hi anybody knows how to validate form field for numbers, text etc... just one line example will do

Code: [Select]

if (empty($_REQUEST['co_telephone']))
$app->error('Please enter Telephone');
// i have validated like this but i only want to accept numbers 9 characters only, it only checks if it is blank or not

any help will be most welcome...

[jscix]

if (empty($_REQUEST['co_telephone']) || !(is_numeric($_REQUEST['co_telephone'])) || strlen($_REQUEST['co_telephone']) !== 9)
    {
           $app->error('Please enter Telephone');
    }
