Maximum string variable length in contact form?

Hi,
I have a Flash contact form that sends its name, e-mail, and message variables to a PHP script. The script works fine if the message is under ~700 characters, but anything more and the script won't post the message at all. An e-mail with just the name and e-mail address will come through to my inbox (which is embarrassing as a potential client sent me a contact form e-mail about a development job ).

Is there some way to check the maximum character length for a string variable? Or to set its length to something higher?

This is my php. Thank you!!

<?

$senderName   = $_POST['userName'];
$senderEmail     = $_POST['userEmail'];
$senderMessage = $_POST['userMsg'];
$senderName   = stripslashes($senderName);
$senderMessage   = stripslashes($senderMessage); 
$senderMessage = strip_tags($senderMessage, '<p><br>');
$to = "kevin@kevinburkeportfolio.com";
$from = "email@kevinburkeportfolio.com";
$subject = "E-mail from $senderName";

$message = "<p><font size='2.5' face='Helvetica Neue, Helvetica, Sans Serif'><b>FROM:</b> $senderName
<br><br>
<b>E-MAIL:</b> <a href='mailto:$senderEmail'>$senderEmail</a>
<br><br>
<b>MESSAGE:</b> $senderMessage</p>";

$headers = "From: $from\r\n";
$headers = "MIME-Version: 1.0\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$to = "$to";
    mail($to, $subject, $message, $headers);
	
	$my_msg = "Thanks $senderName, your message has been sent.";
    print "return_msg=$my_msg"; 

exit();
?>

PHP:

 

Don't use flash
lol

Honnestly, I don't see anything wrong with the above code.
To experiment, you can create an html page with a form pointing to this script to simulate, then you can see if it works ok

I'd say the limitation could be in the flash itself. Maybe the code in flash truncates the whole message when it reaches certain length?
By default you can POST 2MB of data in PHP. So the limit should be thousands of characters.

 

It doesn't have any limitations. Try increasing memory and POST limit.

 

Thank you. How would I do that?
