html - PHP not executing -


so im still beginning learn php , im trying make code upload 2 items,name , age. database "nk" table "players" , display entries in players. whenever hit submit, page reloads show php code , doesn't execute.

<html>  <body>   <form action="db.php" method="post">  name: <input type="text" name="name">  age:<input type="text" name="age">  <input type="submit">    </form>   </body> </html>

and db.php file

<?php  mysql_connect("localhost","noha","noha"); @mysql_select_db(nk) or die( "unable select database");  $name=$_post['name']; $age=$_post['age'];   $result=mysql_query("select * players");  $num=mysql_numrows($result);  mysql_close();  echo "<b><center>database output</center></b><br><br>";  $i=0; while ($i < $num) {  $name=mysql_result($result,$i,"name"); $age=mysql_result($result,$i,"age");  echo "<b>$name $age</b><br>";  $i++; }  mysql_close(); ?>

i'm not sure meaning , i'm guessing. page reloads , show php code , php client not set yet. have checked mysql , apache server running?

a way 

echo 'something'; mysql_connect("localhost","noha","noha");

and see whether code execute

by way $num=mysql_numrows($result); $num=mysql_num_rows($result);

so have server online, maybe should check mysql_select_db syntax

and try use mysqli since mysql deprecated

( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
