php - unsetting array by key within WP Loop -


i trying unset array has same [key] post id within wordpress loop, using following...

<form action="" method="post"> <button class="btn btn-danger btn-l pull-right" type="submit" name="exercisedelete"    value="exercisedelete">yes</button> </form>  <?php $exid = the_id() ?>  if (!empty($_post['exercisedelete'])) { echo ' <script type="text/javascript"> location.reload(); </script>'; unset($_session['collection'][$exid]);          } ?>

i have performed echo on exid @ stages on , picking correct title. if hard code $exid in unset works fine also.

the problem having when $_post sent unsets final key in $session[collection] rather 1 correct key.

i have had working before think possibly not best method. there better way of running functions on buttons rather using $_post??

many in advance.

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;...
