Redirecting/Including If Array Value Not Set

[phprocker]

Hey all.  I have a form with inputs "menuitem[]" array.  Upon no user input to one of these fields I want to set a variable error and include the form generation page.

 

Is my following code a feasible way to do this?

 

foreach($_POST['menuitem'] as $value)
{
if(!isset($value) || $value == "")
{
 	$emptyvalue = TRUE;
}
}

if ($emptyvalue)
{
$erroralert = "You must fill in all the form fields! Please try again!";	
include "views/addmenus.php";
exit();
}

 

If works but just a bit unsure about it.

 

Cheers!

If you know it is the form of an array, might as well use the empty() function.

if(empty($_POST['menuitem']) && is_array($_POST['menuitem']))

That works to check if the array is there, but I'm talking about individual array values.  My code works I just wanted an experts opinion on the method I used and if there is a better way to achieve it.
