Download the PHP package sandromiguel/verum-php without Composer

On this page you can find all versions of the php package sandromiguel/verum-php. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

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?

Getting Started

Installation

Install Verum PHP with Composer

Usage

Simple usage example

Validate a simple registration form (name, email and age)

Valid form example

Input:

Output:

Invalid form example

Input:

Output:

Use RuleEnum class

You can use the RuleEnum class to access all rule names.

Specify the fields label (naming inputs)

Output:

Specify field labels for each language

Output (pt-pt):

Specify the messages language

You can use some built-in translations:

Specify the messages language using the LangEnum class

Specify a custom error message

Output example:

Specify a custom error message with placeholders

Output example:

Specify a custom error message for fields with and without a label

Output - Field with label:

Output - Field without label:

Specify multiple custom error messages at once

Specify multiple custom error messages at once for fields with and without a label

Handling Multi-Name Fields

With Verum PHP, you can handle multi-name fields more effectively. These are fields that include language identifiers or other variations in their names. For example, if you have fields like title.en, title.pt, description.en, and description.pt, you can specify rules for them using wildcards or by targeting specific fields.

Using Wildcards to Apply Rules to All Variants

You can define rules for all variants of a field using the * wildcard. For example:

Output example:

Validating Specific Variants

If you only want to validate a specific variant of a field, you can target it directly. For example, to validate only the English title and make titles in other languages optional:

Output example:

This allows you to apply rules more precisely, ensuring flexibility in how multi-name fields are handled based on your application's needs.

Custom validations

You can use your custom validations and inject the error message.
