I was able to refactor the code and get it working $('.showBox').click(function() { $('.pop-box').hide(); var toshow = $('#box'+$(this).attr('target')); var simple = 'box'+$(this).attr('target'); $(toshow).show(500); setTimeout(function() { if (simple == 'box3') { getTweets( function(){ resizeTweetBox(); }); } },500); if (simple == 'box5') { scrollChat(); } });

Hi, i've recently been learning javascript, and i've found that sometimes code works when it shouldn't, even though it throws an error. The Problem First, i need to explain that i am using two separate onclick events here. The first acts on the class of the toggle button, hiding the other toggleable divs then loading the unique one by id. the second onclick event fires specifically on the id to load the twitter feed. the problem is that the twitter feed finishes loading before the show() animation completes on the div, making the feed render at about half the size of the div, when its suppose to be 100% minus padding. We all know that loading a twitter feed can add unnecessary lag to a page, so i created a way to load it dynamically when the feed is slidetoggled onto the screen, like so: The Solution: function getTweets() { !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https'; if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js"; fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); } The side effect Now that i've loaded the twitter feed in this method, due to animations(a timer set on the show() method that makes the box appear to "grow", the twitter feed renders at half the size of the div, because the code is called for the twitter feed before the animation has completed. The Nitty Gritty Hack to make it work At first i thought i had solved the problem with this, but really i'm just preloading the twitter box, which means all of my work was for naught: getTweets().finish( function() { resizeTweetbox();//this throws an error but still works }); here's the resizeTweetbox() function for reference: function resizeTweetBox() { $("#twitter-widget-0").css("width","100%"); } I'm wondering if there is a better way i can do this. its one of those weird situations where i can't just add the function to the onclick function of the class, because its unique to the twitter feed's div. if you need to take a look my site is located at https://openex.info Thanks for your time.

well, i converted it all to the stream functions as you suggested, still no magic. finally get a response in the debug console here is the new code including all functions. it was hard to find replacements for all the socket functions, and i'm sure that i made a billion errors: // //php websocket server with tls // require_once __DIR__ .

I am in development stages of a website. this website is primarily in php. today, i decided i reached a point in development where it was time to move everything to TLS, and not suprisingly the websocket connection is being refused and i'm not sure why.

Now, i am at a total loss as to what i should try next, and there is quiet a shortage of information on this subject related to php atleast. Some other information to note: chat messages are posted via ajax to a file, sendmsg.php that also must establish a connection to this socket server and broadcast the posted message. likewise, a cronjob runs to get new alert messages and market price statistics and connects and broadcasts the information to the server in basically the same way as sendmsg.php does. Any questions are welcome, and any advice is appreciated. i may drop some btc to anyone who is able to help me fix this and move on to the next challenge thanks, Garrett

oh, so array rand only selects the key. that's counter intuitive imo. thanks requinix

the point was there is no reason to set an extra session for an admin, let alone rely on this for authentication.

There's an error in your sql query, so $query = false because there was an error. also i think you should use post instead of get. also you are using insecure method of communication with the database. code is wide open to sql injection. my suggestion would be to read up on mysqli or pdo and learn to use them. they are a bit more difficult to get comfortable with but alot better. I myself prefer mysqli but most people use PDO

Looks like i posted this in the wrong forum. My apologies to the mods, my mistake.

I'm not sure why but i'm having problem with array rand. I made the following script to test out a real time price update over websockets, to see how it looks visually when the prices are updating and debug/fine tune the client side of the price updates. so i decided i'd use array rand to select a value at random and insert it into the two test markets last_price field. the problem is, for some reason it is inserting the numeric key instead of the value. this is the first time i've used array rand, and i was wondering if someone could explain to me what i did wrong here. thanks require_once __DIR__ . '/models/config.php'; for($i = 0; $i < 20; $i++) { $prices = array('0.00321252','0.00223252','0.00121252','0.00301272','0.00091252','0.00001252','0.00005252','0.00007252'); $price1 = array_rand($prices); $price2 = array_rand($prices); $coin1 = 'TST-BTC'; $coin2 = 'TST-LTC'; global $mysqli; $stmt = $mysqli->prepare("UPDATE uc_market_data SET last_price = ? WHERE pair = ?"); $stmt->bind_param('ss',$price1,$coin1); $stmt->execute(); $stmt->close(); $stmt = $mysqli->prepare("UPDATE uc_market_data SET last_price = ? WHERE pair = ?"); $stmt->bind_param('ss',$price2,$coin2); $stmt->execute(); $stmt->close(); sleep(1); }

I'm not sure if i'm allowed to post a link to the devshed forums, but here's a pretty authorative post on the subject from Jacques. This should give you a "crash course" look at the subject of sessions in php: http://forums.devshed.com/php-faqs-stickies-167/php-sessions-secure-953373.html

I agree with Jacques. get the info from the db, don't rely on the session for authentication.

I've heard alot of people say they wouldnt use it in production, but i don't see why personally. once you get redis setup to handle sessions(requires a hack because session_save_handler is broken) that's half the battle. there are some little bizarre quirks to hhvm, and some corners have been cut, but i feel very excited about the future of php. the competition should make both engines much better.

Let's have a show of hands, who is using HHVM as a replacement to PHP? IMO, the zend engine is dead, HHVM is the new hotness. Oh, it blows Node out of the water in benchmarks too.
