  1. Hello, I am working on creating an angular js directive for using HTML5 Canvas My goal is to output a canvas and use Font Awesome icons for writing inside of the canvas. My code is the following, however the problem i have is that the font awesome icons don't seem to render: angular.module('myApp') .directive('customButtonCanvas', ['$document', function($document) { return { restrict: 'A', scope: { width : '=', height : '=', options : '=' }, link: function(scope, element){ console.log(scope); console.log(element); //first lets get the canvas element from our template.... var ctx = element[0].getContext('2d'); ctx.font = "40px FontAwesome"; ctx.fillText("\uf000", 120, 120); console.log(ctx); } }; }]); any help with this will be greatly appreciated. thanks!

  4. I've just looked into some realtime stuff and it looks like Websockets can be good for what i am looking to do. does anyone know weather websockets is the best way for me to go?
  5. Try to use the foreach loop for the entire table....for example: <?php foreach($rotadetails as $rotadetail): ?> <table align="center" border=0 cellspacing=0 cellpadding=0 width=633> <tr> <td colspan=7 valign=top style="height:4px; "></td> </tr> <tr align="center"> <td width="70" rowspan="2">Week <?php echo $i; ?></td> <td width="80" colspan=1 bgcolor="#DBE5F1">Breakfast</td> <td width="80" colspan=1 bgcolor="#DBE5F1">Lunch</td> <td width="80" colspan=1 bgcolor="#DBE5F1">Dinner</td> <td width="80" colspan=1 bgcolor="#DBE5F1">Bed</td> <td width="120" colspan=2 bgcolor="#DBE5F1">Extra Time</td> </tr> <tr align="center" bgcolor="#DBE5F1"> <td width="80" colspan=1>08:00-09:00</td> <td width="80" colspan=1>13:30-14:30</td> <td width="80" colspan=1>17:00-18:00</td> <td width="80" colspan=1>22:00-23:00</td> <td width="120" colspan=1>Start</td> <td width="60">Duration</td> </tr> <tr> <td colspan=1><?php echo date("l",$rotadetail['pa_rotaDate']); ?></td> <td colspan=1><?php echo $rotadetail['pa_hrs0800']; ?></td> <td colspan=1><?php echo $rotadetail['pa_hrs1300']; ?></td> <td colspan=1><?php echo $rotadetail['pa_hrs1700']; ?></td> <td colspan=1 bgcolor="#DBE5F1"><?php echo $rotadetail['pa_hrs2200']; ?></td> <td ><?php echo $rotadetail['pa_rotaETime']; ?></td> <td><?php echo $rotadetail['pa_rotaETimeDur']; ?></td> </tr> <tr> <td colspan=7 valign=top style="height:4px; "></td> </tr> <tr> <td colspan=1 align="right" valign=top>TOTAL </td> <td colspan=1><?php echo $bttot1; ?></td> <td colspan=1><?php echo $lttot1; ?></td> <td colspan=1><?php echo $tttot1; ?></td> <td colspan=1 bgcolor="#DBE5F1"><?php echo $nttot1; ?></td> <td colspan=2><?php echo $ettot1; ?></td> </tr> </table> <?php endforeach; ?>
  6. well what i am trying to do is take the TABLE and convert it into a php array so that i can insert it into a MySQL database.

  8. Hello everyone, I am working on a website and i am using AJAX. I am sending requests to the server constantly to have a "LIVE" FEED.

  9. Hello everyone, i am working on a website that uses facebook api to login with facebook. However i am having a problem with the Javascript and PHP sdk. The problem is that i keep getting an unexpected error which basically expires the facebook Auth Token and then it logs the user out of the website then logs them back in. The code that i am using is below.... <?php require 'facebook.php'; $facebook = new Facebook(array( 'appId' => 'MY_APP_ID_HERE', 'secret' => 'MY_APP_SECRET', 'cookie' => true )); // See if there is a user from a cookie $user = $facebook->getUser(); if ($user) { try { // Proceed knowing you have a logged in user who's authenticated. $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>'; $user = null; } } ?> <!DOCTYPE html> <html xmlns:fb="http://www.facebook.com/2008/fbml"> <body> <?php if ($user) { ?> Your user profile is <pre> <?php print htmlspecialchars(print_r($user_profile, true)) ?> </pre> <?php } else { ?> <fb:login-button></fb:login-button> <?php } ?> <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId: '<?php echo $facebook->getAppID() ?>', cookie: true, xfbml: true, oauth: true }); FB.Event.subscribe('auth.login', function(response) { window.location.reload(); }); FB.Event.subscribe('auth.logout', function(response) { window.location.reload(); }); }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); </script> </body> </html> The error that i get when the user logs out is this: [error] => Array ( [message] => An active access token must be used to query information about the current user. [type] => OAuthException [code] => 2500 ) Can someone please tell me if i am doing something wrong? How can i get the session to NOT expire so fast?
  10. Hello everyone, I have been thinking of making a casino (poker) game for iOS/Android/Website/facebook etc. Basically i want a clone of Zynga Poker app for iphone. The problem is that i'm not sure where to start. Does anyone have any suggestions on where i could start to make an app exactly like Zynga Poker?? I don't have much knowledge about Servers or Application Security. Also, if i need to hire a team to make this work, what type of job positions would be needed?
  11. yes there is khanahk but sometimes when you have a Large database to import, that will not work because of php's limitations. so the best solution for that is to run a LOAD DATA query on the SQL.
  12. For anyone who is trying to do something similar to what i have to do which is to LOAD a large database onto phpmyadmin..... here is what i did to solve my issue..... 1.) Login to cPanel and white list your ip address. ( go to the mysql remote access and enter your ip address) 2.) Download a program called MySQL Work Bench 3.) Connect to MySQL Workbench using the ip address that shows on on the left side of your cPanel (in my case it's a shared ip address because i am on a shared hosting account) 4.) After you have connected, create a table with the same fields that appear in your Large database file. (in my case it is a .csv file) 5.) use a similar query like the one below (i am on my mac, the path should be your own computer's path): in the example below, i am using the table name "targets" and the fields in my table are State,NPANXX,LATA,ZipCode,ZipCodeCount,ZipCodeFreq,NPA,NXX LOAD DATA LOCAL INFILE '/Users/mycomputername/Downloads/2012-8-StandardAreaCodeDatabase-csv/2012-8-StandardAreaCodeDatabase.csv' INTO TABLE targets FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (State,NPANXX,LATA,ZipCode,ZipCodeCount,ZipCodeFreq,NPA,NXX); I hope i was able to help anyone else who had the same problem as me
  13. hello, i am trying to load a large CSV file in the database and it's not working can someone please tell me what i'm doing wrong?? here is my query for the SQL LOAD DATA LOCAL INFILE '/tmp/2012-8-StandardAreaCodeDatabase.csv' INTO TABLE targets FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (State,NPANXX,LATA,ZipCode,ZipCodeCount,ZipCodeFreq,NPA,NXX); but i get the following error: #2 - File 'tmp/2012-8-StandardAreaCodeDatabase.csv' not found (Errcode: 2)
  14. i have no idea what the problem was..... but i found a way around it. by the way, i think the switch case statement is working correctly. i am trying to say that if the $_SERVER['HTTP_USER_AGENT'] contains any of the following: ipad, iphone, android, ipod, webos then return is mobile. so that i can re-direct the user to a mobile compatible website. Thanks for your help
