Data to php

[dimiorla]

Hey Everybody,
I would like to print the test from a textarea, The php code works but when the page is opened I get error “Undefined index: datatoprint” so the data does not come over to the php page.
Does someone have un idea?
p.s. I would like the print.php not to open is their a parameter for it?
Thanks in advance Dimi

class BulletinBoard
{
function onPrint()
{
var myData:LoadVars = new LoadVars;
myData.datatoprint = _root.postMessages.datatoprinttextarea.text;
myData.send("print.php" , null, "POST");
}
}

<?
$datatoprint = $_POST["datatoprint"];
$handle = printer_open("HP Deskjet 930c");
printer_write($handle, $datatoprint);
printer_set_option($handle, PRINTER_MODE, "raw");
printer_close($handle);
?>

Line 3 of the PHP code:

printer_write($handle, $ datatoprint); 

Should be:

printer_write($handle, $datatoprint); 

You have a space separating the '$' and the variable name (datatoprint)

Sorry type error, it's not in my print.php

Try changing the PHP file to 'GET' instead of 'POST', then try typing the name/value variable into the URL (in your browser) to see if the error comes up.

For instance:
http://www.example.com/print.php?dat...intingThisText

If it works, chances are your variables are not properly sending from Flash.

If it doesn't work, it means the problem is in your PHP code. Try removing all references to 'printing' (the last three lines). If your code is working now, that means the printer_write line is getting unexpected input (I've never used printer functions in PHP before...)

What you're doing is the 'process of elimination' to determine the true cause of the problem.

Undefined index usually means you are trying to use data which has not yet been defined, such as the POST variable you are trying to recieve. Since POST isn't as visible as GET, you may possibly not even be sending the variable.

Let me know how that goes.

Thank for the tips, they have helped a lot,
For anyone interested this works without a popup

myData.sendAndLoad("print.php", this, "POST");
