ok heres the thing I want to make a function that validates a string thats sent to it here is what i have after fiddling.

$input=$_GET['input'];

function validate($make) {

if (eregi('(^[a-zA-Z0-9.'])|([:punct:])$',$make)) {

print "no error found";

} else {

print "error found";

}
}

validate($input);



and yet i get stupid error messages . If anyone can type out the regular expression that !!!!

ONLY ALLOWS any letter or number or any punct marks and any space !!!!!

This is to stop stupid ascii characters etc

if you could message me when you reply thanks

certain characters are 'control characters' in regex, including the full stop. to literally mean a full stop, you need to escape it with a backslash. also, you have a single quote (') between your outer single quotes. (i'm not a regex expert so someone may need to elaborate on this):

[code]
"^[a-zA-Z0-9\.\'])|([:punct:])$"
[/code]
