ActionScript 2.0 :: Limits On Sending Data With LoadVars?
Feb 21, 2008
I was wondering if anyone had found out that there is a limit to how much information can be sent with LoadVars. I guess that limit could be the number of properties of the loadVars object, or size of the properties being sent.

I've got a small problem with loadvars. I want to send data from Flash to PHP, which usually works well. But right now I need to send "larger" amounts of data around 10-20kb and loadvars doesn't work anymore.
Using loadvars to open browser-windows seems to work fine, but I want everything to happen inside of flash.
The code is:
Code:
datastring = "1, 2, 3 (...) 4998, 4999, 5000"; // long text
loadstring = 'save.php?data='+datastring;
db = new LoadVars();
[Code].....
Works fine with small text, with big text nothing happens. How to do this the right way?
Edit: Loadvars seems to work up until 4050 characters, 4051 and it doesn't send anymore. But I can't really split the query..

There seems to be a problem with Firefox 2.x sending variables to PHP scripts with the LoadVars.send/POST method.
<br>
The same problem doesn't occur in IE or Opera. <br>See this url for example to try in both FF and IE/Opera: here. <br>The source files are here g.zelenka@iinet.net.au

stop ();
function sendForm () {
my_lv = new LoadVars ();

I'm trying to create a test taking application for a system that already exists. Currently everything is done in HTML, but they need to convert the app to flash to add tricky components. So for now, everything is in HTML format and everything is created dynamically using mod_perl and a mysql database.The problem really comes in when one of the test questions has an image included with it. The image is stored in the database and with HTML was just inserted into the <HEAD> tag in raw format. The image does not actually reside anywhere on the server , just in the database.

I am using loadVars with the send method to send my contact info to a php file. This works fine but when I press the submit button the browser goes to the email.php file. How do i prevent it from opening that file in the browser window?
Heres the [AS]
lv = new LoadVars();
lv.name = name;
lv.company = company;
lv.phone = phone;
lv.email = email;
lv.message = message;
lv.send("email.php", "POST");
}

I was just wondering if it is important to include POST as a method of sending loadVars to the php file. i was using POST before and i still ecountered some problems of receiving empty mails. Since i found an example which do not use POST or REQUEST method i dont have anymore prob. I just wanted to get another opinion about that as i wanna start using server side script with flash and i know that ill be using the POST method.

I will be creating a program to use for data entry. I'll be studying zebras in kenya and I won't have the internet there as I'm recording the data. I'd like to be able to send the data I generate in flash to an external text file. I understand I need some sort of script to do that, but is this something I can run just on my machine? (I'll probably make the data into xml format).

All the examples in the text books, etc. show the LoadVars object being used with a .txt file. Can I use it with a .xml file or not? I have tried but the output panel just shows rubbish data!

I have an interactive Flash simulation that I have imported into SABA Publisher. I need for the Flash file to communicate with SABA, basically returning that the user has successfully completed the simulation. SABA is supposed to be able to receive data from Flash.

I am using the loadVars class (Flash 8) to load key/value pairs from a mySQL database through php (example &pic1=pic1.jpg&pic2=pic2.jpg&...).
The ultimate goal is to create a dynamic slideshow with a variable length, depending on how many pics were submitted by the user. Since the associative array object returned by loadVars does not share the "length" property of indexed arrays, my guess is that the values need to be converted into a new indexed array before being able to use them in the slideshow.

I'm messing around with trying to load variables from a text file and it's just not working as I'd expect. First, my text file is formatted like this
[Code]...
For example, if I do something like create a simple Dynamic Text Box on the same frame as the above code, to show the value from _level0.Test.variable1, it displays "undefined" even though the debugger indicates this variable has the value "value1" as I wish it to. (using "trace(_level0.Test.variable1)" yields no better results)
I have attemped using onLoad and onData alongside the above code, and neither one has made the situation better. I have also attempted trying to reference the variable in a few different ways, and it's just returning the same thing every time. When I was experimenting last night, I managed to get the variables to show up properly on a "trace()" but not when referenced by other things in the flash file. Regrettably, I cannot remember how I did this. Either way it didn't quite work still. Do I need to do something else to be able to reference loaded data in my project, or is there some fundamental mistake I am making? I'm usng Flash CS3 Pro, if that makes any difference. Flash Player is up to date, etc.

I'm using Flash MX (2002) and I need to get my variable values saved to a server each time my test subjects run and finish my swf/fla (PHP scripts and a .txt file on the server are being worked on, but that's a different nightmare!). I'm pretty sure I should use LoadVars, NOT SharedObject for this data capture right?. The data must not be overwritten each time over the course of a few months of data collection. The 3 variables are: username (name of the user), counter (this keeps track of which version the user chooses from the start menu), numcorrect (keeps track of the number of times the <right> arrow key is pressed).
2 main problems: I don't know where to put in the LoadVars obj (in the AS code of "finaldisplay" frame?) AND I don't know how to build/format the LoadVars object to capture the data in the 3 variables I listed above. I've got several Flash books and have done online tutorials, so for something so simple (3 lousy variables!)...why is my life so miserable? Here's my zipped .fla.

I am having problems with loadVars over https. What I am trying to do is sending credit card information from a flash store to a PHP-script on a server over https, and the PHP-script should return a reply. (So I am using the LoadVars sendAndLoad command). The problem is that the reply I get from the script is empty. If I try the same over http, it works fine.

A combobox (created with the returned data) is created on frame 61. When a selection is chosen in the combobox I need to add the value returned from the combobox to the variable catvar, add this variable to the LoadVars object and run the script again. It seems to set c.catvar initially but when I use the 'sendAndLoad command the second time c.catvar isn't included. Is it possible to add variables to a LoadVars object created
on frame 1 from frame 61?

The problem is that it executes #Second before #First, which means that the object is not fullly loaded but the code continues nonetheless. Is there a way handle this? I have tried using a while loop, but this is ugly and makes flash crash. Is there any decent way to handle this, does it have to do with better code structure/program flow or is there a technical way to make it wait? Also note: This code is executed on the server side, which means there are no frames involved.
UPDATE:When projects get bigger, this gets very ugly, especially when you are retrieving mulitple things from a server, you have to use very deep nesting, you have to keep repeating the same code, example for buying a serial:
a.onload() {
if(moneyAmount > 10){
b.onload(pay) {

For the life of me, I've tried everything: I've researched LoadVars on Adobe forum, used David Powers' books, googled 'flash to php', LoadVars, etc. and tried sendAndLoad, send, and using $_POST, $_GET, $_REQUEST. $HTTP_POSTVARS but I keep getting this same error.
I have a Unix server running Apache/PHP 4 - LoadVars worked to load name-value pairs into an array -see thread)
My goal with this simple app is to prototype being able to pass a variable from flash to a variable in php.

I am using FMS 4.5 and have a simple application which I want to use to send two strings to a php file. But I get a compilation error whenever I try to assign any value to these objects:
Here is main.asc:
<code>
var variables = new LoadVars();
variables.username = "uname";
variables.send(http://url.abc.com/test.php,POST)
</code>
I can't compile with the second line. FMS just says: Sending error message: Compilation error

This code is being run from a frameset in IE8. When the new window is opened, the form data is not being recognized. It appears that the http header, "content-type: application/x-www-form-urlencoded", is not being passed into IE and this is causing the post data not to be processed. The data is there, IE is just doing nothing with it.
This code works fine in FF and Chrome, and in fact the correct headers are passed in FF and Chrome.
NOTE: The new page is on a different site, but i don't know why that would cause a problem with a POST and not a GET.
Flash code:
varSender = new LoadVars();
varSender.title = _parent.tCourseTitle;
varSender.notes = input_txt.text;
varSender.send("http://example.com/notes/print.cfm", "_blank", "POST");
I have tried adding the header to the send request, but that has no effect at all. The contenttype header is still missing and it still works everywhere but IE.
My current work around is to use a GET instead of a post, but that's ugly and it limits us in the size of data we can pass but for now at least it works.

I am working to send data from as3 to php and I am having a little trouble with it. I am new to both AS3 and php but at this point I think I am doing fine.The project is simple it just takes two values from as3 and send its to php. But apparently I am not able to send variables from as3 to php. Here is the code(its very simple code):[code]I am sure the insert.php is working as I hardcoded the values in insert.php and it inserts the rows. So, I am assuming that there is some problem with sending the data from as3 to php.
