Num_Rows中未选择任何数据库

Question

Got a strange error saying that I'm not connected to a database while running a mysqli_num_rows query. Here is the code:

    <?php include("php/functions.php"); ?>
<?php
if(isset($_GET['verification']) && !empty($_GET['verification'])){  
    // Verify data  
    $hash = mysqli_real_escape_string($con, $_GET['verification']); // Set hash variable  

    $search_sql = "SELECT 'hash', active FROM members WHERE hash='".$verification."' AND active='0'";   
    $search_res = mysqli_query($con, $search_sql);
    $match = mysqli_num_rows($search_res);

Any ideas why this isn't working?

Answer 1

<?php include('functions.php'); ?>

Also, make sure you have your closing ?> tag in the correct place.
