if you mean clicking on "submit" button more than once, then
you can use
javascript to disable/hide it after it has been clicked.
i.e. <input type='submit' name='submit' value='Submit'
onclick='this.disabled="true";'>
of course, if your user has js disabled in his/her browser,
the trick
won't work...
if you want to prevent someone consciously repeatedly
submitting the
form, look into employing some sort of user
authorization/authentication
framework

Multiple Submit buttons in Adobe form !

Hello Experts,
Scenario :
Form has Material number as input field and Material description should get automatically populated( maybe as a script or button , dont know yet ). Then the form is to be submitted at the backend.
I have created an Adobe interactive form with Multiple Submit buttons( one is Submit toSAP) button , other is a normal pushbutton( for Material desc to be populated ) . I have been able to Submit data at backend.
But problem is there is only one event on the Interactive form UI element properties.
Please suggest how to achieve the above ? via script or sm code in web dynpro ?
System Config : WAS 6.4 / SP12 .
Need a quick resolution. Generous points for help.

Sonika

Hi Sonika,
control_param structure is used in case of ISR forms, but I dont think your form is related to the ISR.
Use a context attribute, and set its value to get the Material description from backend.
Like you can define an attribute in context, "GETDESCRIPTION", and set its value at the exit event of Inputfield to "GET".
$.parent.GETDESCRIPTION.rawvalue = "GET"
app.eval("event.target.SAPSubmit();");
And at the click event of the button you can write:
$.parent.GETDESCRIPTION.rawvalue = "SET"
app.eval("event.target.SAPSubmit();");
And in the backend, read the value of this attribute and perform the desired action.
Hope this helps,
Amit

How to distribute a form with multiple submit buttons?

I have a form that has multiple submit buttons depending on the information that is being entered and then who the information should go to. When I try to disbribute the form, I get an error message stating the following, "Acrobat is unable to distribute this form because it contains multiple submit buttons with different formats or return URLs." Is anyone able to let me know how I can distribute the form?

Sounds as if you need your own web script to process submissions - written by an experienced web programmer (I very strongly recommend someone familiar with all the latest security weaknesses, and not a project for anyone else). Your needs are (it seems to me) too complex for Adobe's automatic system.

Multiple submit on single form

hi all,
My current system have 1 submit button with single form. This submit button will call file_content.upload.
htp.p('function on_submit() {');
htp.p('     ...the rest of my code here..');
htp.p('     document.forms[0].submit();');
htp.p('     return true;');
htp.p('}');
htp.p('<form enctype="multipart/form-data" method="post" action="file_content.upload">');
htp.p('     ...the rest of my code here..');
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()"></form>');My question is, i want to enhance this by adding additional 1 submit button with value "Save". But this new "Save" button will call/trigger different file. This new button will call file_content.update. How to accomplish this and how to differentiate these 2 button?
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()">
          <input type="button" id="btn_Save" value="Save"></form>');Appreciate any help from you guys. Thanks

PRocessing Multiple "Submit" buttons

I want my JPS to have multiple submit buttons, one for Contineu and one for Cancel. It appears to me that the only way to detect which was clicked in the servlet is pretty inelegantly, something like this:
if(request.getParameter("continue") != null)
// do continue stuff
else
    if(request.getParameter("cancel") != null)
// do cancel stuffIs this correct? Is there a less cumbersome way? Thanks.

I will suggest that you write two servlets one to do cancel action and the other to do continue action and through JS call the servlet of cancel or continue.
that makes your work easier.
Like this
<Script language="JavaScript">
function fn_Perform_Action(chr_User_Action)
               //-- 2.1) -- ADD a record to database
               if (chr_User_Action == "Save")
                         var bln_Ret_Val = fn_Check_Mandatory_Fields();                                                       if (bln_Ret_Val)
                                   document.frm_name.action = "/path";
                                   document.frm_name.submit();
                                   return true;
               //--2.3) -- Back to the Menu
               if (chr_User_Action == "Back")
                                   document.frm_name.action = "/path";
                                   document.frm_name.submit();
                                   return true;
                    return false;
</script>
<Input Type="Button" Value=" Update " id="id_btn_Save" Name="btn_Save" OnClick="return fn_Perform_Action('Save');">
<Input Type="Button" Value="Back" id="id_btn_Back" Name="btn_Back" OnClick="return fn_Perform_Action('Back');">

To avoid multiple submit clicks

Hi all,
Need your help, in avoiding multiple submit clicks in HTMLB.
Thanks in advance.
Regards,
Gangadharayya.

Hi,
This can be done by setting the button in "Disabled" state once it is clicked. This can be done by calling a java script function on the "onClientClick" event which sets the state of the button to disabled state.
Add a similar function like this in your JSP, and do the appropriate changes, it should work fine.
function Process(){
var myID = htmlb_formid+"_getHtmlbElementId";
myFunction = window[myID];
var myButton = eval(myFunction("/* Your Button's ID */"));
myButton.setDisabled();

Multiple submissions issues

multiple submissions - how to handle issues on multiple submission by the recipients if the form is intended for single submission only per recipient

If you're using a web form, there's nothing you can do. It would be possible to configure a PDF to include hidden data with each submit that identifies a particular instance of a form, but if the user doesn't save the form they could always reopen it and submit more times, so it would basically identify the submissions from a single session. So even with a PDF you can't guarantee that you'd be able to identify multiple submissions from a single user, unless you customize the form for each user.

Multiple submit buttons in a jsp form?

I've been doing some research and found out that multiple buttons in a JSP form are possible by two ways:
- We can obtain the value of the submit button to know which one was clicked in the parameters of the request using the name of the buttons (which should be the same for all the submit buttons).
- We can change the submit destination using Javascript (Horrible solution since I want my web site to be safe to be used even if Javascript isn't active in clients browsers. I will use it of course since we can do amazing things with it but I want my website to be able to work without it also)
WHAT annoys me is the fact that the value of a submit button is also his text, so if I change the text of the submit button, I will always have to check the servlet to do the corresponding change.
Is there a third choice to be able to use multiple buttons?
Olivier Voutat

It seem rather convoluted at first but it's really good. I've not worked with JSF so I've no idea how that compares but from what I know, Craig McClanahan, who came up with Struts, worked on JSF also, so I guess it could only improve on Struts.
EDIT: Here's a search result on Google'ing his name: http://www.theserverside.com/news/thread.tss?thread_id=29068
But like I said, you don't have to use Struts ( which only uses standard JSP/ Servlets stuff anyway ), you simply use one of the ideas from it.
For example; you have a properties file, say "/WEB-INF/properties/myProps.properties" with these entries:
#USERS MODULE
users.button.save=Save User
users.button.search=Search User By Name
users.button.delete=Delete UserThis would be a key: users.button.save to the value Save User
Now, in your JSP, you use JSTL <fmt> tags:
<fmt:setBundle basename="properties.myProps"/>
//set the resource bundle you want to use
//and create buttons with the proper values
<input name="myButton" type="submit"><fmt:message key="users.button.save"/></input>
<input name="myButton" type="submit"><fmt:message key="users.button.search"/></input>This would create buttons with text "Save User" and "Search User By Name" respectively
Now, finally, in your servlet:
//create a map of the properties,
//possibly on app startup using a ServletContextListener
//and put it in the servlet context for access everywhere
HashMap myProps = (HashMap)getServletContext.getAttribute("myPropertiesMap");
String buttonClicked = request.getParameter("myButton");
if ( buttonClicked.equals((String)myProps.get("users.button.save")) )
//perform save action
else if ( buttonClicked.equals((String)myProps.get("users.button.search")) )
//perform search action
//etcYou'll obviously want to optimize this. Perhaps make a method that handles the comparison so you can have neater if conditions. But you get the idea, right?

How to prevent multiple submit (replay attack)?

Hi there, I have managed to submit the form to the server side. However, is there any way to prevent the client side from keep submitting the form? I have heard of using random number, but I don't know what javascript code to place in the web page. Can anybody help, because I am stuck in the problem for quite a long time.
Thanks,
Rocky.

Thanks,
Rocky.Well there are two ways of implementing this.
1).Javascript Solutions (and mind you never always try disabling the submit button )
[http://www.elated.com/articles/preventing-multiple-form-submits/]
[http://www.web-source.net/web_development/form_submission.htm]
2).Maintaining state of the form on server side and using a token for preventing mutiple submits.
try to go through the solutions recommended in the below articles
[http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=50&t=016689]
[http://faq.javaranch.com/java/HowToPreventMultipleFormSubmits] (In struts)
Or a more generalized solution is given in the article below

Hope that might help :)

Can I have multiple submit buttons on the same form?

Hi!
I'm creating a web page that allows the user to build a mail filter, and I would like to have to submit buttons, one to add more fields to the filter and another one to save the filter... I could insert the two buttons on the, but I don't know how to distinguish them while doing the process of the form on a jsp page. Any ideas?

You can create additional submit buttons using Javascript buttons:
<input type='button' value='Add Fields'
onClick='this.form.action="/servlet/AddFields";this.form.submit()' />
<input type='button' value='Save Filter'
onClick='this.form.action="/servlet/SaveFilter";this.form.submit()' />
The value of "onClick" is a block of Javascript, so you can all a function to validate the form before submitting, etc.

It is assumed that one submit button will function for a form..if you want more that one submit form try to build as many forms as u need and put the submit inside that
that will cure your problem
and y do you want to create so many submit buttons.. instead you can make use of select button

Multiple Submit / Applychanges - Issues

Dear All,
I am having form with 3 submit buttons.
1. Submit (create)
2. submit (Approved) -> sequence ->30
3. Submit (Rejected ) -> sequence ->40
I have created 2 processes like 'submit-app' & 'submit-rej'. I have written the conditional for 2 ,3 submit buttons. If i click 2 or 3 buttons , which is last sequence process , that value only its updating . But that is not correct.
if i click 2 submit button , status value='app' should be updated in the table.
if i click 3 submit button , status value='rej' should be updated in the table.
Please help me on this.

Hi Ayyanarkulam Dhanush.R,
Could you show me the processes that you have written for Submit (Approved) Button2 and Submit (Rejected) Button3?
Thanks,
