php - Why do I get Call to a member function bind_param() on a non-object...? -


i making game class , have added commenting system go it. wanting add ability report comment.

i have added column in comments table called report_active , idea set 1 when active (meaning has been reported) , 0 when isn't. list in admincp of comments active report on them.

i have made file called report_comment.php intend used run queries redirect page.

this report_comment.phppage:

<?php require_once('db_connect.php'); require_once('security.php');  if (isset($_get['id'])) {         $report_active = 1;         $id            = $_get['id'];          $select = $db->query("select * comments id = ?");         $select->bind_param('i', $id);         if ($select->execute()) {                 if ($select->num_rows) {                         // run update query                         $update = $db->query("update comments set report_active = ? id = ?");                         $update->bind_param('ii', $report_active, $id);                         if ($update->execute()) {                                 header('location: comments.php');                                 die();                         }                 }         } } ?>

what doing wrong? error returned with:

fatal error: call member function bind_param() on non-object

$select = $db->query("select * comments id = ?");                ^^^^^---execute query

you want

$stmt = $db->prepare("select * comment id = ?");              ^^^^^^^---note diff

instead. plus, should checking failure, e.g.

if ($stmt === false) {    die("prepare failed error: " . $db->errorinfo); }

or similar particular db library.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
