php checking Prepared statements in if statements

Question

Hello I am currently having problems with if statements in php with prepared statements, no matter what I enter my when checking get_result my statements are always true. I honestly have no idea what Im doing I am very new to php and the concept of prepared statements.

$searchtext= $_POST['search-box'];
$sqlName= $connect->prepare("SELECT * FROM SearchPG WHERE PGName LIKE ? ");
                $sqlName->bind_param("s", $searchtext);
                $sqlName->execute();

                $NameResult = $sqlName->get_result();

                $sqltext= $connect->prepare("SELECT * FROM SearchPG WHERE PGKeywords LIKE ? ");
                $sqltext->bind_param("s", $searchtext);
                $sqltext->execute();

                $TextResult = $sqltext->get_result();
if($NameResult->num_rows > 0 || $TextResult->num_rows > 0){
                        if($NameResult->num_rows > 0 ){
                            echo "made it into sqlname";
                            while($rs = $NameResult->fetch_assoc()){
                                echo "name result";

                                ?>
                                <div class="row resultcontent">

                            }


                        }

I have tried if(!$result), if($result->num_rows>0), if($result->affected_rows) and others but none seem to work has anybody got any idea what I am doing wrong

Answer 1

There's a good chance you don't have the "native driver" (mysqlnd) installed, which is necessary for the get_result() method.

cf. http://php.net/manual/en/mysqli-stmt.get-result.php

Try using PDO:

<?php

$dbh = new PDO(
  'mysql:dbname=myDatabase;host=myHost', 
  'myUsername', 'myPassword');

$stmt = $dbh->prepare('SELECT * FROM SearchPG WHERE PGName LIKE ? ');
$stmt->bindParam(1, $searchtext, PDO::PARAM_STR);
$stmt->execute();
$result = $stmt->fetchAll();
foreach($result as $row) {
    print_r($row);
}

Answer 2

For anybody that maybe new to php, prepared statements and having similar problems to me, I solved my problems by switching get_result to store_result after changing code to suit store_result things seemed to work flawlessly. Here is my new code it still needs some fixing and cleaning up but I hope this helps someone in need.

$sqlname= $connect->prepare("SELECT PGID, PGName, PGUrl, PGImgUrl FROM SearchPG WHERE PGName LIKE ? ");
                $sqlname->bind_param("s", $searchtext);
                $sqlname->execute();
                $sqlname->store_result();

                $sqltext= $connect->prepare("SELECT PGID, PGName, PGUrl, PGImgUrl FROM SearchPG WHERE PGKeywords LIKE ? ");
                $sqltext->bind_param("s", $searchtext);
                $sqltext->execute();
                $sqltext->store_result();
if($sqlname->num_rows > 0 || $sqltext->num_rows > 0){
                        if($sqlname->num_rows > 0 ){
                            $sqlname->bind_result($id, $name, $url, $imgurl);

                            while($rs = $sqlname->fetch()){


                                ?>
                                <div class="row resultcontent">

                    }
