I saw a site a guy did about a year ago. His dynamic text boxes were not getting info from a txt file but were in fact getting the text and data from php and asp pages. No kind of special coding in the php or asp files but were created that way for extremely easy update using an update interface form that he created.
you just need to get your PHP or ASP script to write out variables (possibly the results of a database query or reading an external file etc) to the page as a urlencoded query string (like how you would type the text if you were just typing into a textfile for flash to load)
when you use something like loadVariables to call the script that contains this flash will read back these variables into the timeline that called the loadVaraibles action.
remove all the excess html code from the file though, flash can only read the string of variables (the stuff included in the <body> of the page)
is there any reason why this needs to be ASP (or PHP for that matter) unless that information is being pulled from a database or being generated dynamically in some other way you may as well just type out the code and save it as a textfile.
again if this is the case I wouldn't load variables from the ASP file.
instead you can create an ASP page with form fields for the user to fill in to update the content. this ASP page can then write the text file (I don't know much ASP, but I assume it can do this kind of stuff, certainly things like PHP can) you can then get flash to load the textfile created by the ASP page.
I don't know ASP well, but this code does the same thing in PHP
to begin lets say your flash movie has 3 fields that need to be filled with dynamic text (flashVarName1, flashVarName2 and flashVarName3) to begin you can create an html form that can be used for whoever is updating the site (in the real world you'd proabably want to password protect this page so only people you want updating the site have access) use input fields appropriate to the content, for example textareas for fields where a lot of text is likely to be entered. here's an example
<html>
<head>
<title>update flash content</title>
</head>
<body>
<form method="post" action="writefile.php">
<p>enter text for flashVarName1 here <input type="text" name="flashVarName1" /></p>
<p>enter text for flashVarName2 here <input type="text" name="flashVarName2" /></p>
<p>enter text for flashVarName3 here <textarea name="flashVarName3"></textarea></p>
<p><input type="submit" value="update!" /></p>
</form>
</body>
</html>
when the form is submitted it gets sent to the page writefile.php which can create the textfile.
PHP Code:
<?php
function writeText() {
if (!$fp = fopen('data.txt', 'w')) { // attempt to open a file, data.txt for writing if it doesn't exist try to create it
return 'fail'; // it hasn't worked
}
// create a variable containing a urlencoded query string of the variables to be loaded into flash
$content = '&flashVarName1=' . urlencode($_POST['flashVarName1']);
$content .= '&flashVarName2=' . urlencode($_POST['flashVarName2']);
$content .= '&flashVarName3=' . urlencode($_POST['flashVarName3']) . '&';
fwrite($fp, $content); // write the content to the file (overwrites existing content)
fclose($fp); // close the file
return 'okay';
}
$result = writeText();
if ($result == 'okay') {
echo "thanks for updating the site content";
} else {
echo "there was an error, please <a href=\"javascript:history.go(-1);\">click here to go back</a>";
}
?>
in flash you can now load the file data.txt to get at the content
You can use the loadvars object to load the text from a file and display it in your movie,
for example the following would load file named filename.txt (containing a variable named myVariable) and display this variable in a textfield with the instance name myText,
Code:
var lv = new LoadVars();
lv.onLoad = function(ok) {
if (ok) {
myText.text = this.myVariable;
}
};
lv.load("filename.txt");
