Nematode128 Posted April 14, 2020 Share Posted April 14, 2020 (edited) Hello I'm currently working on a staff page for my website and I'm having trouble with a function not working corrrectly. The function is supposed to display an error message if the logged in user isn't a high enough level however it doesn't seem to be correctly getting the users rank level correctly cause in the error message it returns "You have a rank of" instead of "You have a rank of x". Here are my codes below maindir/header.php $username = $_SESSION['username']; $sql = "SELECT * FROM users WHERE username=? LIMIT 1"; // SQL with parameters $stmt = $link->prepare($sql); $stmt->bind_param("s", $username); $stmt->execute(); $result = $stmt->get_result(); // get the mysqli result $user = $result->fetch_assoc(); // fetch data function verify_staff() { if ($user['rank'] <= '2') { echo " <div class='alert alert-danger' role='alert'> You're not supposed to be here. You have a rank of " . $user['rank'] . " </div> "; exit; } } /maindir/staff/index.php <?php require '../header.php'; verify_staff(); echo "Staff panel"; require '../footer.php'; ?> Edited April 14, 2020 by Nematode128 Quote Link to comment https://forums.phpfreaks.com/topic/310576-function-help/ Share on other sites More sharing options...
gw1500se Posted April 14, 2020 Share Posted April 14, 2020 First do not use * in your query. Only ask for the columns you intend to use. As for your question, you need to make sure the query is returning what you expect. Do this to verify it: echo "<pre>"; print_r($user); echo "</pre>"; Quote Link to comment https://forums.phpfreaks.com/topic/310576-function-help/#findComment-1576832 Share on other sites More sharing options...
NotSunfighter Posted April 14, 2020 Share Posted April 14, 2020 Why are you pulling everything from the db with the * when all you want is the rank? In your echo you are putting a double quote inside a double quote. => You have a rank of " . $user['rank'] . " Quote Link to comment https://forums.phpfreaks.com/topic/310576-function-help/#findComment-1576833 Share on other sites More sharing options...

Barand Posted April 14, 2020 Share Posted April 14, 2020 The variable "$user" does not exist inside your function (variable scope!). Pass it in your function call. E.G. verify_staff($user); Quote Link to comment https://forums.phpfreaks.com/topic/310576-function-help/#findComment-1576839 Share on other sites More sharing options...

Pass it in your function call. E.G. verify_staff($user); Okay that makes sense. Would I have to run another sql query inside the function then?

Barand Posted April 14, 2020 Share Posted April 14, 2020 $user is already the output from a query you have just run. Quote Link to comment https://forums.phpfreaks.com/topic/310576-function-help/#findComment-1576844 Share on other sites More sharing options...
