PHP-Validator
=============

[](#php-validator)

This package provides tools to validate values.

Installation
============

[](#installation)

`composer require mirkorap/php-validator`

Constraint
==========

[](#constraint)

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

BlankConstraint
---------------

[](#blankconstraint)

Validates that a value is blank.

NotBlankConstraint
------------------

[](#notblankconstraint)

Validates that a value is not blank.

NullConstraint
--------------

[](#nullconstraint)

Validates that a value is null.

NotNullConstraint
-----------------

[](#notnullconstraint)

Validates that a value is not null.

IsTrueConstraint
----------------

[](#istrueconstraint)

Validates that a value is true.

IsFalseConstraint
-----------------

[](#isfalseconstraint)

Validates that a value is false.

TypeConstraint
--------------

[](#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
---------------

[](#emailconstraint)

Validates that a value is a valid email address.

LengthConstraint
----------------

[](#lengthconstraint)

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

UrlConstraint
-------------

[](#urlconstraint)

Validates that a given value is a valid url.

RegexConstraint
---------------

[](#regexconstraint)

Validates that a given value matches a regular expression.

IpConstraint
------------

[](#ipconstraint)

Validates that a given value is a valid ip.

RangeConstraint
---------------

[](#rangeconstraint)

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

EqualToConstraint
-----------------

[](#equaltoconstraint)

Validates that a given value is equal to another value.

NotEqualToConstraint
--------------------

[](#notequaltoconstraint)

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

IdenticalToConstraint
---------------------

[](#identicaltoconstraint)

Validates that a given value is identical to another value.

NotIdenticalToConstraint
------------------------

[](#notidenticaltoconstraint)

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

LessThanConstraint
------------------

[](#lessthanconstraint)

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

LessThanOrEqualConstraint
-------------------------

[](#lessthanorequalconstraint)

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

GreaterThanConstraint
---------------------

[](#greaterthanconstraint)

Validates that a given value is greater than another value.

GreaterThanOrEqualConstraint
----------------------------

[](#greaterthanorequalconstraint)

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

DateConstraint
--------------

[](#dateconstraint)

Validates that a given value is a valid date.

DatetimeConstraint
------------------

[](#datetimeconstraint)

Validates that a given value is a valid datetime.

ChoiceConstraint
----------------

[](#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
=============================

[](#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);
    }

}
