Question

echo $link['Theme'];
 if(empty($link['Theme']))
 global $Theme;
 { echo $Theme; };
 if(empty($Theme))
 { echo 'default'; };   

$link pulls data from the database. $Theme is an optional variable on a higher page that I would really like to have as an override for the Theme stored on the database.

Currently, I set it up to print the $Theme if the Theme from the database is NULL.

I tried adding another if statement for if there was no value in $Theme, it would simply print ‘default’ to load the default design.

Currently the last if statement makes it print $link['Theme'} + default (like spacedefault instead of just space or default)

Can someone help me with this? I’m not great at php yet. Thanks!

I believe you’re looking for the following conditionals

global $Theme;
if (empty($link['Theme'])) {
  if (empty($Theme)) {
    echo 'default';
  } else {
    echo $Theme;
  }
} else {
  echo $link['Theme'];
}

Here it is in two lines of code, if you’re looking to use inline conditionals

global $Theme;
echo empty($link['Theme']) ? (empty($Theme) ? 'default' : $Theme) : $link['Theme'];
