I'm having a problem creating a dropdown list and populating it with information from a database. When I display the page below I get this PHP code displayed in place of the drop down menu:
"
\n"; while ($row = mysqli_fetch_array($result)) { $str .= '' . $row . '
' . "\n"; } $str .= ''; echo $str ?>"

Seems to be a simple mistake :

Add </option> at line 50 and 75 :)

First, solve the problem. Then write the code.

Yes at 50 & 75

$str .= '<OPTION VALUE=' .  $row['conditionid'] . '>' . $row['condition_name'] . '</OPTION>'.'<BR>' . "\n";

it's still not working. now it says this:
Select A System "; while ($row = mysqli_fetch_array($result)) { $str .= '' . $row . ''.'
' . "\n"; } $str .= ""; echo $str ?>
Select A Genre
\n"; while ($row = mysqli_fetch_array($result)) { $str .= '' . $row . ''.'
' . "\n"; } $str .= ''; echo $str ?>
What is the condtion of the game?
\n"; while ($row = mysqli_fetch_array($result)) { $str .= '' . $row . ''.'
' . "\n"; } $str .= ''; echo $str ?>

I know the php works on other pages i've tried. it seems for some reason, the php is not working on this page.

updated code:

Rename the file with a php extension (e.g. page.php). If you've already done this - are you sure that the server is running php?

Renaming it took care of the problem, thanks. Now two of the drop down menus work but the system one gives this error:

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, null given in C:\Program Files\IndigoPerl\apache\htdocs\add_game.php on line 22

on line 20 Add

$result = mysqli_query($dbc, $sql) or die( "Could not execute query: $query" );

You are using mysqli_fetch_array($result) on line 22 but $result is not defined when it is executed.
