Creating album for mysql and php online photo album -

-

i creating mysql backed online photo album , using php access mysql database, having trouble trying create form lets users create new album, far have following code: 

<h1>my photo collection</h1> <h3>add, search ,  browse through our collection!</h3> <section id="collection"> <h4>create album</h4> <form method='post'>         <?php         require_once 'config.php';          $mysqli = new mysqli(db_host, db_user, db_password, db_name);         if(isset($_post['title'])){         $name = $_post['title'];         if(empty($name)){              echo "please enter album name <br/>";         } else{             $mysqli->query("insert albums values('', '$title')");             echo "album created <br/>";         }     }     ?>     album name: <input type="text" name="title" /> <input type="submit" value="create" /> </form> </section>

my schema ' albums' table is: title, date_created, date_modified (time stamp), albumid (primary key)

further questions: how allow user enter date no form (and make sure in correct format), how date_modified timestamp work (do need put in form?)

i using mysqli , not mysql in php queries. far, code returns "undefined object 'title'" can me , figure out i'm doing wrong code?

thank you!

currently, $title undefined, assigned $_post['title'] $name. , since you're using mysqli api, use prepared statements instead.

as date, use now()

<?php  require_once 'config.php';  $mysqli = new mysqli(db_host, db_user, db_password, db_name);  if(isset($_post['submit'])) {     if(empty($_post['title'])) {         echo 'please enter album name <br/>';     } else {         $name = $_post['title'];         $insert = $mysqli->prepare('insert albums (title, date_created, date_modified) values(?, now(), now())') or die($mysqli->error);         $insert->bind_param('s', $name);         if($insert->execute()) {             echo 'album created <br/>';         } else {             echo $mysqli->error;         }      } }  ?>  <h1>my photo collection</h1> <h3>add, search ,  browse through our collection!</h3> <section id="collection">     <h4>create album</h4>     <form method='post'>         album name: <input type="text" name="title" />          <input type="submit" name="submit" value="create" />     </form> </section>

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
