Preventing HTML Form Spam?

I've been trying to research ways to solve this problem for
weeks now. Currently I have a contact form on this site with
javascript validation that only allows a user to submit a form once
the fields meet certain requirements (i.e. an actual e-mail
addresses in the e-mail form, numerals only for the phone number,
etc.) but apparently if the bot has javascript disabled they can
bypass all these safeguards and submit the form regardless.
I am not a programmer by any means, I am a Graphic Designer
with decent HTML and CSS knowledge but little other programming
knowledge. If anyone could point me in a direction that can help me
solve this problem I would really appreciate it!
Thanks.

They would still have to do some server side programming for
that... and
since they aren't a programmer they can either hunt and
install a script
from say hotscripts.com or hire someone to do it.

Do Flash Forms kill form spam?

This may be a real newby question. Is it possible to stop
100% of form spam by using a hidden field in a Flash form, and then
simply testing for is presence on the page the form posts to? Is it
really this easy?

Flash forms have a lot of disadvantages compared to html form
for both the user and the developer. If spam is your concern, look
up a concept called captcha.

Web form spam continued . . .

HI, I have tried adding a hidden field to my web form to help reduce spam. I am not sure what I tried will work and do I need to and how do I add some code to specify do not process form if this field is filled in?
Here is what I tried so far and any help would be awesome - Thanks Jim

<div style="display:none; visibility:hidden;">
     <label for="contact_email">Please leave this field blank:</label>
     <cfinput type="text" name="contact_email">
</div>
<div class="register">
            <cfinput type="submit" name="submit" value="Register">
            <cfinput type="reset" name="Reset " value="Reset Form">
</div>
               </fieldset>
</cfform>

I cannot see how anything you've said or done so far will help reduce web-form spam. Assuming you wish to prevent someone from maliciously submitting a form 10000 times to your site, then you have to use a CAPTCHA.
There is no easy, 1-2-3 way to add CAPTCHA to your application. However, some ways are easier than others. I would recommend Raymond Camden's Quick and dirty CAPTCHA Guide - for ColdFusion 8. It uses Coldfusion 8's in-built CAPTCHA functionality, and is relatively easy to adopt.

Read Only HTML Forms using adobe livecycle Output ES

Hi,
We have a requirement to display the adobe html forms in read-only format. got to know from adobe consultants that Adobe Livecycle Output ES has this feature. but i am not able to find out any services or components that would give me this functionality.
Is there a way to get these readonly forms using Adobe Livecycle Output ES.

Dear Dfoto,
Thank you so much for being so kind to spend the effort and reply back, I though my question was left behind the sun... but now I am very happy in deed.
To be more specific, the Form has 2 parts. The first part "Subform1" any one can fill and sign.
The second part "Subform2", only certain users can fill and sign.
I think I found a very strong lead to my solution, when I was playing with LiveCycle Desinger few days ago.
On the Singature Field Advanced Setting, there is a place you can attach the public part of a certificate (Digital Signature) of any user, one or more.
In this part, you tell LC that only those users "signing parties" can sign the field. I tested it and it worked.
Now, if I can use this feature via JavaScript to find out if the user who is filling the form, can sign this field, then he can fill the form. If he cannot sign the field, then he cannot fill the form. I can do that by setting the "access" property of the Subform. Another solution is that I can prevent the user from hitting the "Submit" button unless he signes the designated Signature Field.
I have another small issue:
I found out that if the Signature field is part of a repeating dynamic Subform, it will not work during run-time. Very bad in deed. While I cannot understand why ?, I tool this as "By Desing" feature.
Now, if the Signature is locking parts of forms which has dynamic content (repeating subforms), it will always show somthing like "Signature is corrupted or form was changed after it was signed".
Is this normal ? Is there a way to control Dynamic Forms using Digital Signatures without such annoying issues ?
Thank you.

Uploading an image to a servlet with out html form

Hello,
I had a look around the forum and could not find an answer to my question.
I am trying to unload an image that is in a byte array to a servlet. the image is on the mobile phone. the mobile phone does not have html form to upload the picture.
Is there any other way of uploading instead of using html form to invoke the servlet. It is just the connection bit that is confusing me. When the servlet is invoked then it can open an inputstream and take in the image.
I hope this is clear and that some one else has done it.
thanks
martin

search here and/or search google for "send byte array to servlet"
it's certainly easy to find as far as i can tell

How can an applet retrieve the values of a HTML form shown in a JEditorPane

Hi,
I'm doing an applet that contains a JTree and a JEditorPane
among other components. Each node of the JTree represents some
information that is stored in a database, and whenever a JTree
node is selected, this information is recovered and shown in
the JEditorPane with a html form. To make the html form,
the applet calls a servlet, which retrieves the information of
the node selected from the database. This information is stored
like a XML string, and using XSLT, the servlet sends the html
form to the applet, which shows it in the JEditorPane.
My problem is that I don't know how I can recover new values
that a user of the application can introduce in the input fields
of the html form. I need to recover this new values and send them
to another servlet which store the information in the database.
If someone could help me I'd be very pleased.

How can i get the value from a HTML Form

hi,
I am using HTML form (logfrm). there are userId field,password field, submit button,reset button, and a link.
when i click on the link, it should fetch the value of userid.
How it is possible?
AE

use jsp:
which lets you embed java statments in your html -so you when you click on the link you can use request.getParameter("userID") to get the userid.
Ideally with html forms use a combination of jsp and java beans, where the fields in the form are also fields in your java bean, which you can access through setters and getters.
google for some jsp tutorials.

How to retrieve input data from a HTML form in the UTF-8 cha

I encountered the following problem with a JWeb Application:
I tried to write a JWeb-Application for OAS 4.0, that retrieves
input data from a HTML form and writes it into an Oracle
database.
All processing should be done in the UTF-8 character set.
The problem is, that the form data retrieved by getURLParameter
are always encoded in a non-unicode character set and I found no
way to change this.
Can anybody tell me what I should do to get the form data in the
UTF-8 character set?

Hi
Try set in the JWEB application's Java environment such
SYSTEM_PROPERTY: file.encoding=UTF8.

Pete:
Remove the name attributes from all input elements defined by the pl/sql process. For example
<input name="company" type="Text" size="30"/> should be replaced by <input type="Text" size="30"/> or <input name="f01" type="Text" size="30"/>
The APEX accept process recognises a predefined set of HTML form input names. Any input with a name not from this set will cause the accept process to fail. f01 through f50 are valid names for the accept procedure.

How to submit a html form using java

hi friends,
i have a html form with some input fields, when ever a user submit the form the user information is stored in the database. is it possible to pass the user information in the url(url rewriting) and submit it by a java program so that the data will be stored in the database, as like as, user submit it manually.
for eg:
/*sample.html*/
<form action="store.jsp" method="post">
User Data:<input type="text" name="userdata">
<input type="submit">
</form>
in my java is it possible to store the record as below:
URL url=new URL("http://localhost:7001/webapp/store.jsp?userdata=AutomaticDatasave");
URLConnection con=url.openConnection();
int i=0;
while((i=con.getInputStream().read())!=-1)
System.out.print(i);/*it has to print the data that store.jsp is returned like information stored or error storing data(what ever)*/

hi Drclap,
Thanks for your reply, which is helpful to me....
tried what you said, what i did is modified the code like below
con.setDoOutput(true);
BufferedWriter br=new BufferedWriter(new InputStreamWriter(con.getOutputStream()));
String str="userdata=AutomateDataSave\n";
br.write(str,0,str.length());
br.flush()But
Iam Getting Internal Server Error
Exception in thread "main" java.io.IOException: Server returned HTTP response code: 500 for URL

How to retrieve data from the HTML form in the JEditorPane?

I could quite easily use JEditorPane to render and display a simple HTML file.
My HTML looks like this:
<html>
<head>
<title> simple form</title>
</head>
<body bgcolor="cccccc">
<center><h1>SURVEY THING</h1>
</center>
<form id="survey">
<p>1.Type something in.</p>
<textarea cols=25 rows=8>
</textarea>
<BR>
<p>2.Pick ONLY one.</p>
<input type="radio" name="thing" value="0" Checked> NO choice <BR>
<input type="radio" name="thing" value="1"> First choice <BR>
<input type="radio" name="thing" value="2"> Second choice
<BR>
<p>3.Pick all you like.</p>
<input type="checkbox" name="stuff" value="A"> A <BR>
<input type="checkbox" name="stuff" value="B"> B <BR>
<input type="checkbox" name="stuff" value="C"> C <BR>
<input type="submit" value="give data">
<input type="reset" value="do clensing">
</form>
</body>
</html>
It gets diplayed fine and I can type in text, select radio buttons (they behave mutualy-exclusive,
as they should) and check checkboxes.
The problem I have is with retrieving the values which were entered into the form.
If I, after editing, try to write the html to the file using HTMLWriter,
it records the changes I made into the textarea, however all the radio and checkbox selections are lost.
Maybe the problem is that when I enter the values I do not use any methods like
insertBeforeStart and so on, but I believe I shouldn't need to use them to populate a form.
Especially I never change the structure of the HTML.
Also, when I try to traverse the Element tree and see the input elements attributes,
I can never see a change in the entered values. However it is probably b/c I am traversing through
the model and the changes are in the view (just a guess.)
Anyway, if anybody could direct me onto the right path: how to retrieve the values typed in the form,
or if it is possible at all in the JEditorPane, I would greatly appreciate.
thanks

PS. I have seen the answer to a similar question posted some time last year. However, I am trying
to find a soultion which allows forms/surveys to be built by people who have no java and only basic
html knwledge. And Axualize way is probably a little bit too "high-tech."

Maybe helpful for u.

Can Java be used to save content of HTML form to a file?

We have an application that saves a pdf file to a location on our webserver. The file displays on the users machine in a browser window. I have created a link in the links bar of the browser window which launches a simple HTML page. This page allows the user to enter a number of fields and click 'SAVE'. This is where I am having the problem. I need the save button to firstly create a csv file on the webserver containing the details input by the user. I then need the pdf file saved to the web server with a new name and in the same location as the csv file. is there anyway to achieve this using Java or can anyone please point me in the right direction?
Thanks

<<Click on the SAVE button in an HTML <form> and the browser will perform an HTTP POST of the data to a URL. Make that URL point to a Java servlet and it can take that form data
<<and write it to the webserver file system in any format you wish, including csv and pdf.
agree with duffy. You can also use JSP and call a class method to handle whatever data you specify.

Is there a way to create reusable HTML Forms that can be used on multiple pages?

I'm trying to understand the recommended approach to managing 10 HTML forms that will be reused on many different pages. I want to be able to modify the form definition once and have the change propogate.

Is your requirement that authors be able to change the form definition, or should form definition be controlled by developers?
In the case of authors being able to change the form definition then I would say best practice would be to create a page that holds the form definition (using whatever components work for you - either the out of the box form components or something custom). Then use the reference component to point the definition in all the other locations you want the form to appear. One thing to note is if you are using dispatcher for caching you need to make sure you strategy for cache flushing accomadates this approach.
In the case of developers controlling the form definition you could crate a component for each form, and then simly drag that component onto the pages that require the form. In this case your would control all the form label and description elements in the localization file.

How can I change the order of html form data submitted to me via email?

I am having customers contact me via an html form posted on my website using the "sendtoemail" command. When I receive the data in an e-mail it is not presented in the order it appears on the web page and I can't seem to find out what dictates the order the data is presented in or how I can change it.
Anyone have any ideas on how I can make HTML form data elements appear in the order I want?
Thanks,
Andy

Or find a commercial form-to-email script that is compatible with your server's configuration (PHP, ASP, Perl...) and customize it to your needs.
