Test the value of a database field using conditional statement for empty

[ez2c]

hi,
I am trying to test if a user enters nothing in a field in my db form the php script will enter something like ' not entered ' in this field in the db.
I tried something like below but get an error message. I know I need some type of conditional statement but don't know how to put it together.

if (some_array[some_field] != "")
{
do something
}

check to see if the field is empty or not. if it is empty, it'll put something there.

any help would be appreciated! thanks in advance!

Can you list the whole code so we can take a look at what may be the problem?

It's safer to use empty().

PHP Code:

if($_POST['submit']) { 
   if((empty($_POST['field1'])) || (empty($_POST['field']))) { 
    echo "empty field"; 
     }  else { 
         // submit data 
         } 
} else { 

echo "FORM HERE"; 
// make sure you have 'name=submit' in your submit button 
} 


cheers
