT-txt"required ="true"validateat ="onSubmit"message ="You must enter a name last."onChange =" javascript:this.value=this.value.toUpperCase(); "/ >

< / cfcase >

< / cfform >

You can do it

#firstname #.

OR

#queryname.firstname #.

NOTE: in the first option if there are more then a line in the database (from inegrity of data) they will be more hten a table (since it will loop through lines in the cfoutput)

in the option sec., it will take the value of the FIRST record in the QUERY, regadless of the number of rows contained in the query.

Hope that this clear things for you...

  • Helps the guest of session variable and dashboard

    Hi, I ran into soemthing that I can't understand.

    In the administration tool, I defined a CURR_MONTH session variable and set the query to find month max in the date dimension. It's all works fine - if I test the variable in OBIEE administration tool, it currently returns "January 2010".»

    In addition, in the responses, I can create a query that moves back calendar information and then put a filter on it so the specific columns is equal to the session variable. It works perfectly - I get the 3 lines of return data that correspond to the 3 days of data we loaded for January 2010.


    However, now that I'm trying to do is set a dashboard with the dimension command prompt date in it. I want the default to months / year equal to the value of CURR_MONTH. However, when I do this, instead of getting the correct value, for some reason some, it becomes the default value I put in place for this variable.

    Any ideas on what I am doing wrong or if it is a bug?

    Thanks in advance,

  • Create Unique Session Variable based on the login page

    Hello:

    I'm building a dynamic website with Dreamweaver CS5 with Coldfusion 9.

    My question is how can I set a session variable to read a certain value. It is currently when my clients go to the login page they enter their username and password. I was able to create a session variable that contains the user name as value. So in all their pages read Welcome website "all that was their connection username. Now, I want to get the session variable to read the same table but the different FullName field.

    A session variable is also the best route to go? I'll use this to query databases to display and allow them to change contact information, also show their invoices and request services.

    I don't know CF so forgive me, but you can create a session for fullname variable or use a query on your pages to filter the data WHERE username = user session variable. Looking at your code, it looks like you can add a session to the full name variable here:

  • Session variables and presentation. Examples?

    Could someone provide me with some info and examples on how I can display the contents of the session variables and presentation?

    I read the manual, I can use @{presentation.variable} - as of the statements, but they do not seem to work. Anyone have an example?

    Thank you very much in advance

    Fabio,
    It is interesting to read the presentation services administration guide familiarize themselves with these, it is one of the best pieces of documentation.

    To reference a variable use of presentation @{VariableName}, if you write this in an expression you can set a default value using @{VariableName} {defaultvalue}

  • 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.

  • How to create impulses cause a pulse width Variable AND at the same time

    Hi all

    I have a NI PCI-6251 that comes with 2 counters, a FREQOUT port and then some DIO, DAC and ADC.  I want to trigger a pulse of variable width (easy to do with two counters) and a frequency closed, exit at the same time.  So, I want to end up with a line that will display TOP for some variable time, while the other exits a train of pulses for a time variable.  It is easy to do if you have 4 counters but I don't have one.  Does anyone have an idea to implement these two things AND making them trigger at the same time with the PCI-6251 card?

    The line is high for as long as your pulse train controlled?

    If so, set up the first counter as output pulse, configure the 2nd as output continuous meter but with the internal of the first counter output as its trigger to pause (pause when it is low).  Start the 2nd meter before the first.

    If not, you will need to use the digital output to replace at least one of the counters (max sampling rate is 10 MHz, so this would give less resolution compared to the time base of 80 MHz counters).  So you would simply write the waveform predetermined in the buffer and he clock at the desired rate and the number of samples to give the signal that you want.  You need to generate some other subsystem as FreqOut clock.

  • Session Variable Multiple of the default initializer

    Hello

    I created a session variable in the RPD to default to a guest of dashboard of Department, for a set of users, to their competent services that they are responsible.

    My question is; If the session variable returns no row, is there a way to define initialization by default to select all values in the prompt the Department dashboard? I've been successful by setting default initialization as a value unique Department.

    Thank you

    WITH tmp AS (
    select department
    from employee_department
    where sup_full_id =UPPER('User1')
    )
    select department from tmp
    union
    select department from employee_department
    where 0 = (select count(*) from tmp)
    

    Something like that is supposed to work: If you have lines to "User1", it returns a DIFFERENT one on this list, if nothing is there returns you all values (with a separate as well thanks to the UNION).

  • SQL how to use a variable and use the result as a reference for the name of the table

    Hi all

    I have new in the declaration of Oracle, sorry in advance if something is easy for you all. BTW, I have this scenario:

    I have a table OL structured in this way:

    Date - it contains dates, for example 11/01/2015

    TableName - it contains strings, for example, OL1, OL2, OL3 and so on...

    Then I have a different table, the name of these tables are of the same name in the table of the OL, so I have table table, OL1, OL2, OL3 table and so on. The structure of these tables is the same. And Yes.
