wpdb::add_placeholder_escape() WordPress Method

The wpdb::add_placeholder_escape() method is a helper method for safely adding placeholder values to SQL queries. Placeholder values are replaced with the corresponding real values when the query is executed, and this method ensures that the placeholder values are properly escaped for safe use in a SQL query.

wpdb::add_placeholder_escape( string $query ) #

	public function add_placeholder_escape( $query ) {
		/*
		 * To prevent returning anything that even vaguely resembles a placeholder,
		 * we clobber every % we can find.
		 */
		return str_replace( '%', $this->placeholder_escape(), $query );
	}
