# Getting started
GUMP is a standalone PHP data validation and filtering class that makes validating any data easy and painless without the reliance on a framework. GUMP is open-source since 2013.
Supports wide range of PHP versions (**php7.1** to **php8.3**) and **ZERO dependencies**!

#### Install with composer
```
composer require wixel/gump
```
### Short format example for validations
```php
$is_valid = GUMP::is_valid(array_merge($_POST, $_FILES), [
'username' => 'required|alpha_numeric',
'password' => 'required|between_len,4;100',
'avatar' => 'required_file|extension,png;jpg',
'tags' => 'required|alpha_numeric', // ['value1', 'value3']
'person.name' => 'required', // ['person' => ['name' => 'value']]
'persons.*.age' => 'required' // ['persons' => [
// ['name' => 'value1', 'age' => 20],
// ['name' => 'value2']
// ]]
]);
// 1st array is rules definition, 2nd is field-rule specific error messages (optional)
$is_valid = GUMP::is_valid(array_merge($_POST, $_FILES), [
'username' => ['required', 'alpha_numeric'],
'password' => ['required', 'between_len' => [6, 100]],
'avatar' => ['required_file', 'extension' => ['png', 'jpg']]
], [
'username' => ['required' => 'Fill the Username field please.'],
'password' => ['between_len' => '{field} must be between {param[0]} and {param[1]} characters.'],
'avatar' => ['extension' => 'Valid extensions for avatar are: {param}'] // "png, jpg"
]);
if ($is_valid === true) {
// continue
} else {
var_dump($is_valid); // array of error messages
}
```
### Short format example for filtering
```php
$filtered = GUMP::filter_input([
'field' => ' text ',
'other_field' => 'Cool Title'
], [
'field' => ['trim', 'upper_case'],
'other_field' => 'slug'
]);
var_dump($filtered['field']); // result: "TEXT"
var_dump($filtered['other_field']); // result: "cool-title"
```
### Long format example
```php
$gump = new GUMP();
// set validation rules
$gump->validation_rules([
'username' => 'required|alpha_numeric|max_len,100|min_len,6',
'password' => 'required|max_len,100|min_len,6',
'email' => 'required|valid_email',
'gender' => 'required|exact_len,1|contains,m;f',
'credit_card' => 'required|valid_cc'
]);
// set field-rule specific error messages
$gump->set_fields_error_messages([
'username' => ['required' => 'Fill the Username field please, its required.'],
'credit_card' => ['extension' => 'Please enter a valid credit card.']
]);
// set filter rules
$gump->filter_rules([
'username' => 'trim|sanitize_string',
'password' => 'trim',
'email' => 'trim|sanitize_email',
'gender' => 'trim',
'bio' => 'noise_words'
]);
// on success: returns array with same input structure, but after filters have run
// on error: returns false
$valid_data = $gump->run($_POST);
if ($gump->errors()) {
var_dump($gump->get_readable_errors()); // ['Field Somefield is required.']
// or
var_dump($gump->get_errors_array()); // ['field' => 'Field Somefield is required']
} else {
var_dump($valid_data);
}
```
:star: Available Validators
---------------------------
**Important:** If you use Pipe or Semicolon as parameter value, you **must** use array format.
```php
$is_valid = GUMP::is_valid(array_merge($_POST, $_FILES), [
'field' => 'regex,/partOf;my|Regex/', // NO
'field' => ['regex' => '/partOf;my|Regex/'] // YES
]);
```

#### Other Available Methods
```php
/**
* Setting up the language, see available languages in "lang" directory
*/
$gump = new GUMP('en');
/**
* This is the most flexible validation "executer" because of it's return errors format.
*
* Returns bool true when no errors.
* Returns array of errors with detailed info. which you can then use with your own helpers.
* (field name, input value, rule that failed and it's parameters).
*/
$gump->validate(array $input, array $ruleset);
/**
* Filters input data according to the provided filterset
*
* Returns array with same input structure but after filters have been applied.
*/
$gump->filter(array $input, array $filterset);
// Sanitizes data and converts strings to UTF-8 (if available), optionally according to the provided field whitelist
$gump->sanitize(array $input, $whitelist = null);
// Override field names in error messages
GUMP::set_field_name('str', 'Street');
GUMP::set_field_names([
'str' => 'Street',
'zip' => 'ZIP Code'
]);
// Set custom error messages for rules.
GUMP::set_error_message('required', '{field} is required.');
GUMP::set_error_messages([
'required' => '{field} is required.',
'valid_email' => '{field} must be a valid email.'
]);
```
### Creating your own validators and filters
Adding custom validators and filters is made easy by using callback functions.
```php
/**
* You would call it like 'equals_string,someString'
*
* @param string $field Field name
* @param array $input Whole input data
* @param array $params Rule parameters. This is usually empty array by default if rule does not have parameters.
* @param mixed $value Value.
* In case of an array ['value1', 'value2'] would return one single value.
* If you want to get the array itself use $input[$field].
*
* @return bool true or false whether the validation was successful or not
*/
GUMP::add_validator("equals_string", function($field, array $input, array $params, $value) {
return $value === $params;
}, 'Field {field} does not equal to {param}.');
// You might want to check whether a validator exists first
GUMP::has_validator($rule);
/**
* @param string $value Value
* @param array $param Filter parameters (optional)
*
* @return mixed result of filtered value
*/
GUMP::add_filter("upper", function($value, array $params = []) {
return strtoupper($value);
});
// You might want to check whether a filter exists first
GUMP::has_filter($rule);
```
Alternately, you can simply create your own class that extends GUMP. You only have to have in mind:
* For filter methods, prepend the method name with "filter_".
* For validator methods, prepend the method name with "validate_".
```php
class MyClass extends GUMP
{
protected function filter_myfilter($value, array $params = [])
{
return strtoupper($value);
}
protected function validate_myvalidator($field, array $input, array $params = [], $value)
{
return $input[$field] === 'good_value';
}
}
$validator = new MyClass();
$validated = $validator->validate($_POST, $rules);
```
Global configuration
--------------------
This configuration values allows you to change default rules delimiters (e.g.: `required|contains,value1;value2` to `required|contains:value1,value2`).
```php
GUMP::$rules_delimiter = '|';
GUMP::$rules_parameters_delimiter = ',';
GUMP::$rules_parameters_arrays_delimiter = ';';
```
