ereg searching for newline not acting properly

[msaspence]

I'm having a problem with the ereg function to verify a user submitted variable

 

the situation is that the user is submitting a textarea post variable

there are a number of allowed characters

there are more in the actual application but i have removed to demonstrate the problem as removing them makes no difference

the php code is as follows

 

$message=$_POST['textarea1'];

if (ereg("^[A-Za-z0-9\n]*$",$message)) {

$textValid=TRUE;

} else {

echo "error";

}

 

but it seems to act like

 

$message=$_POST['textarea1'];

if (ereg("^[A-Za-z0-9]*$",$message)) {

$textValid=TRUE;

} else {

echo "error";

}

You need to escape the backslash in your regular expression syntax....

 

^[A-Za-z0-9\\n]*$
