how to hide code pieces?

[adrianle]

I'm pulling a record from mySQL to display on a page. I need to write something so that if a particular field (say, Address2) is empty in the recordset, to hide the other wise displayed field value on the page. Help?

I'm sure there's a more efficient way to do this, but maybe you could do a set of if statements (if field1 is blank echo all but field1).. if I'm understanding you correctly.. ?

Like this? ..

if (!empty($address1) || !empty($address2)) {
  echo "Here they are.... $address1 + $address2";
} else { 
  //do nothing, or display a warning that one is blank.
}

Thanks for the help.. that defnitely helped with the address question..

 

now, how would I modify this so that if the email field is blank, then the page just skips that line and goes to the next value?

oni-kun gave you most of what you need.  If you look real carefully at how you phrased your original question and how he provided his answer, you just might be able to figure out what you need to change to get it to work...

if (!isset($_POST['e-mail']) || !empty($_POST['e-mail'])) { 
   $e-mail = $_POST['e-mail'];
}

 

Basically like that, so it'll only list or assign the e-mail variable if it is not empty in the database, if it is empty then it'll skip the code completely.
