flash ignoring "\n" when loaded from LoadVars

[JoshuaJonah]

ok, Flash is making mad again. If i do something simple like this:


var sometext:String = "blahblahblahblah \n blahblahblah";
some_textbox.html = true;
some_textbox.htmlText = sometext;
It work's great, says:

blahblahblahblah
blahblahblah

But if i load the text via LoadVars, it ignores my "\n"s:


var dbtext:LoadVars = new LoadVars();
dbtext.sendAndLoad("somephpfile.php", dbtext)
dbtext.onLoad = function(){
var sometext:String = dbtext.loadedtext;
some_textbox.html = true;
some_textbox.htmlText = sometext;
}
duzn't work, says this:

blahblahblahblah \n blahblahblah

What is the code in somephpfile.php?

[JoshuaJonah]

for the sake of this example(which is fake by the way), the actual file im working with is huge.


<?php
$blah = "blahblahblahblah \n blahblahblah"
echo "loadedtext=".$blah
?>

[JoshuaJonah]

well, i guess the php isn't really that big. Heres the real file(sans password:)):

<?php
require_once('classes/database.php');
$hostname = 'localhost';
$username = 'news';
$password = 'xxxxx';
$db = new Database($hostname, $username, $password, 'jj');
$sql = 'select * from news';
$result = $db->query($sql);
$total = $result->num_rows;
$count = 1;
while ($row = $result->fetch_assoc()) {
$thenews .= '&date'.$count. '=' .$row['date'].'&type'.$count. '=' .$row['type'].'&body'.$count. '=' .$row['body'].'&link'.$count. '=' .$row['link'];
$count++;
}
$truecount = $count-1;
echo 'total='.$truecount.$thenews;
$db->close();
?>

try this:


<?php
$blah = "blahblahblahblah \\n blahblahblah"
echo "loadedtext=".$blah
?>


I think you need the double backslash in there so flash still sees it.

-bigmtnskier :)

[JoshuaJonah]

ok, but flash is tracing the backslash, it's also putting it in the textfield

[JoshuaJonah]

ok, if i send it:

<?php
$blah = "blahblahblahblah \n blahblahblah"
echo "loadedtext=".$blah
?>
It goes to next line
but if i put:

<?php
$blah = "blahblahblahblah \\n blahblahblah"
echo "loadedtext=".$blah
?>
It shows "blahblahblahblah \n blahblahblah" in the text field.

Why is is passing "\n"s as "\\n" when i'm pulling it from MySQL? Ok i'm gonna try using stripslashes in php.

[JoshuaJonah]

ok, when i strip them it strips ALL the slashes so the texfield is now displaying: "blahblahblahblah n blahblahblah"

[JoshuaJonah]

you know how to make a php function that will only strip the first slash if two are found in a row?

Edit: ok i made a function like this:

function fix($text) {
$text = str_replace("\\", "\", $text);
return $string;
}
edit again: why is this not working, it's like it doesn't like the slashes in the function

[JoshuaJonah]

yay!.... i just changed it to:

function fix($text) {
$text = str_replace("\\n", "\n", $text);
return $string;
}

[bigmtnskier]

Glad you got it fixed :)

[Immulsifier]

Could have used \r instead of \n and flash would have picked this up as a new line.

[JoshuaJonah]

umm.... so does \n .....?

[Immulsifier]

Yes but you wouldnt have had to run it thought that function to strip off slashes.

[JoshuaJonah]

But the file would still be littered with \n's beause of the textfield i was entering the text with.

I ended up just stripping everything then using php to automatically insert \n's using a wordwrap script.
