Usage

Add this to the component section of your main config.

'components' => [
    ...
    'sanitizer' => [           
        'class' => 'raditzfarhan\Yii2Sanitizer\Sanitize',                   
    ],
    ...
],

Examples

Filters an array on inputs

// data to be filtered
$data = [
    'name' => ' Farhan"',
    'address' => '<p>No 1, Residence ABC</p>',
    'postcode' => '81221A',
    'points' => '-152.1711B',
    'status' => 'C1',
];

// create a filters corresponding to the input data array
$filters = [
    'name' => ['trim', 'escape'],
    'address' => ['trim', 'escape', 'cast:string'],
    'postcode' => ['digit'],
    'points' => ['digit'],
    'status' => ['cast:int'],
];

// call sanitize function to filter an array of inputs
$filtered_data = Yii::$app->sanitizer->sanitize($data, $filters);
var_dump($filtered_data);

Results in:

[
    'name' => 'Farhan\\\"'
    'address' => 'No 1, Residence ABC'
    'postcode' => 81221
    'points' => -152.1711
    'status' => '1'
]

Usage is fairly simple. Your filter array needs to match the data array with the filters as the array value. You can combine the filters and it will be executed in order from left to right.

Filter single value

// call filter function to filter a single value. You can add filter type as the second argument.
$filtered_data = Yii::$app->sanitizer->filter('<p>No 1, Residence ABC</p>', ['trim', 'cast:string']);
echo $filtered_data;

Results in:

No 1, Residence ABC

The first argument would be the value that needs filtering. The second argument would be the filters that needs to be applied.

Available Filters

Here are the filters that you can use:

Filter	Description
cast	Cast given value into given type. Options are int, float, string.
digit	Will removes non-digit from given value.
encode	Escaping unwanted tags and only output plain HTML using Yii2 HTML:encode() function.
escape	Quote string with slashes using filter_var (FILTER_SANITIZE_MAGIC_QUOTES) function.
float	Removes unwanted characters and remain a float number only. Similar to cast:float.
int	Removes unwanted characters and remain a integer number only. Similar to case:int.
purify	Purify HTML content using Yii2 HtmlPurifier::process() function. Note that HtmlPurifier processing is quite heavy so use with caution.
strip_tags	Removes HTML tags from given string value.
trim	Trims a string and remove white spaces.
