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.

Installation
Installation method is via composer and its packagist package validat/validat.
How to use
Method
All functions are static so you could call them anywhere, anytime. If you wanna check if your array is associative Vali::Assoc( array( 'a' => 'b' ) ), if you want to assign name to validation for clearer errors Vali::Assoc( array( 'a' => 'b' ), 'My assoc array' ), if you wanna check if it's not associative array Vali::Assoc( array( 'a' => 'b' ), 'My assoc array', true ) or just !Vali::Assoc( array( 'a' => 'b' ), 'My assoc array' ). All function and their usage is explained below but you get the idea.
Schema
Schema is predefined structure of data you want to validate. It helps if you recive multiple, nested variables in your API and don't wanna create hundreds of ifs to validate them.
Structure is divided into set and free variables. The set is validated first then all left values with free. You can assign them names (for geting clearer errors) and types. Available types :
- int
- decimal
- array
- bool (boolean)
- date
- string (will return false if string is empty)
- string_empty (will return true if string is empty)
- object
- null
- js (will return true if string contains javascript)
- php (will return true if string contains php)
- json (checks if string is available to be read as JSON)
It's possible to check if data isn't something. Just add ! before type and it will revert it. Example: [..] 'desc' => ['name' => 'Description', 'types' => ['!js','!php']] [..]. Now it will return false if desc contains any js or php.
If you don't want to use string_empty because all your strings can be empty just change the default setting Vali::$_STRING_EMPTY to true. It will change the behaviour of String function to return true even if string is empty.
And finaly errors: when error occurrs (when variable isn't valid or doesn't exist) apropriate error will be saved into $_LAST_ERROR as a string. To get error you can use Vali::GetError().
Dynamic type assign
What's cool is that you can change the validated type of variable by sending diffrent data and using keyword this. The script will look out in current scope for indicated data and use it contents as types. Example :
FUNCTIONS
Legend:
$var- variable to validate$name- the name to use in error$reverse- reverse the behaviour of method
Usage
Vali::Int($var, ?string $name = null, bool $reverse = false)Vali::String($var, bool $empty = false, ?string $name = null, bool $reverse = false)Vali::Decimal($var, ?string $name = null, bool $reverse = false)Vali::Day($var, ?string $name = null, bool $reverse = false)Vali::Bool($var, ?string $name = null, bool $reverse = false)Vali::Null($var, ?string $name = null, bool $reverse = false)Vali::Array($var, ?string $name = null, bool $empty = true, bool $reverse = false)Vali::Assoc($var, ?string $name = null, bool $empty = true, bool $reverse = false)Vali::Object($var, ?string $name = null, bool $reverse = false)Vali::JS($var, ?string $name = null, bool $reverse = false)Vali::PHP($var, ?string $name = null, bool $reverse = false)Vali::JSON($var, ?string $name = null, bool $reverse = false)Vali::Mail($var, ?string $name = null, bool $reverse = false)
