Usage
global $wpdb; $wpdb->delete( $table, $where, $where_format );
- $table(string) (required)
- Table name.
- $where(array) (required)
- A named array of WHERE clauses (in column => value pairs). Multiple clauses will be joined with ANDs. Both $where columns and $where values should be "raw". Sending a null value will create an IS NULL comparison - the corresponding format will be ignored in this case.
- $where_format(array|string)
- An array of formats to be mapped to each of the values in $where. If string, that format will be used for all of the items in $where. A format is one of '%d', '%f', '%s' (integer, float, string). If omitted, all values in $data will be treated as strings unless otherwise specified in wpdb::$field_types.
Default: null
