Increase product variation limit in woocommerce

Question

I want to increase the product variation limit in woocomerce.

In existing woocommerce code, The product variation limit is 100.

$limit = apply_filters( ‘woocommerce_rest_batch_items_limit’, 100, $this->get_normalized_rest_base() );

I changed the existing code product variation limit as 100 to 200.

$limit = apply_filters( ‘woocommerce_rest_batch_items_limit’, 200, $this->get_normalized_rest_base() );

It works but when I update my woocommerce plugin existing code changes are removed.

So I want that changes in function.php file. How to do it.

Base Code ( wordpress/plugin/woocommerce/includes/abstract/abstract-wc-rest-controller )

protected function check_batch_limit( $items ) {
    $limit = apply_filters( 'woocommerce_rest_batch_items_limit', 100, $this->get_normalized_rest_base() );
    $total = 0;

    if ( ! empty( $items['create'] ) ) {
        $total += count( $items['create'] );
    }

    if ( ! empty( $items['update'] ) ) {
        $total += count( $items['update'] );
    }

    if ( ! empty( $items['delete'] ) ) {
        $total += count( $items['delete'] );
    }

    if ( $total > $limit ) {
    /* translators: %s: items limit */
        return new WP_Error( 'woocommerce_rest_request_entity_too_large', sprintf( __( 'Unable to accept more than %s items for this request.', 'woocommerce' ), $limit ), array( 'status' => 413 ) );
    }

    return true;
}

This is what the apply_filters() call is for. It's a hook that lets you modify the value.

In this case you want to use add_filter() with the woocommerce_rest_batch_items_limit hook name as the first argument, and then a callback function that returns a modified value:

function wpse_304237_rest_batch_items_limit( $limit ) {
    $limit = 200;

    return $limit;
}
add_filter( 'woocommerce_rest_batch_items_limit', 'wpse_304237_rest_batch_items_limit' );

Hooks are the main way themes and plugins integrate with WordPress and eachother, so if you want to start doing custom development on WordPress or WooCommerce I'd make learning them a priority.

We resolve the problem. We created the new plugin named as product-variation-limit-plugin and after then create a new file name as product-variation-limit-plugin.php. Added below code inside of the PHP file.

http://woocommerce.com description: This plugin is used for increase the product variation limit while export product from odoo to woocommerce Version: 1.0 Author: Sodexis PVT Ltd Author URI: http://woocommerce.com License: GPL2 */

function wpse_rest_batch_items_limit( $limit ) {
    $limit = 200;

    return $limit;
}
add_filter( 'woocommerce_rest_batch_items_limit', 'wpse_rest_batch_items_limit' );

We checked on it. The problem was product variant is not synced from Odoo to woo commerce so we created this plugin. It is working properly.
