# Stock Manager Developer Hooks and Filters

This developer reference for [Products Stock Manager with Excel for WooCommerce](https://wpfactory.com/item/products-stock-manager-with-excel-for-woocommerce/) lists its filter, actions, cron event, schedules and stored options. The admin screen is at **WPFactory > Stock Manager**. Everything here was verified against Stock Manager Pro 4.0.3.

## Filters

| Filter | Default | Description |
| --- | --- | --- |
| `wpfactory_wc_sm_pro_curl_disable_ssl` | `false` | Return `true` to turn off SSL host and peer verification when the scheduled import downloads the Remote Excel URL with cURL. Use it only for a trusted source with a broken or self-signed certificate. Added in 4.0.1. |

```
// Allow the scheduled import to download from a server with a self-signed certificate.
add_filter( 'wpfactory_wc_sm_pro_curl_disable_ssl', '__return_true' );
```

## Actions and cron

| Hook | Type | Description |
| --- | --- | --- |
| `updateWithCron` | WP-Cron event | Runs the scheduled import from the Remote Excel URL. Scheduled when settings are saved with Auto Import with Cron set to Yes and a frequency selected. Cleared when Auto Import is set to No or the plugin is deactivated. |
| `wpfactory_wc_sm_pro_output_settings` | Action | Fires when the Stock Manager admin page renders. The plugin uses it to output its tabs. |

With WP-CLI you can trigger an import immediately:

```
wp cron event run updateWithCron
```

## Cron schedules

Stock Manager registers these intervals through the `cron_schedules` filter when they do not already exist:

| Key | Interval |
| --- | --- |
| `1min` | 60 seconds |
| `5min` | 300 seconds |
| `10min` | 600 seconds |
| `30min` | 1,800 seconds |
| `1hour` | 3,600 seconds |
| `6hours` | 21,600 seconds |
| `12hours` | 43,200 seconds |
| `daily` | 86,400 seconds |
| `weekly` | 604,800 seconds |
| `monthly` | 2,592,000 seconds (30 days) |

## AJAX actions

| Action | Purpose |
| --- | --- |
| `update_products` | Processes an uploaded .xlsx file. Requires the `update_products` nonce and the Administrator role. |
| `smwpro_exportProducts` | Returns export table rows in batches. Requires the `columnsToShow` nonce and the Administrator role. |

## Product data written

Updates write post meta directly with `update_post_meta()`, then refresh the post's modified date (and the parent's for variations) and call `wc_delete_product_transients()`:

- `_stock`, and `_stock_status` (set to `instock` when stock is above 0, or taken from the status column)
- `_regular_price`, `_sale_price` and `_price`

Because meta is written directly, WooCommerce stock change actions such as low stock notifications are not triggered by these updates, and `_manage_stock` is never changed.

## Options

All settings are stored as options with the prefix `stockManagerWooCommercePro`, for example `stockManagerWooCommerceProupdateStockNumber` and `stockManagerWooCommerceProimportUrl`. The full list is in the [Stock Manager settings reference](https://wpfactory.com/docs/stock-manager-settings-reference/).
