Question

I am having trouble displaying results from a SQL query. I am trying to display all images and prices from a products table.

I am able to display the echo statement “Query works” in the browser. But, the results are not displaying in the browser.

        if ($count > 0) {
            echo "Query works";
        } else {
            echo "Query doesn't work" ."<br/>";
        }

PHP Code:

$con = getConnection();
        $sqlQuery = "SELECT * from Products";

        // Execute Query -----------------------------           
        $result = mysqli_query($con, $sqlQuery);
            if(!$result) {
                echo "Cannot do query" . "<br/>";
                exit;
            }

            $row = mysqli_fetch_row($result);
            $count = $row[0];

            if ($count > 0) {
                echo "Query works";
            } else {
                echo "Query doesn't work" ."<br/>";
            }

          // Display Results -----------------------------

            $num_results = $result->numRows();

            for ($i=0; $i<$num_results; $i++) {
                $row = $result->fetchRow(MDB2_FETCH_ASSOC);
                echo '<img src="'.$row['Image'].'>';
                echo "<br/>" . "Price: " . stripslashes($row['Price']);

}

Screenshot 2: removed the images from the database, and used a filepath instead

Screenshot 3: print_r($row)

try

$sqlQuery = "SELECT * from Products";

        // Execute Query -----------------------------           
        $result = mysqli_query($con, $sqlQuery);
            if(!$result) {
                echo "Cannot do query" . "<br/>";
                exit;
            }

            $row = mysqli_fetch_row($result);
            $count = $row[0];

            if ($count > 0) {
                echo "Query works";
            } else {
                echo "Query doesn't work" ."<br/>";
            }

          // Display Results -----------------------------

            $num_results =mysqli_num_rows($result);

            for ($i=0; $i<$num_results; $i++) {
                $row = mysqli_fetch_assoc ($result);
                //print_r($row);
              echo '<img src="'.$row['Image'].'>';
                echo "<br/>" . "Price: " . stripslashes($row['Price']);
            }
