Im setting up a form:
<?php
$item = new \CoreExt\Form\Element\Numeric(self::NAME_KILOMETER_VALUE);
$item->addFilter('naturalnumber');in services.php, I do register this:
<?php
$filter = new \Phalcon\Filter();
$filter->add('naturalnumber', function ($value) {
return abs((int)$value);
});still, when I validate the form:
sanitize filter 'naturalnumber' is not supported
You are not returning filter instance from your IoC?
$di->setShared('filter', function () {
class IPv4Filter //TODO make pull request to Phalcon / Zephir code base with this filter
{
function filter($addr = null)
{
//Validates value as IP address, only IPv4 and not from private or reserved ranges.
return filter_var($addr, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE);
}
}
$filter = new \Phalcon\Filter();
$filter->add('ipv4', new IPv4Filter());
return $filter;
});Usage example:
if (!$this->filter->sanitize($ipAddressFromClient, 'ipv4')) throw new Error('Invalid client IPv4 address supplied.', 403);even I return this, still not work
You need to use services syntax ($di).
So, your example like this won't work UNLESS you use it in a local scope.
<?php
$filter = new \Phalcon\Filter();
$filter->add('naturalnumber', function ($value) {
return abs((int)$value);
});Check official documentation or use example I provided for setShared service registration.
