Using foreach to echo error. But error is given when not set...

[cs.punk]

Uhm Im kinda stuck...

 

 

 

<?php
if (isset($error))
 {echo "<p class='error'>The following errors were found:</p>
 			";
	print_r ($error);

  // missing fields	  
  $error['empty'] = array();
  foreach ($error['empty'] as $v)
  	{echo "<p class='error'>$v</p>";
	}

  // invalid size
  foreach ($error['size'] as $v)
  	{echo "<p class='error'>$v</p>";
	}

  // invalid format
  foreach ($error['format'] as $v)
  	{echo "<p class='error'>$v</p>";
	}
 }


// Coming from the xhtml form
   if (!empty($_POST['title']))
   	{$rdata['title'] = mysqli_real_escape_string($con, $_POST['title']);
}
   else
    {$error['empty'][] = "You have not entered a title."; 
}

   if (!empty($_POST['desc']))
   	{$rdata[''] = mysqli_real_escape_string($con, $_POST['desc']);
}
   else
    {$error['empty'][] = "You have not entered a descreption."; 
}
?>

 

But every time no error from one array is found but an error is found form another is still uses foreach on it.. and since its not set as an array it gives an error. I cant use

$error['empty'] = array();

because it would blank it when there is an error...

A isset for each array? Is there an easier way?

Try checking your variables against is_array before entering any foreach.
