PHP-Validator

This package provides tools to validate values.

Installation

composer require mirkorap/php-validator

Constraint

All values are validated with the usage of constraints. Below some examples of constraints that you can use:

BlankConstraint

Validates that a value is blank.

NotBlankConstraint

Validates that a value is not blank.

NullConstraint

Validates that a value is null.

NotNullConstraint

Validates that a value is not null.

IsTrueConstraint

Validates that a value is true.

IsFalseConstraint

Validates that a value is false.

TypeConstraint

Validates that a value is of a specific data type. You can choose among these types:

  1. string
  2. int
  3. float
  4. bool
  5. array
  6. object

EmailConstraint

Validates that a value is a valid email address.

LengthConstraint

Validates that a given string length is between some minimum and maximum value.

UrlConstraint

Validates that a given value is a valid url.

RegexConstraint

Validates that a given value matches a regular expression.

IpConstraint

Validates that a given value is a valid ip.

RangeConstraint

Validates that a given number is between some minimum and maximum number.

EqualToConstraint

Validates that a given value is equal to another value.

NotEqualToConstraint

Validates that a given value is not equal to another value.

IdenticalToConstraint

Validates that a given value is identical to another value.

NotIdenticalToConstraint

Validates that a given value is not identical to another value.

LessThanConstraint

Validates that a given value is less than to another value.

LessThanOrEqualConstraint

Validates that a given value is less than or equal to another value.

GreaterThanConstraint

Validates that a given value is greater than another value.

GreaterThanOrEqualConstraint

Validates that a given value is grater than or equal to another value.

DateConstraint

Validates that a given value is a valid date.

DatetimeConstraint

Validates that a given value is a valid datetime.

ChoiceConstraint

This constraint is used to ensure that the given value is one of a given set of valid choices. To validate the value you should provide an array or a Closure. If you set a multiple to true the input value is expected to be an array instead of a single, scalar value. The constraint will check that each value of the input array can be found in the array of valid choices.

Create custom validation form

All of these constraints implement the interface Constraint. So if you want to create your custom constraint you should implement it.

To validate a form you should create your custom form class that extends the abstract base class FormValidator. This class accepts an array of FieldValidator to validate. So each field should be an instance of FieldValidator and should contains a set of constraints. Here a basic example:

class ContactFormValidator extends FormValidator
{

    private $companyName = null;
    private $firstName = null;
    private $lastName = null;
    private $email = null;
    private $phone = null;
    private $message = null;

    /**
     * @return FieldValidator|null
     */
    public function getCompanyName()
    {
        return $this->companyName;
    }

    /**
     * @param string $companyName
     */
    public function setCompanyName($companyName)
    {
        $constraints = array(
            new LengthConstraint(255),
        );

        $this->companyName = new FieldValidator('companyName', 'Company Name', $companyName, $constraints);
    }

    /**
     * @return FieldValidator|null
     */
    public function getFirstName()
    {
        return $this->firstName;
    }

    /**
     * @param string $firstName
     */
    public function setFirstName($firstName)
    {
        $constraints = array(
            new NotBlankConstraint(),
            new LengthConstraint(255),
        );

        $this->firstName = new FieldValidator('firstName', 'First name', $firstName, $constraints);
    }

    /**
     * @return FieldValidator|null
     */
    public function getLastName()
    {
        return $this->lastName;
    }

    /**
     * @param string $lastName
     */
    public function setLastName($lastName)
    {
        $constraints = array(
            new NotBlankConstraint(),
            new LengthConstraint(255),
        );

        $this->lastName = new FieldValidator('lastName', 'Last name', $lastName, $constraints);
    }

    /**
     * @return FieldValidator|null
     */
    public function getEmail()
    {
        return $this->email;
    }

    /**
     * @param string $email
     */
    public function setEmail($email)
    {
        $constraints = array(
            new NotBlankConstraint(),
            new LengthConstraint(255),
        );

        $this->email = new FieldValidator('email', 'Email', $email, $constraints);
    }

    /**
     * @return FieldValidator|null
     */
    public function getPhone()
    {
        return $this->phone;
    }

    /**
     * @param string $phone
     */
    public function setPhone($phone)
    {
        $constraints = array(
            new NotBlankConstraint(),
            new LengthConstraint(100),
        );

        $this->phone = new FieldValidator('phone', 'Phone', $phone, $constraints);
    }

    /**
     * @return FieldValidator|null
     */
    public function getMessage()
    {
        return $this->message;
    }

    /**
     * @param string $message
     */
    public function setMessage($message)
    {
        $constraints = array(
            new NotBlankConstraint(),
            new LengthConstraint(500),
        );

        $this->message = new FieldValidator('message', 'Message', $message, $constraints);
    }

    public function buildForm()
    {
        $fields = array(
            $this->getCompanyName(),
            $this->getFirstName(),
            $this->getLastName(),
            $this->getEmail(),
            $this->getPhone(),
            $this->getMessage(),
        );

        $this->setFields($fields);
    }
