Hello,
I am trying to make shure the amount is positive
and is a float. (format: $$$.$$)
if( $amount == "" && !is_float( $amount ) && !eregi( "^[_a-z]",
$amount ) ){
print "Error";
}
this code does not work when I the input is -25.00
What could be wrong?
py
p.s. I read what I could on regular expression, but obviously still learning...
