[](https://travis-ci.org/justinrainbow/json-schema)
[](https://packagist.org/packages/justinrainbow/json-schema)
[](https://packagist.org/packages/justinrainbow/json-schema)
A PHP Implementation for validating `JSON` Structures against a given `Schema`.
See [json-schema](http://json-schema.org/) for more details.
## Installation
### Library
```bash
git clone https://github.com/justinrainbow/json-schema.git
```
### Composer
[Install PHP Composer](https://getcomposer.org/doc/00-intro.md)
```bash
composer require justinrainbow/json-schema
```
## Usage
```php
<?php
$data = json_decode(file_get_contents('data.json'));
// Validate
$validator = new JsonSchema\Validator;
$validator->validate($data, (object)['$ref' => 'file://' . realpath('schema.json')]);
if ($validator->isValid()) {
echo "The supplied JSON validates against the schema.\n";
} else {
echo "JSON does not validate. Violations:\n";
foreach ($validator->getErrors() as $error) {
echo sprintf("[%s] %s\n", $error['property'], $error['message']);
}
}
```
### Type coercion
If you're validating data passed to your application via HTTP, you can cast strings and booleans to
the expected types defined by your schema:
```php
<?php
use JsonSchema\SchemaStorage;
use JsonSchema\Validator;
use JsonSchema\Constraints\Factory;
use JsonSchema\Constraints\Constraint;
$request = (object)[
'processRefund'=>"true",
'refundAmount'=>"17"
];
$validator->validate(
$request, (object) [
"type"=>"object",
"properties"=>(object)[
"processRefund"=>(object)[
"type"=>"boolean"
],
"refundAmount"=>(object)[
"type"=>"number"
]
]
],
Constraint::CHECK_MODE_COERCE_TYPES
); // validates!
is_bool($request->processRefund); // true
is_int($request->refundAmount); // true
```
A shorthand method is also available:
```PHP
$validator->coerce($request, $schema);
// equivalent to $validator->validate($data, $schema, Constraint::CHECK_MODE_COERCE_TYPES);
```
### Default values
If your schema contains default values, you can have these automatically applied during validation:
```php
<?php
use JsonSchema\Validator;
use JsonSchema\Constraints\Constraint;
$request = (object)[
'refundAmount'=>17
];
$validator = new Validator();
$validator->validate(
$request,
(object)[
"type"=>"object",
"properties"=>(object)[
"processRefund"=>(object)[
"type"=>"boolean",
"default"=>true
]
]
],
Constraint::CHECK_MODE_APPLY_DEFAULTS
); //validates, and sets defaults for missing properties
is_bool($request->processRefund); // true
$request->processRefund; // true
```
### With inline references
```php
<?php
use JsonSchema\SchemaStorage;
use JsonSchema\Validator;
use JsonSchema\Constraints\Factory;
$jsonSchema = <<<'JSON'
{
"type": "object",
"properties": {
"data": {
"oneOf": [
{ "$ref": "#/definitions/integerData" },
{ "$ref": "#/definitions/stringData" }
]
}
},
"required": ["data"],
"definitions": {
"integerData" : {
"type": "integer",
"minimum" : 0
},
"stringData" : {
"type": "string"
}
}
}
JSON;
// Schema must be decoded before it can be used for validation
$jsonSchemaObject = json_decode($jsonSchema);
// The SchemaStorage can resolve references, loading additional schemas from file as needed, etc.
$schemaStorage = new SchemaStorage();
// This does two things:
// 1) Mutates $jsonSchemaObject to normalize the references (to file://mySchema#/definitions/integerData, etc)
// 2) Tells $schemaStorage that references to file://mySchema... should be resolved by looking in $jsonSchemaObject
$schemaStorage->addSchema('file://mySchema', $jsonSchemaObject);
// Provide $schemaStorage to the Validator so that references can be resolved during validation
$jsonValidator = new Validator( new Factory($schemaStorage));
// JSON must be decoded before it can be validated
$jsonToValidateObject = json_decode('{"data":123}');
// Do validation (use isValid() and getErrors() to check the result)
$jsonValidator->validate($jsonToValidateObject, $jsonSchemaObject);
```
### Configuration Options
A number of flags are available to alter the behavior of the validator. These can be passed as the
third argument to `Validator::validate()`, or can be provided as the third argument to
`Factory::__construct()` if you wish to persist them across multiple `validate()` calls.
| Flag | Description |
|------|-------------|
| `Constraint::CHECK_MODE_NORMAL` | Validate in 'normal' mode - this is the default |
| `Constraint::CHECK_MODE_TYPE_CAST` | Enable fuzzy type checking for associative arrays and objects |
| `Constraint::CHECK_MODE_COERCE_TYPES` | Convert data types to match the schema where possible |
| `Constraint::CHECK_MODE_APPLY_DEFAULTS` | Apply default values from the schema if not set |
| `Constraint::CHECK_MODE_ONLY_REQUIRED_DEFAULTS` | When applying defaults, only set values that are required |
| `Constraint::CHECK_MODE_EXCEPTIONS` | Throw an exception immediately if validation fails |
| `Constraint::CHECK_MODE_DISABLE_FORMAT` | Do not validate "format" constraints |
| `Constraint::CHECK_MODE_VALIDATE_SCHEMA` | Validate the schema as well as the provided document |
Please note that using `Constraint::CHECK_MODE_COERCE_TYPES` or `Constraint::CHECK_MODE_APPLY_DEFAULTS`
will modify your original data.
## Running the tests
```bash
composer test # run all unit tests
composer testOnly TestClass # run specific unit test class
composer testOnly TestClass::testMethod # run specific unit test method
composer style-check # check code style for errors
composer style-fix # automatically fix code style errors
```
