    mysqli connection not cooperating

    All,

    I've been programming PHP for about a year now, but for some reason, I can't connect to one of my databases.

    PHP Code:
    $con mysqli_connect("localhost""timw79_rfid""xpress13""timw79_rxrfid");if (mysqli_connect_errno()) {  echo "Failed to connect to MySQL: " mysqli_connect_error();}
    $result mysqli_query($con,"SELECT AssignedMachine FROM TagAssignments WHERE TagID=$tag1");


    while(
    $row mysqli_fetch_array($result)) {  echo $row['AssignedMachine'] . " " $row['TagID'];  echo "<br>";} 
    I have confirmed that $tag1 is reporting correctly. I checked spelling and capitalization. I'm stumped on this one. I am getting the error:
    Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in /home3/timw79/public_html/rxrfid/piupload/addmachinenames.php on line 76

    Where have I gone wrong?

    I have attached the PHP MyAdmin page for this table in case it is needed.

    Add a check to see if you query ran - it didn't. Echo out the error message from it.

    PS - If you're posting here you should be using:

    error_reporting(E_ALL);
    ini_set('display_errors', '1');


    at the top of ALL php code while you develop it!

    Ah yes, I forgot to report the errors. I was able to get the query working. I appreciate the reminder.
