Hello everyone, I am new to php coding and i am currently trying to check for duplicate data when inserting new values (i.e. a question) in mysql database table. I keep getting this error 'Warning: mysqli_num_rows() expects exactly 1 parameter,2 given in'. Below is the code i am currently working with. Thanks in advance <?php session_start(); $link = mysqli_connect("elephant.ecs.westminster.ac.uk", "w1268094", "euMm27FZwZDK", "w1268094_0"); ?> <?php //Error reporting due to long script error_reporting(E_ALL); ini_set('display_errors','1'); ?> <?php ob_start(); //Add question to table If (isset($_POST['question'])) { $question = mysqli_real_escape_string($link, $_POST['question']); $date = mysqli_real_escape_string($link, $_POST['questiondate']); //See if question is identical to another question in the table $sql = mysqli_query($link,"SELECT pQuestionNo FROM presidentQuestion WHERE pQuestion='$question'LIMIT 1"); $questionMatch = mysqli_num_rows($link, $sql); //count the output amount if ($questionMatch>0){ echo 'Sorry you tried to place a duplicate "Question" into the table, <a href="inventory.php">Click here</a>'; exit(); } //Add the question to the database $sql = mysqli_query($link,"INSERT INTO presidentQuestion (pQuestion,pDate) VALUES ('". mysqli_real_escape_string($link, $question) ."','". mysqli_real_escape_string($link, $date) ."')") or die (mysqli_error($link)); header("location: inventory.php"); exit(); } ?> <?php //Grabs the whole queston list $question_list=""; $sql = mysqli_query($link,"SELECT * FROM presidentQuestion LIMIT 0,10") or die(mysql_error()); $questionCount = mysqli_num_rows($sql);// count the output amount if($questionCount>0){ while($row = mysqli_fetch_array($sql, MYSQLI_ASSOC)){ $question = $row["pQuestion"]; $date = $row["pDate"]; $question_list .= "$question <br/>"; } }else{ $question_list = "There are no questions in the inventory yet"; } ?> <?php $prop_id = $_GET['prop_id']; ?>
