to is not defined
[Break on this error] setTimeout('updateChat(from, to)', 1);
I'm getting this error... I'm using Firebug to test and this comes up
in the Console.
The error corresponds to line 71 of chat.js and
the whole function that wraps this line is:
function updateChat(from, to) {
$.ajax({
type: "POST",
url: "process.php",
data: {
'function': 'getFromDB',
'from': from,
'to': to
},
dataType: "json",
cache: false,
success: function(data) {
if (data.text != null) {
for (var i = 0; i < data.text.length; i++) {
$('#chat-box').append($("<p>"+ data.text[i] +"</p>"));
}
document.getElementById('chat-box').scrollTop = document.getElementById('chat-box').scrollHeight;
}
instanse = false;
state = data.state;
setTimeout('updateChat(from, to)', 1); // gives error
},
});
}
This links to process.php with function call getFromDB and
the code for that is:
case ('getFromDB'):
// get
the sender and receiver user IDs from their user names
$from = mysql_real_escape_string($_POST['from']);
$query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$from' LIMIT 1";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_assoc($result);
$fromID = $row['user_id'];
$to = mysql_real_escape_string($_POST['to']);
$query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$to' LIMIT 1";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_assoc($result);
$toID = $row['user_id'];
$query = "SELECT * FROM `Messages` WHERE `from_id` = '$fromID' AND `to_id` = '$toID' LIMIT 1";
$result = mysql_query($query);
while($row = mysql_fetch_assoc($result)) {
$text[] = $line = $row['message'];
$log['text'] = $text;
}
break;
So I'm confused with
the line that is giving
the error. setTimeout('updateChat(from,to)',1); aren't
the parameters to updateChat
the same parameters that came into
the function? Or are they being pulled
in from somewhere else and I have to define to and from else where? Any ideas how to fix this error?
Thanks,
