I am working on a html form for work, I need to make the Subject of the email which the form produces to be unique each time.
The subject is currently hard coded in, in the format of:<form method="post" action="mailto: an.address@work .co.uk?subject= EnrolReq"
I would like the subject to include a number at the end which will increase by 1 each time, so the subject will be completely unique each time. I'm guessing it would have to refer to an external file which would keep a track of the last number used, but as for how... I'm completely stuck... over to the experts!!

that has nothing to do with css, but server-side scripting is what u need.
heres how to read and write a text file using php.
good luck
Fantasitc, thanks. Sorry the post is i the wrong area, but I'm learning....
Only thing is, when it views the extrenal text file, how can I get it to increment the number by one each time??
If you tell me where is best to post this question too that'd be great...
Thanks again...
Hey bud,
Came across your post by accident and I actually know the answer to this one:
[PHP]anyVariable= 500;
anyVariable++;
echo anyVariable;[/PHP]
The "++" at the end of the variable is the key. It is called "incrementi ng" a variable. You'll still have a little more research to do, but once you get a little more code together you should post it on the PHP forums.

Thanks for the response, but I cant figure out the answer :-( can you elaborate??
Anytime you have a variable and you put ++ at the end, that variable is incremented by one. So, if i=3 and then you say i++, then i==4.

I dont know enough about coding to work from the suggestion. It will all have to be done server side if poss.... I just need the html/java to call a file get a number and bang it into the subject, then boost the number up by 1.
Any more suggestions???
html/css cannot do this. You need to ask on one of the programming boards.

Does anyone know of a way to quickly validate an HTML web

I have to start of apologising because this question arose in a context

I have a web form where a client can select which site members to send
an email to.
This form is populated from the contents of the member table, so the
form can have 0-x names listed on it depending on member expiration dates.
When the form is submitted, the code loops through the form contents and
sends an email to those members that meet the selected criteria.
All this worked perfectly when I was sending text emails, but since I

Hi,
I have recently added tried to update the feedback form on my
page to be sent in HTML format.
Problem is that when its submitted, I get the mail without the
variable input, just the variable name.
I have added the text version to it and both send fine, but still only
the text version includes the variable input.
