FAQ
Example:
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 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.
Informations about the package validation
MB Validation
Русская версия
Framework-agnostic validation library inspired by Laravel-style rules, without coupling to a framework.
Features
- String rules (
required|string|min:3) - Object and closure rules
- Localized messages (
ru/en) - Wildcard array rules (
items.*.name) - Strict handling of unknown string rules (fail-fast)
- Optional file-like validation without requiring
symfony/http-foundation
Installation
symfony/http-foundation is optional.
File-related rules work with file-like objects that expose methods such as:
getSize()getPath()orgetRealPath()guessExtension()getMimeType()
Quick Start
Factory API
Create Factory
Signature:
If MessagesInterface is not provided, factory uses DefaultMessages::create($lang).
One-shot Validation
validate() throws MB\Validation\ValidationException if validation fails.
Strict Mode
Unknown string rules throw InvalidArgumentException by default.
Use backward-compatible mode if needed:
Supported Rule Groups
- Presence / structure:
required,required_if,required_unless,required_array_keys,filled,array,list,boolean - Type:
string,numeric,integer,decimal - Size:
min,max,between,size,digits,digits_between - String:
alpha,alpha_num,alpha_dash,contains,doesnt_contain,starts_with,ends_with,doesnt_start_with,doesnt_end_with,uppercase,lowercase,ascii - Format / network:
email,url,ip,ipv4,ipv6,mac_address,hex_color,uuid,ulid,json - Date / time:
date,date_format,timezone - Set / comparison:
in,not_in,same,different,prohibited,any_of - Database:
exists,unique(requiresPresenceVerifierInterface)
Messages and Localization
Default files:
lang/en/validation.phplang/ru/validation.php
Message resolution order:
- Inline messages passed to
make()/validate() - Validator fallback custom messages
- Translator (
MessagesInterface)
Inline message example:
Validate Object Properties via Trait
Use MB\Validation\Concerns\ValidatesProperties for DTO/value object validation.
Trait behavior:
- collects initialized public/protected/private properties via reflection
- supports wildcard keys (
items.*.name,profile.tags.*) - validates with
Factory::create(lang: $this->validatorLang)
Example
Get Errors with Trait
validate() throws ValidationException:
For non-throwing flow, expose a validator helper in your class:
exists / unique and Presence Verifier
Custom Rules
Closure Rule
Class-based Rule
Implement MB\Validation\Contracts\ValidationRule and register your alias in rule registry.
