Variables within a URL

[me4400]

How do you pass variables through a URL?

For example:

http://www.somewhere.com?BDate=txtBDate&EDate=txtEDate

Basically, I have two text boxes, one with Beginning Date and one with Ending Date, that the user fills in and I want to pass to the submission page.

Simply specify "GET" as the METHOD for your form. The browser will format the values of the form fields correctly, then put them into a query string appended to the ACTION you specified for the form.

Decoding them, and using them, is another story altogether... for that, you'll need a server-side application (Perl/CGI, ASP, PHP, ColdFusion, etc). You can decode the URL variables with JavaScript, but this will severely limit you since not all user agents have JavaScript enabled.

after the ?
split them (&)
u get
name=value

those are retrieve by server-side languague
here is a basic perl function to do so
link : .html?myvar=2

sub get_form {
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@pairs = split(/&/, $buffer);
foreach $pair (@pairs) {
 ($name, $value) = split(/=/, $pair);
 $value =~ tr/+/ /;
 $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
 $value =~ s/<!--(.|\n)*-->//g;
 $FORM{$name} = $value;
}

now u check the 'myvar' value like in this example

if ($FORM{myvar} == 0) {
 # do something
} else {
 # not 0 do other
}
[/code}

or u can use cookies to pass value too

ack! complicated language. if you use asp they all asume thier variable names automaticly. all you have to do is use them. for example, a page like this:

page.asp?var1=value1&var2=value2

those variables could be recived like this:

hey everyone, var1 equals <%=var1%> and var2 equals <%=var2%>!

much easyer X-)
