Self submitting form and posting errors

[TheFilmGod]

How do you code a self submitting form that posts all errors (if there are any errors) in a neat way?

 

I know how to code such a form without a problem... I just don't know how to code it WELL/shorthand?

 

Do you put things into a function? Is there some advanced php template producer? Just wondering.

I've always gone with an error array.... so put the errors into an array and check it later

 

$error = array();

if (isset($_POST['submit'])) {									// get the session that was posted
// 
if (empty($_POST['field1'])) {							
	$error[] = 'field one';			
} else {												
	$field1 = trim($_POST['field1']);						
}

// 
if (empty($_POST['field2'])) {							
	$error[] = 'field two';			
} else {												
	$field2 = trim($_POST['field2']);						
}

// 
if (empty($_POST['field3'])) {							
	$error[] = 'field three';			
} else {												
	$field3 = trim($_POST['field3']);						
}

if (empty($error)) {
	// put in DB or whatever...
}
else {
	foreach ($error as $errorMsgArr) {
		echo ('There was an error, check ' . $errorMsgArr . '<br />');
	}
}
}

 

Of course the foreach can be put into a function and that function can be called upon at any time. Also, I tend to build this around a class that will process all the data. This is how I tend to process my data, hope it works, or helps!

You could use any one of the many frameworks.  I'm most familiar with Zend (http://framework.zend.com) and I know that their form class(es) can do what you want.

 

They use an especially nice decorator format that makes things easy to change.  Padriac Brady wrote a nice tutorial about ZF a while back: http://blog.astrumfutura.com/archives/367-Example-Zend-Framework-Blog-Application-Tutorial-Parts-1-8-Revisited.html
