CATCHING INTERACTIVE DATA - HTML5 - page 334

will be very simple and provide users with a comment section they can use for your Web
page.

h e basics of making an e-mail application center around the mail() function in PHP. h e
mail() function expects three or four parameters. In the i rst e-mail application, only the
i rst three are used.

A SIMPLE E-MAIL APPLICATION
h e i rst thing you want to do in an e-mail application is set up the HTML5 portion of your
HTML5-PHP pair to provide a clear entry for users. Using the validation checking built into
some of the input forms ( onInvalid ), you can prevent users from inadvertently sending an
e-mail, phone number, or URL or other form data that are incorrectly formatted. So, this i rst
HTML5 e-mailer will (again) use the e-mail input form and use the onInvalid event
handler. h e following program ( EZmailer.html in this chapter's folder at www.wiley.
com/go/smashinghtml5 ), should be fairly familiar.

{
alert(“Hmmmm... It seems that the e-mail entry has something out of sort. . . .
Please take a look at it and see if you can fix it up.”)
