Validation forms

Hi, i started to work with Sap netweaver visual composer. i have to validate a "input field" where it only have to accept letters like 'Abraham cuahutle' but not 'Abraham00939383%6$ Cu398403' somebody can help me.

Abraham,
There is no such a method to check the availability of numbers and special characters in input field. You can make it as possible by checking for individual numbers and also for special characters.
Use the step I've given for numbers also for the special characters.
For example,
Condition='Contains'  Value = '%'  Msg='No special characters'
Condition='Contains'  Value = '@'  Msg='No special characters'

  • Spry Validation form objects

    I have just been looking at the Spry validation form objects
    like the textfileds and the checkboxes etc, and I like what I see,
    but I wandered how I might deal with them once filled in and the
    form is submitted.
    Currently, I create forms manually and then use the Yaromat
    Validate form which I think is really good. I create asp pages, so
    I programme my email forms to be submitted by CDONTS. Once the form
    is submitted it is then sent to a thank you page where the CDONTS
    code is sitting, and is formatted into an email and sent to the
    relevant email addresses.
    If I chose to use Spry validation instead of the Yaromat
    Check form, do I just carry on creating the CDONTS code on the
    thank you page as I would do normally in order for the email to be
    sent?
    Thanks
    Mat

    You can specify addional error locations. See this example: http://labs.adobe.com/technologies/spry/samples/validationwidgets/Single_error_message_onS ubmit.html

    Please check in KON* series table in SE16N transaction. I guess KOHN table may help you out. You can see other similar tables.
    In any one of the table you will find validity data.

  • How does Validated Form tag insert the error message?

    I'm using validated forms tags in my jsp and when there is an error in the form
    the error message is set to display on top of the wrong field. This is an attribute
    that I set in the <portlet:validatedForm> tag called "messageAlign", but I want
    to know how this is inserted or what I can do to line it up above the text field
    because it is moving all the elemnts around in the table cell. Any insight would
    be helpful.
    Thanks,
    Travis

    Hard to know what the cause is  because it's like this
    I know what I did to cause this. I upgraded my one of my hard drives, renamed the drive and moved the folder. The missing pictures it can't find were added with the option in the advance menu "copy photo to library" turned off.
    and this
    What I did is added a small SSD as my primary drive. Put the OS and all the apps on it.  Moved my iPhoto and iTunes libraries to an large external.  Most of the picture it is not having a problem wth.  Only certain ones.  Don't actually think I unchecked tha prefeence, but it's acting like i have.  
    seem to be written by two different people.

  • Partial validation form

    Hi guys! In my project i need to submit a whole form but validate only part of it. I`m planning to develop partial validation form, custom button for the form, and validation zone (envelopes the components that will be validated). I`ll use the following example:
    http://forum.java.sun.com/thread.jspa?forumID=427&threadID=643655
    Any suggestions/discussions are welcome.

    As it signalled the page of Youtube, expected this answer, but like my knowledge in this matter is scarce, had to ensure me that the problem was not the browser or the absence of a package.

    Hi,
    Here is a suggestion, if you are on ECC 6, the form HR_IN_TAXF16NX_P and HR_IN_TAXF16000Y are not delivered. You need to copy it from client 000. Check if these forms are present in your client.
    I had the same problem with ECC 6, when the forms were copied from 000, the error was rectified.
    Hope it helps.

  • Validating Form Fields

    Hi All,
    I am using Flash 8;ActionScript 2.0.
    I have a form with serveral input fields. I want to validate
    these fields. For example make sure the email input is in the
    correct format, that the telephone input has only numbers, etc.
    All of the tutorials I have looked at attach the AS to the
    submit button. I do not want to do this. What I'd like to set up is
    have AS check the input field entry to make sure it's correct PRIOR
    to the submission of the form.
    Is this possible?
    This is the AS for the form with no validation:
    tl = this;

    nameTF.tabIndex = 1
    emailTF.tabIndex = 2

    Your help is much appreciated,
    Scott

    I don't have a solution for you. The reason that the existing
    solutions that you've found use the submit event is quite simple.
    It's the least intrusive place to check for errors. You have a
    limited number of events where you can place this content checking
    code. If you wanted to test the email address that the user entered
    after that entry was made, how would you do that? You can tell when
    the user gives focus to the textfield, you can tell when the user
    enters a character, you can tell when the textfield loses focus.
    None of these events is really appropriate for testing the content.
    What is the problem with waiting until the submit button is
    used?

  • Validation Form - User Availability

    I am doing a user registration UI for a web project. Our
    database has usernames unique. I dont want the user to create an
    account, submit form, then come back and see they have an error:
    username is already taken. I would like to put a button next to the
    username input field called Check. This button i want it to check
    the username availability. I have a php function that returns true
    or false depending on the username check. I want this to be a
    validation widget to my input field. Can this be done using spry
    1.6? If, yes could you point out some hints?

    Hi,
    you can achieve this behavior by using Spry sending the
    username when the Check button is pressed and receiving as response
    the xml with the existent usernames. Your custom function will
    submit the form via XHR. The callback function will interpret the
    response from the server.
    You can see an example on this
    page.
    Also you should consider a security issue if you return the
    xml containing the usernames, because it will be available for all
    Diana

  • Include type scripts for validating forms

    hello,
    I'm new to AIF, but to internet development. here is my question.
    I have a template of a form that our HR department use in 94 different variations.
    I will use the AIF with the form and data merging to be presented to the end-user. they will have the ability to fill online or download with fill option.
    My concern is the client side validation for each form variation. Is there a way to include a client side script file to eliminate an unique form for each variation or having the specific script in each form.

    my guess- the recipient email address is using spam assassin
    or a similar
    filter. It's seeing the default first line of the email and
    giving it two
    points on it's rating system thinking it's the old matt
    wright formmail 1.6
    script.
    the fix- if it's a script you installed and can touch and
    modify, is to edit
    the script so it's got a different first line in the body of
    the email.
    If it's a host installed system wide script you can't touch-
    install your
    own like nms-formmail or phpformmail (and edit the first line
    of the
    outgoing email's body text)
    This is the line to search for in the script:
    Below is the result of your feedback form. It was submitted
    by
    change it to something else. Watch out for any characters you
    might need to
    escape in that scripting language like ' when making the
    edit.
    further sluthing- ask the client to send you the full source
    of the incoming
    email, or the email that's been sent to their spam box so you
    can see the
    email headers. Spam Assassin put it's scores in the header
    and you can see
    why it's been trashed.

  • Related to struts validation form

    Hi all,
    When entering validations on a form in validation.xml, If you have a
    fieldA with "depends=required,maxlength" and FieldB with "depends=required,email".
    If when i give fieldA with 40characters but its permitted length is 20 and FieldB is empty. Now when i click submit button it shows the error only for fieldB.
    When i give a correct email id in fieldB then FieldA error for max length is triggered..
    Is there a way for both to appear at the same time when the
    Submit button is first clicked?

    You may have more luck if you ask this in a forum devoted to Struts. There's one at their own homepage over there at apache.org.

  • Validating form by function

    Hi,
    i try to validate my form (items in them) with functions wich returns 1 or 0.
    Here is one of the function:
    create or replace
    function firmennamecheck(        p_firmenname IN VARCHAR2
    ) return NUMBER
    as
    l_firmenname VARCHAR2(255);
    BEGIN
    l_firmenname := p_firmenname;
    IF regexp_like(l_firmenname, '^[[:alnum:][:space:]]{2,80}$') OR l_firmenname IS NULL THEN
      RETURN 1;                                                                      
    ELSE
      RETURN 0;
    END IF;
    end firmennamecheck; My problem is the whitespace. If I give an input of one whitespace in the text field, they returns 0 (this is ok!),
    but if I insert more then one whitespaces in the text field, they also say, its ok!
    Example:
    ' ' = no error message. (a big problem for mandatory items!)
    'XYZ Inc' = no error message (how I want it!)
    If I Use this expression:^[[:alnum:]]{2,80}$ then it's not more possible to insert text like 'XYZ Inc', because there is a whitespace.

    Hi David,
    so this is a form where user can register on my website. In this case it is a "dealer". They give information about comanpy name, first name, last name.....
    And I want to validate this form.
    Company name is "Name Ihrer Firma" and could contain numbers and letters.
    In this case I use this Exp. '^[[:alnum:][:space:]]{2,80}$'.
    Now its possible to type in letters and numbers also whitespace characters.
    But the problem are the whitespace characters!
    The user can type in a company name like " ". Just full of whitespaces! and the validation says "its okay!" and submit the page and the data gets inserted in the user table.
    Result Example:
    select * from user: shows me the user with a company name full of whitespace charactes!
    Requirements:
    1. Numbers, Letters and Whitespace charecters are allowed
    2. Whitespaces not at the begin of the textfield
    3. Only typing whitespaces without letters are not allowed!
    David Gale I try your code, but its not working on the first time :-/
    I think You forgot some [] more.
    The finish reg. '^[[:alnum:]]{4,40}([[:space:][:alnum:]]{1,40})*$'But somethink works not fine. maximal 40 characters are allowed. I test it and type more then 40 characters in, sumbit it and without an error messages. :-/ this means, that the reg. is not 100% right! but whats wrong in the code?

  • Validation form code?

    ok. So I have these boxes-
    First Name
    Last Name
    E-Mail
    Username
    Password
    Re-Type Password
    I also have a register button.
    I have properly linked my javascript and checked for any
    mistakes but when I click the register button, I get an error
    saying that I am missing parts of my form where I want an alert box
    to come up instead.
    Attached is my Javascript.

    What does the error message say, exactly. And can we see the
    HTML?
    By the way,
    > errorMessage += "Please enter less letters.\n";
    wouldn't you want to say "Please enter fewer letters.\n"?
    > errorMessage += "Please choose select a button.\n";
    I have no idea what this says....
