Hello Guys,

missing load the form again by focusing on the wrong field.Say i don not
enter my address so when the form loads everything else is saved and the
form points to address field.

Thanks

Aditya

Typically, you would direct the form back to itself. Then at the top of
the form, you'd put a test to determine if the form has been processed
before or if this is the first time through. Then you make your decision
about missed fields, etc. Like this:

== someform.php ==

if (empty($_POST)) {
load_some_values_or_not();
}
else { // form has entered data
$okay = process_for_errors();
if ($okay) {
store_the_data();
header("Location: success.php");
exit();
}
}
?>
HTML crap goes here...

== end of someform.php ==

You'll notice that if there are entry errors, execution falls through.
In that case, you'll need to do something like this for fields:



so that the entered data shows up in the fields. First time through, the
value attribute will yield nothing.

You need Javascript for that not PHP. PHP is server side, javascript is
client side (browser).

He doesn't say anything about not reloading the form... in fact he
explicitly says "when something is missing load the form again". This
suggests a server request and not JavaScript. Either way... validation
can occur either in JavaScript or PHP... but it should ALWAYS occur in
PHP regardless of any JavaScript validation.

Cheers,
Rob.

I think just do some form validation tutorials (google for them).
These will help you to understand the validation process in more detail.

I still like


// includes go here

if(isset($_POST['submit'])){
process_form();
}else{
show_form();
}//end if

function process_form()
{
//receive the data, validate and store the data in the db goes here
//feel free to add more functions that you could re-use in other parts
//of the app


}

function show_form($data='', $errors='')
{
//code to show the form goes here
//$data and $errors could be passed in from the above function if
//there are issues with the data validation (no image, data missing etc)


}

for simple pages. Its a mini MVC where the code could post the data
back to the form with error message to indicate to the user what
should be done.
