Instead of testing the value of your variable, object, array or others for the empty string value, you should use the php function empty($var), witch does not throw a notice or warning if the variable does not exist. The php function isset($var) can also be used, but it does not test the value at all, thus isset($var) will return true.
<?php
// This will throw a Notice if the title property does not exist:
if ( $wptreehouse_profile->badges[$i]->courses[1]->title != '' ) {
// do stuff if title is not empty
}
//This will check if the property exists and if the value is empty or false:
if ( !empty( $wptreehouse_profile->badges[$i]->courses[1]->title ) {
//do stuff if title exists and is not empty
}
//This is a longer way to do it:
if ( isset( $wptreehouse_profile->badges[$i]->courses[1]->title ) &&
$wptreehouse_profile->badges[$i]->courses[1]->title != '' ) {
//do stuff if title exists and is not empty
}
?>
Even though all of these will give the same result, all types of notices and warnings should be avoided.
