Examples
Just a few quick examples. Let's define a set of filters for a person record.
// let's pretend this came from $_POST $input = [ 'name' => 'john smith ', 'birthday' => '1990-01-01__', 'bio' => "Mistakenly written on Windows\r\nThat's a problem. ", 'friends' => 'Jane' ]; $registry = new \Caridea\Filter\Registry(); // you can register your own filters if you choose $b = $registry->builder(); $b->always('name')->then('trim')->then('titlecase'); // always() will run chain even if missing from input $b->field('birthday')->then('regex', '/[^0-9-]/', ''); $b->field('bio')->then('trim')->then('nl'); // convert to UNIX newlines $b->always('species')->then('default', 'Homo sapiens'); $b->field('friends')->then('array')->each('trim'); // each() will run the filter on every element // by default, all fields you don't specify are dropped. // but! otherwise() can specify a fallback chain for any non-declared fields. // $b->otherwise('trim')->then('default', null); $filter = $b->build(); $output = $filter($input); var_dump($output);
array(5) {
'name' =>
string(10) "John Smith"
'birthday' =>
string(10) "1990-01-01"
'bio' =>
string(47) "Mistakenly written on Windows
That's a problem."
'species' =>
string(12) "Homo sapiens"
'friends' =>
array(1) {
[0] =>
string(4) "Jane"
}
}
You can also supply one or more Reducer
s which are intended to combine and rewrite multiple values at once.
// let's pretend this came from $_POST $input = [ 'username' => ' doublecompile ', 'id-0' => '1', 'id-5' => '4', 'id-1' => '9' ]; $registry = new \Caridea\Filter\Registry(); $b = $registry->builder(); $b->always('username')->then('trim'); $b->reducer(Combiners::appender('ids', 'id-')); $filter = $b->build(); $output = $filter($input); var_dump($output);
array(2) {
'username' =>
string(13) "doublecompile"
'ids' =>
array(3) {
[0] =>
string(1) "1"
[1] =>
string(1) "4"
[2] =>
string(1) "9"
}
}
The Filter
class itself is a Reducer
.
