ValidatorGRIDMI 2.0.0

Simple JSON validator for PHP.

This class will allow you to check the structure of the incoming JSON data.

No dependencies, only one static class!

What types does the class work with?

TYPE	DESCRIPTION
Array	An array can be both an object and a primitive. If you want to check the structure of the array on the object template, then in properties you need to describe the object template. If you want to check each element of the array as a primitive, then you must specify the type of the primitive in the properties. You can limit the length of the array by adding an object with the name length and the properties min and max.
Object	In properties you describe the structure of the object. You can limit the length of the array by adding an object with the name length and the properties min and max. You can describe the mandatory presence of an object property. More details below.
String	Check string function - is_string(data). If you want to check the string for compliance with a regular expression, then you need to add an object pattern with the value and description properties. Value is a regular expression pattern and Description is a description of the error in case of inconsistency.
Numeric	Numeric check function - is_numeric(data). If you want to check the numeric for compliance with a regular expression, then you need to add an object pattern with the value and description properties. Value is a regular expression pattern and Description is a description of the error in case of inconsistency.
Double	Double check function - is_double(data). If you want to check the double for compliance with a regular expression, then you need to add an object pattern with the value and description properties. Value is a regular expression pattern and Description is a description of the error in case of inconsistency.
Float	Float check function - is_float(data). If you want to check the float for compliance with a regular expression, then you need to add an object pattern with the value and description properties. Value is a regular expression pattern and Description is a description of the error in case of inconsistency.
Integer	Integer check function - is_int(data). If you want to check the integer for compliance with a regular expression, then you need to add an object pattern with the value and description properties. Value is a regular expression pattern and Description is a description of the error in case of inconsistency.

Features

Each validation template must contain a property type for recursive validation.

Example schema

{
  "type": "object",
  "length": {
    "min": 0,
    "max": 10
  },
  "properties": {
    "name": {
      "type": "string",
      "pattern": {
        "value": "/^GRIDMI$/",
        "description": "Wrong field `name`!"
      }
    },
    "age": {
      "type": "integer",
      "required": true
    },
    "telephones": {
      "type": "array",
      "properties": "integer"
    },
    "friends": {
      "type": "array",
      "required": true,
      "properties": {
        "name": {
          "type": "string"
        },
        "email": {
          "type": "string"
        }
      }
    }
  }
}

Required fields

If the property in the object is not found, then the class can refer to the structure to check whether this field is appropriate. If the property required is not found, an error will be caused that the presence of the property is not described!

Result of checking

The class will return an array of errors. The levels of the array depend on whether you specified the removal of the hierarchy when calling a static method. The number of errors depends on which validation mode you have selected.

Class use

require 'ValidatorGRIDMI.php';
$errors = ValidatorGRIDMI()::onValidate(JSON_SCHEMA, JSON_DATA, BOOL:remove_hierarchy?, BOOL:strict_mode?);
echo empty($errors) ? 'No errors found!' : implode(', ', $errors);
