[SOLVED] input validation error

[gwolff2005]

hi guys,

maybe something really simple, but i dont get it.

I declare variables at the beginning of the session. Later I want to show a graph to the user (if the data is in mysql), if they are not stored in mysql a text should come up, saying: "You need to do the test." Still it does not work.

My session variable is

$_SESSION['MM_resultsmo'] = $row['resultsmo'];

and my code is:

 

if (!empty(MM_resultsmo)){
echo "You need to do the test";
} else {
echo " " . $_SESSION['MM_resultsmo'];
}

 

What is wrong???

[trq]

if (!empty($_SESSION['MM_resultsmo'])) {
  echo "You need to do the test";
} else {
  echo " " . $_SESSION['MM_resultsmo'];
}

That does not work. Even the variable is in the database it just shows "You need to do the test. As a control I displayed the variabel in another field next to it, so the variable works, but not in this code.

it would .. !empty() is like saying, "not empty".  think about it.

 

if (empty($_SESSION['MM_resultsmo'])) {
  echo "You need to do the test";
} else {
  echo " " . $_SESSION['MM_resultsmo'];
}
