OR problem

[reetspetit]

I am trying to hack a bit of code for a form. Basically, I want the user to either fill in a telephone number OR an email address, but not necessarily both. If neither are filled, in the form colours the fields in red and issues a warning

Effectively this :

if ((if statement1) OR (statement2))

The following are the two statements that need to be or'd :

//Statement 1

if((empty($_POST['telephone'])) {
$errormessages[] = 'Please enter your telephone.';
$errorfields[] = 'telephone';
}

// Statement 2

if(empty($_POST['email'])) {
$errormessages[] = 'Please enter your email address.';
$errorfields[] = 'email';
} else {
if(!eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $_POST['email'])) {
$errormessages[] = 'Please enter a proper email address for yourself.';
$errorfields[] = 'email';
}
}

Just had a thought. Should it be :

if ((if not statement1) AND (if not statement2))

???

Hmm. Whole damn thing needs juggling methinks !

Just can't quite get my head round doing it. Any help would be greatly appreciated.

You only consider missing input as an error if both fields are not entered. If the email field is entered, you consider it an error if the email fails to validate.

if (empty($_POST['telephone']) && empty($_POST['email'])) {
	$errormessages[] = 'Please enter your telephone.';
	$errorfields[] = 'telephone';
	$errormessages[] = 'Please enter your email address.';
	$errorfields[] = 'email';
} elseif (!empty($_POST['email'])
	&& !eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $_POST['email'])) {
	$errormessages[] = 'Please enter a proper email address for yourself.';
	$errorfields[] = 'email';
}

There is a god after all !

Many thanks.

Amended slightly as follows :

if (empty($_POST['telephone']) && empty($_POST['email'])) {

// only need the error message once

$errormessages[] = 'Please enter your email address or telephone.';

// 

$errorfields[] = 'telephone';
$errorfields[] = 'email';

} elseif (!empty($_POST['email'])
&& !eregi("^[a-z0-9\._-]+@+[a-z0-9\._-]+\.+[a-z]{2,3}$", $_POST['email']))             {
$errormessages[] = 'Please enter a proper email address for yourself.';
$errorfields[] = 'email';
} 

Thanks once again.
