I’d like to display other text in else statement but it seems like the value or html in IF statement in my num_rows are displaying in the else statement as well.

queryChecker = "SELECT SUM(user_rating) as totalrating,  COUNT(user_rating) as user_ratings FROM tbl_userfeedback, tbl_users WHERE tbl_userfeedback.research_uid = '" .row['research_uid'] . "' 
AND tbl_users.user_uid = '" . _SESSION['user_uid'] . "'"; // '" .row['research_uid'] . "'"
sqlChecker = mysqli_query(conn, queryChecker); if (sqlChecker) {
    if (getNumRows = mysqli_num_rows(sqlChecker) > 0) {
        while (loopValue = mysqli_fetch_assoc(sqlChecker)) {
                getavg =loopValue['totalrating'] / loopValue['user_ratings']; ?>             <div class="container" id="wrapperContainer">                 <div class="card">                     <div class="card-header">                         <h3 class="text-center">Featured</h3>                     </div>                     <div class="card-body">                         <h5 class="card-title">This is the summarized and brief feedbacks of all users....</h5>                         Currently, there's a <b><?php echoloopValue['user_ratings'] ?></b>

However. Whenever I try to view other research all of them are going to the while statement... PS: therow['research_uid'] is just the research_uid.

If the research does not existing yet in the tbl_userfeedback this is what it says.

Warning: Division by zero in (directory)helper_getResearchFeedback.php on line 12"

Please do correct me if I am wrong I do not know if I am wrong in conditional statement or in my SQL Query.
