how do you validate a form

Anon

i have a real easy queston how do you validate that a form feald has bin filled in when you submit it

Anon

Im assuming you mean via PHP and not javascript.

Just do...

if($submitted_var){
echo "You submitted a variable!";
}else{
echo "You did not submit a variable!";
}

some people are fancier and like to use..

if(isset($submitted_var))

Umm.. well with php you can do this
if you have
example:
<form method=Post action=index.php>
<input type=text name=firstname>
<input type=text name=lastname>
<submit button thing here name=submit>
</form>

then in the php you check
<?
if ((strlen($firstname)>0)&&(strlen($lastname))>0))
{
//is valid

}
else
{//not valid

}

Like that. This information is in any php book that you can get up and in majority of the tutorials at devshed.com

the prob I have is this form is being submited to an ASP script

would I have to submit it to a PHP script first then jump to the ASP

if so how do I redirect the form

lucidfx

pssst this is a PHP forum 😉

if Request.Form.item("Submit")<>"Submit" then
firstname=Request.Form.Item("firstname")
lastname=Request.Form.Item("lastname")

if ((len(firstname)>1)and(len(lastname)>1) ) then Response.Write("is submitted")

end if

I really have no idea what your talking about now though but thats an example for you of ASP getting form values submitted and checking them. If you have no idea what i just typed then I recommend you get a book. I prefer PHP over ASP 10 fold.

Hope that helps, but it i can't give you any more help then that on the description thus far and can't write the validation for ya.

Good luck

Hi!

After validating, you may use the GET method, for instance:

header("Location:www.server.com/index.asp?name=John&......");

Hope this helps,
