I just spent days on a clients website incorporating Server side validation where before I only relied on client side javascript. I was getting hit with injection attacks or so I believe.
What is happening now is that on one particular form is getting submitted completely blank when in fact it shouldn't be. Code:
I have created a new site, using asp.net c#. My pages contain client side validation to validate the users input. On my local machine this works fine, but when I moved my site to the test server, the validation don't want to execute. If I view source on the page I can see the java script is created, but it don't execute.
I'm browsing to the site in IE, so it is not a browser problem and the validtation works on other sites on the same server.
I am doing login page . (login.asp)As usual it has username , password textbox and a login button .i need to do client side validation for mandatory fields and I need to do server side validations to check for the hardcoded username and password .if it matches i have to redirect to another page(content.asp)

I am using javascript and server side validation. This is a scenario for if someone has javascript turned off and the server side validation comes into play.
I have a form which submits to a hidden page which retrieves the data and the submits it to a db. When the data is posted, I am doing server validation checks before submitting to the db ie.
if str = "" or str = "" then
print this page saying 'please complete all fields'.
Now the user has to user their back browser button to get back to the form. The problem is that sometimes the values they entered into the form are there and sometimes they aren't. How can I ensure that the values they entered are still in the form?
When the moderator jmurrayhead reviewed my website he pointed me a good point that I never though would be a problem but could be. He said that turning off the browser's javascript my sign in form or other form that uses javascript won't work the way they should.
He advised to ensure I validate everything server-side instead. My queastion is how can I validate an email address on the server-side? Do I have to uses javascript too?
This would be the longest project I have worked on, but I'm trying to use client side validation on a form that collects a users information. The problem I have is how do you validate a field when processing the form and if a field say is EMPTY, then error message and the users needs to enter some data.
I know that I can say POST="validate.asp" or something, however I have this page going from one form page to another and I can't get my head around being able to validate the field on the page before processing the form and moving to page 2 form, and so on.
Is there away to have the validation on the first page and somehow once validated move to page 2 form?
Should i to validate all the "Request"s calls
like Request.FORM("...") and Request.Cookies("...")
if it is so, i have to see inside
every "Input" elements like "Text" and even "Hidden"
and every Request.Cookies i'm using ???
Can someone please explain to me what server side validation is and how this works, also where do you put this, and in which programming language do you write this. Some examples are also welkom.I've never used this but I want to learn how.
View Replies View RelatedEverytime i submit, it does no validation checks and just submits the form as normal and i cannot work out why. Does someone know where i am going wrong.

I'd like to see if there is any guidance in the form of sample code or a
tutorial for server-side validation. Specifically for the thing I am trying
to do, if a user types too many letters into Textarea, then they see an
error on the screen. I was able to catch most occurrences of this error with
client-side javascript.
However, I'd like to handle it server-side in order
to catch those cases that get by the javascript for whatever reason. If I
could just catch the error before it gets displayed, then display a warning
in red letters in a pretty format, then that's all I'm hoping to do.
I went to ASPFAQ.com, didn't find anything there. I also did a search of
this forum and didn't see anything. I know conceptually what I want to do,
but I am not sure how to go about it.
is it possible to do the data validation using ASP (server side) or javascript is the only way to do?
View Replies View RelatedTHe form is set up using a form validation script on the server and using erver.transfer to return the user to the form if it required fields are not filled in. THe issue he is having is that if he misses in so much as ONE field and submits it returns him to an empty form. I have had others try this and it works great. I'm baffled.

View Replies View RelatedI wrote a sever side form valiation script that loops through the form elements building a string in the process. If you submit the form without filling in any fields you will get the error message in read at form's top. Look how the fields in the error message are completely out of order. Why is this? Code:

View Replies View RelatedI have two .aspx web pages. The first one has a form with ASP textboxes, validation controls, an a submit button which calls an event handler using VB to insert data into an Access database then redirect to the second page.
Both pages work fine on my local host computer (IIS). But on my remote host, when I click the submit button, it just sits there and does nothing. When I remove the validation controls, the event handler works fine.
How can I get the validation controls to work on the remote server?

I've noticed a problem with calls to server.execute on a webserver running IIS 5.0. The call is used to conditionally include some asp code according to the language,but there seem to exist some memory leak due to the server.execute, because the "private bytes" for the processes, logged with performance monitor, go always up until I got "out of memory" accessing the homepage.
The memory comes back to normal with a click on the "unload" for the application but starts climbing again. Replacing the server.execute with a <!--include...--> solves the problem for me but I can't figure why this memory problem occurs.
Whenever i try to accecc HTML page through server.execute, i got this error.
Server object error 'ASP 0228 : 80004005'
Server.Execute Error
server.execute("/folder1/htmls/" & strfilename & "_1.html")
The call to Server.Execute failed while loading the page.

How do I go about calling a server-side vbscript within a client-side
javascript function? What I have is a page heavy on the javascript that has
a number of functions, one of which is to begin a visual countdown with an
onclick and also open an asp page containing the server-side vbscript, which
initiates a wake-on-lan call. I had no idea how to call the vbscript within
the javascript function, so this is why I opted for the vbscript asp page
"pop-up" via window.open. Code:

I am starting to build quite a few pages that will have
tables of data from an SQL database.
I have been building the table rows on the server side
in VBScript, but I have been thinking about having the
VBScript code just build array variables in the <head>
section (or as local variables), and then have JavaScript
functions on the client side actually populate the tables
when the page loads.
I do plan to do other things like being able to sort the
tables in JavaScript code on the client, limit the tables
height and be able to scroll the rows, and click on a row
in the table, and have the values populate a form. I will
also need to be able to export/download/? some tables into
Excel.
I wanted to just use standard INPUT buttons and colourise them, but user's
of my web app want to continue creating their own buttons and using these in
css. Before I used straightforward images, but creating an image for each
button was a mare. You see this is all to do with giving people the ability
to change the look of the web app, in other words a skin, using nothing more
than pics and css files.
My theory was that I create a div, span or whatever for the left hand side
of the button and ref the image (in css) to be a 2px wide img that can have
the curved left hand edge of the button.
I would then put a div, span or whatever next to this and the reference
image would be a really long image (horizontally speaking) so that if the
button text was long then this would keep moving to the right and
accommodate basically any text length. Code:
