wpdb::_insert_replace_helper() │ public │ WP 3.0.0

Helper function for insert and replace.

Runs an insert or replace query based on $type argument.

Method of the class: wpdb{}

No Hooks.

Return

Int|false. The number of rows affected, or false on error.

Usage

global $wpdb;
$wpdb->_insert_replace_helper( $table, $data, $format, $type );

$table(string) (required)

Table name.

$data(array) (required)

Data to insert (in column => value pairs). Both $data columns and $data values should be "raw" (neither should be SQL escaped). Sending a null value will cause the column to be set to NULL - the corresponding format is ignored in this case.

$format(array|string)

An array of formats to be mapped to each of the value in $data. If string, that format will be used for all of the values in $data. 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

$type(string)

Type of operation. Possible values include 'INSERT' or 'REPLACE'.
Default: 'INSERT'
