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.

Installation

Install with composer:

Basic Usage

The check() method instructs the object that this is a new value to validate. Additional methods are chained from this. Below shows an example of the object checking a value is not empty, then checking it is a valid email address.

To fetch the errors from a validation check, use getErrors():

After validation, check if data is valid:

Check if a data has been given. Useful for checking checkboxes have been ticked:

Note: will not work for empty strings, which isNonEmpty should also be used.

This will return an array of containing the error that occured (Email address is blank). Please note that although the isEmail method was called too, because it has already gathered an error it does not record another. Remember this when ordering your methods in the chain.

It is also possible to do this in one go, and return errors:

Optional fields are when validation only occurs on that param if the param is given.

Other methods for validating

The above example shows how to validate an email address but the following methods can be used to numeric, date and time stings too. Below is the full list of validation methods available.

Other error logging

You can use the logError() method too to log a custom error:

Extend Validator

Sometimes it's useful to add your own validator methods. This can be done by extending the class, and ensuring that your new method returns the instance logs the error:

Then you can chain the method as with the built in ones:
