Re: [PHP] Re: Simple validation problem
I wonder how that can be enough, if you consider the following form,
you can enter 45-98 and it will print ok !!
Since all http is coming as a string, I beleive the only way is to test for
invalid
characters as anything except [0-9] and the dot. (wich is my problem
because I do not really know how)
I event try with casting amount like this:
$amount = (float)($amount);
It does not work, I can still input 12r5 for exemple.
py
if( $amount 0 ){
print ok;
}else print smaller than 0: error;
if( is_float( $amount )){
print ok;
}else print not a float: error;
?
FORM ACTION=? print $PHP_SELF ? METHOD=post
INPUT TYPE=Text NAME=amount SIZE=4
INPUT TYPE=Submit NAME=Submit VALUE=Submit
/FORM

Re: [PHP] Re: Simple validation problem
Ok forget it, someone suggest to me:
if ((string)((float)$amount) == $amount (float)$amount 0) {
print ok;
}else print error;
and it works perfectly!
py
