We can build a validator step by step by adding one rule at a time, and then finally parse data.
Examples
Here are a few examples of using the rules individually to parse and validate data-
Required Validation
To validate if a field is required, use the Required rule. This example demonstrates how to validate a null value, which should fail the validation.
<?php
require_once "vendor/autoload.php";
use Webhkp\Pvalidate\ValidationBuilder;
$validation = ValidationBuilder::required()->gt(11)->gte(200)->range(min: 1, max: 1000)->safeParse(11);
var_dump($validation->isValid());
var_dump($validation->getErrors());
//var_dump($validation->getMessages());
Output:
bool(false)
array(2) {
["gt"]=>
array(3) {
["value"]=>
int(11)
["valid"]=>
bool(false)
["errors"]=>
array(1) {
["min"]=>
string(26) " should be larger than 11"
}
}
["gte"]=>
array(3) {
["value"]=>
int(11)
["valid"]=>
bool(false)
["errors"]=>
array(1) {
["min"]=>
string(38) " should be larger than or equal to 200"
}
}
}
