LoadVars with PHP
I am new to flash (Still on the 30 day trial of CS3) but I am not as new to PHP. I heard about this loadvars thing, and googled it, and it said with some code I could load the variables from a PHP file. I am trying that out, so here is my code.


//test loadvars function

testVarPhp = new LoadVars();

//make testVarText read the same as testVar.testvar
testVarText.text = testVarPhp.testvar;

I checked about 4000 times all the spellings of files and variables and the name of the text field and stuff. The text field displays the word "undefined" and I don't know what that means. When I checked the script for errors, it said it had none, so I have no idea what is going on, please help.

try this. I will test if your vars are coming thru and you can track down the problem a little easier.

var testVarPhp:LoadVars = new LoadVars();
testVarPhp.onLoad = function(success:Boolean) {
    if (success) {
        testVarText.text = testVarPhp.testvar;
    } else {
        trace("Error loading/parsing LoadVars.");

Alright thanks. Hopefully that will do it, but out of curiousity, why the colons? Are those for defining the type of variable it is or something?

I still get the same result, and I really have no clue what the problem is.

the colons tell the function what type of variable to expect, like boleen, string, init.

what does the trace statement say?

Sounds like flash isn't finding your php page or the data is not in correct format. Can you pull up your php page in your browser? want is that exact url, make sure that url is correct. Then copy and paste what your php page is writing to the browser so I can see how that content is formated. It should be writing out something in this format.

Oh, I found out why I messed up. I wasn't even really clear on how to use the loadvars function, thanks. And yeah, the url is correct. Ok, sry, I am a noob at flash. Thanks. Hopefully this works

Only one more thing, for some reason, I have the code written out on my php page as:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Test Loadvars, actionscript function</title>

    echo "&testvar=Testing";

And for some reason it is displaying the <Body> tag which is kind of wierd.

since all you are doing is retrieving information via script and this page will run in the background you do not need the html headers.

all you need on your php code to process whatever data and then write it to the page.
<?php echo "&testvar=Testing"; ?>
