Implementing forms with ASPI think it's safe to say that every site needs a form - a contact or tell-a-friend form to send email, a Search form to search your database, or some sort of data entry form - probably all of these!As you'll soon see, the framework for all these forms is the same. Once you've written one, the rest are easy - it's just copy and paste! The steps to follow are: display form
v
validate data
v
process data
v
[display form] |
Below is the code that I use to implement this framework. Every form uses some variation of this - some don't need any validation, others always display the form again. But each form starts with the code below. var bSubmitted = (Request.Form.Count > 0);
var sName = 'egghead';
// has the form been submitted?
if ( bSubmitted )
{
// get the data from the form...
sName = '' + Request.Form ( "name" );
// validate the name
if ( !sName.length )
{
Out ( 'You must enter a name<p>' );
// pretend the form hasn't been sent yet
bSubmitted = false;
}
}
// show the form if not submitted yet
if ( !bSubmitted )
{
Out ( 'Here\'s a simple form.' );
Out ( '<form action="FormPage.asp" method="post">' );
Out ( 'Name: ' );
Out ( '<input type="text" name="name" size="10" value="' + sName + '">' );
Out ( '<input type="submit" value="Display name">' );
Out ( '</form>' );
}
else
{
// process data
Out ( 'Hi ' + sName );
}

Take a moment to glance over the code above, then I'll step you through this code, line-by-line, and examine what is happening. Part 2: The framework... |
