README

Additional sanitization functions that complement WordPress core. These functions follow WordPress naming conventions and feel like native functions that should exist in core.

Installation

composer require arraypress/wp-sanitize-polyfills

Functions

sanitize_object_ids

Sanitize an array of object IDs (post IDs, term IDs, user IDs, etc.).

$ids = sanitize_object_ids( [ '1', 2, '3', 0, '', 2, 'abc' ] );
// Returns: [ 1, 2, 3 ]

sanitize_amount

Sanitize a monetary/decimal amount.

$price = sanitize_amount( '$1,234.567' );
// Returns: '1234.57'

$price = sanitize_amount( '99.9', 0 );
// Returns: '100'

$price = sanitize_amount( '-45.5', 2 );
// Returns: '-45.50'

sanitize_comma_list

Sanitize a comma-separated list into an array.

$tags = sanitize_comma_list( 'apple, banana, , cherry' );
// Returns: [ 'apple', 'banana', 'cherry' ]

sanitize_newline_list

Sanitize a newline-separated list into an array.

$lines = sanitize_newline_list( "line one\nline two\n\nline three" );
// Returns: [ 'line one', 'line two', 'line three' ]

sanitize_emails

Sanitize a list of email addresses. Accepts comma-separated string, newline-separated string, or array.

// From comma-separated string
$emails = sanitize_emails( 'john@example.com, invalid, jane@example.com' );
// Returns: [ 'john@example.com', 'jane@example.com' ]

// From array
$emails = sanitize_emails( [ 'john@example.com', 'not-an-email', 'jane@example.com' ] );
// Returns: [ 'john@example.com', 'jane@example.com' ]

is_valid_json

Check if a string is valid JSON.

is_valid_json( '{"name": "John"}' );  // true
is_valid_json( 'not json' );           // false
is_valid_json( '' );                   // false
