FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package validator

A PSR Container compatible Validator implementation.

Installation

This package provides the following constraints:

#[Count]

Checks whether the specific value as exactly given count.

#[GreaterThan]

Checks whether the specific value is greater than expected.

#[Initialized]

Checks whether the specific property of object is initialized with any value.

#[Length]

Checks whether the specific value is in specified length range.

#[LessThan]

Checks whether the specific value is less than expected.

#[Negative]

Checks whether the specific value is negative (strictly less than 0).

#[NotBlank]

Checks whether the specific value is not blank (empty array/blank string/is not initialized).

#[Positive]

Checks whether the specific value is positive (strictly greater than 0).

#[Range]

The same as Length but for int and float.

#[Regex]

Checks whether the specific value matches given regexp expression.

#[Cascade]

If your object contains other object as property which you want to validate or array|iterable of objects you can place this attribute and validator will validate this object by its own constraints or array of objects.

Usage:

Writing custom validators:

An option to pass Psr\Container\ContainerInterface to validator class

If you are using this validator inside some frameworks or in projects with di container, you can pass this container to Validator constructor. In this case when validator will instantiate constraint validators for your custom constraints, first it will check if target constraint validator exists in container. If it does not, it will try to search all dependencies of your constraint validator, if it won't find any, the exception will be thrown. Example:

Notes:

  1. When ValidatedValueInterface is passed into validator, if the property which is validated is uninitialized, then null will be passed as value. In these cases it is recommended to add NotBlank or Initialized validators with combination with your custom validators;
  2. All validators except NotBlank and Initialized do not trigger validation errors on properties which are uninitialized.
