check a variable

[donny750]

hi,

I've script where a person take a values and i will to check if the value contain no spaces, no special caracter ( "';,:*)...).
I must have juste number and letter for example
SJsjs12 : good
12ssaff : good
dds14'"12 : not good

i'v make this

if ($var =~ m/^\w+\d+/){
 
 
print $var."good value\n";
}

but when i run my script
if the person take d120'"44 it's run but i must not run because i've '".

Thanks

/^[A-Za-z0-9]+$/

allows A through Z, a through z, and 0 through 9. In any order, minimum of one character.
