This is the part of the PHP code I am having the issue: $query = "SELECT * FROM clients where idcard = '$idcard'"; $result = mysqli_query($dbc, $query) or die("Error quering database."); if(mysqli_fetch_array($result) == False) echo "Sorry, no clients found"; while($row = mysqli_fetch_array($result)) { $list = $row['first_name'] . " " . $row['last_name'] . " " . $row['address'] . " " . $row['town'] . " " . $row['telephone'] . " " . $row['mobile']; echo "
"; echo $list; } Even if I insert an existing idcard value I get no output when there is the if statement, an incorrect idcard displays "Sorry, no clients found" fine. However if I remove the if statement if I enter an existing idcard the data displays ok. Can you let me know what is wrong with the code please ? Thanks
