We can use the rules individually to parse some data.
Parsing Methods
To parse we have two functions-
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.
use Webhkp\Pvalidate\Rules\Required;
try {
$requiredValidationResult = (new Required())->parse(null);
var_dump($requiredValidationResult->isValid());
var_dump($requiredValidationResult->getErrors());
} catch (\Exception $e) {
var_dump($e->getMessage());
var_dump($e->getCode());
var_dump($e);
}Output:
string(18) " field is Required"
int(1)
object(Webhkp\Pvalidate\Exceptions\PvalidateException)#12 (8) {
["message":protected]=>
string(18) " field is Required"
["string":"Exception":private]=>
string(0) ""
["code":protected]=>
int(1)
["file":protected]=>
string(80) "pvalidate/src/Rules/ValidationRule.php"
["line":protected]=>
int(72)
["trace":"Exception":private]=>
array(1) {
[0]=>
array(5) {
["file"]=>
string(43) "index.php"
["line"]=>
int(127)
["function"]=>
string(5) "parse"
["class"]=>
string(37) "Webhkp\Pvalidate\Rules\ValidationRule"
["type"]=>
string(2) "->"
}
}
["previous":"Exception":private]=>
NULL
["additionalData":"Webhkp\Pvalidate\Exceptions\PvalidateException":private]=>
NULL
}Regex Validation
To validate a value against a regular expression, use the Regex rule. This example validates a string that should match the regex pattern /^[A-Z0-9]{3}.*/.
use Webhkp\Pvalidate\Rules\Regex;
// Regex validation
$regexRule = new Regex('/^[A-Z0-9]{3}.*/');
$regexResult = $regexRule->safeParse('D2ab');
var_dump($regexResult->isValid());
var_dump($regexResult->getErrors());Output:
bool(false)
array(1) {
["regex"]=>
string(42) " should match the regex '/^[A-Z0-9]{3}.*/'"
}
