Dari apa yang saya lihat, saya pikir while tak terbatas lingkaran adalah masalah di sini.
PHP dan Soket
Jika Anda tidak dapat menggunakan NodeJS, cobalah PHP dengan Sockets. Harus bekerja untuk ini dengan cukup baik!
Peningkatan
Anda bilang Anda mencari perbaikan. Ini dia.
Ditambah lagi, saya akan menggunakan Angular untuk mengikat data yang diambil dari server ke tampilan.
File tampilan
<html>
<head>
<title></title>
{{ HTML::script('//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js') }}
<style>
#chat {
width: 300px;
}
#input {
border: 1px solid #ccc;
width: 100%;
height: 30px;
}
#messages {
padding-top: 5px;
}
#messages > div {
background: #eee;
padding: 10px;
margin-bottom: 5px;
border-radius: 4px;
}
</style>
</head>
<body>
<div id="chat">
<input id="input" type="text" name="message" value="">
<div id="messages">
</div>
</div>
<script>
var $messagesWrapper = $('#messages');
// Append message to the wrapper,
// which holds the conversation.
var appendMessage = function(data) {
var message = document.createElement('div');
message.innerHTML = data.body;
message.dataset.created_at = data.created_at;
$messagesWrapper.append(message);
};
// Load messages from the server.
// After request is completed, queue
// another call
var updateMessages = function() {
var lastMessage = $messagesWrapper.find('> div:last-child')[0];
$.ajax({
type: "POST",
url: '{{ url('chat/refresh') }}',
data: {
from: ! lastMessage ? '' : lastMessage.dataset.created_at
},
success: function(messages) {
$.each(messages, function() {
appendMessage(this);
});
},
error: function() {
console.log('Ooops, something happened!');
},
complete: function() {
window.setTimeout(updateMessages, 2000);
},
dataType: 'json'
});
};
// Send message to server.
// Server returns this message and message
// is appended to the conversation.
var sendMessage = function(input) {
if (input.value.trim() === '') { return; }
input.disabled = true;
$.ajax({
type: "POST",
url: '{{ url('/chat') }}',
data: { message: input.value },
success: function(message) {
appendMessage(message);
},
error: function() {
alert('Ooops, something happened!');
},
complete: function() {
input.value = '';
input.disabled = false;
},
dataType: 'json'
});
};
// Send message to the servet on enter
$('#input').on('keypress', function(e) {
// Enter is pressed
if (e.charCode === 13) {
e.preventDefault();
sendMessage(this);
}
});
// Start loop which get messages from server.
updateMessages();
</script>
</body>
</html>
Rute
Route::post('chat/refresh', function() {
$from = Input::get('from', null);
if (is_null($from)) {
$messages = Message::take(10);
} else {
$messages = Message::where('created_at', '>', $from);
}
return $messages->latest()->get();
});
Route::post('chat', function() {
return Message::create(['body' => Input::get('message')]);
});
Route::get('chat', function() {
return View::make('chat');
});
Model
class Message extends Eloquent
{
protected $fillable = ['body'];
}
Saya pikir, kodenya cukup mudah... Komentar harus menjelaskan segalanya.
