"</td>";                 echo "<td><a href='edittrainingcourse.php?id=".$row['trainingid']."'><strong>edit</strong></a></td>";                 echo "<td><a href='deletetrainingcourse.php?id=".$row['trainingid']."'><strong>delete</strong></a></td>";                  echo "</tr>\n";             }             print "</table>\n";         }     } catch (pdoexception $e) {         echo "query failed: " . $e->getmessage();     }      }   catch (pdoexception $e) {     //$conn->rollback();     // if raised exception in our transaction block of statements,     // roll work performed in transaction     exit('<p>unable complete transaction!</p>'.$e->getmessage());      }

i think answer lies the

id=".$row['trainingid']

section im not sure how handle that.

thanks , help!

you have create edittrainingcourse.php , deletetrainingcourse.php.

in each of those, need check existence of $_get['id'] represents ?id=xxx found in url.

verify id passed indeed integer, use it:

if ( is_int($_get['id']) ) {     $trainingid = $_get['id']); } else {     die('bad id given.'); }

now perform queries using $trainingid.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
