Hi,

I am trying to use the code below to only allow through numeric or a + sign or whitespace.

So it would let through this +0989 and 9879

but would not let through +989jkhj or kjhkj9089

I have this, now i know ctype_punt isn’t right but im not sure

[code=php]
$val = ‘9890 +’;
if (!ctype_digit(trim($val)) && !ctype_punct(trim($val))) {
echo ‘No’;
} else {
echo ‘Yes’;
}
[/code]

Thanks

@ScleppelOct 24.2005 — You could use preg_match.
[code=php]$val = '9890 +';

if (!preg_match('#^[0-9+ ]+$#',trim($val)))
{
echo 'No';
}
else
{
echo 'Yes';
}[/code]
