Allowing a DASH to pass as numeric

[moishy]

I want that certain fields in my form must be numeric.

I'm using the "if_numeric " code for that.

But if I submit a form with a phone number that contanes a dash, It will not be accepted.

Example:

Phone: 1516-678-9010

Will not be accepted.

However, only such a number will be accepted:

Phone: 15166789010


So, how to I add a "DASH" to the "Whitelist" ?

The following is a little snippet that, after removing the blanks and the dashes, checks if the input field contains 9 to 14 digits only. You could use that to check your telephone no, allowing people to have blanks or dashes inside.
[php]
$tests = array( "314-5565-400",
"800-555-4400",
"(314)555-4000",
"3146784000 ",
"555",
"5342 875 6478",
"1234-123-12345"
);
foreach ($tests as $test) {
if (preg_match('^\ d{9,14}$^', str_replace(arr ay(" ","-"), "", $test))) {
echo "Matched on $test<br />";
}
else {
echo "Failed match on $test<br />";
}
}
?>
[/php]

The ascii character of '-' has to be taken and check the ascii value entered using Charcodeat function.
