standard Form Validation for textareas - dbrooke - 10-28-2016
Hello, what do you all use for set_rules for a textarea:
I have so far:
PHP Code:
$this->form_validation->set_rules('f_why', 'Why or why not?', array('trim','max_length[400]', array('customAlpha','customAlpha')));
However, I'm thinking this won't work, or I'll have to edit my customAlpha function to get it to work right with carriage returns and such.
Thanks,
Donovan

This is what I have come up with.. seems to work:
PHP Code:
if ( ! function_exists('customAlpha')) {
function customAlpha($str)
{
if (!preg_match('/^[a-zA-Z0-9 .,\-\']*$/m', $str)) {
return FALSE;
} else {
return TRUE;
}
}
}
