Hidden Form Fields

i wrote a script in asp/vb script that validates form fields. all works fine, apart from the fact that alerts are being shown against the empty form fields when the page loads the first time.

so, validation should not be carried out when the page loads the first time. my friend challenged me and said i can achieve this "using a hidden form field or even the submit button" and submitting the page to itself

i was more thinking of using session variables or a session cookie, but does anyone know how you could accomplish this using a hidden form field?

Using Hidden Fields

how can i set the value of a hidden field at run time in my page? how can it be done in scriplets (<%%>). the second issue is that if we define a function using javascript, how can it be called at any place.

we don't want to call that function at any event but instead want to call that function every time or on validating an if condition.

Using Sessions Within Hidden Fields

I have a product ordering process that passes information between 3 asp pages using web forms.

I am attempting to set a session on form2.asp with data entered into form1.asp . This session is then displayed.
I then wish to use this session value within a hidden field on form3.asp as follows

<input type="hidden" name="productname" value="<% Session ("productname") %>" >

This hidden field value is not being parsed in formmail.pl - any suggestions why this will not work?

Hidden Fields Are Visible

I have a form in which if i check one checkbox it makes 2 textboxes invisible. Thats working fine.( I am using java script to perform this)Now when user fill the form and hit submit and if some required field is missing than it forces the user to go back to form and complete it.
While going back it retains all the values for all the fields.It also retails the checkboxs but even though the checkbox is checked now but textboxes which should be hidden are visible.

Update Hidden Fields

document.forms[0].Update.value='yes';
document.myForm.submit;

in a routine.

I have declared a Hidden field called Update in my form. I have checked before the submit that the value does actually get set, but after Submission the value of Update is empty. I have checked everywhere and this is the only place in the page that this value is set.

Does anybody have any idea why my value is being lost on submit. My form is declared :
<FORM NAME="myForm" action="AgentDetail.asp" method="post">

Count Of Particular Hidden Fields

is there any Request object's method that could calculate the count of particular hidden fields, the ones that have a 'item' in their name:

<input type="hidden" name="item1" value="10">
<input type="hidden" name="item3" value="20">
<input type="hidden" name="item5" value="30">
<input type="hidden" name="somethingelse" value="40">

The result should be 3, not 4 (only the fields which names - or IDs - start with an 'item'). Note: I'm not satisfied with the solution of naming the fields with same name "item" and then split the array to get their values and read the ubound of array. I would like to keep the names of the fields as I stated in the example.

Passing Variables In Hidden Fields

I am passing variables in hidden form fields and have got it working fine. However, if the variable value has a space in it then Request.Form("fieldname") only returns the first part of the variable upto the space and the remainder is lost.

I can pass such variables in the URL using URLEncode (and a URLDecode function) but this particular form is posting to the same page. Do I have to do some kind of encoding again to format the space properly and then decode it again?

Passing Hidden Fields Into Multiple Forms

I'm having trouble passing hidden fields between forms. I have a total of four forms. I have the 1st form passing its field to the 2nd form, and the 2nd form passing its field to the 3rd form, but the 1st form's field then is not passed into the 3rd form. So obviously, my summary form (the 4th form) is not getting the 1st form's field or the 2nd form's field, only the 3rd form's field. Code:

Passing Data To Pages Using Hidden Fields

I am creating a form that has 5 steps/pages. Each page contains about 20 fields. But I don't want to write them until they submit on the last page. I figured out that I can use hidden fields to carry the data from the previous forms forward. If should bascially work like this:

Page 1 Page 2 Page 3 Page 4 Page 5 Page 6
20 Fields 20 Fields 20 Fields 20 Fields 20 Fields 100 Hidden
20 Hidden 40 Hidden 60 Hidden 80 Hidden Write to DB

But the problem I am having is when I submit page 4 page 5 won't load. No error, it just won'tload. It seems to be overburdened. Is there a max on the number of fields it can pass? Is there a better way to go about doing this that someone can suggest? Or a suggestion that someone can make to fix this problem?

Hidden Form Action

Is there a way with ASP or Java to hide the form action part of a form? I have someone that has found the location of a script by looking at the source of one of my forms.

They run some type of script that trys to post bogus info from 6:00 in the morning till 12:00 in the afternoon. Although it gets denied due to wrong input by the user, it sends administrative emails that are annoying (hundreds). If the user only saw the client side (below), they could not do it. Is there a way? Code:

<INPUT TYPE="HIDDEN" NAME="VARIABLE3" VALUE="D8F1A38F99B9320B">

The code I have looks like this. I need help getting started on how to search thru the retrieved web page to get the above values.

Pass Hidden Form Field Value To Another Form Field To Insert In Db

I am trying to pass a hidden field value on a form into another field on the
form so that it can then be inserted in the database, to enable me then to
reference that number at a later date.

other input field.)

The code for the text field that allows users to type an number into it for
submission to the db is below, but what code do i need within the hidden
field to populate this text field below so that users do not have to type the
number in? Code:

Form Fields

I have an asp page which has a number of form fields on it (about 50). 2/3rds of these fields are used to store username (windows username) and date (todays date). I want these fields to be locked so the user cannot enter any info into them. The infor will be grabbed from the current user and the current date.

However, I only want these fields to be populated only when the left most field is changed. Once the fields have been populated the username and date fields will change with however is logged in and the new date.

Form Fields To 1 Variable

I need to loop through all submitted form fields and place them all into 1 variable but i have no idea how. Here's what I have so far:

for each item in request.form

myVariable = "formfieldname:" & item & "formfieldvalue:" & request(item)

next
response.write(myVariable)
The problem with that is that response.write(myVariable) only prints the last field in the form.

I know that if I move the response.write(myVariable) INSIDE of the loop it will print correctly but I am not trying to print the form fields BUT I AM TRYING to store them in ONE variable.

For example:

myVariable = formfield1name:formfield1value:formfield2name:formfield2value:formfield3name:f ormfield3value:ETC ETC

How To Send All Fields Of A Form Without Specifying Each One

how can I send the whole form using the script below, without listing every NAME of the form. Basically I wondered if you can just put a certain code in that will send all the fields of the form without putting each NAME of the fields down indiv individualy??

My forms Name is 'conf', so I was wondering if there was a code like SENDWHOLEFORM="conf", (I know it obviously won't be that, but just to put the point across!)

<%
DIM strNAME, Mailer
strFirstName = Upload.Form("NAME")

Set JMail = Server.CreateObject("JMail.SMTPMail")

JMail.ServerAddress = "10.2.3.2"
JMail.AddRecipient "me@me.com"
JMail.Sender = "me@me.com"
JMail.Subject = "Submitted Item to sell"
JMail.Body = "Name: " & strNAME

JMail.Execute
Set JMail= Nothing
