esc_sql() WP 1.0

Escapes data for use in a MySQL query.

Usually you should prepare queries using wpdb::prepare(). Sometimes, spot-escaping is required or useful. One example is preparing an array for use in an IN clause.

NOTE: Since 4.8.3, '%' characters will be replaced with a placeholder string, this prevents certain SQLi attacks from taking place. This change in behaviour may cause issues for code that expects the return value of esc_sql() to be useable for other purposes.

No Hooks.

Return

String/Array. Escaped data

Usage

esc_sql( $data );

$data(string/array) (required)

Unescaped data

Code of esc_sql: wp-includes/formatting.php ^{VER 4.9.8}

<?php
function esc_sql( $data ) {
	global $wpdb;
	return $wpdb->_escape( $data );
}
