Http Session combing HTML forms and List / Menu Components

My problem is the following one... I have a .jsp page that includes a form with three List / Menu Components. I want my second List / Menu Component to be filled with data depending on the selection I have made to the first List / Menu Components. (Of course there is a MYSQL database behind). And I want the third List Menu Component to be filled with data depending on the selection I have made to the second one.

Three options:
1) use incredibly large javascript arrays to hold the data for the second and third lists and use onChange events in the first and second list to alter the list contents based on selection
2) use ajax calls to fetch the data for the second and third list, still using javascript events to listen for selections.
3) do a form submit on each selection and fill the lists server side.
The third option is of course by far the easiest, but that will give you submits in between that you may not want. Ajax is a good solution to this problem in my opinion.

Please help! How can I validate Radio Buttons and List Menu with PHP.

Hello everyone, I have been learning PHP step by step and
making little projects.
The point is I find it easy to learn by doing "practical
projects."
I have been reading the David Powers's Book on PHP Solutions
and it's really great, however there is nothing mentioned regarding
Validating Radio buttons. I know the book cannot cover every aspect
of PHP and maybe someone in here can help.
I have been learning how to process HTML forms with PHP.
The problem is every book or tutorial I have read or
encountered fall short on validation.
I'm wondering how I can learn to validate Radio Buttons and
Select List Menu.
I have managed to create validation for all other fields but
have no clue as to how I can get validation for Radio Buttons and
List Menu.
I would also like an error message echoed when the user does
not click a button or make a selection and try to submit the form.
I would appreciate any help.
Patrick

It's not that default value is "None." In fact it's not. It
will only be
"none" when the form is submitted.
Also if your submit button is names 'send' then
$_POST['send'] will only be
set if the form was submitted.
Make sure you didn't hit the refresh button on your browser
which usually
reposts the information. Also make sure you did not reach the
form from
another form with the same button names.
Otherwise paste the snippet.
Also you can check what fields are set in the post array by
adding this to
the top of (or anywhere on) your page:
print_r($_POST);

Images in HTML forms and/or reports

Hi,
Apologies if a stupid question, but can you display a combination of data and image content in Portal HTML forms and/or reports? If so, how?
This question assumes that the image in question is browser-supported (e.g. gif file), and the link to it is in the same database table as the data being reported (as a bfile data type).
Alternatively, what if the image was actually directly stored in the database table as a BLOB data type?
Help!
Cheers, Jeff

Hi Sharmila,
Thanks for the info!
Would this also work if the image wasn't a blob, but instead just stored on the filesystem (as a gif file), with the reference to it stored in the database as a bfile datatype?
Thanks once again, Jeff
Hi,
You can build portal forms to upload images. You can use blob columns here. You can also have images in a report. This will be the SQL to query data from tables having intermedia data.
Select a.empno,a.ename,a.mgr,a.sal,
portal30.wwv_user_utilities.get_intermedia('EMP','EMP_AUDIO','AUDIO',a.rowid)
the_audio, b.dname,b.loc,
portal30.wwv_user_utilities.get_intermedia('DEPT','DEPT_PICTURE','IMAGE',b.rowid) the_picture
from emp a, dept b
where a.deptno = b.deptno
The table should have the ordimage column type.
Thanks,
Sharmila

HTML Forms and Procedures

Hello!
We are trying out APEX for the first time. We would like to keep our business data objects in a different schema from the APEX schema. I have been able to successfuly create a proc and create a form over the proc in the differenet schema.
I'm wondering if we can create HTML forms and later reference the procedure. The goal is to have the Database Developers create the procs while the developers create the forms at their own pace, then later wire that form to the proc. I hope this makes sense!!
Thx!

I resolved this on my own. Pretty simple, just new at this.

HTML forms and tables w/Oracle

Hi,
New to Oracle - used AMP before.
My new organization does not use any open source so PHP is out. I assume I could use .net or java instead to DB query from HTML forms and render DB results to HTML tables.
But besides .net and java are there any other languages that work well with Oracle for this purpose?

HTML form and java

Hi,
I have been pulling my hair out for the past week on this with no suces EVEN after forum searching, googling ..........
Here is the problem:
I have an HTML form of the following type and need to pass in a Javascript variable to the servlet called on hitting the submit button.
<script>document.write('<form name="Test" method="get" onSubmit="return chkfields(this)" action="/servlet/NewServlet?ABC='+unescape(params["ABC"])+'">')</script>For debugging purposes, I have a document.write statement and I see it on the page right above that line and it does display it on the field. However this thing does not pass the varible to the servlet. I even tried replacing the unescape(params["ABC"]) with just the variable name used in the form as ABC and that did nto work either. Please suggest any other suggestions.

test.html:
<!DOCTYPE HTML PUBLIC "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<script language="JavaScript">
function setHidden() {
document.testForm.testInput.value = "test";
return true;
</script>
</head>
<body>
<form method="post" name="testForm" action="test2.jsp" onSubmit="return setHidden()">
<INPUT TYPE="hidden" NAME="testInput">
<INPUT TYPE="submit" VALUE="submit">
</form>
</body>
</html>test2.jsp:
<html>
</head>
<body>
<%
out.println(request.getParameter("testInput"));

Accordion Panels and List Menu don't work if I place html files in subfolders

Hi all,
Switched from Dreamweaver to Muse and I have very limited knowledge of code.
Not an IT expert and not a web developer this is just for my own site.
I have sub-folders in my site. All html files are inside sub-folders except index.
ie contact.html or products.html I move them manually from root to the subfolder, using the easy interface of Dreamweaver. I call the subfolder "en"
so I can have pages such as mysite.com/en/contact.html
In the subfolder I copy and paste from root the css, images and script folders,
keeping the original css/images/scripts as well, in the root, so index.html is not affected.
and same time the look of the html pages inside the subfolders does not change.
BUT
list menus and accordion panels don't work. I click and there is no movement
How can I solve this ? I know Muse does not allow the creation of subfolders,
everything is uploaded in the root.
When in Dreamweaver I had placed 50 pages in subfolders and I was indexing them in google and bing.
Now can't again put 50 pages in root and can't remove URLs and make new indexing for all these pages
Any help ? many thanks for any assistance.

Whats the difference between Info path forms and List form?

Hello,
Can any one please tell me when we have to use list or infopath form ?
Thanks,

Hi,
Use a list if:
You want to quickly get started building InfoPath forms on SharePoint
You need to use your form offline with SharePoint Workspace (formerly Groove)
You want to filter your SharePoint list based on a person or group
You would like to use the built-in display / edit views
Use a form library if:
You have repeating or nested data
You are working from a predefined industry or complex schema
Your form needs to be digitally signed
You need code in your form
Your form is not hosted in SharePoint or you need to store results as an XML document

Unable to view A/R Invoice form and Main menu

Thank you in advance.

HTML Code and Snap menu (follow-up)

Hello,
I posted yesterday and some people were nice enough to help me. I'm following up and hoping to get additional info.
I'm trying to eliminate "Brain Fitness" and "Mind Max" from my snap menu (please see "Menu Items" attachment ). I removed the code that I thought corresponded to those links - I'm posting two additional attachments. The code I removed is highlighted in red. It made no difference - absolutely nothing appears to have changed.
The website address is www.mypotentia.com. I know I am missing something, possibly something simple - if anyone wants to give me a suggestion, I will be thrilled! Thank you very much.
Alexis

Your pages are template pages and this is probably why you cannot remove the code, (this is also why certain items appear grayed out).
Find your master template page, (it will have the file extension dwt, and is probably in a folder named templates) and delete the following code there -
<p><a href="program_brain_fitness.html"><img src="images/programs_brain_fitness.gif" alt="Click here to learn about POTENTIA's Brain Fitness program" width="140" height="26"></a></p>

HTML forms and Servlets

Hi all.
This is the story:
I got a SELECT field that contains OPTIONS with values and labels (both different). How I do to get this two data.
With request.getParameter("menu1") i can get the VALUE, how i can get the Label?
Second quiestion:
I got a input checkbox type , this has a VALUE property, but In my servlet i just want to know if it's cheked or no.
If i do something like request.getParameter("check1")I get the VALUE data. how to tell if it is cheked??
Thanks in advance any help.

First Question:
The option value is what gets sent is when the form is submitted. If you want the information sent then you'll have to add it to the value and parse it out in the servlet.
Second Question:
Only checkboxes that are checked get sent when the form is submitted. If the parameter does not return null then the box was checked. If the box was not checked then the getParameter call will return null.

A JSP should not be involved in this. The browser will offer a way to specify a file, and the target of the form should be a servlet that can handle multipart uploads. JSPs should not process any input.

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.

HTML Forms in OHJ

We would like to be able to link from our online documentation to our corporate website through our secure customer portal, giving users access to features like discussion lists, FAQ, and bug fixes. In order to do this, we need to have functioning HTML Forms and SSL connections. I haven't been able to get HTML forms to work. Is there a fix coming for this? What about SSL? Is that built into the ICE browser?
Jeff Beal

Unfortunately this is an issue with Android and it isn’t possible for us to fix it. As a workaround you can either:
Display our credential dialog after the reader taps a button in your banner instead of trying to collect the username/password in the banner itself
Use a full custom store and collect the information in that
