php - SOLVED: Why can't I count rows? -

-

solved: after fixing typo, didn't work how wanted it. fixed it. error in $ip2. since http_x_forwarded_for doesn't have input database recalled " " existing ip , didn't add new vote. fixed adding if ($ip2="") statement , adding votes.

edit: changed typo, seems give me "you voted" page proxy change ip.

edit 2: checked something: voted once , works gets added database, vote proxy gives ip1 still tells me voted already. can vote once.

so have code, returns nothing:

<?php $con = mysqli_connect("localhost","root","password","database");  $ip1 = $_server['remote_addr']; $ip2 = $_server['http_x_forwarded_for'];  if (mysqli_connect_errno())   {   echo "unable connect: " . mysqli_connect_error();   }  $count1 = mysqli_num_rows(mysqli_query($con, "select * votes voteip1 = '$ip1'")); $count2 = mysqli_num_rows(mysqli_query($con, "select * votes voteip2 = '$ip2'"));  if (($count1 > 0) || ($count2 > 0))     {     echo "you voted, can leave page.";     mysqli_close($con);     } else      {     $sql="insert votes (vote, voteip1, voteip2)     values      ('$_post[vote]','$ip1','$ip2')";      if (!mysqli_query($con,$sql))         {         die('error: ' . mysqli_error($con));         }      echo "thanks voting, can leave page.";     mysqli_close($con);     } ?>

i have tried many different things. can please tell me doing wrong.

ps sorry english, it's not first language , still learning

PHPMotion implementation - URL based videos (Hosted on separate location) -

-
i have implement video collection website users of specific isp. site hosted on public web-server movies hosted on local isp server. user of isp + general visitors can see available movies; isp's users able play them. player on site point url of local machine ( http://192.x.x.x/movies/mymovie.mov ) private class (192.x.x.x) accessible isp user. question: possible phpmotion script? or need custom work. if possible, can please suggest available mods? phpmotion require modifications able handle this. uploading, conversion, thumbnail generation, , playback pretty static in phpmotion. really though, rather modding entire upload , conversion process, if created quick custom form add entries phpmotion database (maybe include thumbnail upload), tweaked playback paths, should go on phpmotion side of things. assume had videos in format player handle (such flv or mp4).

getting video play cross platform using example video.js bit of fuss. in days when video should embedded use embed windows media player, work out of box on windows. since it's today old ie on windows doesn't support video tag experimented using windows media player fallback, , work well. what wonder here is, why haven't else solution? have missed something? code small, there's no flash files, cross domain issues or need of server working. works. so before develop further , add custom control , subtitles support wonder say. the code looks this: <video id="myvideo" style="width:640px; height: 360px;" autoplay data-wimpsource="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4"> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.mp4" type="video/mp4" /> <source src="http://esd.volvocars.com/dc/cdn/video/birds-on-a-wire.webm" type="video/webm" />
